Hi Thomas,
There are piles of codecs out there right now. However, the most truely universal method is to save the movies out
as DPX frames. These are the most portable, across several platforms. You also have the ability to do filmouts from HD if you wish.
Most DI houses require the DPX format when doing Color Grading. DPX is also uncompressed, so there is no loss of image
quality. The format also supports several types of metadata to be embeded into the file. Some include directors notes,
video signal and video color information, Reel/Take name info, etc.
Other advantages include Timecode support, plugin availability for Photoshop, AfterEffects, Final Cut Pro, Shake, Flame/Inferno etc.,
and sequences that can be broken up across several firewire devices. (DPX saves a frame per file, instead of one big monolithic
file Gigabytes in size.) These files are readable on just about every platform used in production.
The DPX file is typically 8.5 Megs/frame for 1080 sized images. 720p should be 3.7Megs/frame.
Lastly, just about every studio and facility out there knows how to work with DPX files.
It is a widely used format around the world. Generally, you can hand a drive to a facility that you haven’t worked with
before, and they will have no problems reading them.
