Reader D. J. (who may or may not be a DJ) would like to muck with his videos without demuxing with his videos. He writes
I’m trying to figure out how to transfer the .vob files from a burned DVD into an editing/DVD authoring program without having to demux, recompress, etc. First, I transfer my home videos to DVD using a DVD recorder. Then, I’d like to be able to edit the .vob files to cut out unnecessary footage. I’ve tried with DVD Studio Pro without any luck.
I’d go about it this way.
Download a copy of Squared 5’s free
MPEG Streamclip (available as a Universal Binary). In order to work with .vob you’ll need Apple’s $20
QuickTime MPEG-2 Playback Component. (If you have Final Cut Pro or DVD Studio Pro the MPEG-2 Playback Component is already on your Mac—it’s included with these programs.)
Drag the .vob file into MPEG Streamclip. If there are additional .vob files associated with the one you’ve dragged into the program, you’ll be asked if you’d like to import all the parts of your movie. Yes, you would.
Once in MPEG Streamclip use the Cut, Paste, and Trim commands to edit your video. Once it’s edited to your satisfaction, choose File > Save As, and save your edited file as a new .vob file (or, if you like, export it to another format such as a standard QuickTime movie, DV, AVI, or MPEG-4). iDVD and DVD Studio Pro won’t take the file but Roxio’s Toast will. Burn it in Toast and you’re good to go.
