Broadcast Quality

[Paulo Pandolpho]

Hello,

I work in a production company here in Brasil and we´re considering using the RED technology to produce an upcoming TV series.

My question is regarding the Reference QT files that the camera generates. I understand that the H QT is half the size of my original shooting format. The same with the M and P sizes (each half the size of the previous).

I just wanted to understand if the resolution is the only loss I have according to the chosen QT format. In other words: does the QT file contain ALL the information the raw file has (as far as color and visible elements, for eg.), only in a smaller size?

Do any of the generated QT reference files have a broadcast quality?

Thanks so much.

Hope to hear from someone soon.

Best,

Paulo

The QT Proxies are just a link (like an alias) to the original Redcode file. They don't contain anything, they are just asking your machine to do a fast decode on-the-fly. To achieve this, even on a fast machine, they are not using all the tricks Graeme and his team are pulling to get the very best quality out of the RAW files (de-bayering and filtering).

Currently, IMHO the best route for HDTV is shooting full-res (after all, it's 35mm aesthetics for which you buy Red One, are you?) and import through log and transfer in FCP. You can do a first-light in RedAlert and apply that grade while importing into ProRes, that should look very good and is reasonably fast.

Regards,

Uli

Hi nomad, I'm waiting for both my camera and my new Mac/FCP system to arrive and I too will be outputting for 1080P HD. Just to continue the workflow described above: after you import into ProRes you then use that on the FCP timeline?

Also, being new to the Mac/FCP I'm not totally familiar with how the 3 or 4 K RED files get transcoded to ProRes. This is done within the computer using the computer's processor (as opposed to using say a Kona3 card?) I take it the I/O card has nothing to do with the transcode from the RED 3 or 4K files to ProRes?

Is the trans code real time? if not how long to trans code a minute of 4K into ProRes?

Thanks

Hi Sam there is an option in Final Cut, you have to install it, Log and transfer that makes the conversion 4k to 2k 3k to 1.5 etc, I will say quite fast and nice for editing.
The time depends in your computer. Is taking me abot a 3:1, but as said just a reference. It should be around that time in your computer as well.
