*2 Even if a video meets this limit, it may result in an error if there is a large amount of conversation or activity.
Please remove unnecessary parts or split the video into 10-20 minute segments.

*3 Even if the file extension matches, audio-only files without images (pictures, videos, animations) cannot be registered.

*4 Videos with "AV1" codec cannot be registered on any device.

  • Even if the video meets the restrictions, it may not be possible to upload depending on how the video was created and edited.
    When preparing multiple or paid images/videos, 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, as well as your environment, you may need to wait for a long time for video processing.
    If processing takes too long, please consider canceling the process, shortening the original video, and re-registering it.

*5 When using semi-automatic generation from videos already registered to covers or steps, they can be used regardless of the original video's file extension.
