So i'm trying to work with sony a7siii footage shot at 4k 100fps 422. It's a bit heavy for my PC so i have proxied all the footage. It seems to work well when i start working on the project although as soon as i reopen the project another time / adjust aspect ratio / clear rebuild previews / other things you would think you can do without problem, the proxies seem to desync. The proxies either playback at 4 times the speed or freeze on a single frame during playback.
I have tried creatinng a plethora of different proxies which is extremely time consuming. The same issue arrives everytime.
I don't want to interpret the footage to 25fps because i want the clip to playback at normal speed when i add t to the timeline, not have to readjust from 4 times slow moton.
The only time it seems to work alright is when i create hvec/h265 100fps at super low spec. It works fine for a little while and then the preview window randomly goes black and i have to either restart premiere or restart my pc and fire up the project again.
I have searched and search across all the interweb for someone with a similar problem and have found naught. so wondering if any of you could help.
Asus Zenbook Pro Duo High Spec late 2019
32GB ram 2667
RTX 2060 MaxQ
Gopro Cineform matched framrate (Which creates 60fps for some reason) 1mbps 1280x720
Gopro Cineform 50fps/25fps 1mbps 1280 x 720
Hvec/.h265 100fps/50fps/25fps 1mbps 1280x720
And a few others i can't remember.
I have also reinstalled every version of premiere from 14.4 - 14.9
I have used the adobe tool to clean and reinstall all adobe software multiple times.
I have spoken to adobe support on chat and on the phone many times over the past couple of weeks and they just keep asking me to clean reinstall different versions of premiere each time.
My work around at the moment:
Guess how it's going to look in the sequence > export > see how it looks > adjust and repeat.... i can't work like this!

I believe you should use same 100fps proxies for normal (not slo-mo) clips. And whatever needed fps for slo-mo parts (assuming you doing latter via 'interpret footage'). If AME do not allow 100fps, try this tool: proxy generator
I'm trying at all costs to avoid "interpret footage". I run and gun so easier to to shoot everything at 100fps therefore it's better for me to have all clips play at normal speed whether it be in preview window or timeline. I don't want to speed it up to 400% for normal.
I can create 100fps proxies in .h265 but it's causing stability issues with premiere so not ideal.
.h264 proxies = dsync/freeze frame/ sped up on play back
.h265 proxies = premiere crashes/random blackscreen in preview window*/unstable playback (sometimes plays back smooth, sometimes really choppy)
*switching renderer from CUDA to OpenCL seems to have fixed this but will see... like i said, random
Have you tried creating your own proxy settings? You can do so with AME by creating a Encoding preset first, and then an Ingest preset based on it. I suspect there is something happening with the FPS settings, so you might want to keep it as Match Source
