I bought myself a DVD "Das Boot", and while the movie itself is great, the way it is presented is awful. Here's the example
pic 1 http://www.imagecabin.com/files/2006/10/24/thumbs/16171514013c6cc4867e89689.jpg (http://www.imagecabin.com/?view=16171514013c6cc4867e89689) pic 2 http://www.imagecabin.com/files/2006/10/24/thumbs/161715140ce725318499c186e.jpg (http://www.imagecabin.com/?view=161715140ce725318499c186e)
The first 20 chapters have this big black bar only on the right side (pic 1), all other 46 chapters have smaller black bar on both sides (pic 2), which makes viewing more pleasant (to me at least). Now comes the question, is it possible to move/slide video to the right and add black bar on the left side (even it up)?
One more question. Is there a program which can give info about max/min/ave bitrate of a DVD?
thnx

1) What you need to do is to crop those black bars. Some part of the picture information in the normal frames will have to be overcropped in order to get rid of those black bars in the badly authored frames completely. If you don't want to lose picture information, leave the bars as is. Once cropped, if your target is a DVD, then you can readd proper even bars with the AddBorders(..) function of Avisynth. Cropping will require reencoding.

2) Bitrate Viewer (http://teco.emg.hu/bitratev/BV.EXE) or DVD Bitrate Viewer (http://www.videohelp.com/download/bitrate14.exe) or DGIndex when previewing and/or saving the project.

Hi-

About the first question, evening the amount of black to both sides. Say the first 20 chapters end at frame #100000, and say there's 16 pixels of black on the right side of the picture that you want to distribute evenly to both sides, and say after chapter 20 everything's fine, then:

A=Trim(0,99999).Crop(0,0,-16,0).AddBorders(8,0,8,0)
B=Trim(100000,0)#nothing happens
A+B

Adjust for the real frame numbers and the true amount of black to be redistributed.

And as unskinnyboy said, fixing it requires a full reencode.
