--- Comment #1 from Jonathan Gilbert <c6kargn...@liamekaens.com> --- I have been reviewing the background of this report and tried to reproduce a previous Kdenlive version producing an MKV file as I remembered. From fresh installations of 17.12 and 18.12.2, I saw the same behaviour as 19.08, ignoring the f="mkv" in the format specification and writing an MP4 container into the output file despite happily giving it the .mkv extension. I poked a bit deeper and found the avformat presets files in ./share/mlt off the installation folder. The x264 presets in this directory (and, I'm sure, others as well) include a directive "f=mp4" at the top of the file, and I found that if I edit this to "f=mkv" in the preset file, I get the desired behaviour I want. I conjecture that my experience in the distant past was with an installation that had been modified in this way, which is how I have memories of Kdenlive writing MKV files. So, this changes this bug report, but it does not obviate it. It is not a regression; rather, Kdenlive never did allow the user to specify the output format, even though it does invite you to set up your own render format definitions, in which "f=mkv" is accepted syntax and "mkv" can be specified for the file extension. -- You are receiving this mail because: You are watching all bug changes.
