Need some help. Hitfilm Express + RTX 3090 issues
First of all, since around October 2020 that I am using Hitfilm Express, is a great tool and easy to use but I am running into issues that I could not find answers searching on google.
Let me tell you my specs:
CPU: i9-10900k 5.1 Ghz, GPU: RTX 3090, SSDs: Samsung 970 EVO 1TB and 860 EVO 2TB, RAM: 32 GB DDR4 @ 3600mhz, OS: Windows 10 Home.
I have a few issues so let me start with the first one.
Issue #1) The 'Viewer' tab. I work with mp4 4K footage for my youtube channel, mostly gaming footage (4K at 60 fps), footage is recorded by nvidia shadowplay or streamlabs obs.
The viewer tab, lags, get stuck, doesn't play correctly most of the times. Some time is impossible to preview footage properly. This is very weird because I have a lot of free resources on my PC and still the viewer lags/stutter etc. Even worst when I add transitional effects. Footage from streamlabs obs, that are smaller in size and bit rate comparing to shadowplay, are even worst to preview in the viewer tab.
Issue #2) I love doing composite shots and create customized stuff/effects, but when I have composite shots and I want to export to .mp4 4K 60 fps, hitfilm stops the export after 1 min with an error message about OpenGL and running out of memory? The RTX 3090 have 24GB of VRAM and my system got 32 GB of DDR4, and when hitfilm is exporting and I monitor resource usage, hitfilm express is NOT using the 24GB of VRAM, so I don't understand how is running out of memory. This error ONLY occurs when I have composite shots, doesn't matter what type, sometimes having just a composite shot for text just cause the issue. I have to restart the export about 3 times, and then it works fine...
Issue #3) Because I think issue number 1 and 2 are related to resources, why is Hitfilm express not using all the resources available? What is stopping the program to use more VRAM for example, or more RAM. I only see CPU having some spikes to 100% very rarely. Is there some setting/setup that I am missing here to allow Hitfilm express to utilize better the resources? All export and projects are saved on SSD drivers (Samsung 860 EVO 2TB).
Thank you very much 😀
EDIT: When I monitor I see my GPU is at around 9%~28% most of the times, with occasional spikes to 100% just for a second then back to 9%~28%, I see Hitfilm express only using 3GB of VRAM out of 24GB and 2 GB of RAM.
AH and the error I get now all the time randomly is:
"An OpenGL error occurred when trying to render your project and the application must now exit. Do you want to save your project first?"
I don't even have composite shot on this project, and getting this error all the time.
