Re: [Avid-L2] DPX via AMA

Been using Dpx workflow on flame rooms for over a decade, raw .rgb sgi files before that.

Dpx has a lot of advantages in vfx world - no gamma shifts being the most obvious. Codecs on the whole worry me, abvb, avr70, motionjegA, microcosm various black magic, matrix, aja have all been and gone while I've been using uncompressed image sequences.

If hate to archive into some compressed format. It's painful though especially when doing a stereo movie and I can't wait to see 4k reduce the storage capacities of every post house back to 90s durations.

It does make sense to use DPX, when you have shot some kind of uncompressed form.

But there is still a file amount limit per folder in most OS's (some 25000 on my box, about 16 minutes.)

And, it's huge. So it's good for inbetweens, before the final assembly.

Now for your stated situation:

Quicktime can be edited quite easilly. I recently made something that does exactly what you described,

insert a new piece in an existing QT.

(like a lineair 2 machine setup, pick source, pick target, based on TC the new clip gets spliced in, either save the original, or flatten (just copy to a new file)

DPX for archiving makes no sense, it's way too big, and hard to play back.

QT for archiving seems a bad idea also, since it's propiatary...

But the whole archiving discussion is something else, and i don't see what AMA link to DPX has to do with archiving...

Still makes sense Jeff. Get a bad render lose one frame and reexport... Quicktime? Yeah let me just reexport the whole 90 minutes.

But yeah 172,000 files gets a bit annoying.
