Hi @michaelni, for me I had to change --latex-engine=xelatex to --pdf-engine=pdflatex else I would get

--latex-engine has been removed.  Use --pdf-engine instead.
Try pandoc --help for more information.

but I'm on pandoc 2.1.1. I changed it back so as not to conflate the issues in a single PR, but I suggest we consider updating the pandoc dependency to a more modern version.

The PR is updated for pandoc 1.19 for a re-review.

I added one more commit to split the title and use "FFV1 Lossless Video Format Version 0, 1, and 3" and "FFV1 Lossless Video Format Version 4" rather than "FF Video Codec 1". IMHO "FF Video Codec 1" is an unfamiliar term and using FFV1 in the title would be better.

I suggest  "FFV1 Video Coding Format Version (...)", like in https://en.wikipedia.org/wiki/AV1

@JeromeMartinez i agree, updated
