First of all, thank you very much for maintaining kdenlive.

It has been a great source of fun.

The main reason I'm writing is to humbly suggest re-implementing
its rendering log.

I'd like to use it to find and fix rendering bugs.

I followed the instructions in kdenlive_render's man 
page to create one by setting the environment variable
named "KDENLIVE_RENDER_LOG".

I set it before before trying to render in
kdenlive

    $ export KDENLIVE_RENDER_LOG=1 ; export LANG=C ;  kdenlive

and before running kdenlive_render with a render
script generated by kdenlive

    #! /bin/sh
    RENDERER="/usr/bin/kdenlive_render"
    MELT="/usr/bin/melt"
    SOURCE_0=<a .mlt script>
    TARGET_0=<a .webm file>
    PARAMETERS_0="-pid:7095 in=0 out=1565 $MELT atsc_720p_2997 avformat - $SOURCE_0 $TARGET_0 f=webm vcodec=libvpx acodec=vorbis crf=23 vb=0 quality=good aq=6 max-intra-rate=1000 cpu-used=4 threads=1 real_time=-1"
    KDENLIVE_RENDER_LOG=1
    $RENDERER $PARAMETERS_0

I expected to find a render log file named like

    /tmp/kdenlive_render.log.XXXXXXXX

Unfortunately, I didn't.

I opened Debian bug report 884267.

Patrick Matthäi, who maintains Debian's kdenlive package said he grepped
through the source code, the render log is gone, and I might report a bug here, at kde.org.

Please bring back kdenlive's render log.

I think it would make debugging easier.

Thanks,
Kingsley

Thanks for your report! As far as I know the render log has not been removed. I recently got one. I think it will only be created if the rendering crashes, not if it was successful.

Please check with a recent version (https://kdenlive.org/en/download/) and give some feedback. (You can try to crash the render by aborting the job)

Hi Julius!

Thank you very much for your thoughts on my little
bug report.

If I understand correctly, I did as you asked.

I clicked on the "Abort job" button in the
rendering window of version 20.12.0-2
of kdenlive.

However, I still see no file named like

    /tmp/kdenlive_render.log.XXXXXXXX

I tried it 

    with and 

    without 

exporting KDENLIVE_RENDER_LOG=1 and LANG=C before
running kdenlive.

If it would be convenient, comfortable, and all
those good things, feel free to explain where you
find render logs.

Maybe I looked in the wrong place.

Thanks,
Kingsley

I can find the render log in the same directory as the output file. If I want to  render to to /home/julius/videos/test.mp4 and abort it, I have a file called /home/julius/videos/test.mp4.log
