Codec that supports 16 & 32 bit per channel color?

What Quicktime 7 built-in codecs support hi-bit 16 & 32 bits per channel?

I assume you're working with image files.
The Animation codec supports 16 (Millions of Colors) and 32 (MIllions of Colors+). Great, fast encoding, high quality video.
Photo-JPEG uses 32 bit.
If you're only using a single frame your could use TIFF, PNG for 16 and 32 bit and Photo-JPEG for 32.
What is the goal of this project?

16 bit per channel images

I have been using BufferedImages for image processes but now I need to use color images that are 16 bits per channel. It doesn't look like I can use BufferedImage for this. Does anyone know how I can deal with this?
Basically what I need is
BufferedImage bi = BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
bi.getRGB(i, j)
bi.setRGB(i, j, color.getRGB())but with 16 bits per channel instead of 8.
Thanks

Hi,
That is not a limitation in full photoshop versions such as photoshop cs6/cc.
That's only a limitation in photoshop elements.

Why does PS show only 256 color Steps in a 16 Bit per channel workflow

Hi forum-members,
I am a bit confused about the way PS (CS5) acts with colors when editing pictures (RAW-converted) in RGB 16 bit per channel mode.
(please don't mind, if I am using some wrong English expressions here - since the PS at my work is German)
--> I would expect, that I would be able to select from a variety of 65535 (=16 Bit) color steps for every R - G or B channel ... bus PS still let's me select just 256 (=8 Bit) colors per channel (in the color palette on the right - also the "color pickup tool" will show 8 Bit values - the image certainly has 48 bit color depth).
Why am I asking? I will get a display capable of displaying 10 bit colors per channel in PS (NEC PA241W, ATI FirePro V5800, DisplayPort --> 30 Bit colors in Adobe PS) next week. And thus I need a better color resolution (which would mean: 16 Bit in PS) to avoid banding-effects.
Does anybody know why I can't select more colors here or how to change this behaviour?
Thank you very much in advance for your answers!

Hi Mark,
I already managed getting it to work :-)
First I did not succeed and I had to reinstall my system (because of driver issues of the remaining nVidia driver - my old card...).
After reinstallation and performing all necessary steps (as descripbed here: http://www.amd.com/us/Documents/48108-B_ATI_FirePro_Adobe_10-Bit_FAQ_R5_Final.pdf) I now get 30 Bit color ...
... which is AMAZING! You really can see the superior quality in almost every picture. Colors are very accurate and especially in dark shadows or skys you get a much better color rendition (now its indeed hard to see the color values of a color gradient anymore...).
Also have a look at this page related to 10 Bit output: http://www.amd.com/US/PRODUCTS/WORKSTATION/GRAPHICS/TOOLS/Pages/tools.aspx
And don't forget to download 'ramp.psd' from the page above - it's a good tool to proove wether everything has worked - if you're really running on 10 Bit you will not be able to see any banding within this picture (with 8 Bit you'll see a few vertical bars... moving up to 10 Bit will result in a smooth gradient)
As with every good news there are also some annoyances (at least till now, since I think it's "only" driver problems ... so there's a good chance, things will change further in the future):
- First of all: 10 Bit per channel ONLY works with the "professional grade" graphics cards (ATI FirePro), don't try this with a Radeon type card - it simply won't work. Similarly nVidia adds 10 Bit support on display port only on the QuadFX series (very expensive!). And I just can speak for ATI FirePro cards, since this is, what I am using here. Since the cards are physically identical to the "gamer" versions I think this is a way to promote their "professional grade" cards by the vendors. (BTW: all supported ATI cards are included in the pdf mentioned above)
- ATI: with the latest ATI driver (8.7xx) will loose some abilities (OS is Windows 7, 64 Bit): first, you will loose your Aero display features, since there's some background process running that prevents Win7 from using Aero. I guess, this could be due to a lack of alpha blending capability of the driver (or hardware?) when used in 10 Bit mode. If you don't need 10 Bit it can easily be turned on and off (+ Reboot), so that the effect is NIL in "normal" operation mode.
Second I recognized some trouble using certain apps: especially playing BluRay get'S trouble, for HDCP is not detected anymore - the BluRay player tells, that HDCP is not supported by the monitor. Again, the error is gone if switching back to 8 Bit mode.
- There's no way to select the "new" colors in Adobe PS (this is - in my opinion - a bug in Adobe PS and should be fixec someday). I "worked around" this by generating a 16 Bit RGB picture with a smooth gradient --> now you can pick even the finest colors using the pipette tool... which works fine.
After all: working with 10 Bit p.C. is a great pleasure! Of course you need 16 Bit RGB pictures (which are huge sized) to get the plus in color rendition - but I am well willing to pay the price - the images are just looking great (and the PA241W is the right tool to get there - a very well made monitor! Really worth the price - equally addictive like Eizo's GC series).
Hopefully I could help you - please don't hesitate to reply if you need further assistance!
Best regards
Roland
P.S.: Yes, this forum is WAY better than most on the net - very reliable and professional support! With support of "real" Adobe engineers - congratulations, Adobe! Very much appreciated.

