Importing JPG sequence

[Erik Pontius]

Correct….it would only work with full length imported up rezzed clips…otherwise it’s going to lose track of where various pieces are and break the link between the clips in the sequence.
However, clips that you didn’t use at all wouldn’t need to be recreated.
Perhaps, you should be looking at a few terabytes of storage.
I’ve had a lot of luck creating 1920×1080 comps in AE, and exporting renders using the Avid DNxHD 145 codec, which imports rather quickly into Avid and looks great..creates smaller files than uncompressed as well.

We’ve covered alot of ground in one day, thanks again,Erik.

Alright- here’s some follow up: Where do I get the DNxHD 145 codec and will it work in XpressProHD? If you think it looks better than
an uncompressed AVI, I’ll take your word for it. I had made a 48 sec. uncompressed AVI that was in a 24fps 1920×1080 comp- the rendered file weighed in at 7GB. Any idea what the size-savings is with the Avid 145 codec? (I’ll look for it and info on avid.com)

You mentioned several terrabytes- I have started to fill my third 400GB drive with images, but I believe these edit systems will need to look for importable files from one “drive”. I think this is what you are driving at.

Back to possible workflows: I am now wondering if rather than first rendering anything and everything in AE (with the 145codec or uncompressed), what if I offline in HDV with wide-stretched Avid sequential jpeg imports, but viewing/editing with the Composer monitor in 4×3 and some kind of 16×9 mask, just to get started. Then, if Automatic Duck allows for it- I will bring my first draft to AE where I hopefully can somehow wind up only importing the sequential Jpegs used in that draft. How does that sound?

If you have Avid Xpress Pro HD on the same system as your AE, you’ll already have the DNxHD 145 codec…actually when working in a HDV project any effects, transitions and other renders on a HDV timeline will be at DNxHD 145 resolution.

if you want to use them on systems that do not have Avid installed…

You are right, the HD 145 codec was available in AE’s QT render options. That same 40sec, 7GB avi rendered as 1.1GB. Import to Avid went from 18mins to 12.

The clip from QT played in an hdv Project without trouble; the Avi-imported clip produced those choppy red marks. I could’nt really see the difference in quality, so I’m interested. Thanks for your input, Erik. I think I can ease up on the follow questions….:)
