How do you add black bars on the top & bottom

[duceyaj]

i have a widescreen video and i want to add the black bars so i can make it a vcd compliant video. the resolution of the video is 576 x 336 @ 25 fps

any help is greatly appreciated

use virtualdub
open video sorce
under video tab, click filters
on filters screen, click add
on add filter screen, select resize and then click o.k.

(the following is based on your info)
on filter resize window-
new width=352
new height=205
check the "expand frame and letterbox image" box
frame width=352
frame height=288
make sure color is black

If you're using TMPGEnc, you can just feed it the 576x336 stream, define the source aspect ratio as 1:1 (leave the resulting MPEG ratio at 3:4!), keep aspect ratio and let TMPGEnc resize and add the borders.

how do i change it to svcd instead of regular vcd?
I think I'd prefer PAL format because of the 25fps.

when i try doing what you've just said, it gives me this error: (Index of scan is out of range(336)



btw, the file i'm trying to convert is from a divx 4 file.

Hmm. Strange.

I'm not sure that the 352x205 ratio is right either - it indeed preserves the aspect ratio of the original, but doesn't take into account that 352x288 isn't using 1:1 pixel aspect ratio.

In that case I'll do:

• First, use the resize filter, without resizing and just expand the video frame to 576x432. This will give you a 4:3 frame (including black bars) using a 1:1 pixel aspect ratio, just as the original file
• Then, add another resize filter, using precize bicubic, to make the overall frame fit a 480x576 frame

I might be wrong, corrections are more than welcome.
