Hello all.
First time user here, but long time as an editor in the biz fixing this sort of thing.
Problem.
I'm rendering H265 8K Canon 5C VR 180 footage to PRORES 422LT, using a plugin called STmapper and some KaraVR add ons through Fusion Reactor. (The Hugh Hou method.)
Workflow is to prepare the dailies by adding the STmapper plugin to stitch and export individual files. (ST mapper is performing a warp effect to unwrap the fisheye lens to stretch the frame to a 4 corner square for each eye, in a single frame.)
Delivery will initiate correctly, rendering at around 25 fps, using the GPU to its max capacity, using memory at about 14-16 GB,m and generally leaving all 8 CPU cores pretty unstressed.
Eventually, sometimes after a few minutes, sometimes after a couple of hours, the render frame rate will drop to 1-3 fps, and the GPU CPU workload get swapped around, with all CPU cores maxed out, and the GPU under stressed.
This problem seems to be independent of export frame size, its the same issue whether 4K or 8K.
My only resolution that works is to restart Resolve and kick the render off again.
It's possible I just don't have enough RAM, which is not something I can change, but I thought I'd reach out here and see if it sounds or seems familiar to anyone, and if there are any tips to reduce the memory load on the system while rendering.
Is resolve trying to cache the whole clip for example?
Some of the clips are over an hour long.
Thank you in advance.
