<div dir="ltr"><div>Hi <br></div><div><br></div><div>To third Camille's suggestion I also recommend to reduce the preview resolution. Ever since that feature was introduced I stopped using proxies. I can't recall a bad experience with proxies besides the disk space, fortunately for 20.08 JBM added an interface to manage the generated proxies.

<div>Hi Mehdi, <br>
</div>
<div><br>
</div>
<div>Thanks for the kind words about
kdenlive :-).</div>
<div>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.</div>
<div>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.</div>
<div>Cheers,</div>
<div>Camille <br>

problem though, Kdenlive is bad at previewing in-edit tracks
