Notes
※1 Even if the file extension matches, files containing audio only without any visual content (video or animation) cannot be registered.
※2 Videos with the "AV1" codec cannot be registered.
- Even if the restrictions are met, the Upload may fail depending on how the video was created or edited.
If you are preparing a large number of images, videos, or paid assets, 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 usage environment, you may need to wait a long time for processing to complete.
If processing is taking too long, 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 to a cover or a Step, it can be used regardless of the original video's file extension.
※4 If the video contains a large amount of dialogue or activity, an error may occur even if the video meets this limit.
Please remove unnecessary sections or split the video into segments of approximately 10 to 20 minutes.
※5 Images of 15 MB or larger can still be registered as sources.
However, since the AI cannot analyze them, they will not be used for Manual creation.
In the source list, a red "!" will be displayed before the File name.
Please reduce the file size by lowering the image resolution or similar methods, then re-register the file.
