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.

Create a 20-second 9:16 video from my your original YouTube source file and the desired output shape. Reframe the chosen segment around the key action while retaining the context. Use my supplied wording for titles. Use the source file and verify that the crop does not hide the subject of the explanation.

Make the next version more specific

Use the source file and verify that the crop does not hide the subject of the explanation.

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.
