  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

HDRx footage...

I dont mind an extra cost for the hdr feature on scarlet, but how much would it (a guess) extend the time frame for an realease. Is it possible to build a hdr module instead? Thinking out loud=)
 
That's sort of killing off the point of the video, wouldn't you say? -:)

No not really, The grade Alex did is more in line to what you would have to match other scenes I would think.

The flatness and the DR of this shot gives you a huge range of possibilities.

well done sirs.
 
WOW is an understatement!! REDtastic!!! better suites this footage. I've seen some rubbish HDR footage, but this from RED shows how it should be. Does this mean I can ditch my lighting kit??? huh??!!
 
So will the foundry & autodesk add a "magic motion" motion blur to seamlessly add cg elements into this new kind of footage that will likely be used very often or does the vfx sup need to tell the DOP to take his finger off the HDR modes when shooting for cg integration?
 
The jury is still out on Scarlet and HDR but it just does not have the processing power of an EPIC.

I have to wonder if Scarlet owners would prefer HDR in their cameras if they had to pay extra for it. We could up the processing power by adding boards but that will cost money and I'm not sure if Scarlet buyers will go for it. Some feedback on this would be helpful on another thread in the Scarlet section of reduser. Given the change in development path, board costs, an additional ASIC and "stuff", we are probably looking at an additional $1000 more or less.

If we did this, Scarlet could have both EasyHDR™™™ at 30fps and HDRx™™™ to 60fps.

Just thinking out loud here...

Someone want to start a thread there? It should be good for a lively debate.

HDR Scarlet S35 for $1000 more? count me in!

ups sorry didn´t see somebody had a thread for this in the scarlet directory already. ->> http://reduser.net/forum/showthread.php?t=49942&page=9

HDRx™™ + a 4K 16bit post production pipeline is going to give a incredible moving images - and control over those images.
...

Forget 16-bit and/or EXR. Let's keep it RAW from start to finish - just like Aperture (Lightroom) does for RAW stills...

EPIC / RED ONE M-X / Scarlet + STORM + RED Rocket = my personal dream! The best part is that we already have the yellow part to an extent...

:devil: Peter
 
WOW! That is just freakin' awesome! The image reminds me of some of Reid Miles' advertising work he shot on 10x8 Vericolor back in the '70's. (sorry, can't find any pix online) The new motion is just poetic - I think even more incredible than the HDR - or at least as important as.

I second the question regarding building FX shots to match this. I want to shoot everything this way. Please release the Scarlet with this or as an option a la the MX upgrade. I'd hate to drag this torture on any longer.

To me this would only make sense if it was a separate model to the existing one announced. In any case I have started thread and poll at the SCARLETUSER:

Jim or Jarred, can you share what sticks and head you were using for this? just curious what you were using running up and down the vegas strip =). A few bts shots of your setup would be cool to see if you have any. Back to HDR.. man I can't get over the possibilities. motion image capture will NEVER be the same.

Before anything else : congrats, no other camera can do that!

1/48th (180 degree) shutter
REDCODE 50 (just over 5:1 compression)
5ms read-reset.

Let me tell you what I see when looking at two subsequent frames during the fast pan. The light bulbs are like comets with the head in the direction of the pan, except that they move inverse, tail first. The tails may be as big as the gaps between the tails without the heads, but head and tail together are larger than the gap with respect to the next frame.

So what I conclude from what you wrote/write and what I see is this :


- Magic HDR starts by taking a short exposure for the highlights and read is followed by reset for a second exposure without any break, the longer exposure for the shadows. The break (line readout + reset) is short enough that the combined parts (the overlapping DR of the two exposures), combined as a weighted sum, shows no noticible gap in the motion blurr.
- for this to work, I suppose that the MX can reset lines independently of reading them out and can read a line while resetting another line so as to allow exposures shorter than 5ms (otherwise, HDR could not gain more than 2 stops).

Please don't just answer (as often to such posts) with "wrong ;-)", since now you show us something and everybody can see the specific artefacts of the mode. You can just improve our understanding.

As for the highlights, unavoidably they might saturate during the longer exposure, also on the parts that are not exposed by a highlight on the shorter exposure (moving highlights). As a result, the « comet tails » have no usable information with respect to the saturated color channels on either of the two exposures. This would be an unavoidable artefact (the one thing you might consider « unnatural » in your footage) of the fact that the two exposures do not take place at the same time. But there could be a clever ways of dealing with this artefact, since it is possible to identify these zones quite precicely : they are saturated in the longer exposure and too dark in the shorter exposure to justify that saturation.

Wiith respect to the highlights, they remind of first curtain flash exposure.

In the parts where the two exposures are combined, the exposure time seems to exceed 1/48s.


Suggestions (even though you might have thought about these already, but consider it feature request feedback) :

* you might include in your options the inversion of the exposure order (like "second curtain highlights") and that may look more natural. Most photographers prefer second curtain for flash with motion anyways.

* you might also propose to set the exposure time as a combined time and not just for the lower lights.

As to the Scarlet HDR question : are you talking S35 or 2/3"? For 2/3", I think that pricing is more important than HDR. As for S35, a feature set somewhere in between your current announcement and EPIC can of course be very interesting.
 
I would gladly pay much more for HDR on the SCARLET.
 
Thanks Jim! I feel like I've witnessed something historical. When I read about HDR and mentioned it to my wife her first comment was how cool black and white would look. I felt very proud since she's not a camera person. Red just makes everything better!

Thanks again!
