Specifically, the client or server is configured to determine the update time point based on the arrangement position of the target object material in the updated video copy.

[0103] Figure 5 is a schematic diagram of a text display area before and after a paragraph sorting operation provided by an embodiment of the present invention. Specifically, the left side of Figure 5 represents the original video copy displayed in the text display area before the paragraph sorting operation, and the right side represents the updated video copy displayed in the text display area after the paragraph sorting operation. In the example shown in Figure 5, the first paragraph video copy and the second paragraph video copy in the original video copy are paragraph sorted. Before the paragraph sorting operation, the current time point in the time progress bar is the time point corresponding to the "come" in the first paragraph video copy, that is, 00:05. After the paragraph sorting, the updated time point in the time progress bar is the time point corresponding to the "come" in the second paragraph video copy after the paragraph sorting operation, that is, 00:09.

[0104] In an optional embodiment, in response to a text editing operation on the original video copy, an update operation is performed on the original video copy in the video editing interface according to the updated video copy obtained by the text editing operation, including: in response to a paragraph deletion operation on the original video copy, the paragraph video copy corresponding to the paragraph deletion operation is used as the updated video copy, and the updated video copy is deleted from the original video copy in the video editing interface.

[0105] Exemplarily, a paragraph deletion operation may be a user clicking on a paragraph deletion control having a specific icon form in a video editing interface, wherein the paragraph deletion control may be displayed in an editing function navigation area in the video editing interface, or in a calling function navigation area displayed in response to a function calling operation, wherein the function calling operation may be a long press operation or a sliding operation, such as a left sliding operation; the paragraph deletion operation may also be a user clicking on a paragraph deletion option displayed in a floating window in the video editing interface, or a user clicking on a related key on a numeric keypad, wherein the related key may be a backspace key, a delete key, or a predefined key with a paragraph deletion function. The method for generating the paragraph deletion operation is not limited here.

[0106] Based on the above embodiment, correspondingly, the update operation is performed on the original object material in the video editing draft according to the update object material associated with the updated video copy, including: taking the paragraph object material associated with the updated video copy as the update object material, and deleting the update object material from the original object material in the video editing draft.

[0107] Based on the above embodiment, when the video editing interface also includes a material progress bar, the method further includes: replacing the original duration of the video copy in the time progress bar with the updated total duration corresponding to the updated original video copy; wherein the updated total duration represents the difference between the original duration of the copy and the total duration of the updated video copy. For example, assuming the original duration of the copy is 30 seconds and the total duration of the updated video copy is 5 seconds, the updated total duration is 25 seconds.

[0108] In an optional embodiment, in response to a text editing operation on the original video copy, an update operation is performed on the original video copy in the video editing interface according to the updated video copy obtained by the text editing operation, including: in response to a paragraph adding operation on the original video copy, obtaining the newly added paragraph copy corresponding to the paragraph adding operation and the newly added paragraph position relative to the original video copy; according to the newly added paragraph position, displaying the newly added paragraph copy as the updated video copy in the video editing interface.

[0109] Exemplarily, the paragraph adding operation may be an object adding operation of the object material adding control, and correspondingly, the newly added paragraph copy is the video copy transcribed from the added paragraph object material; the paragraph adding operation may also be a click operation input by the user on the paragraph adding control having a specific icon form in the video editing interface, and exemplarily, the paragraph adding control may be displayed in the editing function navigation area in the video editing interface, or may be displayed in the calling function navigation area displayed in response to the function calling operation, wherein the function calling operation may be a long press operation or a sliding operation, such as the sliding operation being a left sliding operation, etc. Exemplarily, the paragraph adding options corresponding to the paragraph adding control include at least one of a manual editing option, an artificial intelligence text editing option, and a text document import option. There is no limitation on the generation method of the paragraph adding operation here.

[0110] Based on the above embodiment, correspondingly, the update operation is performed on the original object material in the video editing draft according to the update object material associated with the updated video copy, including: using the paragraph object material associated with the updated video copy as the update object material; and adding the update object material to the video editing draft according to the newly added paragraph position.

