quality of image in widescreen
so when my after effects fils is burned to a dvd, the quality is reduced quite a bit. when I hooked up my laptop to the flatscreen directly, the quality seemed much better, but it was playing through windows media player, and I couldnt figure out how to make the movie full screen with no windows media frame. when the file is burned to a dvd, does the compression reduce the quality? Is my best bet to just hook the laptop to the screen directly and play from that? Also, what should the pixel aspect ratio be?

[pierre5454] “when the file is burned to a dvd, does the compression reduce the quality?”
Yes.
Your best bet is to compress to MPEG-2 using 2-pass VBR if your settings allow it.If your computer can play back the file from it hard drive, then sure, hook up the computer to the flatscreen. Maybe through the DVI/HDMI connection.
The pixel aspect ratio for computer hard drive playback should be square (1:1). So if the movie is 16×9, then its dimensions should be a multiple of 16 and 9: 160×90, 320×180, 480×270, 640×360 …. and 864×486.

SD DVDs use MPEG-2 compression, which can cause some blockiness in areas, especially if the shot contains fast motion/motion blur.
However, it sounds to me like your complaint is stemming from the fact that you’re viewing the DVD on your laptop, which is probably a higher resolution than a standard NTSC device (720×480) which will cause sometimes horrible distortion at Full Screen. For example, when you tell it to play at full screen on a device that is 1440×960 the video must be resized up 200%, causing any compression artifacts to be that much more noticeable in addition to the standard digital blocking you get when sizing anything up (Try sizing something up 200% in Photoshop without Bicubic Resampling… not pretty).
You should view your DVD on a set-top DVD player hooked into a standard NTSC device.
