I am having an issue when running Nyx. I am trying to render a couple of seconds of video and Nyx crashes 100% of the time. I have tried all other models and they work fine, just Nyx seems to be the issue.
I generated the source file using Handbrake with metadata as follows
180MB size
MPG H265 (I also tried rendering H264, same issue occurs)
640x480
29.970030 FPS
aac 128bit Audio
Behaviour
I have also tried using generating the source as MPG H264 with the same issue. Please note the source files are good, they work perfectly in any video player.
I create a new project in Topaz Video AI.
I add the above source file to the project.
In Topaz Video AI UI, I enable enhancement.
I set Nyx as model
I setup a few seconds of in / out timeline.
I click āRender In / Outā.
I get the āProcessingā label, and then the process errors (see screenshot).
I have tried tweaking the Preferences, Max Memory etc. Nothing makes any difference.
System
i5-13500
32GB DDR5 Ram
NVidia Quardo P2000 GPU
Windows 10
Topaz Video AI 6.2.0
All systems and drivers up to date
Maybe 632x480 is a problem for NYX, or the selected segement is to short. What happens if you select no segment do the full video? What output format was selected? Try h264.
Personally would drag the source into Virtualdub, select filters ā resize and resize 632 to 640 by keeping aspect ratio, then select additional filter āNull Transformā and crop the few pixels away you get vertical size of 480.
Iāve tried various segment lengths, Iāve also tried rendering the full video. Same issue occurs. If 632x480 is a problem for NYX, and it crashes as it does, Iād call that brittle and unstable. Why should the resolution matter? Surely the model is not just limited to a handful of common dimensions. Even a decent error message explaining that as an issue would be bette than just a crash. The output format was H264.
On looking at source video meta data in VLC, it states that Video Resolution is 632x480, and Buffer Dimension is 640x480. Iām confused by this. Whats the actual resolution?
I donāt know what this in VLC means, you can check source file with MediaInfo I donāt know if 632 is the problem NYX does not work, but it is not codec friendly (and not 4:3) ā¦normally this should work also, but not for sure, in fact it does not work and we donāt know why, so try out is the key.
I just recommend do anyway 640x480 native pixel without DAR by resize/crop and export as AVI, then give TVAI this for a try. As I described above, without Handbrake.
What I see in the log is source error āmoov atom not foundā which indicates file is incomplete, corrupted, or not properly formatted. But Iām not from Topaz and canāt interpert their logs well.
Logs are showing that the GPU is running into an error when trying to run the heavier Nyx model. The Quadro P2000 card is below spec for version 6.2 and I see that you have lowered the max memory to 60% it looks like.
Try raising that back up to 75% and see if that gives it a little more room to run.
You mentioned the drivers were up to date, are you running the Studio Drivers for this card?
Kyle, point taken regarding the Quadro P2000. Iām wondering would the CPU (i5-13500) be as good or even better? When I can afford it, I will look at sourcing a used 4060 or something. The price of hardware is insane atm. In the meantime, Iād dearly love if the application could be a little more informative when it comes to errors rather than just pointing us to here and generating a log archive. Iād love to actually know what the error is here? Anyway, Iām grateful for the inputs and responses and hereās hoping for a reolution. Do the logs give you any specific error?