[0111] Specifically, if the paragraph adding operation is an object adding operation of the object material adding control, the updated object material is the paragraph object material corresponding to the object adding operation; if the paragraph adding is a click operation input by the user on the paragraph adding control with a specific icon form in the video editing interface, the updated object material is the black field object material, and the black field material length of the black field object material is the same as the copy paragraph length of the updated video copy.

[0112] Based on the above embodiment, when the video editing interface also includes a material progress bar, the method further includes: replacing the original duration of the video copy in the time progress bar with the updated total duration corresponding to the updated original video copy; wherein the updated total duration represents the sum of the original duration of the copy and the total duration of the updated video copy. For example, assuming the original duration of the copy is 30 seconds and the total duration of the updated video copy is 5 seconds, the updated total duration is 35 seconds.

[0113] Based on the above embodiment, optionally, when the video editing interface also includes time indicators corresponding to each of the paragraph video texts, the method further includes: synchronously updating the indicated time in the time indicator along with the updated video text obtained by the text editing operation.

[0114] The technical solution of this embodiment is to display the original video copy in the video editing draft in the video editing interface; wherein, the video editing draft also includes the original object material associated with the original video copy, and in response to the text editing operation on the original video copy, perform an update operation on the original video copy in the video editing interface according to the updated video copy obtained by the text editing operation, and perform an update operation on the original object material in the video editing draft according to the updated object material associated with the updated video copy, wherein the original object material includes the original video material and / or the original audio material, thereby solving the problem of being unable to perform video editing with the video copy as the editing subject, and improving the video editing efficiency.

[0115] FIG6 is a flow chart of another video editing method provided by an embodiment of the present invention. This embodiment further refines the "text editing operation" in the above embodiment. In this embodiment, the text editing operation includes a text deletion operation and / or a text addition operation. As shown in FIG6 , the method includes:

[0116] S210: Display the original video text in the video editing draft in the video editing interface.

[0117] S210 in this embodiment is the same as or similar to S110 shown in FIG. 1 in the above embodiment, and will not be described in detail in this embodiment.

[0118] S220: In response to a text editing operation on the original video text, an update operation is performed on the original video text in the video editing interface according to an updated video text obtained by the text editing operation.

[0119] S230: Perform an update operation on the original object material in the video editing draft according to the update object material associated with the updated video copy.

[0120] In an optional embodiment, in response to a text editing operation on the original video copy, an update operation is performed on the original video copy in the video editing interface according to the updated video copy obtained by the text editing operation, including: in response to a text deletion operation on the original video copy, the paragraph video copy containing the deleted text corresponding to the text deletion operation is used as the selected paragraph copy; according to the updated video copy obtained by the text deletion operation, a replacement operation is performed on the selected paragraph copy in the video editing interface; wherein, the updated video copy is obtained by deleting the deleted text from the selected paragraph copy.

[0121] For example, the text deletion operation can be a user clicking a related key on the numeric keypad, where the related key can be a backspace key, a delete key, or a predefined key with a text deletion function. The method for generating the text deletion operation is not limited here.

[0122] Specifically, the client or server is used to delete the deleted text from the selected paragraph copy to obtain an updated video copy.

[0123] On the basis of the above embodiment, when the video editing interface also includes a material progress bar and a time indicator, the method further includes: replacing the original duration of the original video copy in the time progress bar with the updated total duration corresponding to the updated original video copy, and replacing the updated paragraph duration corresponding to the updated video copy with the paragraph duration of the copy in the time indicator; wherein the updated total duration represents the difference between the original duration of the copy and the duration of the deleted text, and the updated paragraph duration represents the difference between the paragraph duration of the copy and the duration of the deleted text. For example, assuming that the original duration of the copy is 30s, the duration of the copy paragraph is 10s, and the duration of the deleted text is 1s, the updated total duration is 29s and the updated paragraph duration is 9s.

