Frequently asked questions

How do I create the Runway Reunion AI video?

Upload one reference for the person starting on the left and one for the person starting on the right. Select the resolution and generate a 10-second video using the source reunion motion.

Do left and right refer to the start or end of the clip?

They refer to the opening frame. The prompt keeps each reference assigned to that performer as the people move, meet and overlap.

Can I use two photos of the same person?

The template is designed for two separate characters. Use one clear reference for each person to help avoid mixed identities; this is not a two-outfit transformation template.

Does the template replace the airplane or the background?

No. The requested replacements are the two main characters. The source runway setting, airplane movement, camera motion and reunion timing are retained.

What should the two character photos show?

Use sharp, well-lit photos with an unobstructed face and visible appearance. Each photo guides its assigned person’s face, hair, proportions and visible clothing. Exact identity and garment matches are not guaranteed.

How long does generation take, and can I leave the page?

Generation time depends on the provider and its queue; no fixed completion time is promised. You can leave after the request is submitted. Check Studio for processing status and the finished video.

What should I do if generation fails or is being checked?

Check Studio and Credit activity for the job status and any returned credits. If the status says the result is being checked, do not submit the same video again yet; contact support@retwist.ai with the job ID.

Will the result match the preview exactly?

The preview demonstrates the intended effect. AI generation can change faces, motion, clothing, product detail and text. An exact match is not guaranteed. Review your finished video before sharing it.
