This subject came up again while I was at a party/concert thing. Two people I know that are way in to video editing were asking each other questions. The thing they got hung up on was...
"What do I do about AVCHD? I have a Panasonic. I can dumb it down to the lesser Intra format, but I really don't want to. I'll lose quality. I just got the newest Final Cut Pro, and it won't import my footage." - C
"Yeah. I have to convert my video in to a format before I edit. You just run it through a program to do that." - A
"That seems to defeat the purpose. In a way, it's no better than dealing with tapes." - Me
"And my camera isn't crappy. It's 'prosumer' i guess." - C
"AVCHD-Intra was made for the little HD camcorders you find at the department store. It's not bad, but people who use desktop editing software more often than not have a slightly nicer camera that uses AVCHD." - A
All of us sometimes work with smaller camcorders that are AVCHD-Intra, and they're fine when that's all you need. It's just that as soon as we bump up to the nicer cameras we use for making a film (a case where you use decent editing software), it's always in the AVCHD format.
We had all heard of Lightworks (through me), and agreed that AVCHD (not AVCHD-Intra) is the most important missing feature of all the high end video editing software packages. Premiere and FInal Cut had the same problem. I would have loved to refer them back to lightworks, but it's still suffering from only adding Intra so far.
