Here’s the post I meant to make back when TVAI first came out. (But with the latest version since it’s still an issue.)
With a DVD source in VEAI, I select FHD output and Artemis HQ as the model.
Same input, same output in TVAI. This is how they look:
Left VEAI. Right TVAI.
Now I take that same video in VEAI and up it to 4K then down it back to FHD:
Now I take the the command generated by TVAI for the FHD version,
"G:\Program Files\Topaz Labs LLC\Topaz Video AI\ffmpeg.exe" -hide_banner -i "E:/Dump/HOGANS_HEROES_D1/A2_t01 ff.mkv" -sws_flags spline+accurate_rnd+full_chroma_int -color_trc 2 -colorspace 2 -color_primaries 2 -filter_complex scale=w=640:h=480,setsar=1,tvai_up=model=ahq-12:scale=0:w=1920:h=1080:device=0:vram=1:instances=1,scale=w=1920:h=1080:flags=lanczos:threads=0:force_original_aspect_ratio=decrease,pad=1920:1080:-1:-1:color=black -c:v png -pix_fmt rgb24 -start_number 0 "E:\Dump/A2_t01 ff_ahq12/%06d.png"
and I change the scale to 2.25. It’s the first scale after tvai_up. Above it’s 0. Below it’s 2.25.

Now here’s the result:
I have tried to change the scale in the command on other models. Some work. Some do not.
Here’s the files. Enjoy.
