Color change after burning BluRay with ArchitectPro
After burning my project to BluRay disc, using AP, the resulting disc shows a very different contrast and color balance when played back – much brighter than the original, with all colors looking pastelly and washed out, almost like a watercolor painting, except for oversaturated blues and oranges. I ruled out a monitor color issue by simultaneously running the disc on my computer and the project in Vegas Pro (V12, latest build) and comparing identical frames, side-by-side on the same monitor. Any suggestions appreciated.

It doesn’t matter that you looked at them on the same monitor. What matters is if your monitor is correctly calibrated. The problem you are seeing is because Blu-ray and DVD use Studio RGB (16-235) and your computer uses Computer RGB (0.-255) so the washed out picture is because you are probably editing in Computer RGB and the MPEG2 codec is encoding it as Studio RGB.
You need to first calibrated your computer monitor to Studio RGB. You’ll need a hardware calibrator like the Spyder 4 to do this accurately but you can also use color bars and do it by eye but it won’t be as accurate. It also depends on how good a monitor you have. Some inexpensive monitors can’t be calibrated to Studio RGB (i.e., you will never get the pluge on the color bars to display correctly).
Then when you edit, you need to use your Video Scopes in Vegas Pro and make sure that you make all of your luminance and color saturation Broadcast Safe. Use the Levels to keep your luminance between 0-100 on the Waveform Monitor and Color Curves to maintain the contrast you want. This should solve your problem.

Thanks, John. That’s useful – but it’s a new problem that I didn’t have before, so I wonder why it’s just starting now. While I have your attention, may I ask another question? On this same project, after rendering the whole 3 1/2 hour-long video and seeing the color phenomenon already discussed, I decided to split it into two shorter videos, each about 100 minutes, and burn it to two BluRay discs, avoiding additional compression. I have been trying to render the first of these two shorter and get 5% into the render when it just freezes. There is no warning notice, it just stops rendering. I have tried several times, to see if it stops on the same frame – it doesn’t, but always around 5%. My original project, by the way, is a nested file, which, as you know, renders the media files as it imports them. Not sure if this has any bearing. I also uninstalled Vegas Pro 12, build 563, and reinstalled, but no improvement. Any ideas appreciated.

I seem to have solved my rendering problem by turning off GPU acceleration.

That’s great to hear. I would have never guessed it was due to GPU acceleration. Thanks for getting back to us on this. That’s another thing to ask about in the future.

John, I also seem to have fixed my original color problem and thought you might be interested in how. My project consists of a number of different .veg files, that I want to combine together, for authoring in DVDA. I discovered that you can’t combine different files in DVDA and someone in the Forum explained nesting to me, which seemed the answer. So, I opened a new Vegas file, called it master.veg and did file/import/media to bring in each of my separate .veg projects. Then I rendered master.veg to mpg2 and opened in DVDA – and saw the color problems. The solution I found – and you probably already know this – was to open the first of my .veg files in Vegas, save it as master.veg, then file/import/media the subsequent .veg files in the usual nesting process. Color was perfect. Just FYI.
