Crap at the bottom of the screen

[clothesburner626]

When I go from video to the computer, no matter which capturing program I use, there's always "this crap" down at the bottom of the screen. How do I make it so that "the crap" is not visible when playing from DVD?

Its over scan it will be gone when you play it on the TV.

Just burnt my first dvd tonight, didn't even realize it was gone. Thanks!

clothesburner626,

I'd suggest to overlay this crap, because it wastes your bandwidth when encoding. I use AviSynth's Letterbox() function to get rid of it.

Qute from AviSynth docs:

Letterbox (clip, int top, int bottom, [int left], [int right], int "color")

Letterbox simply blackens out the top top and the bottom bottom, and optinally left and right side of each frame. This has a couple of uses: one, it can eliminate stray video noise from the existing black bands in an image that's already letterboxed; two, it can eliminate the garbage lines that often appear at the bottom of the frame in captures from VHS tape.

The functionality of Letterbox can be duplicated with a combination of Crop and AddBorders, but Letterbox is faster and easier.

Generally, it's better to crop this stuff off using Crop or CropBottom than to hide it with Letterbox. However, in some cases, particularly if you're compressing to MPEG, it's better to use Letterbox because it lets you keep a standard frame size like 352x288 or 320x240. Some MPEG players get confused when the source video has a strange frame size.

Another use could also be to clear out overscan areas in VCD or SVCD encodings.

Question #1: Send the edited AVI file to Letterbox or the mpeg?

#2: Is it freeware?

1) AVI -> AviSynth Letterbox -> mpeg encoder -> mpg
2) yes

I think that the crap at the bottom is information used by the VCR for things like audio sync etc.. (although I really am not an expert on this).

The others are right that you wouldn't usually see this because of overscan on TV's - it would be hidden just off-screen.

It's a good idea to get rid of it before encoding to save bandwidth for what is visible.

AviSynth is very good, and a lot more simple than it seems at first, but another alternative is VirtualDub - which is also freeware, and arguably a bit easier to set up.

You can frameserve from VirtualDub into some MPEG/DVD encoders, such as TMPGEnc Plus. There are guides aplenty about how to do this on the left.
