RS422 HQ vs. Uncompressed
Hi.
I’m going to be editing a standard definition documentary project that was shot in Beta SP. (Remember those really big tapes?) I’m considering using the RS 422 HQ codec instead of the Uncompressed 8-bit codec. To my eye, I can’t really see the difference. I’d love to hear what other people think of that plan.
I’ve got a 2.3 ghz Dual Processor G5 with a Blackmagic Extreme HD card.
Thanks

It’s a great plan. ProRes will be smaller, render faster, is more friendly with RT Extreme, and looks the same… Can’t see a downside myself.

ProRes compression is similar to the compression found on Digibeta tapes (something I never hear people worry about). So yes, it’s totally fine.

RS 422 is a serial communications protocol.
Perhaps you mean ProRes 422 codec?

Yes, I meant Pro Res. Sorry about that.

…good choice, but no need to go HQ for SD-resolution, SQ will do also for SD-work.
We switched a couple of weeks ago completly to ProRes for SD-editing. Since then we edited 4 TV-Shows shot on digi-beta with ProRes SQ settings.
No one can tell the differnce between 8-bit uncompressed SD and ProRes.But you have the advantage of 4 times less space+bandwith needed on your raids.
therefore editing in ProRes feels much more speedy, even on a G5.
The 10bit codec gives you even a better picture quality, especially if you do a lot of effects & grafics.
