What’s the difference between Unlimited and credit-based generation?
At matching model and output settings, both use the same generation quality. The Unlimited runs do not deduct credits and may wait longer, while credit-based runs use credits and receive priority.
Can I export videos without watermarks to edit in CapCut or Premiere Pro?
Yes, with a VerseIn plan that includes watermark-free export. Download the supported video file and import it into CapCut or Premiere Pro for further editing.
Why did my generation fail, or why does my character look warped?
Possible causes include unsupported files, conflicting references, complex interactions, processing errors or content checks. Use clearer references and simplify the action; for character swaps, check that the subject and motion are easy to identify. Some requests may be restricted by copyright or likeness protections. Use authorized music and footage, and obtain consent for real people’s images or likenesses. Check the error message before retrying; simplification cannot guarantee a fix.
