JPEG vs Pro-Res

[Jim Brennan]

Sorry for the newb question. I noticed that when you output from REDCine as a QT file, it defaults to a JPEG. What's the difference between that and pro-res?

Still fumbling through all this. Sorry.

And, if I might add another newb question, if I know that I will be delivering on SD DVD, does it make sense to output in DV/DVCPRO as opposed to ProRes?

you are exporting the highest quality possible because you want to grade your stuff and you dont want that your picture falls apart...

As far I know Prores and output of Redcine QT is based on JPEG2000. Am I wrong?

I always export in ProRes for SD DVD masters. It's better to have a high-quality file with minimal color information loss to start with, even if your video is going to be downscaled to 480.

Depending on your overall needs, you might also want to look into using a Crimson workflow. It'll allow you to do color grading and such after an offline edit. Then, you can round-trip it back into Final Cut for export. To me, this is the greatest advantage of RED's workflow.

standaard jpeg is 8bit,
prores HQ is 10bit, thus better for colorgrading and mastering.
Still you could choose photojpeg as mastering output at 75% quality = 4.2.2, as it is a nice compressed i-frame codec that is multiplatform. all quicktime versions will play it. ProRes is Apple only.
For final delivery, not for editing or recompressing , you can use H264 at the right settings and compression rates.

Both are based on Wavelet compression, but one is not based on the other.

Thaks. I am looking into Crimson, but I am still a little out of my element with an offline edit. Soon!
