Hello there. I am using Kdenlive 0.9.6 in three computers (same version of Linux Mint KDE - my home desktop, laptop and desktop at work). The same project renders OK on my computer at work, but have the same problem on my home computer or laptop: the sections of the video where I applied "Add Effect / Audio Correction / Volume (keyframable)" get MUTED.

When I play the whole project on the preview, everything is OK, audio volumes are like I want them. But on those two computers, the final render has problems. I tried different projects, but got the same issue.

Any tips on what I should look for in order to solve this? I would like to render the projects at home, because that computer has "more juice" than my desktop at work

That is pretty strange.
You could try upgrading versions 0.9.6 is old.
What version of Linux Mint are you on?
Mint is ubuntu based so this ppa might be ok to get a new version from

ttguy, thanks for your reply.

It's really weird, since in one desktop everything works just fine and the others don't.

I just installed kdenvlive 0.9.10 on my home computer (Intel Core i7, 8GB of RAM, nVidia GTX970) and tried rendering that same project I mentioned. Result? No audio in the parts I changed "audio gain".

Again, during the preview on Kdenlive everything is just fine.

Could it be related to melt or ffmpeg? I just checked and their versions are the same I have on my home computer and work computer.

frei0r effects also installed...?

Same version of frei0r-plugins on both desktops.
