Yes, and every frame/slice has an embedded checksum if you use FFV1 version
3. This is particularly useful in an archival context, but even more so if
you capture directly to FFV1. You have checksums at the moment of the
creation. And there's a really active community of users as well.
The open license has led to a lot of creativity and a startling amount of
custom capture tools have been created around the codec, such as vrecord,
DVA-Profession, and two tools that were created via a large scale project
in University of Indiana: https://mdpi.iu.edu/doc/MDPIwhitepaper.pdf
We just use a v210 capture ->FFv1 ffmpeg transcode with losslessness
verification via framemd5 though.
