  • 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 :)

RED S35 or Panasonic AF100

"The Dynamic Range Stretcher, Gamma Select and other image features have also been inherited from previous Panasonic professional camera recorders."

To Quote Barry Green on DVX:

"The 170, 150, 300 and 370 all offer DRS. It's one of those functions that can be pretty amazing, or not, depending on the circumstances. It works by taming the highlights and gaining up the shadows. But what's really crafty about it is that it doesn't do it globally to the whole picture, it only does it where it's needed -- so it's sort of like having an individual iris over every pixel almost.

The highlight preservation is quite good, but the shadow detail comes at the expense of added noise, just like any other kind of gain."
 
Not quite HDR by definition, I get your point though. but i was under the impression that HDR, high dynamic range involved combined 3 different exposures to give you maximum end to end in dynamic range. I guess you can consider this another method of applying that. But if Scarlet gains the HDR mode that will be available for Epic eventually, there's really yet again not much debate. and with an 8 bit long gop codec, how much DR can this mode really give you. Sorry, I'm seriously a avchd hater. BIG hater.
 
Well, the Epic HDR is not using 3 different exposures either.... I would take a guess that they will be using a very similar method to Panasonic.

Have you used AVCCAM? I think it is a very good codec.

Thomas, that might well be the case with the AF-100 too, we will have to wait and see. Hopefully they will figure out how to do it on all frame rates though.
 
I have, but i'm a bit of a codec snob. I work with what I i'm given of course, but when you work with X amount that's so good, and get tossed something that Z amount that's this much worse, it turns you into a hater cause you kind of get in the groove of the more full raster codec. Better noise floors, holds more information top to bottom, how much you can push in the grade, and transcode degradation. Hate h264 as acquisition even more so that AVCCAM, I know it can yield some decent results, but with Panasonic having a 10 bit intraframe codec in their arsenal, I feel like it's a damn waste for a camera that's gonna fit into a really fine place in the market. Hopefully more items like the cinedeck, ki pro, and nanoflash are used for acquisition and can help drive the price down on these devices too.
 
Speaking of hacking, I'm kind of surprised no one has started hacking the firmware for the RED One. It should be quite a bit easier than hacking the GH1.
 
I think the firmware would have a great deal of encryption on it. Plus when you've got a 18k+ camera body on the line, do you really want to mess around with hacked firmwares? compared to a 1200 dollar or so GH1 body, the complexities and cost to loss ratio are a lot... I wouldn't touch a custom firmware for an r1 with a thousand foot pole.
 
I doubt anyone will be hacking the GH2 let alone the Af100 but that is just me. Plus that is not something I would consider when deciding on a new cam (till it's done) as who knows what the next hack will be, depends on which company leaves their door open next.
 
Oh, I agree with the practicality/usefulness, but I don't think that is what motivates hackers. If I had to guess, I'd say that the cost of a RED One (and only 8000+ units shipped) is what keeps it from getting the hacker treatment. They tend to have much more time than money. ;-)

I've also heard (not sure where) that the RED One runs Linux. If true, RED would be required to release the source code for the Linux kernel (and possibly other GPL'd utilities) used in the RED One if someone asked for them, per the GPL. Again, I think there are so few RED cameras out there that it probably won't ever come up. I doubt any actual RED One users care about any of this.

This sounds like a form of in camera knee and shoulder compression to keep the final encoded video within acceptable dynamic range limits. Kind of like tone mapping an HDR image, but not really a true HDR exposure process.
 
Everything subject to change!

Last week, he said they will do everything possible to get it into Scarlet, but no guarantees.

As much as I would love the HDR mode, if Scarlet can hit 11-12 stops in normal mode, i'd be very happy.

Jeff,

Why does this Panasonic thread continue while other Canon & Alexa threads 'walk the plank'? How is consistency of discussion measured from a 'mods' perspective?

...Because I have failed in my moderator duties and responded instead of locking the thread. Sorry, couldn't resist temptation. But you're right, we're equal opportunity discriminators around here. So it's closed.
