I have attempted to upscale an MKV video file multiple times without success. Each time the attempt to upscale the file ends with the unhelpful message: ‘Error’
I am using Topaz Video AI v6.1.3
My graphics processor is an Nvidia RTX 3060 Laptop edition processor
The processing settings are 1 process with 50% max memory
I have attached the logs for support.
Any assistance you can provide would be appreciated.

I’ve had something similar before… TVAI processes the MKV all the way to 99% and then generates an error… But doesnt inform me what and nothing definitive. There was something in the logs that suggests there might be an issue the the metadata in the MKV…
editVideoInput::Video info not found for uid 0
I’ve experience the same issue myself… How I resolve was to re-encode the video with Handbrake, but using the FFV1 codec. FFV1 it is lossless, so you wont be re-compressing and degrading the video any further… Dont change any other spec other than the video codec. Passthrough your audio and subtitles too and save as MKV.
Your MKV will be much bigger, but this on only temporary until you process it through TVAI.
Let us know if this helps and works for you.
As @bbyers-0695 recommended, I suggest you try converting the input clip using Handbrake. Can also try as an mp4 h264 as well, though this will compress a bit.
Often times, there is, in fact, a metadata issue with some mkv files that causes the errors when encoding.
Thanks for the tip. I was able to successfully upscale the video once I converted as instructed using Handbrake. I had to make sure the ‘passthrough common metadata’ box was unchecked before TVAI was successful so whatever metadata is considered ‘common’ must have been part of the issue.
Thanks again for your help and to margaux.topazlabs, who also replied, as well. I’ll be adding Handbrake to my toolset for these contingencies from here on.
