I have a project I am working on for an artist. I need to make a dvd slideshow of his works.
This seems straight forward, but I am stuck on a few points.
I can make a fine looking slideshow in MF4 and it looks ok on the computer except for some dithering of colors, perhaps due to the source files being large tif 8x10 scans from transparancies. I have experimented a bit with resizing before creating the slideshow and that looks promising, but there is another problem that is a stopper and makes the dither moot.
Some of the art uses circles. when viewing the dvd on a wide screen plasma, the circles display as ovals with a stretch in the horizontal direction. Setting the aspect to 4:3 on the plasma makes them circles again. I already have tried setting the "display aspect ratio" to 16:9 and using two pass conversion and "best quality" and the resultant dvd slideshow still streches on a 16:9 progressive scan dvd play.
Is there a "best size" for the source files? Does the 16:9 setting really work at all on the slideshow maker?
I tried creating a tif black mat at 1366 x 786 and one at 864 x 480 and placing the resized tif files (matching the size of the resize to the smallest dimension) and the dvd conversion process still shrinks it and the display on a plasma still stretches.
I understand native resolution of dvd is usually expanded to wide screen on commercial dvds but I have seen some examples that do not stretch the image. Does anyone know how this can be worked around either within the program or in another program?
searching for info or workaround.

No, the resolution of dvd is whatever the video is defined as.
Big screen TV's can display as is or stretch/expand.
There are so many settings. There are many dvd aspect ratios.
What you are trying to do if working with a widescreen TV and you want the
picture to fill the screen is change source material that is close to native 4:3
ratio resolution to 16:9 ratio resolution.
The only way to do that is by cropping PART of the picture to 16:9
and saving the picture(s). But, you will lose the upper and bottom
parts of the picture to stay proportional. I'm saying PART because you
can use the rectangle as the template for cropping in many photo
editiors and when you fill the screen from left to right and maintain
a 16:9 aspect ratio you can't include all of the vertical information of the picture.
The ratio of pixels should be 16:9 for the pictures and make sure to set the
"Project Properties" to 16:9 in MF so as to produce a true 16:9 aspect ratio.
I don't think you will like it because of losing the information on the
top and bottom of the pictures to stay proportional.
I've done it a few times but usually just leave the source as is and
display the video as Normal 4:3. Still a big screen, just 4:3 aspect ratio.
Hope this helps,
