  • 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 :)

Thanks Jim.

Then we are all waiting for that...

Also would be nice to have some HDRx™™ enabled R3D with a motion that we can see more about possible shutter speed motion blur issues...

Maybe that sort of antique Balinese marionette doll can make some movements and motions...
 
Wow is this fun, though I would have to get down some kind of work flow because I could blow hours tweaking the settings with this. Lots of fun and lots of potential, thanks for putting this up John it is most appreciated.

here is a very rough try...

Thanks again John for this, and as always Jim, Jarred, Greame, Stuart and all the hardworking folks over at RED thank you for this.

have a good one.

John, thank you for sharing the HDR clip, its really cool to play with in RCX. Once 3rd party finishing apps support this, it should be very powerful to apply the blend in a power window / scaffold vs. the entire frame.

Perhaps it's a win32 thing.

The HDRx option appears to only exposed in the Mac version of 416. I just tried both the Win64 and Mac64. The Win version alternates between the two exposures as you step through the clip, so you can see what the two frames look like.

I'd like to second this and ask a favor. Please don't post anything using the rudimentary blending feature currently in build 416ER. It doesn't represent either the Epic or Redcine-X in an appropriate light. Some one will end up pixel peeping a low-res jpeg and pontificating on the technology. Not fair to show the results of a quick-and-dirty blend -- the magic of HDRx is going to come with a much more sophisticated approach that's coming down the line soon. Can't wait to see it!
 
Thanks for sharing, this is fantastic to see both exposures in one R3D...I assume HDRx™ slider/magic button is not in the current beta 416 yet and we are waiting patiently correct? :)

The remedial version is in 416... instructions how to use it were posted on page 1.

Hm.
Everything work perfectly, but once I fire up the Export module to set the DPX setting, the whole app becomes unresponsive. Could be, that I have just 2GB of RAM? Anybody can export or it's just my Macbook Pro?

It was my Macbook Pro at fault after all. My MacPro have no difficulties exporting DPX.
 
I'm going to break the "don't post" rule... because I can. Even with the remedial HDRx tools in RCX 416 you can see what HDRx is capable of. This isn't intended to be a final grade, just to showcase the power of HDRx that you have now.

Definitely it can work for a sort of still motion shots but I have doubts about a real motion shots (even a sort of "Magic Motion" is applied after)

just because you can't effectively "reconstruct" lost motion image parts even using today's best algorithms available.

Btw, I'm just experimenting about it using another camera and today all available motion blur plug ins...

My idea is to split HDRx in two variants/options:


1. HDRx using shutter speed that is sometimes with limited results according to motion blur artifacts...

2. HDRx using high ISO speed that can be always limited with high ISO noise floor of the sensor

BUT WILL DEFINITELY OFFER NO ANY MOTION BLUR ARTIFACTS AT ALL

that it should be based Epic MX sensor "deeper" noise floor than R1MX thanks to its higher resolution.

Also all is about that I wouldn't be happy to hear tomorrow that Epic HDRx is just limited to use for a certain sort of shots...

Sorry to disagree Sanjin... you are very wrong. Motion with HDRx is a plus, not a minus.

I did the motion version of this sequence (looks great)... just need Jarred to post it.

Ok, I'll overlook this breaking of my rule this once. But don't make a habit of it!

Seriously, though, can you explain how you got to that grade using current tools? I can't quite get there. What's your blend setting and curve settings?
 
Jim, thanks so much for posting. Looks great. How many stops of protection was this set at? Maybe +4?

Pretty easy... standard blend, a curve and Contrast to .50. New tools will make this more automatic.

Sanjin... you are trying to apply rules that don't apply to what we are doing.

Jim
 
He he... sorry Jannard, but I couldn't resist making my own HDR off the two JPGs. Hope you don't mind. :)

I could have kept more/all of the hot side of the clouds but that's not what I wanted to do.

There are a thousand ways to grade this... that is the good news. Best news is it works with motion. New tools are coming... this is just an early peak.

Jim,

I'm not trying to apply any rule just because I'm trying to discuss and to have my opinion about the topic even if I'm maybe not right at all.

It's more about discussion that is open here (also means that any competition can very fast get what they want to hear).

At the end I'm trying to say what I think that could be better option.

I know that I have a long record to try to "advising" RED for a certain solution but also must say that I was't so successful on that at all

BUT MUST SAY THAT I THINK THAT I WAS TOTALLY RIGHT WITH MY SOLUTIONS.

Also I don't need to say more and maybe older members of this forum should know more about it.

But anyway it's just about open discussion and we should continue now with topic on the tread...
