Veai_fi inputs

This page provides an overview of the command line, but there was no example of the inputs for the interpolation filter, I.E. veai_fi.

I guessed my way into this:
veai_fi=model=chf-3:fps=60

That works, but I noticed a message in the log, making me wonder if there is other syntax to specify the input framerate?
[veai_fi @ 000001BB0E3B5C40] Unable to parse option value “0” as video rate

Thanks for your input on this.

For anyone wondering, the latest syntax would be: “tvai_fi=model=chf-3:fps=60”

You can stack filters so you can upscale and interpolate at the same time with “-filter_complex”. For example:

ffmpeg -hide_banner -nostdin -y -strict 2 -hwaccel auto -i "CLIP_2.avi" -pix_fmt yuv420p -filter_complex "tvai_up=model=iris-2:scale=2,tvai_fi=model=chf-3:fps=30" "CLIP_2.mp4
