Getting rid of borders

[peter p]

I can't seem to get rid of the top and bottom borders when I convert from avi to svcd with DVD2SVCD no matter what aspect ratio I use and even changing the setings on the DVD player won't remove them.
My movie that I am converting has a resolution of 720 x 304 and I am resizing to "SVCD 480x480/576" in the "Framesaver" section.
If I set the "Resize to" setting to "DVD 720x480\576" and preview the video before converting by pressing "preview video (still picture)", the borders disapear. Will this setting, (DVD 720x480\576) remove the borders and still give me good picture quality or is there another setting that I have to change to get rid of the borders?

Thanks.

I don't know much about the workings of DVD2SVCD, but you could always resize the video outside of that tool, using for example, virtualdub. The problem thne will be that you will lose the original Display Aspect Ratio. SVCD does not support 16:9 DAR, so it will always encode as 4:3. In order to maintain the DAR of the original, the black borders are added. If you don't do this, everthing will look squashed horizonatlly and people will look tall and skinny. Is that what you want?

Can't I remove the borders with avisynth and still get wide screen?
I need to know how to remove the borders by changing the avisynth script file.

1) SVCD does not support 16:9. The best you can do is encode it as 4:3 and then have your DVD player/TV stretch it to 16:9 (assuming you have a wide screen TV)

2) Widescreen is 16:9 or 1.76:1, your avi is 2.36:1, so if you remove the black borders and stretch it to fit a 16:9 screen, the AR will be screwed up.

I converted another movie and for some reason I had a border around the left and right side. I then changed the avisynth script file to "^b= 0.33
and ^c= 0.33" something like that. I read LeeBear's article on how to do it and that removed the left and right borders but had no borders at the top. The movie fit my whole TV screen
The second movie I converted has borders at the top and bottom with the same settings.
My TV is a widescreen and I can change the settings from wide screen to letterbox to PS??? but that still doesn't remove the borders. On a original DVD movie, changing the widescreen setting removes the borders.
I don't know why one movie has borders with the settings and the other one dosen't.

I don't know why one movie has borders with the settings and the other one dosen't.

Because they are different Aspect ratios.

If you have a 4:3 TV and play a wide screen movie you have the choice of letterboxing, so it displays with black borders top and bottom, or filling the screen which the player does by zooming in on the middle of the picture, chopping off the sides. Even when you do this some movies shot in aspect ratios wider than 16:9 still leave (smallish) borders top and bottom.

My mistake,
my TV is wide screen.

Whatever TV you have, some movies are even 'wider' aspect ratio than a widescreen TV, so you still get balck bars top and bottom, unless you want to screw up the aspect ratio.

what i do in cases like this is get a piece of paper, and write down the original frame size (720 x 304)

i like to work in pal as i'm in pal country. and avi is usually in 1:1 par and dar. So i convert the above frame size to see what it would be in a 768 x 576 container.

720 x 304 (1:1) (1:1)
=768 x 324 (1:1) (but in 768 x 576 frame size)
= 720 x 324 (4:3 in 720 x 576 dvd compliant frame size.
= 480 x 324 (4:3 in svcd frame size)

(576 - 324)/2 = 126 hence, you need to add 126 pixels to top and bottom, to keep the same aspect ratio of the original.

you will see this, by doing resize filter in virtual dub, to 480 x 324, and then expand frame and letterbox image to 480 x 576.

on the output pane, you right click and select 4:3 display ratio. YOu will see, that both panes have the same proportions now.

wheres the output pane in VD?

[peter p]

Ok, I got it. My version was older and for some reason the output preview pane didn't show properly.
