[0024] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0026] The existing special effects processing is not good. For example, some special effects are difficult to show obvious effects on certain videos, or such videos may be overexposed and have poor viewing experience. The inventor found that the main reason is that the parameters used by the existing special effects are all preset fixed parameters, and the special effects processing method is undifferentiated for all videos. However, different videos have different acquisition devices, acquisition environments, video editing and other factors, so most videos generally have certain differences in visual attribute information such as brightness, exposure, contrast, etc., and the effects obtained by applying the same special effect will also be different, especially for luminous / color-changing special effects, which have great differences in performance under different light / color environments. For example, such special effects are prone to overexposure when applied to video frames with high exposure, while the effect is almost not shown when applied to video frames with low exposure. Only when applied to video frames with moderate exposure can the special effects be better presented. For example, for line light speed change special effects, it can present the effect of luminous lines on the image, mainly by identifying the highlight area on the image, and applying luminous lines of varying lengths based on the highlight area to present the line light speed change effect. However, for videos shot in darker environments, it is difficult to identify the highlight area on the video frame image. Therefore, it is difficult to present the line light speed change effect when processing such videos based on the line light speed change special effects. The above are all examples and should not be regarded as limitations. They will not be listed one by one here.

[0027] To improve the above problems, the embodiments of the present disclosure provide a video processing method, device, equipment and medium, which can perform special effects processing on the video in a targeted manner based on the video's own parameters, that is, to achieve dynamic adaptation of special effects and video, thereby ensuring the special effects processing effect. For ease of understanding, the following is a detailed explanation.

[0028] Figure 1 The flowchart of a video processing method provided by an embodiment of the present disclosure is shown in FIG. 1 , which can be executed by a video processing device, wherein the device can be implemented by software and / or hardware and can generally be integrated in an electronic device. Figure 1As shown, the method mainly includes the following steps S102 to S108:

[0029] Step S102, obtaining a first video to be processed, and determining a target special effect to be adopted for the first video.

[0030] Any video that needs to be processed with special effects can be used as the first video. The disclosed embodiment does not limit the type of the first video and the content it contains. Any special effect can be used as a target special effect. The target special effect can be a static special effect such as a filter, or a dynamic special effect, such as creating a rich visual experience by adding visual elements such as animation, lines, particles, halos, shadows, and deformations. The disclosed embodiment does not limit the specific type of the target special effect. In actual applications, when the user edits the first video, a special effect trigger item can be provided to the user. After the user triggers the special effect trigger item, multiple special effect selection items are displayed to the user, and the special effect selected by the user is used as the target special effect to be adopted for the first video.

[0031] Step S104, obtaining a target parameter value corresponding to the first video; wherein the target parameter value is a parameter value corresponding to a target visual attribute related to a target special effect. Visual attributes include but are not limited to any image effects such as brightness, exposure, saturation, contrast, etc., which are not listed one by one here. In practical applications, visual attributes related to various special effects can be pre-set, such as target visual attributes related to luminous special effects, including but not limited to brightness.

[0032] It is understandable that the first video contains multiple video frame images, and the video frame images themselves have multiple visual attributes. When the embodiment of the present disclosure uses the target special effect to process the first video, it can mainly obtain the parameter values ​​corresponding to the target visual attributes related to the target special effect, so as to facilitate subsequent analysis and processing. Optionally, the parameter values ​​corresponding to the target visual attributes can be represented by means, such as brightness mean, saturation mean, etc. The number of target parameter values ​​corresponding to the first video can be one or more groups, and each group of target parameter values ​​includes at least one parameter value corresponding to the target visual attribute. In other words, all parameter values ​​corresponding to the target visual attributes related to the target special effect can be combined and regarded as a group. In some implementation examples, the first video as a whole may correspond to a set of target parameter values. Specifically, the target parameter values ​​corresponding to the first video may be comprehensively determined based on the target parameter values ​​corresponding to each of the video frame images contained in the first video. Considering that the first video to be processed may have transitions, that is, the first video may be spliced ​​together from multiple video clips, and different video clips may correspond to different target parameter values, respectively, in some specific implementation examples, the target parameter values ​​corresponding to the first video include the target parameter values ​​corresponding to the video clips in the first video, that is, a set of target parameter values ​​corresponding to each of the video clips in the first video. In this case, the first video corresponds to multiple sets of target parameter values.

[0033] Step S106, based on the target parameter value corresponding to the first video, determine the special effect parameter value of the target special effect. The disclosed embodiment does not limit the parameters required for the target special effect, which depends on the type of the target special effect. For example, when the target special effect is a line light speed change special effect, the corresponding special effect parameters include luminous intensity parameters, line light length parameters, zoom parameters, etc., which are not listed one by one in the disclosed embodiment.

