I have never used AIC, and I don’t understand why you are including H264 as an option for workflow, as it is a delivery codec. Basically, HDY is a great capture format, but lousy for editing, because of it’s GOP structure among other things.
ProRes is compressed, but you can’t tell by looking at it, and it is one of the leading working formats in use, rivaling 10 bit uncompressed in quality.
I don’t know anyone in here who uses AIC, and doubt may are still using native HDV, with the introduction of PreRes.
There are two excellent papers in here on ProRes by Tim Wilson, suggest you read.
Have a wonderful day.
