GPU rendering failure [Premiere 2017] - Unable to process frame

Hello everyone,

I know the problem i'll describe below has already many topics... I searched, I read, but never found a working solution and I'm desperate now

1. MY PROBLEM

I'm having troubles trying to render a personal footage of my holidays in 4k (GoPro 4) with GPU rendering enabled (CUDA). Not a very complex montage, but the minimum to make it more professional like : lumetri effects, slowmotion with optical flow, and some nice preset effects zoom in/zoom out transitions from this guy : Premiere Pro Preset: Smooth Transitions | ZOOM + SPIN + SLIDE | - YouTube

I render with Adobe preset : H264 -> Youtube 4k and later on I get the message "Error compiling movie. GPU Render Error Unable to process frame. Writing with exporter: H.264" and don't understand why

2. WHAT I TRIED

I tried to split my projects into smaller chunks, try to pre render scenes, tried in lower definition (like 1080p), tried to render separately juste the small part that fails... but whatever I try, impossible to succeed.

Anyway, I have a pretty nice and configuration, with a good graphical card, so I really don't understand why :

- Adobe premiere cc 2017

- i7 6700k

- GTX 970

- 8Gb RAM

While pre-rendering scenes I got the error too, but if I do it small chunks by small chunks (took me very long time), I successfullly got the green bar on the whole project. But despite that, it seems useless for the final rendering because it re-renders from the beginning and fail.

3. WORKAROUND

The only workaround I found was to disable the GPU rendering. But 2 drawkbacks :

• First of all, it took me sooooooooooo many long time to finish (at least if it was only that... it's not the worst thing)
• And the worst is that slowmotion with optical flow are not taken into account. I mean I got my slowmo but no smoothly, very jerky... so it does not worth it.

If any of you have ideas, that would be much appreciated.

Thanks