[0034] In the related art, the special effect parameter value of the target special effect is preset and unchanged, but in the embodiment of the present disclosure, the special effect parameter value of the target special effect can be dynamically determined according to the target parameter value corresponding to the first video, and can be specifically determined based on the mapping relationship between the preset target parameter value and the special effect parameter value. Each group of target parameter values ​​corresponds to a special effect parameter value of the target special effect, and in the case where the target parameter value corresponding to the first video includes the target parameter value corresponding to the video clip in the first video, the special effect parameter value of the target special effect includes the special effect parameter value corresponding to the video clip, that is, each video clip in the first video has a corresponding special effect parameter value of the target special effect.

[0035] Step S108, based on the special effect parameter value of the target special effect, the first video is processed with special effects to obtain a second video. In some implementation examples, if the first video corresponds to only one set of special effect parameter values, the first video as a whole can be processed with special effects based on the special effect parameter values; in other implementation examples, if the first video contains multiple video clips, each of which has a corresponding special effect parameter value, then for each video clip, the special effect can be processed based on the special effect parameter value corresponding to the video clip, and then spliced ​​together to obtain the second video.

[0036] Compared with the method in the related art of uniformly using the same special effect parameters to process all videos indiscriminately, the above method provided by the embodiment of the present disclosure can obtain the parameter value corresponding to the target visual attribute related to the target special effect in the first video, and dynamically determine the special effect parameter value based on the target parameter value, so as to perform special effect processing on the first video in a targeted manner based on the special effect parameter value, fully ensuring the effect of the target special effect on the first video, thereby better ensuring the user's visual perception and special effect usage experience.

[0037] On the basis that the target parameter value corresponding to the first video includes the target parameter value corresponding to the video segment in the first video, the above step S104, i.e., the step of obtaining the target parameter value corresponding to the first video, can be performed with reference to the following steps a to c:

[0038] Step a, obtaining pixel differences between adjacent video frame images in the first video. Exemplarily, the pixel differences can be characterized based on an average value of pixel differences between adjacent video frame images. The disclosed embodiment can effectively and reliably evaluate pixel changes of adjacent video frame images by obtaining pixel differences between two adjacent video frame images in the first video.

[0039] Step b, based on the pixel difference, the first video is subjected to transition recognition processing to obtain the video clips contained in the first video. It is understandable that the pixel difference between the video frame images obtained by shooting in the same scene is usually small, and the pixel difference between the video frame images obtained by shooting in different scenes is large. The pixel difference can be used to measure whether there is a transition in the first video, that is, whether there are multiple video clips. In practical applications, a difference threshold can be preset. When the pixel difference between adjacent video frame images is greater than the difference threshold, it is regarded that the first video has a transition, and the subsequent frame image in the adjacent video frame images is the first frame image after the transition, that is, the first frame image of the new video clip. When the pixel difference between adjacent video frame images is not greater than the difference threshold, it is regarded that no transition occurs, and the adjacent video frame images belong to the same scene. By analyzing the adjacent video frame images in the first video one by one in the above manner, the video clips contained in the first video can be determined. The above method provided by the embodiment of the present disclosure is not only convenient and fast, but also can accurately and reliably obtain all the video clips contained in the first video.

[0040] Step c, obtaining the target parameter value corresponding to the video segment in the first video. In some specific implementation examples, step c can be performed with reference to (1) or (2) as follows:

[0041] (1) Obtain the target parameter value of the first frame image of the video segment in the first video, and use the target parameter value of the first frame image of the video segment as the target parameter value corresponding to the video segment in the first video. It is understandable that, under normal circumstances, the parameters of the various video frame images in the same video segment are not much different, so the target parameter value of the first frame image of each video segment can be directly used as the target parameter value of the video segment. This method of obtaining the target parameter value corresponding to the video segment is more efficient and convenient, and requires less computing resources.

[0042] (2) Obtain the target parameter value of each frame image of the video segment in the first video, and take the average value of the target parameter value of each frame image as the target parameter value corresponding to the video segment in the first video. The target parameter value corresponding to the video segment obtained in this way is obtained by integrating the target parameter values ​​of each frame image, and is more representative. In practical applications, the above (1) or (2) can be flexibly selected according to needs, and is not limited here.

[0043] On the basis of the above, the above step S106, i.e., the step of determining the special effect parameter value of the target special effect based on the target parameter value corresponding to the first video, can be specifically implemented by determining the special effect parameter value of the target special effect corresponding to the video clip based on the target parameter value corresponding to the video clip in the first video and the preset mapping relationship; wherein the preset mapping relationship is used to indicate the association relationship between the target parameter value and the special effect parameter value, such as the target parameter value is the brightness value, the special effect parameter value is the exposure value, and the relationship between the brightness value and the exposure value can be preset, which can be flexibly set and is not limited here. In the above manner, the special effect parameter value of the target special effect corresponding to the video clip can be obtained efficiently and accurately.

