Hi, issue is pretty much what I described in the title. kdenlive render process is all fine and complete successfully each time but the rendered video turns black in the last quarter part. I have tried several times with some other mp4 files as well. The thing is that I need to edit a mp4 video file and then render into a mp4 file again, so I didn't bother to try other formats.
The specs are kdenlive v17.04.02 - running on debian 9.1 KDE 5
Any advice would be appreciated.

Make sure you have not selected Hide video on the Track Header of one of your video tracks https://userbase.kde.org/Kdenlive/Manua ... e#Timeline