[0124] Based on the above embodiment, correspondingly, the updating operation is performed on the original object material in the video editing draft according to the updated object material associated with the updated video copy, including: taking the paragraph object material associated with the selected paragraph copy as the selected object material; and performing a replacement operation on the selected object material in the video editing draft according to the updated object material associated with the updated video copy.

[0125] Specifically, when the material type of the selected object material is the first type, the updated object material is obtained by deleting the deleted object material associated with the deleted text from the selected object material; when the material type of the selected object material is the second type, the updated video clip in the updated object material is obtained by performing an end trimming operation on the selected video clip in the selected object material according to the total length of the deleted text corresponding to each deleted text, and the updated audio clip in the updated object material is regenerated according to the updated video text.

[0126] In this embodiment, the selected object material includes a selected video clip and a selected audio clip. The first type is used to indicate that the selected audio clip in the selected object material is the original audio data of the selected video clip or a manually recorded clip. Exemplarily, the video frames of the selected video clip of the first type contain at least a speaking person. The second type is used to indicate that the selected audio clip in the selected object material is a voice-over clip or a digital human audio clip of the selected video clip. Exemplarily, the video frames of the selected video clip of the second type do not contain the speaking person or the subtitles corresponding to the selected paragraph text.

[0127] In one embodiment, the selected object material is of the first type, and the updated object material replaces the selected object material in real time as the text of the original video copy is deleted. Specifically, the client or server is configured to delete the deleted object material from the selected object material to obtain the updated object material, where the updated object material includes an updated video clip and an updated audio clip.

[0128] Specifically, the video editor defines that each punctuation mark in the original video text occupies a time segment with the preceding text. When a text is deleted, the punctuation mark bound to it will be deleted at the same time.

[0129] For example, the text duration t corresponding to a deleted text c Satisfies the formula:

[0130] Among them, t s Indicates the total duration of the selected object material, t b It indicates the duration of the black field in the selected object material, and N indicates the number of words in the selected paragraph copy.

[0131] In another embodiment, the selected object material is of the second type, and the updated object material triggers a replacement of the selected object material in response to a deletion operation triggered by a text deletion control, and the text deletion control is displayed synchronously with a numeric keypad. Specifically, the client or server is configured to perform an end-cropping operation on the selected video segment in the selected object material based on the total duration of the deleted text to obtain an updated video segment, and regenerate an updated audio segment based on the updated video text.

[0132] Figure 7 is a schematic diagram of updating a video segment corresponding to a text deletion operation, provided by one embodiment of the present invention. Specifically, the deleted video segments in the first type of selected video segments are video segments associated with each deleted text, and the deleted video segments in the second type of selected video segments are video segments associated with the end text sequence in the selected paragraph, where the end text sequence contains the same number of characters as the deleted characters.

[0133] In an optional embodiment, the text deletion operation includes a deleting word control in the video editing interface. Exemplarily, the deleting word control can be displayed in the editing function navigation area in the video editing interface, or in the calling function navigation area displayed in response to a function calling operation, wherein the function calling operation can be a long press operation or a sliding operation, such as a left sliding operation.

[0134] In an optional embodiment, the method further includes: if the selected paragraph copy is transcribed from the paragraph object material, the control editing state of the dehydrated word control is set to an editable state; if the selected paragraph copy is not transcribed from the paragraph object material, the control editing state of the dehydrated word control is set to a non-editable state.

[0135] For example, the watermarks in the selected paragraph text may be identified from the selected paragraph text using a watermark recognition algorithm, or may be obtained in response to a watermark marking operation on the selected text. The watermark marking operation may be a user clicking on a watermark marking option displayed in a floating window in the video editing interface.

