[Jonny Hal] "My question is, next time I digitize, for any given format, should I use the AJA KONA 3 ProRes 4444 setting or the AJA KONA 3 8- or 10-bit setting? "
ProRes was designed as a intermediate codec to offer users highest quality while offering moderately compressed content.
YOU want an answer that no one else can give you. If ProRes works for you then Use it.
ProRes is Always 10bit - 8 Bit UC is always 8bit.
Do you want to use lots of disk space and never be able to do anything in real time use 10bit UC.
