[The Shorty team](https://shortyedit.com/about#editorial-team) · Updated 15 September 2026 ## Key takeaways - Bring source clips and the ranges that should play faster or slower. - Change speed only where requested and preserve important actions or spoken thoughts. - Review the transitions into and out of speed changes and check the audio. ## 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. ## Try this editing prompt Create a 20-second 9:16 video from my source clips and the ranges that should play faster or slower. Change speed only where requested and preserve important actions or spoken thoughts. Use my supplied wording for titles. Review the transitions into and out of speed changes and check the audio. ## Make the next version more specific 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. ## Keep the ideas coming ### Start this edit Explore this editing workflow in Shorty. ### Write a stronger prompt Describe the source footage, audience, format, story order and constraints. Tell Shorty what must remain accurate, which shot should lead and what the viewer should understand at the end. A reference video is optional; a clear written brief can supply the direction. ### Explore revisions Shorty is an AI video editor you can revise by chat. Open an existing edit and describe the change in plain language, such as a new opening, different shot timing or corrected title text, or select an editable title or graphic in the preview and say what should change. Shorty renders a new version to compare with the previous cut. ### Can AI add speed ramps and velocity edits to my clips automatically? Yes. In Shorty you describe the edit, such as “a hype reel of my snowboard trip”, and the director decides which shots ramp and how: fast into a moment, deep into slow motion and back out. It picks from the curves editors use, including Montage, Hero, Bullet, Jump cut, Flash in and Flash out, fills slow stretches with new optical-flow frames and adds motion blur to every speed-up. For music montages it can build a velocity edit that lands each key moment on a beat. You do not set keyframes, and speech never ramps. ## Questions, answered. ### What footage should I use? Source clips and the ranges that should play faster or slower. Choose the takes that support the sequence you want. ### Can I use a different duration or format? Yes. The 20-second 9:16 prompt is a starting point. Describe the length and canvas your video needs, then check the rendered result. ## Your next video starts here. Bring the footage. Tell us the idea. Shape the edit. --- Published by Tools Products FZ-LLC. Canonical HTML: https://shortyedit.com/guides/change-video-speed-workflow
