DVI-HDMI-SDI Conversions and Color Space-what is happening?

Can someone explain signal processing when connecting computer monitors and LCD TVs via different connections and conversions?
- DVI to HDMI
- SDI (BM) to DVI
- SDI (BM) to DVI to HDMI
- SDI to DVI to HDMI
Are there differences in how each conversion processes color space? I am looking to keep it consistent when monitoring out of PPro and AE...latest CC versions...both PC and Mac workstations.
We never create media for typical broadcast or other conventional distribution. All media is custom animation for Special Events...large venue projection. But we do run multiple monitors and LCD for content creation and programming...many times running video thru a DVI Matrix or SDI Matrix for signal distribution. So I want to understand how each configuration effects video.
Does PPro always work in RGB? 0-255...AE as well? Or are there settings that must be set for this?
Thanks if anyone can help educate me!

That is allot of info there and I will list some to get you started
DVI - RGB
HDMI - RGB, YCBCR, or YUV
SDI - YCBCR
Premiere - No color management ie colorspace control. I believe it just uses the media and current display output color space. You would have to ask someone at Adobe there.
AE - Color management ie colorspace control. You can set what space your coming from and going to.
Do you have any colorimeters to calibrate your display devices? If not I suggest you look at X-Rite since it is cross platform OSX and Windows.

My computer, running on Lion, randomly flashes with crazy lights and colors. Doesn't happen often, but when it does it's totally random. What causes this problem and how can I solve it?

My MacBook Pro, running on Lion, randomly flashes with crazy lights and colors. Doesn't happen often, but when it does it's totally random. It looks like the Northern LIghts!!!

Really? Oh I get it. You're the kind of person who goes on tech message boards to make jokes - or friends.
Well, I'm trying to solve this problem - which is a rather annoying way to spend a Saturday.
SO either help or don't reply.

HD TV or LCD monitor with HDMI,DVI supported to preview and color grading

Finally I got my canon HFS100 and Intensity Pro now what type of the monitor should I get to preview and color grading video via intensity pro between HD TV or LCD monitor with HDMI,DVI supported and how to calibrate monitor via intensity pro.
Please help.

The main downside is that an HDTV is designed to be used at TV viewing distance. So it would work fine for presentations, where the audience is sitting more than 5 feet away. But at typical computer screen distance of 2-3 feet, it is the same 1920x1080 pixels spread out over a 32-inch screen. Oh, actually, that HDTV you mentioned is only "720p", which is only 1280x720. That may not look all that good at TV distance either, if you are displaying images that are static (non-motion).
Your eyes will have to work harder to see the same screen real estate, because everything is bigger on the screen. Images and text will not look as sharp (more pixelated) because each pixel is larger. It won't be like using a 30-inch Cinema Display, which has 2560x1600 pixels. Each pixel on that 32-inch 720p HDTV is more than 4 times larger.
A 1080p HDTV would be somewhat better, because that is 1920x1080 resolution.

Lightroom,Nik plugins and color spaces

I'm having an issue and not sure who is holding the smoking gun. I have the Nik ultimate collection installed which covers Lightroom and Photoshop CS5 extended. I work primarily in Lightroom and apply most corrections globally but occasionally i need to do localized adjustments so the photo gets shipped off to Photoshop. Here's a typical scenario:
1) From Lightroom edit in Dfine 2.0 for noise - as copy with Lightroom adjustments which gets copied as a tiff.
2) From Lightroom edit in Viveza 2 - as original since we're now working with a tiff and I don't want a copy for every single thing I'm doing.
3) Edit in Photoshop
Now there's two issues at this point:
1) The edits do not show up in the Lightroom history - it's like nothing happened.
2) Photoshop will complain that the assigned profile is sRGB. Really?
#1 is a PITA because if I want to rewind I have to start all over since there's no history - what exactly is responbsible to set an edit as history? Lightroom or the plugin?
#2 is by far the most serious as it degrades the work in a seriously bad manner. I mean, WTH - I'm moving along in ProPhoto Ferrarri space and all of a sudden - *boom* - I'm running in sRGB moped mode.
I looked at edit->Preferences->External Editing -> Additional External Editor and indeed when I select the Nik plugins from the combo box preferences the default for the plugins is sRGB. I can change to ProPhoto and quit. I repeated this for each plugin assuming that somewhere the setting was remembered. Nope LR acts dumb as a rock and shows sRGB as the defaults for all except the currently selected plugin.
So my questions are:
- who's gonna own up to the problem - LR or Nik?
- how can I work around it?
- how can I make LR remember the settings? Not a registry key nor INI file in sight to set them - so where/how are the plugins tracked?
Thanks for any help!
Jon

