Hi,
does someone know, how to load a projectfile multithreaded for speeding up this?
I found 1 core running near 100%, all the other sleeping, disk sleeping (most time) too.
Rendering runs very fine on all cores, but not loading...
(i7-9700, SSD + nvme)

opened an issues about this: https://invent.kde.org/multimedia/kdenl ... ssues/1422 it's happening also on Windows. (or are you also on Windows?)

No, thanks god (and these famous guys here with kdenlive!), now Linux only...


Edit:
Just tried the nightly build (208), seems really faster, but still 1 thread I think.
Disk is more busy, maybe I have to optimize my disk-layout.
And, I am not sure, if many threads are helpful if only 1 disk as source...

Edit2:
Loading time here for 22.04 is 115 sec,
Version 22.07.70 (rev. 262872afa) is 100 sec,
build before (208) also 100 sec.
Always the same project.

Hi,
now I'm back, having a quite larger project (>1300 raw clips, >3000 jpegs, many mp3 etc.), timeline for now >20 min. (expected to be > 1,5h).
Loading the project needed > 8 min, if the timeline is up, it still shows around 6000 jobs (thumbnails?) counting down.
Needs some more minutes, but this is multi-threaded.
Most time only 1 core (of eight) is running, disk 50 - 350 MB/s, sometimes <10. No I/O-wait!
My raw footage now resides on a M2-SSD, so a multithreaded loading would greatly speed up the loading.

Any ideas to speed this up?

P.S. The pre-rendering job is also running single-thread only, no matter if multi-thread selected or not (in render-dialog).
