do you record uncompressed hdmi output video signal (which bring HUGE gb/hr video file) from the event/wedding??
how long do it take to encode it into DVD? i cant dare to imagine cuz it's already taking me too much time to encode it. and i only recorded it at high-compression 1080p 30fps from 5d3? I believe that's 25mbps.
With the Hyperdeck you can record full uncompressed but it is like a 1.5TB drive for just two hours of footage or something 
.
They also have compressed modes (rates up to 220mbps).
~1.5tb for 2hrs??? so, What is the "real usage" of uncompressed HDMI?
Uncompressed imo isn't very useful. You don't need that much data for 99.9% of jobs.
On the other hand being able to go from recording h264 encoded QTs which are 8 bit 4:2:0 at 90mb/s (all-i) to DNxHD/ProRes (ie the native codecs used by Avid/FCP) 10 bit 4:2:2 at 220mb/s means you're retaining far more colour information within your image, definitely meaning that you have a lot more leeway to perform deep grades on your footage. It'll be interesting to see what a 10 bit HDMI out image from the 5dmiii looks like given the various criticisms the h264 footage has seen - we'll find out if some of the apparent lack of resolution is a codec issue.
Working directly in DNxHD/ProRes is also a big workflow improvement, and means you can have more RT video tracks and RT effects on fast computers, and means no more having to transcode your footage before editing on slower machines.