[0136] In an optional embodiment, in response to a text editing operation on the original video copy, an update operation is performed on the original video copy in the video editing interface according to the updated video copy obtained by the text editing operation, including: in response to a text adding operation on the original video copy, the paragraph video copy containing the newly added text corresponding to the text adding operation is used as the selected paragraph copy, and the newly added text position relative to the selected paragraph copy is obtained; according to the updated video copy obtained by the text adding operation, a replacement operation is performed on the selected paragraph copy in the video editing interface; wherein, the updated video copy is obtained by adding the newly added text to the selected paragraph copy according to the newly added text position.

[0137] Exemplarily, the text adding operation may be an input operation of a numeric keyboard by a user. Specifically, the client or server is configured to add the newly added text to the selected paragraph copy according to the newly added text position to obtain an updated video copy.

[0138] On the basis of the above embodiment, when the video editing interface also includes a material progress bar and a time indicator, the method further includes: replacing the original duration of the original video copy in the time progress bar with the updated total duration corresponding to the updated original video copy, and replacing the updated paragraph duration corresponding to the updated video copy with the paragraph duration of the copy in the time indicator; wherein the updated total duration represents the sum of the original duration of the copy and the duration of the newly added text, and the updated paragraph duration represents the sum of the paragraph duration of the selected video copy and the duration of the newly added text. For example, assuming that the original duration of the copy is 30s, the original paragraph duration is 10s, and the newly added text duration is 1s, the updated total duration is 31s and the updated paragraph duration is 11s.

[0139] Based on the above embodiment, correspondingly, the updating operation is performed on the original object material in the video editing draft according to the updated object material associated with the updated video copy, including: taking the paragraph object material associated with the selected paragraph copy as the selected object material; and performing a replacement operation on the selected object material in the video editing draft according to the updated object material associated with the updated video copy.

[0140] Specifically, when the material type of the selected object material is the first type, the updated object material is obtained by adding the black field object material to the selected object material according to the position of the newly added text, and the object material length of the black field object material is the same as the new text length of the newly added text. When the material type of the selected object material is the second type, the updated video clip in the updated object material is determined according to the total length of the newly added text corresponding to each newly added text and the selected video clip in the selected object material, and the updated audio clip in the updated object material is regenerated according to the updated video copy.

[0141] In one embodiment, the selected object material is of the first type, and the updated object material replaces the selected object material in real time as text is added to the original video copy. Specifically, the client or server is configured to add the black object material to the selected object material based on the position of the newly added text to obtain the updated object material, where the updated object material includes an updated video clip and an updated audio clip.

[0142] In another embodiment, the selected object material is of the second type, and the updated object material replaces the selected object material in response to a triggering addition operation of a text adding control. In this embodiment, the text adding control is displayed synchronously with the numeric keypad. Specifically, the client or server is configured to determine the updated video segment based on the total duration of the newly added text and the selected video segment in the selected object material, and regenerate an updated audio segment based on the updated video text.

[0143] Specifically, if the selected video clip is uploaded to the object display area after being cropped at the end, the cropped video duration corresponding to the selected video clip is obtained; if the cropped video duration is greater than or equal to the total duration of the newly added text, the cropped video clip is spliced ​​at the end of the selected video clip to obtain an updated video clip based on the total duration of the newly added text; if the cropped video duration is less than the total duration of the newly added text, the cropped video clip is spliced ​​at the end of the selected video clip to obtain a reference video clip, and based on the difference between the total duration of the newly added text and the cropped video duration, a black video clip is spliced ​​at the end of the reference video clip to obtain an updated video clip; if the selected video clip has not undergone the end cropping operation, the black video clip is spliced ​​at the end of the selected video clip based on the total duration of the newly added text to obtain an updated video clip.

[0144] Figure 8 is a schematic diagram of an updated video segment corresponding to a text addition operation provided by one embodiment of the present invention. Specifically, a black video segment in the first type of updated video segment is added at the location of the material associated with the newly added text. A preset video segment is spliced ​​at the end of the second type of updated video segment. The preset video segment can be a black video segment, a cropped video segment, or a combination of a cropped video segment and a black video segment. The video duration of the preset video segment is the same as the total duration of the newly added text.