Jon,
The User Interface for changing how external editors are invoked is about as smart as your average chunk of granite.
After you change the Color Space to the one you want, you have to click on the Preset box and choose "Save current settings as new preset...". Not exactly intuitive, but there you are.

Web Gallery and Color Space

Hi,
Is there any way to change the color space of the Web Galleries made by Aperture from Adobe-RGB to sRGB without exporting the photos separate first.
I'm also missing an adjustment option to set the image quality in the Web Gallery.
Regards,
JO

I am slightly confused by what you said...
without exporting the photos separate first.
Do you mean change to sRGB while still in Aperture? The answer would be no. The images get changed to sRGB on export. However, you do not have to export the images separately from the gallery. When you create the gallery, the images and html get created all together. So, what you do is change the export presets you are using for the web to have sRGB in the color space profile.

Export failed to meet required bit rate and color space specs - ProRes 422 to MPEG2

Using Premiere Pro CC v7 I exported a ProRes 422(HQ) file to MPEG2 and selected the HD 1080p 23.976 preset. I needed the finished file to have a minimum bit rate of 50Mbps and the color space to be YUV422. I was way under the minimum bit rate and the color space was incorrect. Can someone please instruct me on how to achieve my desired results. Thanks!

The source frame rate is 23.976, so I guess I would go with 24p. My intention is to upload the file to a streaming video website. They have their specs laid out for me, I just happen to be new to all of this so I am having a tough time meeting them.
My question right now is, if i have selected the MXF OP1a XDCAM option with XDCAM 50 NTSC (4:2:2) video codec, will the export be in mpeg2 and what will my bit rate be? I have no way of viewing the bit rate with this configuration.
Here is a screen grab of their required specs:

Quick develop and color space ...

Ok, I know that library module previews are in Adobe RGB.
So, we view files which are in Adobe RGB.
But what about editing?
What color space we use when adjusting in quick develop in library module?

Thank you for such a clear summary.
Do you know why does Adobe not use Melissa RGB in library mode previews?
As far as I can see, assigning an Adobe RGB profile to a JPG file and assigning a ProPhoto RGB profile to a JPG file does not create any difference in file sizes.
Is there a disadvantage of using Melissa RGB in library views?
Melissa RGB isn't really a supported RGB working space. That is, it's not something you'll find anywhere outside of LR unlike say sRGB, Adobe RGB (1998), ProPhoto etc. It isn't installed or used by any other Adobe app. It's kind of a strange beast too: ProPhoto RGB with the sRGB gamma TRC. We'd have to ping the original LR architect (Mark Hamburg) to find out why he decided to use this odd space solely for RGB values and Histogram but I suspect the main reason is that viewing a linear encoded Histogram would confuse most users (it would look 'odd'). I can't say why he didn't just use the ProPhoto 1.8 TRC instead but that's water under the bridge. This space is not ProPhoto RGB due to the gamma encoding and it isn't used for processing! Only the RGB values and Histogram.
The actual color space used for processing has no name. It IS ProPhoto RGB primaries with a 1.0 TRC.
I suspect that using Melissa RGB or a similar huge gamut is unnecessary in any preview mode because:
1. Being so big, you'd want high bit (16-bit) data to reduce banding and that's overkill.
2. There isn't and never will be a display capable of previewing ProPhoto gamut.
3. There are a few displays that get close to Adobe RGB gamut, we may see that grow in the future. So might as well use that large gamut color space for previews. IOW, ProPhoto is way, way too big, sRGB is too small considering we have wide gamut displays.
IF you have Photoshop, you can build Melissa RGB and save that out as a profile. Only useful if you want to play around but has no practical use. In Photoshop's color settings, select ProPhoto RGB as your working space. In the same menu, now select "Custom RGB". The dialog shows you the "DNA" of ProPhoto RGB (white point, chromaticity values, gamma). Change the gamma to 2.2, save as an ICC profile. You now have Melissa RGB. You don't get the true sRGB TRC but a simplified one, but close enough.

