Hi, new to the board,

I have a project that im working on thats being transfered from 35mm in about 30 to 60 days.

From what I think i understand is that my copy of adobe Premiere Pro isnt going to be able to do anything with digibeta, so i'm prepared to get a copy of Avid for editing. Im going to be with the digibeta deck for 1 week and ill have an SDI card to connect from my computer to the deck.

The questions; how does editing on digibeta work? with systems like premiere, the files are small enough to fit on the hard drive while you edit, and then 'layed back' to whatever i want it to be on.

When i run avid will it store the uncommpressed video to the computer drive and then layback? This is one of the most improtant questions for me. I am tasked with adding effects in another program and then inserting it into the scene. Will i be able to work with the files without comprssing them below the digibeta quality?

If my computer is to handle these uncompressed files which are probably in the high gig range, what type of system should i build to run avid on?

Sorry about the ignorance, thank you for the replys in advance.

It doesnt matter too much if you edit with AVID or Premiere, because you will digitize according to what each of those programs would want. As long as your SDI card works with premiere you should be fine, what you need to be concerned with is if your computer can digitize uncompressed, your drives have to handle something around 40 MB a second, if they can't then you need a more expensive drive solution, or you have to edit at a lower resolution. As for the digitization you need to decide on an uncompressed codec that will work for you, AVIDs is built in, but your card should have its own also.

I would edit 3:1 and the reencode uncompressed when you are done.

so if i understand correctly, some form of compression during initial edit is common even for professional level digibeta editing.

that would depend on system, amount of footage and amount of storage. i'm not sure why your asking editorial questions on a cinematography forum. you are the editor right? also why are you didging to digibeta? what is the end result? what sort of TK are you doing? all these questions need to be addressed, then work out what compression you need.

Hi
I think, you need answer on base question, What format of output movie you must have.
If you know final format you can choose better technology of digital postproduction for you.

If you need 35 mm positive copy for cinema show you can use "film-digital- film" technology.
You need transfer 35 mm negative by 2k ( 4k) scanner to Dpx ( or OpenEXR or some ) files, edit on computer and print positive copy from digital film on Laser Printer.

If you need final movie on video format, digibeta, you can transfer 35 mm negative to video format ( telcine) and edit on computer.

Yes, of course, you can use Dpx files from 2K or 4 K scanner, edit on computer and transfer to video format.
But, this can be a some over spare quality of input image.