[0145] The technical solution of this embodiment, by responding to the text editing operation on the original video copy, performs an update operation on the original video copy in the video editing interface according to the updated video copy obtained by the text editing operation, and performs an update operation on the original object material in the video editing interface according to the updated object material associated with the updated video copy, thereby solving the problem of synchronous editing of the object material by the text editing operation, further improving the flexibility of video editing, and further broadening the applicable scenarios of the video editing method by distinguishing the material types of the object material.

[0146] FIG9 is a flow chart of another video editing method provided by an embodiment of the present invention. This embodiment further refines the video editing draft in the above embodiment. As shown in FIG9 , the method includes:

[0147] S310: Display the original video text in the video editing draft in the video editing interface.

[0148] S320: In response to a text editing operation on the original video copy, an update operation is performed on the original video copy in the video editing interface according to the updated video copy obtained by the text editing operation.

[0149] S330: Perform an update operation on the original object material in the video editing draft according to the update object material associated with the updated video copy.

[0150] In this embodiment, S310 - S330 correspond to or are similar to S110 - S130 shown in FIG. 1 and / or S210 - S230 shown in FIG. 6 in the above embodiment, and are not described in detail in this embodiment.

[0151] S340. If the preset packaging operation set includes the text editing operation, and the edited video copy corresponding to the text editing operation includes a sequence video copy, then an update operation is performed on the original packaging material in the video editing draft according to the updated packaging material corresponding to the text editing operation.

[0152] In this embodiment, the video editing draft also includes original packaging materials, and the original packaging materials include sequence packaging materials respectively associated with at least one sequence video copy in the original video copy; wherein, the sequence video copy includes a preset sequence copy in at least one paragraph video copy, and each of the preset sequence copies represents a continuous video copy that can span paragraphs, and the sequence packaging materials are used to package the display effect of the sequence object material associated with the sequence video copy.

[0153] Exemplarily, original packaging materials include but are not limited to picture-in-picture, stickers, sound effects, subtitles, music and text templates, among which picture-in-picture, sound effects and music are packaging materials with time attributes, stickers, subtitles and text templates are packaging materials without time attributes, and packaging materials with time attributes represent that the packaging materials themselves have the time attribute of the duration of the packaging materials.

[0154] Specifically, there is an association between the sequence video copy and the sequence packaging material in the timeline dimension. Specifically, the copy time period corresponding to the sequence video copy and the packaging time period corresponding to the sequence packaging material completely overlap on the timeline.

[0155] In an optional embodiment, the preset packaging operation set includes at least one of a paragraph sorting operation, a text deletion operation, and a text adding operation, and the text deletion operation includes a paragraph deletion operation and / or a text deletion operation.

[0156] In an optional embodiment, the updating operation is performed on the original packaging material in the video editing draft according to the updated packaging material corresponding to the text editing operation, including: when the text editing operation is a paragraph sorting operation, at least two paragraph video copywritings corresponding to the paragraph sorting operation are respectively used as selected paragraph copywritings; at least one sequence packaging material associated with a preset sequence copywriting in at least one selected paragraph copywriting is used as a selected packaging material, and the sequence video copywritings respectively associated with each of the selected packaging materials are used as a selected sequence copywriting; according to the updated packaging material corresponding to the paragraph sorting operation, a replacement operation is performed on each of the selected packaging materials in the video editing draft.

[0157] In this embodiment, the updated packaging material is obtained by performing a sorting operation on at least one target packaging material according to the order of the sequence texts. The sequence text order is determined according to the paragraph arrangement order corresponding to the paragraph sorting operation. The target packaging material is determined according to the cross-paragraph attribute of each selected sequence text. Specifically, when the cross-paragraph attribute of the selected sequence text is cross-paragraph, each target packaging material includes split packaging materials associated with at least two split sequence texts, each of which is obtained by performing a paragraph splitting operation on the selected sequence text. When the cross-paragraph attribute of the selected sequence text is non-cross-paragraph, each target packaging material includes the selected packaging material associated with the selected sequence text.