[0044] On the basis of the above, the above step S108, i.e., the step of performing special effect processing on the first video based on the special effect parameter value of the target special effect to obtain the second video, can be performed with reference to the following steps A and B:

[0045] Step A, based on the special effect parameter value corresponding to the video segment in the first video, performs special effect processing on the video segment to obtain a special effect segment corresponding to the video segment. In order to further meet user needs, in some specific implementation examples, step A can be performed with reference to the following steps A1 to A2:

[0046] Step A1, obtaining the user adjustment parameter corresponding to the target special effect. The user adjustment parameter can be used to indicate the intensity corresponding to the special effect parameter of the target special effect. In practical applications, a parameter adjustment control of the target special effect can be provided to the user, and the user can use the parameter adjustment control to set the intensity of the special effect parameter of the target special effect. For ease of understanding, please refer to Figure 2 A schematic diagram of a user interaction interface is shown, taking a parameter adjustment control as a slider control as an example, taking a target special effect as a special effect that can present a thermal imaging effect as an example, and the corresponding special effect parameters are speed, size, luminescence and other parameters. In the embodiment of the disclosure, a corresponding slider control is set for each adjustable special effect parameter on the interface, and the user can set the intensity of each special effect parameter through the slider control. In actual applications, the default intensity of the slider control corresponding to each special effect parameter can be pre-set, and the user can also adjust the intensity through the slider control. The intensity adjustment range can be flexibly set, such as 0 to 100%.

[0047] Step A2, based on the special effect parameter value corresponding to the user-adjusted parameter and the video clip in the first video, the video clip is processed with special effects. Specifically, the special effect parameter value corresponding to the video clip in the first video can be adjusted based on the user-adjusted parameter, and the video clip is processed with special effects based on the adjusted special effect parameter value. For ease of understanding, assuming that the first video includes video clip 1 and video clip 2, the target parameter value corresponding to video clip 1 is a brightness value of 255, and the special effect parameter value corresponding to the target special effect can be obtained by the above method. Exposure -10; the target parameter value corresponding to video clip 2 is a brightness value of 100, and the special effect parameter value corresponding to the target special effect can be obtained by the above method. Exposure -3; assuming that the exposure slider corresponding to the target special effect is set to 80% exposure intensity by default, at this time, the special effect parameter value corresponding to video clip 1 is exposure -8, and the special effect parameter value corresponding to video clip 2 is exposure -2.4. Assuming that the user adjusts the exposure intensity to 100% through the exposure slider, the special effect parameter value corresponding to video clip 1 is exposure -10, and the special effect parameter value corresponding to video clip 2 is exposure -3. Assuming that the user adjusts the exposure intensity to 50% through the exposure slider, the special effect parameter value corresponding to the video clip 1 is exposure -5, and the special effect parameter value corresponding to the video clip 2 is exposure -1.5.

[0048] Through the above method, the user-adjusted parameters can be combined with the special effect parameter values ​​obtained based on the video clip, thereby ensuring that the special effect processing results corresponding to the video clip both meet the user's needs and match the video clip.

[0049] Step B: performing splicing processing based on the special effect clips to obtain a second video.

[0050] Specifically, based on the order of each video clip in the first video, the special effects clips corresponding to each video clip can be spliced ​​together to obtain a second video. Through the above-mentioned method, the target special effects can be dynamically matched with the visual attribute information of each video clip, and the second video finally obtained can present a harmonious and stable visual experience to the user as a whole.

[0051] Based on the foregoing, the present disclosure further provides Figure 3 The schematic flow chart of a video processing method shown mainly includes the following steps S302 to S316:

[0052] Step S302, obtaining a first video to be processed, and determining a target special effect to be adopted for the first video.

[0053] Step S304, obtaining pixel differences between adjacent video frame images in the first video;

[0054] Step S306, performing transition recognition processing on the first video based on pixel differences to obtain video segments included in the first video;

[0055] Step S308: Obtain the target parameter value corresponding to each video segment in the first video.

[0056] Step S310, based on the target parameter value corresponding to each video clip in the first video and a preset mapping relationship, determine the special effect parameter value of the target special effect corresponding to each video clip; wherein the preset mapping relationship is used to indicate the association relationship between the target parameter value and the special effect parameter value.

[0057] Step S312, obtaining user adjustment parameters corresponding to the target special effect;

[0058] Step S314: performing special effect processing on each video segment based on the user-adjusted parameters and the special effect parameter values ​​corresponding to each video segment in the first video.

[0059] Step S316, performing splicing processing based on each special effect clip to obtain a second video.

[0060] The above method provided by the embodiment of the present disclosure fully takes into account that the related technology uniformly adopts the same special effect parameters to perform indiscriminate processing on all videos, which may easily lead to poor special effect processing results for some videos. Through the aforementioned method, the special effect parameters can be affected based on the parameter values ​​of the target visual attributes related to the target special effect in the first video, and the special effect processing can be performed on the first video in a targeted manner. Furthermore, the various video clips in the first video can be processed differently to ensure the special effect processing effect of each video clip, realize dynamic adaptation between video and special effects, and fully guarantee the user's visual perception and special effect usage experience.
