Sony F3 RGB 444 module vs Red Scarlet/Epic Raw?

[Graeme Nattress]

The sensor pattern doesn't directly relate to chroma sub-sampling on a codec. The two are different things, and to co-mingle them is misleading. What you need to do is measure the output. If you have a 4:2:2 output codec, you shouldn't be able to measure chroma resolution to be more than half, but it still could measure less, just as luma could very well measure less than full resolution. It's still a 4:2:2 codec though. Similarly, on a 4:4:4 system (like the F35) you could measure less on the resolution than you'd expect even on a 4:4:4 recording.

I don't understand why s-log costs more. It's math is little different from REDLog and ViperLog, or Panalog. I can see why a 4:4:4 output costs more, but in this case it sounds to me like a firmware turn-on rather than a new output block on the camera.

Thanks for that, Graeme.

My understanding is that they are basically selling the S-log functionality as part and parcel of the 4:4:4 functionality. Doesn't make sense to me...as you said, everyone should be able to have it, not just those who want 4:4:4.

Quote from their site:

RGB and S-Log output will be available as a future optional RGB and 3G SDI software upgrade, allowing for a seemless workflow for high-end content creation with HDCAM-SR series products.

They don't say it will cost. But they don't say it'll be free, either.

Let's just wait and see then... it might be a free firmware update, just something they couldn't get finished for launch in Feb. Epic is gonna ship with features missing too, so let's not jump the gun and start assuming things.

Good call.

On facebook the Sony rep said: "444 is available via dual link again in April 2011 price tbc." http://www.facebook.com/topic.php?ui...13&topic=14719

That's all the info we really have for now.

Thanks for that Graeme. I don't want to just be spreading FUD. I knew I had seen price come up at least once in regard to the upgrade.
