Highlight Color Change

RichardHK wrote on 9/15/2004, 7:45 PM
Dear All,

Have applied a nice button highlight mask (grey colour 128/128/128 A255) that works a treat in Preview mode. (Thanks again Gary!)

But, after prep and burn, the highlight has turned Green on DVD-R product. Everything else as per Preview.

Looks Ok but not what was authored, and not what client asked for. :}

Is this a bug? Or have I missed something silly? Cannot see any green color set anywhere.

Best regards,

The TV could be out of adjustment. Also the RGB color might not be mapping well into the TV's color space (a good reason to have an external monitor for preview). One thing you could try is lowering the green value; I'd try taking it down so that you just start to see a tinge of purple on the computer monitor.

Where or when did Gary mention about the highlight mask settings? Looks like I missed that one.

Scott,

Tried lowering color on the grey I am using, and putting all color set options to some shade of grey but still getting Green highlights after burning a disk. Quite lost as to what is wrong here. I am using latest DVDA v2.0a. CLient today was not too happy with green and I still have a few days to fix if possible. Most weird.

Clearvu - sorry. Gary's advice on the Cow Vegas forum got me started on how ot add a nice box around my image using a mask. Came here and found more info and a reference to the DVDA New Features pdf that completed the puzzle.

Best regards.

Positive that the television doesn't need adjusting? How many TVs have you viewed this disc on?

I doubt it is your TV. Usual problem is the Highlight Mask. Click on one of your buttons. Then, on the Properties area on the right of the main screen, find the Color Sets section and open it up. You then have to change the color for all four of the colors for Color Set 1 and Color Set 2. You may have to do this for each of your menus. Once you have created the color you want, you can save it as a Custom Color and then apply that custom color to each of the remaining color sets. You don't have to change the intensitiy of the color when you change to the new color, because DVDA remembers the intensity from the old color.

I guess I'm missing how the problem could be with his color sets? He said the highlights look fine in preview mode.

I will check another TV set tomorrow to be absolutely sure on that one. Have a grey background on same menu page that doesn't change at all between Preview and TV picture. So, my thoughts are that something is going wrong in the DVDA prep stage.

All colours in Color Set 1 and 2 are various shades of grey, and like I said, the Preview really works fine. Selected and Activated operate as I would like, but then the Green replaces grey when played from DVD-R.

Oops, I missed that. Sorry.

Have you tried pulling the background image into something like Photoshop and taking a sample of the grey to see what the RGB values are - then use those values.

The RGB values do get mapped to YUV; DVDA appears to be mapping RGB (128,128,128) to YUV (128,127,127) which is a little off according to the conversion program I just used; going backwards with these values results in RGB (126,128,126) - so the green is a little "hotter" than it should be.

It wasn't clear in your response regarding lowering the green value whether you dropped just green or lowered all the values. If you lowered all the values, try just lowering the green.

Yes, I did sample colours to get my highlights looking good (on the computer LCD) but have no greens anywhere in the DVDA menu or any color sets. Grays (greys) everwhere!

However, I did find out something interesting today. As said, the PC LCD shows good grey colours for Selected and Activated. The studio Sony monitor and Panasonic TV show a nice green Selected highlight, and correct lighter grey Activated highlight. These colours are from DVD-R burnt and played on a Chinese multi-system Shinsonic player. (5 years old)

BUT, my home TV shows correct highlights with my 8 year old Sony player. So, it has to be the DVD player in my studio that changes the colour. Also, the clients DVD player shows a lighter green which he quite likes!!

Conclusion, although still no idea why, is that DVD players react differently to DVD-R menu grey 128/128/128 range highlights burnt in DVDA. Weird like I said all along. How on earth I can make any difference I don't know. I assume 2.0b might fix it. :}

Have noticed the colour mapping does shift a little, by the way, but played with a range of grey values with same result.

Richard,

If you are trying to play the disk from PowerDVD or some other PC DVD playing app, you might check to make sure the overlay settings are correct for that app. I use PowerDVD and there is a section to adjust color, contrast, brightness, etc... You might check those as that would explain why it only has the green when played from your system. DVDA with an external monitor would bypass those color settings.

Just a thought...

intel i-4790k / Asus Z97 Pro / 32GB Crucial RAM / Nvidia GTX 560Ti / 500GB Samsung SSD / 256 GB Samsung SSD / 2-WDC 4TB Black HDD's / 2-WDC 1TB HDD's / 2-HP 23" Monitors / Various MIDI gear, controllers and audio interfaces
