Start with the moments that tell the story
Bring birthday photographs arranged by the story you want to tell. 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
Give each photo a clear role and end with the most recent celebration or supplied greeting.
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.

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.
