Video is a lot more forgiving when it comes to timing

It can be entirely possible to reliably process 4K RGBA images in 40ms
(25fps) ~900MB/s; while the same machine fails to process 128 audio
samples in under 2ms (~256kB/s).
In general a delay of an extra 40ms frame or two doesn't matter either so
long as the sync lines up. I have watched a number of remote news bits
where the latency is ~1 second or more (which is disturbing BTW). I have
had better long distance phone call latency.
Ya, video and audio are two different animals.