Image Format and Color Space

When I import photo stills into imovie to make a slideshow, does it benefit me if I export the raw photos from Lightroom as 16 bit Pro Photo RGB tiffs and then import those into iPhoto? If I plan to show these on a television, what would be the best color space and format for my images?
Thanks for the help.

Java can read JPEG and GIF images. Startig with JDK 1.3, it can also read PNG images. Java 2D (available in JDK 1.2 or later versions) has the capability to write JPEG images. The JPEG codec is in the com.sun.image.codec.jpeg package.
The Image IO API is available only in JDK 1.4 (currently in beta).
The Image IO framework allows third party vendors to write coder/decoders for any image format. For this purpose, the Image IO API provides the SPI (Service Provider Interface). This framwork allows you to use codecs of your choice. I think JDK 1.4 comes with the JPEG codec, but not GIF.
Java Advanced Imaging (JAI), which is an extension to Java, has coder/decoders for several image formats, including JPEG, GIF, BMP, and TIFF. To use JAI, you need to download it from the Sun's Java site.
According to Sun, because the Image IO API has been developed to replace Java 2D and JAI codecs,they won't be supported in future releases.

MacBeth chart - Adjust Color Space - What do I do next?

I have watched Colin Smith's Speedgrade Tutorial: http://tv.adobe.com/watch/no-stupid-questions-with-colin-smith/introduction-to-speedgrade/
Very well done. Thanks!
One question remains:
Using a Canon 5D MIII, I have shot a MacBeth chart (X-Rite Original ColorChecker Card) and was able to successfully use the “Go” button under the “Clip" tab and then sub tab "Color Space” checking “Override input format’s default color space." The adjustment is amazing and the it surprised me how well this turned out.
However, now I have a color corrected 2-second video clip of a MacBeth chart. Where do I go from here? I have 50 clips and cannot use LOOKs to store this adjustment as it is in the color space world. Also, I seem to fail storing the actual color space in any way. For test purposes, I have made a screenshot of the Exposure, Black Level and Matrix settings and then entered the 15 numbers into another clip with great success, but this is a bit tedious to put it mildly.
Any advice is appreciated!
Thanks!

I've done some checking on this. With the way ALL timeline-affecting things have been locked down for Direct Link work, this is NOT available in DL workflows. Very unfortunately, in my opinion ... which is sometimes very humble, but in this case, not so much!
Please file BOTH bug AND program feature requests on this ... invite your friends to do so also! Not only is the Passport color-checker chart quite a useful production tool, there are a couple similar things for video that are even better. NONE of which are usable in a DL flow.
Except ... that you can start in native mode creating an ircp file, do the same thing as done in that tutorial you referenced, save the results as a Look, and then apply that Look say in an second primary just above the footage primary during your normal DL workflow. Then apply any basic WB style color cast corrections to the lowest primary. It would be similar to the way a LOG style LUT/Look correction layer is used.
Try this and see how it works.

