TV & Monitor aspect ratio

Hi,

I have captured a DV clip from my DV camera connected to an analog source, the clip is 720x576 ,but there are some black bars on the top ,left and right sides , the
left side is bigger than the rest.

After importing it to Vegas 3.0 , I am trying to create a multimedia
version of it and encode it to MS MPEG4 V8 or to Divx.

Since DV aspect ratio is 4:3(720x576) and computer monitors are
1.33(800x600) , I can't just resize it because this cannot be played
on a PC in fullscreen (it creates black borders on the sides).

What can I do to create a 1.33 version that will play correctly on a
fullscreen mode without distorting the DV image ?


I have to mention that I want to be able to crop the borders coming
from the DV file (the source is analog and the camera is used as a
convertor).

After encoding to some sort of computer video format , I want to be
able to watch it fullscreen and output using my computer's Tv-out to
my TV and watch it.

The problem is that even if I can make a fullscreen version with no
borders I still have to output it to TV and then the correct image on
my PC screen looks verticly streched on my TV.

This aspect ratio is giving me an headache , can someone help out and
tell me how to resize the DV source to be able to watch it correctly
on a PC monitor (with no borders) and avoid distortion on my TV
screen? I want to render one version that I can playback on PC resolution 800x600 with no black bars or distortion and when outputing to TV using my TV-out to get non-distorted picture as well.


you help is appreciated.


thanks

Same answer I gave earlier: You want a VCD.

I know it isn't easy. Join the club.

No,

I don't want a VCD , since most times you play VCD using a DVD or a standalone VCD player. I need to be playing from the computer , while streching (fullscreen) correctly on a 800x600 monitor and outputing it to a PAL TV which created a correct aspect ratio on the monitor and streched (vertical) output on the TV.

any ideas ?

What you want and what you can have are different things. While you can hook up your PC to play through your TV the results typically leave a lot to be desired. To put it another way while you can force square pegs into round holes, doing so tends to knock off the corners. IF you are using a DV camera I would suggest you output 'print to tape' and then play from your camera. That should give you superior quality. There's lots of things wrong with hooking up a TV to a compter directly. RGB values are different, aspect ratio is different, pixel shape is different. If you go the VCD route or better burn to DVD if you want to run out and buy a DVD burner, using a set top DVD player will automatically resize the picture for you since you main objection seems to be those "bars" you refer to. For example if you burn a CD as SVCD the default NTSC value is 480x480 which played in a non DVD player on a computer will look distored. However play the same file on a set top DVD player and it will be of correct porportion.

Of course you are right , but SVCD are not as compressable as Windows Media or Divx and if I can store about 60 minutes of quality (relative) video on one CD - nothing can even come close.

The way things go , playing on a computer is the only option for these codecs...
