Trim captured file

[psigna]

I captured a file from VHS to my computer. On the bottom of the screen is a bit of tracking, probably due to the old tape. Is there a way to cut this portion from the entire file, perhaps make it a slight bit shorter, vertically? The Tracking is all along the bottom edge of the file playback. I used Windvd creator 2 to capture and TMNGE dvd author to create the dvd files and burn. I still have the authored file as well as the raw captured file on my computer.

If the raw file is avi, use virtualdub to crop it, and frameserve to tmpgenc to encode if possible. Or save it as uncompressed avi (beware, HUGE file size), or maybe try a good lossless codec like Huffyuv or Lagarith.

I've seen the same thing on some VHS transfers (DV passthrough) but then it doesn't show up after I burn the DVD. Try burning one first.

Here's the thing.

That part of the image usually ends up in the overscan area of the TV (that part that you can't see off the edges of the screen). So you don't see it, but it's there.

The problem is that it eats bits like crazy, wasting the available bandwidth that could be used by the rest of the video. Therefore, it also significantly reduces the compressability of the video (which also affects the quality).

It is an mpeg file created by Windvd creator2. Is there something like virtual dub that can be used for this file?

Virtualdubmod.

This line will end up beeing invisible on your TV so just ignore it if everything else is OK. You can only see it on your PC. It is there when you play VHS on your TV but you don't see it, do you? TV overscan will hide it for you.

tmpgenc used to have a "crop" filter (in the old 2.5 version anyway).

The standalone Mainconcept encoder has a crop feature also -- so you could just get rid of it during the encoding process.

I do this when I know some viewers will be watching the video on their PC (as well as their TV). For the PC viewers, I like to get rid of that garbled line...

Also, if you create autorun cd's with tools like mmb, it has a "mask" feature that can be used to just "hide" that line during playback (so no re-encoding or cropping is needed).

I played it on the TV and it does not show. Now I just have to get rid of the flickering. Thanks a bunch.
