PAL Safe Colors

Post by david reece »

I know someone answered this recently.

I have done some research on the matter.

Interestingly i came up with a little tit bit re what images should be used in DVD making.

Supprisingly i discovered a Targa or a PICT file is preferable to a JPG file. Aprrently if you render a video the JPG gets rendered again and loses definition. BMP's were also a no as they are too big.

What i am having difficulty with is to get colors PAL saf.

I used Photoshop Elements 2 to do this. my pics are already set ag RGB. But i cant change the number of colors as was suggrested ie 0 - 255.

In indexed color i have the option to use speculative, patterned, dither etc.... adn set to 255 colors.

problem they lok awful when changed.

Anyone else with Elements 2 solved this problem for PAL safe colors and importing to Video Studio?

I am having problems with the color red in a digital still or scanned picture.

Elements 2 has an NTSC filter but no PAL filter.

I understand that if a color is not safe and it gets interlaced it will bleed over giving a distorted image or lines through a certain part of the screen.

Ulead have suggest that i chck i have PAL color filter checked in VS9 which I have. made no difference .

Any ideas?

I know it was suggested that i go for photoimpact 10, but i cant see it is no different to Elements 2.

Hi,

NTSC colors as represented in RGB are 16-235; we can't dip below 7.5 (the 16).

PAL can do better blacks; 0-235.

Both PAL and NTSC get squirrelly above 235.

thanks for response. i think you answered last time.

What i cant understand is why Ulead doesnt say you need to do this to get perfect slideshows etc..... you pic settings need to be this.......

it shoul also supply a picture editing package to do this or a proper filter to convert images in the first place.

Hi David,

Ulead doesn't need me to apologize for them, but VS9 is a very powerful NLE masquerading as a lowly starter appt.

You can edit much more than PAL or NTSC.

Because you can edit in any CODEC in your computer, you can edit Windows Media output or Real or MPEG 1 and 2 and much more, all of which can take advantage of a wider color palette.

i agree that vs9 is much better than any rival for price.

however if they have small photo package attached which automatically converted pictures to correct dimensions, format, PAL or NTSC safe color format that would be great. Perhaps in VS10 we will get something to help out. DVD Picture show has a photo editor of sorts. All they need to do is a limited edition photo editor that can only be used with Videostudio or even an import mode and as it is imported is resized and correctly colored to fit the TV system.

Going back to Elements 2, if anyone is using this, i eventually found the same thing you have in PhotoImpact 10. Dont ask me where it is, but if you look under recipes and colors it is in there somewhere.

I did a little test last night and set RGB to 0-235 still had some bleed in the picture so i set to 16 or 17-235 (which you suggest for NTSC) bleed had virtually gone. my concern is on play back colors to TV it will be wrong.

The bleed in picture i see is on the PC monitor as well as TV.

any thoughts?

Here is something i have picked up from iDVD.

For pictures use 16-235 for rgb regardless of tv format. That way you get a safe bet!

First it suggests add a gauss blurr.

Next add some noise to the picture. In elements 2 i added a level 3 noise with gaus blur checked.

next i changed the colors from 0-255 to 16-235 in the recipe section.

You have to do it in this order in PSE2. If you change colors first you get the layer in the picture locked out so you cant add blur or noise!

Play back on TV was fine.

Also try this when editing on a PC dont look to close at the screen when playing the video back. sit about 3-4 feet away! it helps! especially if you have lcd monitor.
