Unable to Run Theia after 4.0.0

After installing V4, I can no longer process higher-resolution videos using Theia. I did not have issues prior to 4.0.0.

The conversions fail after approximately 10,000 frames with various errors. At higher framerates, the most common error is ‘backend not available’. At lower framerates it’s ‘failed locking bitstream buffer’.

Other forums say that this is an ffmpeg-related problem. I am only using one process. I don’t see any details about Theia in the 4.0.0 release notes, so I assume the problem stems from recent changes that are not directly or specifically related to Theia.

Is someone able to explain how Theia functions on the backend and why it seems to be more delicate than other models? Even when it was working in previous versions, it was always much slower than the other models. Version 4.0.0 is only using 8GB VRAM when Theia is running. I didn’t see anything abnormal in the resource monitor.

What resolution exactly? Maybe I can confirm this bug.

So far, 4320p, 2160p, and 1080p have all failed so HD/UHD. Have not tried 720.

Doing an H.265 1080p video on Theia fidelity PNG output. At 13,000 frames so far. Not crashed.

What framerate and interpolation model are you using? Also, this was with the Detail model, may make a difference.

Standard 23.976 fps. I never run interpolation at the same time. I can try it though to see if it dies. It has made it to 24,000 frames.
I put some values in all of the sliders.

I always do them together. The failures were at 60, 50, and 30 fps. Was never problematic before and no issues on any other models.

Okay running them both now. It will probably work because I changed some things in the command. What output are you using? PNG is very forgiving when it comes to interpolation.

H265/MP4 for 8K and H264/MP4 for everything else

Alrighty. I canceled that last one. I don’t think it was going to fail.
I have very different goals when using TVAI, so I keep going to what I usually do.
For example, I would never upscale to more than 1080p. Nor use the mp4 container. Nor run interpolation at the same time. Nor use an interpolation models that is not Apollo. I have long boring reasons for all.

Here’s my last try, but it’s probably still not as heavy hitting as what you are doing:
1080p source => Apollo 8 no replace duplicates 59.94fps => Theia Detail 3 with like 10 in each of the sliders => 1080p H.265 Dynamic high mp4.
