[0041] Figure 1 FIG. 1 is a flow chart of a method for adding sound effects according to an embodiment of the present application. Figure 1 As shown, the sound effect adding method of the embodiment of the present application is used for gesture recognition training, including the following steps:
[0042] S101: Obtaining video transition information;
[0043] Video transition refers to the transition or conversion between paragraphs and scenes in a video.
[0044] S102: Reading a transition sound effect from the transition information; and
[0045] In the sound effect adding method provided in the embodiment of the present application, the sound effect information is set in advance in the transition information of the video. Therefore, when the sound effect needs to be matched, the transition sound effect needs to be read from the transition information of the video first.
[0046] S103: Loading the transition sound effect according to the association between the transition information and the transition sound effect.
[0047] After the sound effect is read from the transition information of the video, the transition sound effect needs to be dynamically loaded into the video according to the correlation between the transition information and the transition sound effect, so as to achieve matching between the transition and the sound effect.
[0048] Therefore, in the sound effect adding method provided in the embodiment of the present application, the transition information of the video is first obtained, and then the transition sound effect is read from the transition information, and the transition sound effect is loaded according to the association between the transition information and the transition sound effect. The sound effect adding method provided in the embodiment of the present application realizes the matching of sound effects and transitions through the resources pre-set in the transition information, so that the user no longer needs to look for the corresponding sound effects, thereby improving the video editing efficiency and the user experience.
[0049] Further, in some embodiments of the present application, the reading of the transition sound effect from the transition information includes:
[0050] Obtaining a resource description file from the transition information of the video; and
[0051] The transition sound effect is read from the resource description file.
[0052] Specifically, when the user decides to add a transition, a resource description file is obtained by obtaining relevant transition information. The system converts the description file into recognizable resource information and stores it locally. Then, the corresponding transition sound effect is read through the converted resource information and associated with the corresponding transition, thereby matching the transition with the sound effect. By binding the sound effect with the transition, the user's search / creation of sound effects, as well as sound effect matching and adjustment are reduced, which improves the user's operating efficiency and usage experience.
[0053] Further, in some embodiments of the present application, after obtaining the resource description file from the transition information of the video, the method further includes:
[0054] converting the resource description file into recognizable resource information; and
[0055] The transition sound effect and its associated transition are read from the resource information.
[0056] As mentioned above, when the user decides to add a transition, a resource description file is obtained by obtaining relevant transition information. The system converts the description file into recognizable resource information and stores it locally. Then, the corresponding transition sound effect is read through the converted resource information and associated with the corresponding transition, thereby matching the transition with the sound effect. By binding the sound effect with the transition, the user is reduced to search / create sound effects, match and adjust sound effects, and improve the user's operation efficiency and usage experience.
[0057] Furthermore, in some embodiments of the present application, after obtaining the transition information of the video, the method further includes:
[0058] Determine whether the transition information of the video includes a transition sound effect;
[0059] If yes, reading the transition sound effect from the transition information; and
[0060] If not, the transition is added to the time track of the video.
[0061] That is, when determining whether it is necessary to add a transition sound effect, it is necessary to determine in advance whether the transition information of the video contains the transition sound effect. If so, read the transition sound effect from the transition information; if not, add the transition to the time track of the video, thereby improving the video editing efficiency.
[0062] Furthermore, in some embodiments of the present application, after reading the transition sound effect from the transition information, the method further includes:
[0063] Creating a first data table of the transition information of the video and the transition sound effects associated therewith; and
[0064] Create a second data table for the time track.
[0065] Specifically, each time a transition is added, deleted, checked, or modified, the sound effect transition filter will be entered. At this time, the description information will be read to determine whether it is a sound effect transition. If so, the logical order between the current transition and the associated resources will be recorded in the first data table in the filter. But there is an exception. When a timeline or time track, or a composite clip is created, it will be recorded in the second data table in the filter. When the user is ready to preview or export, the filter will first be associated with the current timeline, and then it will be determined whether the current operation needs to refresh the data by checking whether the first data table of the transition data has been updated. If refresh is required, the current timeline is used as the key to recursively traverse the second data table of the internally maintained timeline and composite clip. During each traversal, the data in the transition data table will be queried to see if it needs to be added to the timeline. If so, the corresponding sound effect resource is created for subsequent playback, so that the user does not need to look for the corresponding sound effect, so as to improve the video editing efficiency and user experience.
[0066] Further, in some embodiments of the present application, loading the transition sound effect according to the association between the transition information and the transition sound effect includes:
[0067] The first data table and the second data table are traversed to load the transition sound effect.
[0068] As mentioned above, when the user is ready to preview or export, the filter will first be associated with the current timeline. Next, the first data table will be traversed to determine whether the first data table of transition data has been updated to determine whether the current operation needs to refresh the data. If a refresh is required, the current timeline is used as the key to recursively traverse the second data table of internally maintained timelines and composite clips. During each traversal, the data in the transition data table will be queried to see if it needs to be added to the timeline. If so, the corresponding sound effect resources are created for subsequent playback, so that the user no longer needs to look for the corresponding sound effects, thereby improving the video editing efficiency and user experience.
[0069] Furthermore, in some embodiments of the present application, after traversing the first data table and the second data table and loading the transition sound effect, the method further includes:
[0070] Add the transition sound effect to the time track.
[0071] That is, when it is determined that a transition sound effect needs to be added, the transition sound effect is added to the time track, thereby completing the editing operation of the video, further improving the video editing efficiency and the user experience.

[0075] The sound effect loading module 230 is used to load the transition sound effect according to the association relationship between the transition information and the transition sound effect.
[0076] In the sound effect adding device provided in the embodiment of the present application, the transition information of the video is first obtained, and then the transition sound effect is read from the transition information, and the transition sound effect is loaded according to the association between the transition information and the transition sound effect.
