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.
