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, some videos may not be uploadable depending on how they were created or edited.
    If you are preparing a large number of images or videos, or paid content, please prepare a sample video in advance and verify that it can be registered and edited as intended.
  • Depending on the length and size of the video and your environment, you may need to wait a long time for processing to complete.
    If processing does not finish after a long wait, consider canceling the process, shortening the original video, and re-registering it.

*3 When using semi-automatic generation from a video already registered on the cover or a step, it can be used regardless of the file extension of the original video.

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