3K HDR?

[Arnold F.]

Are there samples around of Scarlet 3K HDR? How is the quality at 3K? I might need to do this for an upcoming shoot that will have dark skin on a beach in bright sunlight.

3k Scales up to 4k really well. We delivered a few projects a couple weeks ago in 4k all our slowmo looked great when scaled up to 4k and sharpened

Also make sure you shoot on sharp glass or stop down to where you know it's sharp.

That's great news. What is the strategy? Do you expose your A track for the darker areas of the frame, measure how many stops your highlights are away from that and set the HDR accordingly?

 

[Mike P.]

Yeah, that's about right (expose for A-track -- make the shadows bright enough -- and then capture as many stops over that on the X-track that the motion will allow).

Just remember that at +3 and above, you really start to notice the motion difference between the two tracks. Honestly, with bounce/fill it shouldn't be too much of an issue capturing +2 and then using that to have a smoother/softer roll-off into clip. Realistically, it'll look weird (mapped) if you try to maximize all the DR into a rec709 space.

How does motion enter into it?

How does motion enter into it?

Think of HDRx as a dual-shutter-speed mode where the X-track gets captured with a shorter exposure time, which means you get less motion blur on it.

I noticed that when I read the manual and wondered about it. For a moment I thought perhaps the A track's slower speed would disguise the X track's faster speed but you appear to be saying it doesn't at the extremes?

 

[Paul Schneider]

3K is pretty solid.
2K is usable.
1K is a flip camera.

Don't forget, that using more than +4 (+3 to be safe) stops in HDR leaves you with a "gap" in between track A and track X that looks quite ugly when you're mixing the two tracks togethers. AFAIK, it happens due to the fact that on track A you have your highlights blown, while on track X you get to a point when your A-track mids are already underexposed which leaves you with noisy data in between those tracks (if my explanation makes any sense).
