When exporting at 50 fps or higher at any resolution using h.264 or mpeg4 (any container) and at any quality, the video file is always black if the edited video contains fading at the start and/or end.
The exported video only displays properly at 30 fps or less.
The bad 'black' exported video file is quite small (e.g. 283.3 kb) as opposed to a 'working' export at 30 fps (e.g. 17.0 MB).
No errors are shown during the export.
The original (imported) video file is 1080p60 h.264.
I have tried playing the exported video back using the Ubuntu 'Videos' app, VLC 2.2.2, Handbrake 1.0.4 and Xine 0.99.9-1.2. All show the same result.
OS: Ubuntu 16.04 64bit
Openshot ver. 2.3.1 (installed via PPA)
FFmpeg (libavcodec) ver. 7:2.8.11-0ubuntu0
Melt ver. 6.0.0-2 |
