Hello I am wondering not sure if this is possble or not

I have captured some baseball games from the tv (for my own personal use by the way) they are in mpeg 2 format. I have noticed on tape when it plays that tracking of the picture is difficult to fine tune, its mainly the bottom part of the screen that is really noticeable. The vcr has been cleaned and checked so I assuming its just the video itself.

What I would like to know if there is a way I can crop out or remove that area of the picture that is distorted and jumpy.

Thanks

For most of my cropping i use Nero recode 2 but it will come out as a MPEG-4 file.

Thanks for that I have Nero installed on my computer so will have a go at that program. Does it re-encode the file though? if so I don't really want to lose any of the quality. I have not really used Mpeg4 yet is it the same as Mpeg2?

Appreciate your help thanks

recode 2 has high quality options of transcoding.
i don't know if there is any other cropper.
i've heard of TMPG though

Your problem is going to be that MPEG2 does not re-encode well. TMPGEnc has cropping options but I am almost positive that it will re-encode. I think once you edit the original frame then you have to re-encode to compensate for each frame having a new dimension.

The curling/distortion effect you are seeing on the VHS tape is caused by the tape and head contact not being 100%. This area of the picture is not seen on your TV screen as it is in the overscan area. Dont crop anything from your capture just go ahead and make your DVD your finished product will playback just fine. Sometimes the distortion appears on the side of your captured picture too, but the same thing applies it to is in the overscan area and is not seen on your TV.

If he's getting it though during playback on the VCR then it will show up on the DVD also (past over scan area). Probably the problem is that the original tape was made using an inferior VCR with heads that were misaligned. You could try some of the high end JVC VCRs (HR-S9 series) to see if it helps.
