Replacing 10 seconds of a DVD video

[jmbattle]

Good evening,

I wish to replace 10 seconds or so of footage from a DVD video.
The segment in question contains old information, however I do not have access to the original footage from which the DVD was mastered.

The DVD is a 20min factory tour, consisting of a basic menu interface to select language tracks.

This is what I have achieved so far (using freely available software):

1. Copied DVD contents to harddrive
2. Used StreamRipper to extract the scene to a single vob
3. Demuxed vob, outputting just mpv
3. Converted vob segment to avi using VirtualDub-MPEG2
4. Edited uncompressed avi using Premiere 6 (trial)
5. Converted avi segment back to mpv using TmpegENC
6. Cut beginning of original mpv to the insert point
7. Cut end of original mpv to the 'outsert' point
8. Joined the original beginning, edited middle, and original ending mpv files together

So, now I have a 20min edited mpv file, it plays smoothly, there are no visible joins or cuts and really, I doubt anyone could tell the file has been manually edited.

What I would like to do now is replace the original video track of the DVD with this modified version, but retain the original menus and of course all the original soundtrack data.

I have experimented with DVD Shrink, however I doubt this is capable of what I wish to achieve. I can open the contents of the DVD, am presented with a tree of the menus and video data (showing the audio tracks), however there does not appear to be any functionality to replace just the video track.

Is it possible to replace the video track using free/trial software?

Thank you in advance for any suggestions.

Kind regards,
James

Hi-

Is it possible to replace the video track using free/trial software?

Yes, easily, but you'll have to demux the audio as well. Among other ways, since you have the Vob on the hard drive, open it in DGIndex and go File->Save Project. It'll demux the audio by default. Open the video in Muxman. You could have joined the 3 parts in the new screen that opens, but since the video is already joined together, just Close it. Add the Audio to Audio1. Close the new screen. Add the chapters (if any) in File->Import Chapter. Give it a Destination Folder and hit Start. The result will be a DVD without menus.

Now, open the original unedited DVD - the one with menus - in VobBlanker. Highlight the video to make it appear in the lower screen. Highlight it in the lower screen, hit the "Replace" button to the right, and scroll to your new and edited DVD. Give it an Output Folder, Process, test and burn.

Demultiplex the audio tracks (PGCDemux, if you don't have another software). Author a new DVD with the edited mpv and the demuxed audio tracks using muxman. You need to put them in the same order as they were in the original dvd (and asign them the same audio attributes - language).
Using the replace function of vobblanker replace the vobs in the original dvd with the edited from the newly created. Test with DVD player. Burn to a new disc with Imgburn.
Ha, too late

Thanks chaps, what a tremendous bunch you are!

Yes, given that the DVD is rather basic, I was thinking about simply re-authoring it using my own language menu.

I have just been informed by my boss that there are a number of other edits that need to be performed also. I wonder if there is an easier way of replacing the edited mpeg video segments directly, rather than making lots of split files and joining everything back together manually?

Thanks again,
James
