Notes

※1 Even if the file extension matches, files containing only audio without any video (moving image or animation) 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, videos, or paid content, please prepare a sample video in advance and verify 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 of lengthy videos.
    If processing does not complete after a long wait, please consider canceling the process once, shortening the original video, and then re-registering it.

※3 When semi-automatically generating content from a video already registered as a cover or in a Step, it can be used regardless of the original video's file extension.

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