Compression Artifacts

[Daniell Simmons]

Hi all,

I just got back from a helicopter shoot with a Red in Africa. I've been looking at the footage for a week now, and although it looks great, I've been noticing some pretty severe compression artifacts

Have you done a tiff export to make sure it's just not how RedCine displays the footage? Someone earlier today said there wasn't as much noise after they exported the footage from it. What about RedAlert?

I would second an export, at first, when I played with Jim's dragster clips, I wasn't too hot on how they looked, but it was just a viewing setting.

Yes, have exported tiff, .exr and dpx and get the same results each time. Admittedly, it's been done with the same video card (NVIDIA Quaddro FX 4400). Would a different card give better results?

No this is an issue that is being addressed. Try the latest firmware (Build 11) it improves the problem a bit, but it still needs more optimization.

[Rick Darge]

It's amazing to know that this stuff will keep getting better.

It's blowing my mind right now..

REDCode might improve with time, but I'm sorry to say the footage you've shot right now is what it is. That looks like too low of bitrate wavelet compression and once that data has been discarded it's gone.

also remember we are shooting moving images, these issues and artifacts are not present at 24 fps on a 30' screen.

have you ever put a feature film that has played more than a day at a multiplex through a simple magnifying glass...you want to see artifacts, dusts, cuts, scratches...

i know it is a not the best answer, but when you look at the options for watching this stuff, it will never be seen like you are dissecting it.

i have done digital projection screening with 2k and 4k projectors for 4 years for all the major studios, distributors and festivals and this footage we are shooting now is unlike anything that has come before it.

again, yeah it might look a bit compressed when blown up in a still image, but that is not how it will be seen by the audience & it is compressed.

That may be true, but these days, not everyone is going to shoot and go straight to projection with no digital adjustment of the image.
