Good morning all

I'm looking to launch the command line generation of a video from a MLT extension script file generated by kdenlive. I am a Windows 10 user

Example:
C:\kdenlive\bin\kdenlive.exe -renderqueue project-test.mlt
> this command is not correctle.

Thank you in advance
Thierry

Salut
You have to use the "melt" executable, with only argument the .mlt playlist, to get the final render.
Note: if you run "melt" on your .kdenlive project, it will just play it and not save the result to a file, as it does not embed the "consumer" element defining the render output, it is added at export stage.

Thanks vpinon, Merci
For my example, use

Code: Select all

set melt=C:\Kdenlive\kdenlive\bin\melt.exe
%melt%  project-test.mlt -consumer avformat:test.mp4 f=mp4 movflags=+faststart vcodec=libx264 progressive=1 g=15 bf=2 crf=15 acodec=aac ab=256k


command executes well, but does not automatically generate video "test.mp4". why ?

Below, the screenshot of the execution result



if you press successively the space key. The video file is generated.
does the notification "Using AVStream.codec to pass codec parameters to muxers is deprecated..." block the generation?

Regards
