FAQ
What does this page support?
This page supports both text-to-video and image-to-video workflows, plus optional last-frame guidance when you start from an image.
Why does aspect ratio disappear after I upload a start image?
In image-to-video mode, the provider follows the uploaded image framing, so the page hides aspect ratio instead of pretending it still controls output.
Does the audio switch affect credits?
Yes. Audio generation costs more, so the credit preview updates immediately when you turn it on or off.