Canon Pictures Style and Color Space

Hello!
I need some clarifications.
If I well understand Aperture do not consider the Canon setting for Picture Style when shooting in RAW.
Is it correct?
The same is valid for the color space.
Thank you!!!
Max

Yes...You understood! Thank you very much
What about the color space when shooting in RAW? I noticed that even if my camera settings were sRGB, Aperture shown Adobe.
Thank you!
Max

Help!! As I was scrolling through my library, one folder after another had the photos in it turn to "static"! Lots of streaks and dots! What is happening and how do I save my photos?

As I was scrolling through my Aperture library just now, I saw one folder after another turn the photos in that folder into garbage! They have lines and dots and nothing recognizable - what in the world is causing this? Can I get my photos back? It almost looks like a virus eating my files - could it be - and if it is - is my entire computer in trouble? HELP HELP HELP!

Interesting that you posted this Cleaning up photo library about one hour before this post. I'd say there is a good possibility they are related.
Without knowing your system, OS version and Aperture version and what you were doing to 'clean up' your library there is little we can do.
My photo library is a mess. I have moved things around a lot in a futile attempt to organize them, now I have a lot of placeholders with no files attached. How do I clean things up?
I suggest you restore from your backup and forgo the cleaning operation until you have a better grasp of the situation.
BTW the Masters folder is organized by date and time of import at least in Aperture 3, if you are using 2 then all bets are off,
Good luck with Apple support, if you want to try and get this sorted out post back the information I requested above.

SetRollbackOnly and EJBException..what should happen?

I am wondering what peoples opinions are about what should happen when commiting a transaction in the following scenario.
I have a transaction started by a stateless session bean method. This method just finds an entity bean and sets one of its attributes. When this stateless session bean method finishes, the transaction is commited by the container. While commiting the transaction, the container calls the ejbStore method of the entity bean. The ejbStore method calls a method on a different stateless session ejb. This stateless session ejb method calls setRollbackOnly and throws an ApplicationException. The entity ejbStore method catches the ApplicationException and throws it nested within an EJBException.
The ejb2.0 spec says that the container should throw a javax.ejb.TransactionRolledbackLocalException if it can't commit a transaction. This is what I receive, but my question is what would you expect the nested transaction to be?
I would expect the EJBException that I threw from ejbStore to be the nested exception.
ie. I would expect this....
javax.ejb.TransactionRolledbackLocalException: Error committing transaction:; nested exception is: javax.ejb.EJBException: nested exception is: au.com.sparq.test.ApplicationException: ApplicationException a b c...
But as soon as setRollbackOnly is called, I will only ever receive this exception....
javax.ejb.TransactionRolledbackLocalException: Error committing transaction:; nested exception is: weblogic.transaction.internal.AppSetRollbackOnlyException
Why is an AppSetRollbackOnlyException being thrown by the container when I have told the container to rollback the transaction by throwing the EJBException from the ejbStore method of the entity ejb? In this case, the container shouldn't care that setRollbackOnly had been called. It should only be if the ejbStore method doesn't throw an EJBException that the AppSetRollbackOnlyException is thrown.
The side effect of this behaviour is that I can never get access to the ApplicationException thrown within the ejbStore method, so I can never tell what caused it to fail.

This is the expected behavior since Windows XP/Windows Server 2003.

Photoshop PDF resolution and color space difference: Acrobat vs. Photoshop?

I have received several Photoshop PDFs from different sources. In Acrobat, the document properties indicate the PDF producer as Adobe Photoshop for macintosh -- Image Conversion Plug-in. When checking the image either with PitStop or through Photoshop via Acrobat's Touch up object tool, the image shows as a 100 dpi RGB image. If the PDF is opened directly in Photoshop, Photoshop indicates it is 300 dpi and CMYK.
Does anyone know why there is this difference? Also what is the Image Conversion Plug-in and how does it work?

Ah, sorry; in that case possibly the Preserve Photoshop Editing Capabilities-button was hit (thus including the original psd-file) but a low-res-pdf-setting selected.
In which case the original data would appear to be CMYK and of a higher resolution that the pdf-images.
