Notes

*1 Even if the file extension matches, audio-only files that do not contain video (moving images or animations) cannot be registered.

*2 Videos with the "AV1" codec cannot be registered.

  • Even if the restrictions are met, upload may not be possible depending on how the video was created or edited.
    If you are preparing a large number of images or videos, or paid content, please prepare a sample video in advance to confirm that registration and editing can be performed as intended.
  • Depending on the length and size of the video and your usage environment, you may need to wait a long time for processing to complete.
    If processing does not finish after a prolonged wait, consider canceling the process, shortening the original video, and then re-registering it.

*3 When semi-automatically generating content from a video already registered on a cover page or step, it can be used regardless of the original video's file extension.

*4 If there is a large amount of dialogue or action, an error may occur even with videos that meet this restriction.
Please remove unnecessary sections or split the video into segments of approximately 10 to 20 minutes.
