ProRes 4444 vs. AJA Uncompressed 8 bit
on Oct 29, 2009 at 2:00:05 am

I just upgraded to FCP 7 + AJA 6.5 -- in the middle of a job, not my idea -- and had a surprisingly pleasant ProRes 4444 experience.

The footage was provided to me on an external drive -- which I copied to my array, where it behaved very well.

My question is, next time I digitize, for any given format, should I use the AJA KONA 3 ProRes 4444 setting or the AJA KONA 3 8- or 10-bit setting?

The ProRes files were smaller in disc size and comparable in quality.

I create movie trailers, tv spots, etc. -- never anything over 3 minutes.

Just ask my wife.

Seriously, what's the short answer?

the short answer -
most people continue to work with ProRes422HQ, which NO ONE rejects.
ProRes4444 is even better.

And what is uncompressed video exactly ? :)

Next to my refrigerator, I have a D1 deck.
I archive everything to D1.
It's basically preparation for the end of the world.

Honestly though, I know exactly what 4:4:4 is. What is 4444?
Am I color blind?

ProRes 4444 (pronounced 4x4) is the new high end Apple codec that ships with FCP 7.0.

When you update to AJA Kona 6.5, the playback and capture options now give you not only the 10-bit and 8-bit Kona compression settings for the different frame rates, they also directly support the ProRes 422, 422LT, etc.

So when I digitize, should I choose the pure Kona codec for a particular format, or the Kona ProRes 4444 if I want the highest quality?

[Chad Brewer] "Am I color blind? "

ummm...
we cannot answer that

However if your male there is something like a 1 in 4 chance you have some degree of color blindness with a full 7%-10% of ALL men in North America being completely deficient in the Red/Green part of the color spectrum while women only show a 0.4% rate in the same demographic.


"I know exactly what 4:4:4 is. What is 4444? "
RGB with Alpha - ProRes alpha is up to 16 bit. (65,536 levels of grey)

and I am betting you can't see that many levels of grey either.

Gary,
Thank you for including the answer to my question in your unnecessary smart ass response:

"RGB with Alpha - ProRes alpha is up to 16 bit. (65,536 levels of grey)"

Bob,
I've read many of your posts and responded to some of them. I enjoy your humor and appreciate your experience in the field.

I look forward to future punishment in this forum.

Since you fellas seem more interested in flogging each other than in answering my original post -- I'm gonna look elsewhere for some expertise re: the best codec to use.

ProRes was designed as a intermediate codec to offer users highest quality while offering moderately compressed content.

YOU want an answer that no one else can give you. If ProRes works for you then Use it.

ProRes is Always 10bit - 8 Bit UC is always 8bit.
Do you want to use lots of disk space and never be able to do anything in real time use 10bit UC.
