--- Comment #3 from cont...@jookia.org --- Exporting the project then running using melt gives this error: [libvpx @ 0x7f7ef0001d00] Bitrate not specified for constrained quality mode, using default of 256kbit/sec Changing vb="0" to vb="10M" helps. Exporting the project from a working Kdenlive also gives the same issue and poor output. It looks like this may be a behaviour change in ffmpeg: https://github.com/FFmpeg/FFmpeg/commit/14941d386acd90b92aaaf75fbdac2c07d33f167a Setting 'vb=1M' in the export helps, but it still doesn't look proper. -- You are receiving this mail because: You are watching all bug changes.
