The size of Taobao main picture video produced by most people does not meet the official requirements, but this is not a big problem, because it can be cropped according to the standard size of Taobao main picture video through some later video editing.

The tutorial is as follows:

After installing the above video size modification software, let's cut the crap and get straight to the point~(≧▽≦)/~, open the software, click the [Add Video] button or directly drag and drop the video file with the mouse to complete the addition.

Next, click the Advanced Settings button to enter the Advanced Settings panel, where the audio and video encoder, output audio and video quality, size, bit rate, frame rate and other related parameter settings are listed. The other defaults are not a big deal. Just modify the video size. Click the drop-down box button of the video size. The video size modification software provides the current mainstream resolutions for you to choose. You can also modify the resolution yourself, such as changing it to 800x800.

After the resolution modification is completed, click OK to return to the main interface and take a look at another convenient function of the software: click the [Video Edit] button above, which changes from dark to bright, to enter the video editing panel, where you can cut video clips, cut video black edges, add watermarks, merge videos, adjust brightness, contrast, and other editing. Click the [Cut] option, and a dotted box for cropping will appear in the original video preview window above. Use the mouse to crop the screen size you need, or directly enter the crop size parameters in the panel below. You can crop the length and width of the Taobao main picture video to 1:1.

Then set the output video format. Taobao officials have not clearly stated what formats are not supported. You can modify the software's default mp4 format according to the video size. If you have a hobby of a dedicated format, you can click the preset plan to select the output video format. The software provides almost all current audio and video formats for conversion. You can convert whatever format you like and have fun.

Finally, in order to prevent the output video file from being found after generating a new video, you'd better change the output path, and then click the round button in the lower right corner of the software interface to start generating a new video that has been cropped to the standard size of the Taobao main picture video.
