I am running the latest kdenlive appimage 19.04.0 (also tried the daily 19.04.1 appimage) on Debian Stretch.

I can not extract a zone from a clip (MP4 container with h.264 video) I mark in and out points, klick "extract zone" and nothing happens - no file is generated, no error is printed in the console. Same thing when trying to save a zone.

Pulling down the zone onto a track works.

Not sure which info is needed to debug this further.

Hello,

Make sure you have selected target tracks. They have a green light on the left of the name of the track (next to "V1" or "A1")

Happy editing.
