I have a large amount of content recorded on an iPhone. I then ran that content through Shutter Encoder using default settings for DNxHR HQ. When I add the clips to Kdenlive, K throws errors saying they are VFR and will cause issues.
I converted them primarily to bypass any editing issues, and also to try out Davinci Resolve which doesn’t support VFR at all. More specifically, even with proxies enabled, kdenlive was crashing quite a bit (at least once every editing session, and very frequently if I was adding clips) and producing artifacts in the renders (software render, no hd accel).
Anyone have any ideas? Maybe this doesn’t even matter idk, really just trying to stabilize kdenlive here.