[0158] Specifically, if the selected sequence copy contains preset sequence copy in at least two paragraph video copy, the cross-paragraph attribute of the selected sequence copy is cross-paragraph; if the selected sequence copy contains preset sequence copy in one paragraph video copy, the cross-paragraph attribute of the selected sequence copy is non-cross-paragraph.

[0159] Specifically, if the cross-paragraph attribute of the selected sequence copy is non-cross-paragraph, the selected packaging material associated with the selected sequence copy will be moved along with the paragraph arrangement order of the paragraph video copy; if the cross-paragraph attribute of the selected sequence copy is cross-paragraph, the paragraph splitting operation will be performed on the selected packaging material associated with the selected sequence copy, and the paragraph arrangement order of the paragraph video copy with which the at least two split packaging materials obtained by the splitting are respectively associated will be moved.

[0160] FIG10 is a schematic diagram of an updated packaging material corresponding to a paragraph sorting operation provided by one embodiment of the present invention. Specifically, in the example shown in FIG10 , the selected packaging material is a music material, and the selected sequence texts associated with the selected packaging material include paragraph video text 1 through paragraph video text 4. The paragraph sorting operation represents moving paragraph video text 1 to the back of paragraph video text 3. Since the selected sequence text has a cross-paragraph attribute, a paragraph splitting operation is performed on the selected sequence text based on the paragraph separation positions corresponding to paragraph video text 1 and paragraph video text 2, and the paragraph separation positions corresponding to paragraph video text 3 and paragraph video text 4. This results in three split sequence texts: a combination of paragraph video text 1, paragraph video text 2, and paragraph video text 3, and paragraph video text 4. The target packaging materials associated with each split sequence text are the beginning material, middle material, and ending material of the music material. Based on the sequence text order obtained from the paragraph arrangement order, the sorting operation is performed on each target packaging material, resulting in the order of each target packaging material in the updated packaging material being middle material, beginning material, and ending material, respectively.

[0161] In an optional embodiment, the updating operation is performed on the original packaging material in the video editing draft according to the updated packaging material corresponding to the text editing operation, including: when the text editing operation is a text deletion operation, the sequence packaging material that is associated with the deletion sequence copy corresponding to the text deletion operation is selected as the packaging material; if the selected sequence copy associated with the selected packaging material is included in the deletion sequence copy, the selected packaging material is deleted from the original packaging material in the video editing draft as the updated packaging material; wherein, when the text deletion operation is a paragraph deletion operation, the deletion sequence copy is a deletion paragraph copy, and when the text deletion operation is a text deletion operation, the deletion sequence copy is a deletion text.

[0162] Specifically, if the selected sequence text associated with the selected packaging material is included in the deleted sequence text, it means that the selected sequence text is completely deleted, and the selected packaging material is deleted from the original packaging material in the video editing draft as an updated packaging material.

[0163] In an optional embodiment, the updating operation is performed on the original packaging material in the video editing draft according to the updated packaging material corresponding to the text editing operation, and also includes: if the selected sequence copy is not included in the deleted sequence copy, the replacement operation is performed on the selected packaging material in the video editing draft according to the updated packaging material corresponding to the text deletion operation.

[0164] In this embodiment, when the selected packaging material is a packaging material with a time attribute and the deleted sequence copy does not contain the starting associated text in the selected sequence copy, the updated packaging material is obtained by associating the selected packaging material with the updated original video copy based on the packaging material duration of the selected packaging material and the starting associated text; when the selected packaging material is a packaging material with a time attribute and the deleted sequence copy contains the starting associated text in the selected sequence copy, the updated packaging material is obtained by associating the selected packaging material with the updated original video copy based on the packaging material duration of the selected packaging material and the updated starting associated text, and the updated starting associated text is the first associated text in the selected sequence copy that is located after the deleted sequence copy.

