Start with the moments that tell the story
Bring your original WebM file and the exact section or adjustment you want. 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 the selected action or spoken passage and remove the surrounding unused footage.
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 WebM file and the exact section or adjustment you want. Keep the selected action or spoken passage and remove the surrounding unused footage. Use my supplied wording for titles. Confirm that the WebM file uploads and decodes correctly. Review the final MP4 for orientation, timing and sound; the output is an MP4, not a lossless rewrite of the source container.
Make the next version more specific

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.
