I think they are talking about Xbow's sprite record at some point, their numbers are off but the interviewer mention sprite crunching in a way :)

I think if there's any questions left about VICII inner workings Albert is aproachable now ? He even showed up in some American c= retro events.

He also mentioned badlines (although not that word).

It would be interesting to update him with recent VIC-II advancements 😅 The father should be aware of what his child became.

Seems like he was aware of the possibility of sprite multiplexing at the design stage.

aware? I'm sure that was intentional. not that it needs anything extra on the chip, but the way it works makes it possible.

Another video with Bil Herd and Albert Charpentier, from Vintage Computer Festival East 2022 in late April:
https://www.youtube.com/watch?v=FwYb1sXqylI
(There's some discussion about the internal clock speed of the VIC-II at 41:15.)

And here's part 1 and 2 of a "panel discussion" at the same event, featuring other Commodore engineers as well:
