How to trim Facebook video files with AI

Keep one complete point and remove unrelated material before and after it.

Start with the moments that tell the story

Bring your original source recording for a Facebook post. 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

Keep one complete point and remove unrelated material before and after it.

Try a 30-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.

Create a 30-second 9:16 video from my your original source recording for a Facebook post. Keep one complete point and remove unrelated material before and after it. Use my supplied wording for titles. Upload a source file and check that the retained segment makes sense without the original post.

Make the next version more specific

Upload a source file and check that the retained segment makes sense without the original post.

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.
