Design the cover, keep the edit
Append a custom still as the last frames instead of rebuilding the timeline just to get a usable Studio thumbnail.
macOS · local processing
Append the cover frame YouTube will not give you.
Drop a reel and a cover image. The app appends your thumbnail as the final frames so YouTube Studio can select the cover you designed — without reopening the edit.
Why it exists
The cover frame Studio will not invent for you.
Match the source honestly
Encoding profiles follow the original clip — including HEVC and HDR metadata when the source needs it.
Stay local
No upload step, no account gate for processing. The work happens on the machine that already has the footage.
