Bad preview of 4k video

[Camille Moulin]

Hi Mehdi,

Thanks for the  kind words about kdenlive :-).
About your performance problem, on short term you can try to lower down
the preview resolution (in the lower left corner of the monitor, see
picture attached.)or you can enable proxies.
On the medium/long term, the goal is to be able to use GPU, but this is
quite a large task and needs also to be implemented at MLT's level.
Cheers,
Camille
