creating a black bar in the bottom

[GGuyZ]

Hi everyone.

How can I create a black bar in Vdub that will not resize the video, but instead come over some of the footage(for an instance the lower 16 pixels).

1) Load the .AVI into VirtualDub (or one of its variants)
2) Set "Audio" to "Direct Stream Copying"
3) Set "Video" to "Full Processing Mode"
4) From under the "Video" dropdown menu, select "Compression" and select the same codec and settings that were used for the original .AVI
5) From under the "Video" dropdown menu, select "Filters"
6) Click on the "Add" radio button
7) Doubleclick on the "Null transform" filter
8) Click on the "Cropping" radio button
9) Enter the proper amount in the "Y2 offset" (at lower left) to cut off the subtitles or whatever you're trying to eliminate.
10) Click on "OK"
11) Click on the "Add" radio button
12) Doubleclick on the "Resize" filter
13) Under "New width and height" enter the NEW dimensions of your cropped video (e.g. 720x440)
14) Select "Precise bicubic"
15) Put a checkmark in "Expand frame and letterbox image"
16) Set "frame width" and "frame height" to the ORIGINAL dimensions (e.g. 720x480)
17) Click on "OK" (brings you back to primary "Filters" screen" and then click on "OK" (to get back to main VirtualDub screen)
18) From the "File" dropdown menu, select "Save AVI" and save with a NEW filename

Let us know of your success ;>}

Thank you so much :)

I see that one of the filters that need to be used is "Resize". But as far as I see it's only for adding the black bar so the original footage isn't resized?

Regarding "Direct stream copy" for the audio - all I can see is one option for stream type. Maybe this is because I am using Vdubmod?
But I am probably going to strip out the audio and reencode it to AC3 so it doesn't really matter.

One last thing - If I'm using an interlaced source, should I unfold the fields before performing those filters, or no?

EDIT: Precise bicubic has a few options. which one of them is suitable for me? a=-0.75, or -0.60, or -1?
It seems that the image is being centered after the process, and there's a small black bar created at the top as well as the bottom. Is there anything to be done about this?

Maybe this is because I am using Vdubmod?Yes...