[0165] Based on the above embodiment, optionally, the client or server is also used to: obtain the remaining duration of the remaining video copy starting with the starting associated text or the updated starting associated text in the updated original video copy; if the packaging material duration is greater than the remaining duration of the copy, then perform an end cropping operation on the selected packaging material based on the difference between the packaging material duration and the remaining duration of the copy to obtain the updated packaging material.

[0166] Figure 11 is a schematic diagram of updating packaging materials corresponding to a text deletion operation, provided by one embodiment of the present invention. Specifically, the selected packaging materials shown in Figure 11 include 12 seconds of Music 1 and 14 seconds of Music 2. Music 1 is associated with the text "Hello everyone, the weather is getting hotter recently" in the video paragraph, and Music 2 is associated with the text "Share a good summer sunscreen with you" in the video paragraph.

[0167] In the text deletion operation shown in Figure 11, the deletion sequence copy associated with Music 1 contains the starting associated text "big", and the client or server is used to associate the Music 1 with the updated original video copy according to the packaging material length of the selected packaging material and the updated starting associated text "most". At this time, Music 1 is the 12s packaging material associated with "The weather is getting hotter recently, I'll give it".

[0168] In the text deletion operation shown in Figure 11, the deletion sequence copy associated with Music 2 does not contain the starting associated text "you", so the client or server is used to associate Music 2 with the updated original video copy based on the packaging material duration of the selected packaging material and the starting associated text "you". Since the packaging material duration of Music 2 is greater than the remaining copy duration of the remaining video copy in the original video copy starting with "you", the end cropping operation is performed on Music 2. At this time, Music 2 is a 10-s packaging material associated with "You share a good sunscreen product".

[0169] In this embodiment, when the selected packaging material is a packaging material without a time attribute, the updated packaging material is a packaging material associated with an updated sequence text, and the updated sequence text is obtained by deleting the deleted sequence text from the selected sequence text.

[0170] Before performing a replacement operation on the selected packaging material in the video editing draft according to the updated packaging material corresponding to the text deletion operation, the method further includes: taking the paragraph object material associated with the paragraph video copy where the deletion sequence copy is located as the selected object material; when the text deletion operation is a paragraph deletion operation, or the text deletion operation is a word deletion operation and the material type of the selected object material is the first type, performing the step of performing a replacement operation on the selected packaging material in the video editing draft according to the updated packaging material corresponding to the text deletion operation; when the text deletion operation is a word deletion operation and the material type of the selected object material is the second type, in response to the triggering deletion operation of the word deletion control in the video editing interface, performing the step of performing a replacement operation on the selected packaging material in the video editing draft according to the updated packaging material corresponding to the text deletion operation.

[0171] Specifically, if the text deletion operation is a paragraph deletion operation, or if the text deletion operation is a character deletion operation and the material type of the selected object material is the first type, the updated packaging material replaces the selected packaging material in real time in response to the paragraph deletion operation of the original video copy. If the text deletion operation is a character deletion operation and the material type of the selected object material is the second type, the updated packaging material triggers the replacement of the selected packaging material in response to the triggering deletion operation of the character deletion control.

[0172] In an optional embodiment, the updating operation is performed on the original packaging material in the video editing draft according to the updated packaging material corresponding to the text editing operation, including: when the text editing operation is a text adding operation, the sequence video copy containing the newly added text sequence corresponding to the text adding operation is used as the selected sequence copy, and the sequence packaging material associated with the selected sequence copy is used as the selected packaging material; according to the updated packaging material corresponding to the text adding operation, a replacement operation is performed on the selected packaging material in the video editing draft.

[0173] In this embodiment, when the selected packaging material is a packaging material with a time attribute, the updated packaging material is obtained by associating the selected packaging material with the updated original video copy based on the packaging material duration of the selected packaging material and the starting associated text in the selected sequence copy; when the selected packaging material is a packaging material without a time attribute, the updated packaging material is obtained by associating the selected packaging material with the updated sequence copy based on the starting associated text; the updated sequence copy is obtained by adding the newly added text sequence to the selected sequence copy.
