No more rawvideo export in pipeline?

(Repost from Topaz 1.6 thread)

Topaz removed the ability to export rawvideo format to pipeline?

ffmpeg.exe [options] | “C:\Program Files\Topaz Labs LLC\Topaz Video\ffmpeg.exe” -report -hide_banner -i pipe: -filter_threads 1 -vf “tvai_up=model=prob-4:scale=0:preblur=0:noise=-0.9:details=0:halo=0:blur=0.25:compression=0:estimate=8:blend=0.2:device=-1:vram=1:instances=1” “-c:v” “rawvideo” “-f” “nut” - | ffmpeg.exe [options]

it gives me an error:

If I replace:

“-c:v” “rawvideo”
with

“-c:v” “ffv1”
it works.

But it makes no sense to compress the data in a pipeline.

Looking into this now and sharing with the devs. Possibly some changes broke part of this workflow, and they will look into this for a patch update.
