Hello.

Can you add 'qtrle' screen grab encoding profile?

Currently Kdenlive has two screen grab profiles: x264 and x264 mute.
x264 codec is very effective, but consumes more CPU.

I use qtrle for screen grab - it consumes much more disk space, but less CPU.
Can you add it to default configuration?
