Created attachment 109801 [details] Batch task exported mitm.exe crashes when trying to render the project. The only output I see is: [webm @ 0000000009efeca0] Using AVStream.codec to pass codec parameters to muxers is deprecated, use AVStream.codecpar instead. [webm @ 0000000009efeca0] Using AVStream.codec to pass codec parameters to muxers is deprecated, use AVStream.codecpar instead. however, removing vcodec=libvpx and acodec=vorbis renders the file (audioless though) Windows 10 (ffmpeg "installed" but not recognised) More details on request :)
Extra output (discovered just now): Started render process: E:/stdedos/Desktop/Kdenlive-17.12.0/melt.exe C:/Temp/kdenlive_rendering_l14984.mlt in=0 out=1354 -profile atsc_1080p_25 -consumer avformat:E:/stdedos/Desktop/NebulaTimelapse2.webm progress=1 f=webm vcodec=libvpx acodec=vorbis crf=15 vb=0 quality=good aq=7 max-intra-rate=1000 cpu-used=4 threads=4 real_time=-1 melt: Current Frame: 1, percentage: 0 melt: Current Frame: 2, percentage: 0 melt: Current Frame: 5, percentage: 0 melt: Current Frame: 12, percentage: 0 melt: Current Frame: 25, percentage: 1 melt: Current Frame: 28, percentage: 2 Rendering of E:/stdedos/Desktop/NebulaTimelapse2.webm aborted, resulting video will probably be corrupted.
I´m using Windows 8.1 and I can confirm stdedos@gmail.com afirmation of: "removing vcodec=libvpx and acodec=vorbis renders the file (audioless though)" But... "removing vcodec=libvpx" AND instead ot removing "acodec=vorbis", replace it by "acodec=libvorbis" (as stated in 388503 and 388696), becoming... miracle!!! Rendering is OK (audio and video). Note 1: The way that I used for changing the rendering settings is to modify the file "...\Kdenlive-17.12.0\data\export\profiles.xml" by using notepad. Note 2: I also had rendering crashes with all codecs. I will test and inform you. Regards.
Please try with the actual Kdenlive version 18.08.2
At the moment only threads=1 is possible. Please try again and let us know.
