Converting from VOB to any other format - doesn't keep the original size

[Mylo]

I'm confused right now

OK - here's the breakdown, I'll illustrate it here because I know I won't describe it good enough by words.

So this is the case;

I took a 10 second clip from one DVD movie with DVD Shrink. I got the VOB file.


When I preview it in MPC - it looks like this (white part is the video part);

When I save the image frame via MPC - it looks like this;

and the image is squeezed

And when I go to Vegas - and when I convert video to WMV, with pixel ratio 1:1 and keeping the original size (720 576), this is what I get;

Why does it get smaller even when I kept the same video size while converting to WMV?

It looks like Vegas is resizing the 16:9 anamorphic image(the squeezed image) to non-anamorphic in 720x576 . I don't use Vegas so I have no idea if you can adjust that, maybe just change the output to 16:9.

But what is your goal? I would crop the black borders and resize the image size to 16:9 size like 720x406 or similar as it mostly works better instead of having wmv video with 16:9 display aspect ratio.

I got it working.

But what still confuses me is....why does it say in MPC properties of that VOB file that it's 720x576

When it CLEARLY takes up the whole width of my screen which is 1024

And in MPC if I zoom out one step (numpad 1) I can see the borders of the video shrinking ....


.. and the zoom going from 1.00 down...

So why does it say it's 720x576?

You have a ~2.35:1 movie on a 16:9 (1.78:1) DVD. PAL DVD always uses a 720x576 frame -- both for 4:3 and 16:9 material. The final shape of the picture is determined by a flag that indicates whether the video should be displayed as 4:3 or 16:9 -- the only two display aspect ratios supported by DVD. DVD pixels are not square.

The export from MPC retains the original frame size to give you a pixel-for-pixel image. It did not scale the video to the final display aspect ratio. The black bars are part of the 720x576 DVD source (because the movie is wider than 16:9).

It looks like Vegas scaled the video to a ~720x406 to maintain the proper 16:9 aspect ratio with square pixels. Then added black bars to the top and bottom to fill out the 720x576 frame. Which is exactly what you asked it to do.

That is your software player doing that. The original video has not been altered. The player is fitting the video to the screen. You can do that to a cell phone video clip smaller than 320x240. It won't magically be upconverted to 1024 but the player makes it fit your monitor so you can see it larger. Also note that the larger the jump from the original video size the poorer the quality of the video is usually - depending on the source and how good your player/monitor is on upscaling of course.

On the other hand, a 16:9 720x576 PAL DVD does get resized to 1024x576 at playback time. No scaling to fit the width of his screen.
