Working with very large AVI file
I am using CS6 and restoring a feature film for a client and I will working with a 40GB AVI file.
1. Can he send this to me as one large file or is there a limit (importing etc) what Pro can do and especially with my computers resources? Should I ask him break it down?2. He is the one that will put this out on DVD. Since the file I am going to send it back will be much larger should I send it back in several individual files? How should I encode the file back to him?
Thanks for you help.

1. Sure, you can import it. I had no problem loading 20gig files from an Arri Alexa on my 2007 Macbook Pro. It never tries to load a clip in memory all at once, it just reads what it needs to as you play back, just like any other video player.
Depending on the codec (if it’s heavily compressed… which is silly if you’re trying to restore it in the first place) you may have some limitations with how smoothly it scrubs.
2. That is entirely up to you and your client. If they’re converting for DVD, they should have some grasp on their requested delivery format. If you have the budget for a hard drive, I would do a TIFF sequence with a separate audio track, and send it via mail: UPS, FedEx, etc.
Image sequences take up a lot of space but are easier to manage than a single video file.

A TIFF sequence for DVD authoring sounds pretty overkill because the client would still have to transcode it to mpeg2. If you need to render a file master out of it I’d probably use the dnxhd codec for that and if they only need to make the DVD a DVD-ready mpeg2 file would be smaller to transfer. Ask them what they want.

I was editing from a 47GB .mov file perfectly fine today (SD prores capture of the switched feed from a hockey game). Loaded in the viewer, scrubbed, and played back just as fast as a 10 second clip. Was running from a WD mybook firewire 800 drive.

Well, there’s really no problem if you import a file that big to your premier pro.But make sure you have the appropriate computer unit to perform that.
