Q1. Can you crop a TikTok video before posting?
Yes. You can crop a video before posting it by using the TikTok mobile app's built-in editing tools. However, the TikTok web version does not currently offer a video cropping feature, so you will need to crop the video with another editor before uploading it.
Q2. Will cropping a video affect its file size?
Yes, cropping a video can change its file size. Removing unwanted parts of the frame may reduce the overall file size. However, if the video is re-encoded during the cropping process, the file size may slightly increase depending on the output settings.
Q3. Is the 4:5 aspect ratio supported by TikTok?
Yes, TikTok supports videos with a 4:5 aspect ratio. However, TikTok may automatically add black bars to fit the full-screen display. For a better viewing experience and a more professional look, it is recommended to crop TikTok videos to the 9:16 vertical format.
