Hi,
I’m running into a consistent rendering error when processing a video with a resolution of 852×488 using the Starlight Sharp model with the 3× factor.
logsForSupport.zip (1.9 MB)
The render process repeatedly fails whenever this specific combination is used.
This issue appears to be reproducible and happens every time I try to render a video with arround that resolution and model setting.
As requested, I’m attaching the logs below.
Thanks in advance for any help.
The logs are showing the GPU is being overwhelmed and erroring out when running that upscale factor.
Open the Preferences Panel and make these changes to see if that helps.
File>Preferences>Processing
Ensure that your GPU is selected for the AI Processor
Set the max memory to 80%
Set max processes to 1
Save the settings and close the panel.
Re-run your clip through the process that you were trying.
Thats for your reply!
I’ll give you an update.
An again. It’s happening again at around 1 minute of rendered material. Here the new Log.

Not sure why the forum never sent me a notification about your reply back. Apologies for the delay.
The logs are showing that it is still overloading the available VRAM and erroring out. I would say dropping it to 65% should cover it with that 3x upscale.
The other option would be to do a 2x upscale and then bring the file back in for a second pass with Gaia to the desired output scale and that will reduce the memory needed and should complete for you.
No problem. I was able to resolve the issue in the meantime.
Limiting the usable VRAM to 65% did indeed solve the problem. That resulted in about 23.5 GB of VRAM being used on my GeForce 4090.
However, since I’m now using a 5090 and Starlight Sharp can allocate up to around 31.x GB of VRAM in its configuration, I can now run Topaz with 100% VRAM utilization.
