If you want the video you are editing not to be compressed, or the compression range is not so large, there are several methods.

First, the original material must be high-definition, so that the edited work is high-definition even if it is compressed.

Second, when editing in editing software, try to set the frame rate consistent with the video format.

Third, before exporting the video, adding some sharpness to the video material can improve the definition of the compressed video, but if you add it in moderation, you will feel uncomfortable in the later stage of the video.

Fourth, after the video is exported, it is recommended to upload the video with the web version of Tik Tok, because the URL sent here will be swallowed up, so it will not be sent here.

The more, the more meaningful. You can read the comment area and communicate with each other if necessary.
