3. Restart Kdenlive

Thanks for your report! Unfortunately the movit(gpu) is not very stable at all and it is not really well maintained atm. I am not sure if this will get fixed soon (probably not), but it is definitely some where down the road on our road map!

Perhaps, in agreement with the mlt developers, you could find another well-maintained library that implements the same functions