32 bit per channel

Does the 32 bit per channel retain the sign if negative through processing, saving and then reading? It is advertized as floating point.
RONC

they are handled In the same way but in a linear version of the color space which makes a big difference. Search and learn about linear vs non - linear editing.
here's one link about it. http://mysite.verizon.net/spitzak/conversion/index.html
when reading the information in the above link have in mind that although the author talks about sRGB this is valid for all RGB color spaces which have non-linear gamma.

Open a HDR 32 bits per channel file in photoshop elements.

Photoshop elements 4 with a hdr 32 bits per channel file in rgb mode opened and being converted to 8 bits using the built in hdr conversion dialog.

If you want to open RAW files with JavaScript I would recommend you record the process with ScriptingListener.plugin and use the resulting code.
It is possible with the Document Object Model, too, though.
To see the properties you can refer to ESTK Help > Object Model Viewer or Photoshop-CS6-JavaScript-Ref.pdf.
But if Muppet Mark’s advice applies maybe you can stick with AppleScript for this.

Cannot Change From 16 to 8 bits per channel

I have never had this happen before: I cannot change the image I am editing from 16 to 8 bits per channel. Also odd is when I click on an adjustment layer I have created it is not highlighted in blue.
Thanks

See if your in quick mask mode.
Icon at the bottom of the toolbox and look at the top left of the document window and see if it says quick mask.

IOS version that support 2048 bits certificate

Hello,
I need to update a 2504 Wireless Controller to a version that supports 2048 bits certificates.
I´m checking release notes for release 7.4.110.0 and I don´t see any information about a limitation in certification size (2048 bytes in my case).
Do you know any restriction about the certificate size in this or another version?
Thanks and Regards.
Iván.

2048 bit is supported on the WLC. I use it for WebAuth and 3rd party certificates as these vendors only issue 2048 these days.

Does Mavericks add support for 10 bit per channel capable monitors

Just bought a HP Dreamcolor z27X monitor and have a new Mac Pro 6,1 and would like to know if my workstation supports the full capabilities of the monitor I just purchased.

JonB8305 wrote:
10.9.3 still doesn't add the 10 bit support.
That 'is a strong inhalation of breath' (forum will not allow s..ks). I have to say Apple are falling way behind in terms of supporting current media standards.
Not ony has 10bit video been around for quite some time now and is something used and supported in Adobe products in the Windows world, but Apple have also failed to support HD audio standards as used in Blu-Ray as an example and also look like failing to support H.265 as will be used for 4K video. (H.265 is twice as efficient as H.264 making it far more practical for the much bigger bandwidth requirements of 4K video.)
Now in the case of HD audio and H.265 it might be that there is no justification from a playback point of view from Apple's perspective, but what Apple appear to have forgotten is that Mac used to be the first choice for creating media files and if Apple don't support these standards then Macs can no longer be viewed as being suitable for media creation. Therefore this is a huge own goal on Apple's part as content creators would be precisely those people looking to buy new Mac Pro systems and Apple have at least designed the hardware to support 4K editing even if their software is increasingly too feeble to support the required standards.
Note: I have previously submitted an enhancement request to Apple regarding 10bit video support, and also H.265 support, both prior to Mavericks being released.
I have no problem with Apple not supporting Blu-Ray playback in the form of providing themselves a Blu-Ray player. However as above I feel they should make the Mac or more accurately OS X able to utilise the same formats as this will allow both content creation tools, and also the possibility for a third-party Blu-Ray player that supports HD audio formats. It is apparently possible for a Mac running Windows in Boot Camp to play these HD audio formats which makes sense since Macs use pretty much the same hardware as 'real' PCs so it is just OS X that is the problem. In fact the way things are going even Linux is moving ahead of OS X in terms of media format support.

