--- Comment #2 from S. Christian Collins <s_chriscoll...@hotmail.com> --- Removing "f=mkv" fixes the red X and error message, but then rendering crashes with the following message: medium: [ ref=1, _mlt_properties_load=medium, __mlt_properties_load=medium ] [mp4 @ 0x7f96140c6e00] Could not find tag for codec flac in stream #1, codec not currently supported in container [consumer avformat] Could not write header '/home/chris/Desktop/Quick Access/Current Project/my video file.mkv' So, I tried adding "f=matroska" instead (which does show up in ffmpeg's list of supported formats), and it works! No more error from kdenlive, and everything renders properly. It appears that "f=mkv" actually works with ffmpeg, but isn't listed in the supported formats, hence Kdenlive throwing the error based on whatever check it does. -- You are receiving this mail because: You are watching all bug changes.
