  • 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 Magic Motion

Have you tested yet with under cranked shots and longer than normal (24p) motion blur?

eg I want my actors to look like they are fighting with super human speed so I shoot at
18 fps s1/36
 
What about a situation where flashes are going off, both synced and non synced?

Or what about zooming?

Looking forward to using this for sure!
 
As I have been looking a bit into this on different cameras lately, that is exactly what made so enthusiastic about the Vegas, and now this clip...

I hope magic-motions works with easy HDR, too...

Apparently it does...

2nd time posting this...

EasyHDR™™™™- done in camera with "Magic Motion" only.

HDRx™™™™- done in post from two streams. Either "Magic Motion", MNMB (More Normal Motion Blur), or ignore 2nd stream for "Normal".

Jim
 
Sorry, maybe the answer is somewhere... But can HDRx™™ Magic Motion could be apply to simulate mechanical shutter feeling ? Like no strobing on vertical lines during pan!

Because Epic will beat 35mm camera right away if it does...
 
Can't wait to see this used in some form of action/stunt/martial arts application. It's such an uncanny thing to watch. Between the motion and the gradability of the stream - feels like an entirely new aesthetic has been created.

Yeah. Hopefully this new aesthetic won't include handheld fast-cut shaky-cam camera movement where you can't see what's going on. I want to see more fast but smooth pans / camera moves and a couple speed ramps where you can clearly see what's going on.
 
W3e can do better than that. If you drop the "x" frame stream... you have normal motion.

Jim

I think you guys are giving 3 great things in 1! The HDR capability, the Magic Motion capability, and dropping the "x" frame stream you can get a normal motion image... that's so nice!

So I'm thinking out loud. You could shoot in the HDRx mode to have those extra stops and in post just get the parts of the image you want to use from the "x" frame stream, mask those zones and doing a composite if you want the normal motion blur and the extra stops needed for a window for example, wouldn't you?

Anyway, just waiting to see the MNMB you are working in with the Foundry guys. Not that I dislike the Magic Motion, just noticing all the options you are giving us! Greaaaaaaaat! So many new filmmaking options in one little camera!:emote_head_explode:
 
Dying to see 3D tests - should work fine assuming the shutters are sync'd during HDRx™™ capture.

Same here. Also raises another question - Jim, how are the sensor syncing issues on the current state of the epic/scarlet platform? - and if any remain do you see any big problem in getting them solved?
 
I love the SpinWeb sample footage.........Thanks!

However, I thought that the added tone mapped DR was only in the highlights.
This SpinWeb sample does not seem to have any bright highlights....so did you
have to expose the shot until the spinning pole was in the top 3 stops?
I hope what I am asking makes sense? The Vegas HDRx sample had obvious highlights,
whereas this spinning test does not. So I only expect the higher shutter speed to be
visible in highlights.

Oh!..........Thanks to your "persistence of vision" Jim.
 
The amount of added dynamic range (and "Magic Motion") is numbered by stops... +3, +4, +5 & +6.

You select. The higher the number, the sharper the "other" stream is...

I am set on +3. But I can see times when I would select higher.

Jim

Since this is utilizing the "other" stream, is this something that could be adjusted in post? Sorry if that is a dumb question but being able to control the inherent "sharpness" of motion-blur in post (while not really necessary) would be very interesting.

And just to be 100% clear, this effect is not achieved by crossing the streams is it? Is RED ready to take responsibility for the unknowns that brings into the equation? ;)
 
I would be curious to know how Magic Motion affects rolling shutter artifacts (horizontal tearing) from flashing lights like muzzle flash, fireworks and lightning.

...how are the sensor syncing ..on the current ...epic/scarlet platform?

We have done extensive 3D tests on EPIC Michael; it's rock solid. Even better than on RED ONE.
 
I have a couple doubts, from a Post/VFX/CGI point of view.

Many years have been spent trying to get accurate simulations of motion blur and related visual artifacts. Does this new way of seeing motion affect us compositors/vfx guys?

I keep looking at the Vegas shot of the fire truck, and keep thinking that if had to do some kind of work on that shot it would be a nightmare matching the look. Not only that, the look would change depending on the settings that they put on the camera.

I know a solution... work both streams independently and then remix em.. yeah, right... double the work, and for sure not double the pay (and who can guarantee we get the tools for a proper mix of streams?).

Thats just for comping, lets not even get started with 3D (as in CGI).

Or how about a stereo show with cgi + HDRx + Stereo? Does this imply 4 streams of footage????

You can see where I am going with this...

I did joke about this in another thread as it is something that will need to be overcome. I'm sure I could write an expression to mimic the motion blur characteristics enough for it not to be noticed.

Will have a play...

You could write a camera/lens shader which simulates magic motion pretty easily. Just weight the motion rays to the initial tick and then sample as normal from there.

But yeah... it's going to be a pain in the ass to match in general. I suspect initially magic motion will be off limits to fx plates if possible until everyone gets their 3D pipeline straightened out.

We're using RSMB though for 90% of our motion blur so all the shots with post blur will be manageable.
 
There should be no problems with that kind of thing. This isn't a plug in. It's not drawing these "artefacts". It's simply capturing the light as it hits the sensor at two different shutter speeds and combining them into one image. If it doesn't move, it won't change.

I love it. I think it's one of the most exciting things the Red team have hatched during this process. I can see every possibility of shooting entire projects this way (HDRx™™), just for the Magic Motion™.

No it's not 2 different shutter speeds combined to one image, just look at a still frame (hint: highlights have the same motionblur as the darker parts)

Nope it's two different exposure lengths.

The "normal" exposure is the full 180* shutter etc. The HDRx channel is motion blur free. The HDRx appears to be an early read-out of the normal exposure.