Codec that supports 0,75 aspect ratio 1920x1080

Hello there.
My camera happens to churn out 1920x1080 0,75 aspect ratio 25fps MP4 videos. GSpot also gives the following information; Codec: avc1 and Name: H.264/MPEG-4 AVC. Hopefully that's enough info.
Usually these work just fine with After Effects, but this is second occasion I actually have to run them through Media Encoder to get them working. Should not be big deal, happened once before and After Effects did accept files after they had been once encoded. The problem is, I don't seem to be capable of finding format that suits the said video type. All I want is as identical as possible file that I can work with. First I thought I'd simply use H.264 -> Nope, you can't choose 0,75 aspect ratio and it squeezes video and adds black bars. Annoying. I tried few formats that had customizable aspect ratio (sliders... annoying too). They have varied resorts, some screwed up quality, some didn't allow me to use that high resolution (told me to increase level or profile even though they already were as high as they could) and some produced enormous files without the same quality.
Seriously, could you point me to fileformat/codec that keeps the same/similiar quality, supports aspect ratio like that and let's me continue my work? Messing with these encoding settings is almost enough to make a grown man cry. Remembering how much trouble I had last time (in the end resulted in enormous file size with almost the same quality, ridiculous) even thinking about this stresses me bit too much for my liking.
Thanks in advance.

Hey, Mark. Thanks for your time.
Forgot to mention, it's interlaced. Good thing you included suggestions for both, though.
What makes you think the source content is 1440x1080? I'm quite sure it's 1920x1080, as it's the number given everywhere. I tried the H.264 Blu-Ray format, but it once again gave me the black bars both with 1440x1080 and 1920x1080. The 1920x1080 one was closer to the truth.
So the problem still stands, any further suggestions would be much appreciated.
*edit*
Here is example of footage incase some of you want to try it out with your own encoders.

It´s thrue that there´s a MB that supports 64 bit and 32 bit processors?

hi.. i have an amd 64 bit but i don´t like it so much because there are no programs to use it well... so i´m thinking to change myself to an intel P4 but i work with graphics and i don´t know what to do...
... a friend told me that there is a motherboard that supports bouth 64 bit and 32 bit processor...
can you confirm this?
if you don´t, please help me..!!
any solution is well recived...
DC

Although someone mentioned about the 865PE Neo3-F which maybe one but no one can confirm this as none of the manufacturers has brought it up yet but the fact that Prescott moving on to 64bit may be possible.

How can simple tools be used in 32-bit-per-channel images?

I have just begin working with HDR imaging. I am using it for what it was designed for. The subject of the photograph is a creek, looking straight across the creek to the far bank. The creek and the far bank are in bright sunlight. I was in woods, and deep shadow, when I took the photograph, and so the foreground is very dark. I converted the image to 32 bits/channel when merging it into HDR Pro, and used ACR to tone the final image. All of that worked very well.
But when I wanted to make some final little adjustments to the image, I found that I coulnd't! I wanted to select a color range, but the Color Range option was grayed out. I tried to use the magnetic lasso, but a message box popped up saying that I couldn't use that tool in 32-bit images.
I don't understand this limitation. 32 bits are supposed to be best for HDR images, but I can't use simple tools to edit the result?
And then when I switched to 16 bits, it seems I have to merge the channels first, but that loses all of the smart filters and other history that I had when working in 32 bits!
What is the best workflow for doing this? Is there something I am missing that would help?
Thanks very much!
RobR

Thanks again for helping me understand.
But I'm afraid I'm still a fair bit mystified. I'm trying to move away from why 32-bit is different from 16-bit and into what is the typical workflow for an HDR image where the goal is a realistic scene.
Are all edits typically done in ACR? Or do people accept the loss of the ability to use ACR when they switch to 16-bit mode to get the simple tools like selection, dodge/burn, and so on? It seems to me that the best of both worlds is to save the ACR-only version of the image and then convert to 16 bits and, once final editing is complete, to save that version separately? That way, should the ACR need to be adjusted, it could be done starting from the original settings, and only the 16-bit changes would need to be redone manually.
Thanks again.

Photoshop CS5 - Current Users of 10 bits per pixel color

Hello,
I'm looking for feedabck from anyone who currently has a full 10 bit display pipeline using Photoshop CS5. I've got a question in on another thread about info on 10 bpp hardware support but I wanted to also start a new thread to get comments from users who are already there.
First and foremost I would like to know what graphics card you are using, and second your monitor and the color space you're using. Info on drivers, calibrations tools you may have used on the monitor, performance differences you may have found going from 8 bit to 10 bit, your OS, etc. would also be appreciated. Of particular interest would be anyone who has been able to get a non-workstation graphics card working with 10 bits all the way through. I believe this is only possible with DisplayPort, although I have seen information that workstation level cards can do it over DVI.
Please!! no Luddite style comments/questions about "why anyone would want to do this", or "what a pain it will be", or how "8 bits sRGB color is perfectly adequate and wonderful" for everyone. I've essentially been there and done that in terms of reading these comments and I have less than zero interest in hearing any of them, no matter what your level of experience. If I stated this as strongly as I would like I'm sure I would violate forum rules on language, so please respect my wishes here and start another thread to bash 10 bpp or wide gamut color in general.
I'm only interested in getting tips on what is needed to make it happen. Others who are not there yet but with legitimate interests in 10 bpp color feel free to expand on my questions.
Thanks.

