  • 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 Overview...

Thanks for the clarification Jim. I'm with Gunleik on this one. I love the look of Magic Motion™ and can't wait to try it. I'm just busting to see some normal old everyday dialogue footage shot this way.

One camera with so many creative options. Incredible!!

Thanks for the update.
As you know, the motion was what first impressed me with HDRx™™, even though it will have to be tested before put into practical use...

Just curious here, but it would be possible to set the X-track with a longer, shutter, too, wouldn't it, if you want additional lowlight performance...

(Yes, I do understand that this doesn't sound very practical, but gee will I try... :-))

So ... You're talking about setting the X Track as the correct exposure and the A Track as under exposed? That way you'd tend to blend more towards the X Track than the A?

Don't yell at me if I have it wrong. Hang on, I'm the grumpy one :blushing:
 
Does that mean you would not expose for the highlights as much as normal; that you could try for some more detail in the shadows because you have protection in the highlights?
Otherwise you risk the greater latitude to be skewed towards the highlights?

You guys can test everything yourselves, but before you get too lost... re-read my post. :-)

And before you get too carried away... the A-track will always be the longer (normal) exposure. You cannot set it up the other way.

OK, I think I finally got-it! The “A” track is the primary exposure track, as if shooting regular well exposed film. The “X” track is selected in portions of 2, 3, 4, 5, and +6 it’s twice to shutter speed to six times depending on the number setting for the “X” track. Both the “A” and “X” tracks are on a single R3D. The camera is using the normal 24 frames per second settings set in the “A” track, only the shutter speed for the “X” track is the one changing values. All the rest of the options are in post-production. Its such a simple concept, but all concepts that are simple at first need to be invented, that’s where the genius comes in.

I have been working in the 3D animation and VFX part of films for over a decade and things like MNMB and MagicMotion belonged to the world of fantasy and wishful thinking.
See, we could do that stuff but cameras couldn't.
So even though our material looked more natural, we couldn't use it because the flow of motion didn't match what was seen on film!

Jim by giving us HDRx you have answered the prayers of many many perfectionists like myself.
Thank you (yet again!)

Christian, I am not familiar with the technology involved but multiple over or under exposures on each frame sounds doable but I believe will be limited to the amount of data the sensor, the storage medium and all the other bits and pieces in between can handle.

But maaaaaaybe for Epic-(M and X) that are 120fps capable that would mean a max of 40fps with one normal (track A), one under (track X) and one 2x under (track X+2). (a total of 3 exposures)
Again, I do not know any of the technical details involved and I speak for myself.

Either way, I am so happy I jumped in on the chance to get an Epic as soon as that was possible!
Thank you Jim (and aaaaall the people that make this magic work)

System is constrained to 2 exposures. Good news is that starting off with 13 stops gives you all you need with a 2nd exposure. The early digital cameras may have needed 3 because the native DR was lacking.

In fact... most people won't use HDRx normally.

Is HDRx available in other (and higher) framerates (other than 24 fps) ?

Would love to shoot "Cold Case ending slo-mo style" scenes in Magic Motion. ^^'

Yes... half of the capability of the normal camera. For EPIC-X/M that means 5K at 48fps (60fps at 2.35:1). Higher for 4K, 3K, etc.

Jim
 
Makes sense.
Like I said in some other thread I think for normal use the capabilities of the sensor will cater for all of our shooting needs.

But...
I got my RED One (and now the Epic-X (or M hopefully) ) because I want to do my own features where not some but almost EVERY shot has some sort of animation or effects so I think I will be shooting using HDRx™™ most of the time.

Either way, by enabling this feature you have opened the Epic and the Scarlet to a much larger market! Think of the scientific applications on top of all else!

Can't wait to do that!!!!!

EDIT: I know and I hope you are pretty well aware that you are closing in fast on 5:15am... I've been staying up working till 8am every night since 2001 so I am glad I am not alone. :-)
 
I'm just amazed at this, really.

Jim and Co. you've created the Thermos.

How do it know...
 
What about Rocket support? 2 cards for playback? (and 4 for stereo?) maybe one card can handle the two streams in half res?
If both tracks are inside one R3D, I imagine there's only one timecode (and one name of course). Just thinking in future conforms...
 
I never thought I'd say this, but I'm just as excited about Magic Motion as I am about the increase in dynamic range.

With MX and the new color science, I'm generally not feeling particularly constrained by dynamic range. Sure more is better, and they'll be times when it will save a ton of time, or enable a low budget shoot not to have to fight the sun with expensive lights, but more fundamentally, we really don't see motion blur in the traditional sense in the real world.

Obviously I have no practical experience with this yet, so I still have a lot of ignorance, but having seen the HDRx™™ on the big screen at Reducation, I'm already a believer.

When I think about 3D high speed footage of that snowboard run with magic motion turned on, we'll enable people to see in ways that just haven't been possible before.

Pretty cool.

I'm also pretty sure that the Ocula team is having fun figuring some of this out. :-)
 
Wow a camera company that gets it! From a dynamic range, post, and vfx point of view this is more then we could have every hope for! You guys are like the pixar of the camera world; a small group crazy geniuses that have forevery changed everything.

Just keep being you.
 
Is it technically possible to have an one stop mode for HDRx™™?

I could see that being useful, with closer to normal motion blur and with one extra stop of latitude.

Also, in this mode, we could shoot with 360 degree shutter, treat the extra HDRx™™ track as our normal exposure with normal 180 degree motion blur, and treat the base exposure with 360 degree as an extra (which could be i.e. keyed to affect only shadow areas of the image). I could see this being very useful for reducing shadow noise in low light shoots, without losing the feel of normal motion blur altogether.

Oh, and congrats for putting HDRx™™ in the new cameras - it's pretty close to what i suggested two years or so ago - maybe some of my ideas inspired you along the way (wishful thinking, i know) :redface:
