How to change video speed with AI

Change speed only where requested and preserve important actions or spoken thoughts.

Start with the moments that tell the story

Bring source clips and the ranges that should play faster or slower. Pick the takes that make the subject clear, including a strong opening and a complete ending. These choices give Shorty a useful starting point for the edit.

Give Shorty the creative direction

Change speed only where requested and preserve important actions or spoken thoughts.

Try a 20-second 9:16 edit as a starting point. Include the exact title or closing message you want on screen. Add a reference when you want to show the pace, captions or mood.

Review the transitions into and out of speed changes and check the audio.

Play the first cut and pick the change that would help the story most. Name the moment, describe the result you want and tell Shorty what to keep. A note such as “hold the final product shot longer” gives the revision a clear direction.
