When I try to export as a Movie (.mp4), it just creates a blank (duration 0:01) movie in the default Win10 “Movies” player, or an error in Windows Media Player (“Server execution failed”). Exporting as a GIF, in contrast, works perfectly. Am I doing it wrong, or is this a bug? I am on Windows 10 using the 0.6.6 version.
More details: I created a short animation with about 15 frames. Clicked File>Export>Movie. Clicked Browse and selected file location, changed name from untitled to my name, made sure ended in .mp4, clicked Save, then clicked “OK” on the Export Movie popup screen. Saw a brief “Generating Movie” popup with progress bar, then that disappeared and it said “Finished. Open movie now?”. Clicked Yes and it opens with the Win10 default Movie Viewer and just shows a blank movie with a 1 second duration. If I try to manually open the .mp4 file with Windows Media Player, it pauses for about 30 seconds, then an error appears: “Server execution failed.”