I don't have a 10 bit pipeline myself, BUT...
I did run across one interesting tidbit with regard to using OpenGL with Photoshop through ATI video drivers...
A while back, as I was developing a plug-in that uses OpenGL, I observed that the ATI Catalyst driver (for my Radeon HD 4670 card) was choosing a deeper format for textures than what was requested (16 bit half-float instead of 8 bit integer) but only when my plug-in was running as part of Photoshop. When I ran the plug-in in another app it did not do this - it stayed with an 8 bit texture depth instead.
It turns out (confirmed by an ATI engineer) that the video drivers were actually detecting the application being Photoshop and making different decisions - presumably to increase the quality of the display specifically for Photoshop to support the high quality 10 bit color pipeline you seek.
More info here: http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=281068
The key thing here is that prior to this discovery I never suspected that a video driver might do things differently depending on what application is calling it.
Good luck putting together a system that gives you that higher quality display. I'll be keenly interested in reading about your discoveries here.

HT1536 .AVI codecs that support retina display.

Is there one that works?

All was fine until the organiztion's PC went south (10years old). I am covering with my personal equipment until a replacement can be approved and aquired. As fate would have it I just recently replaced my dying MacBook Air with a !3' Retina MacBookPro.
Thanks for the apmplifying info. This is a "horse of a different color." Had thought you were referring to the "Retina" iPad. Platform display type should not make a difference, Mac OS X version, QT player version, and compression format(s) used in the AVI container make all the difference in the world here.
Basic question is whether or not you have installed Perian and the QT 7 player app on the new system. Perian plus the QT 7 player basically support most AVI compression formats currently compatible with Mac OS X operating systems. Remember AVI is a legacy file format that has not been supported by Microdoft for more than 11 years. Some PC codecs have never been transcoded for OS X or Mac Intel platform use, some AVI files simply cannot be played by the QT players.
I have been unable to get .avi video to play on the MacBook using QuickTime Player and Flip4Mac. Neither currently supports .AVI for Retina is my understanding. I am looking for a temporary solution to just time play .AVI files once and done.
The real question is "what compression formats are you trying to play?" and "in which QT player on your new system?" If both QT 7 and Perian are installed and if the QT X player cannot play the AVI file natively, it will normally ask the user if he or she wants to play the file in the QT 7 player. To further complicate matters, since the introduction of Lion, Apple has, by default, turned off legacy codecs used by the embedded QT structure which were normally used natively for AVI export.
If playback is all you are interested in, then VLC can be used for this purpose since it includes its own codec resources within the app. The QT 7 player plus the Perian codec package provides similar playback capabilities. On the other hand, if you want to play and/or convert common AVI codec content to QT compatible files without purchasing a commercial conversion app, then you can use Perian (for decoding) and either QT 7 Pro ($29 USD) or the free MPEG Streamclip app (for encoding to any available export codec for which your system is configured).

Debanding from 10 bits to 8 bit per channel

if i have a video file with 10 bit/channel and i would like to encode that to a 8-Bit h264 file... and, of course i get a lot of banding. is there a tool or a plugin in premiere that does ordered dithering (10 To 8 Bit) such as a floyd steinberg algorithm (to get a better quality than by adding noise to blurr the banding)? thanks

The color setting is change from 32-bit color to 8-bit color?
Sometimes the Windows display is affected by compatibility settings in your Firefox shortcut, the icon you use to start Firefox. If you right-click that and choose Properties, then click over to the Compatibility tab, here is where you would indicate that you want Windows to look more primitive when using Firefox. For best results, UNCHECK everything on this tab (in other words, use all of the capabilities of Windows XP).

That website is using an old method of checking the encryption level a web browser is capable of, it mentions Netscape 6.x/7 which are like from 6 to 7 years ago. It looks like they're checking for a '''U''' in the User Agent string. That particular letter in the UA goes back to the days of export controls for encryption software, but those controls expired over 15 years ago. That letter has been virtually meaningless since then. <br />
