Ready-to-play video
Title only, transparent
Looks black in QuickTime Player?That's normal: QuickTime Player shows the see-through part as black. Put the file above a clip in Premiere, After Effects, Final Cut, Resolve or Keynote and the clip shows through.
Why is .mov off here?Claude pages can only save .mov files from Claude's own video export, so this button is off here. Open the downloadable copy of this tool (one HTML file, double-click it) and the .mov works.
