Welcome to the forum.
First, editing .VOB's of TV can be easy, or maybe not. It all depends on the exact equipment used, and on the files that it produces. This ARTICLE will give you some background on .VOB's. It all depends on how close to 100% DVD-compliant the resulting files are. PrE will handle files that are 100% DVD-compliant. Otherwise, there will likely be issues.
Now, for your OOS (Out Of Sync) issues, this ARTICLE will tell you how to get things back into, well sync.
I usually use Womble MPEG Video Wizard DVD to do edit simple projects involving MPEG2 files, such as removing ads from a show I recorded or cutting a small clip out from a large segment. If you want to do more extensive editing, you should convert the MPEG2 files into DV-AVI files and edit them in you favourite NLE such as Premiere Elements 7.0.
I agree with Teajay. Convert your DVD video first to DV-AVIs and your workflow will be much less error-prone. The FAQs to the right of this forum tell you how.
If you have tried repeatably and unsuccessfully to rip the VOBs from the DVD-VIDEO on a DVD-R or +RW using the Premiere Elements 7 (Get Media/"DVD (Camcorder or PC DVD Drive), I would strongly suggest that you use MPEG Streamclip to convert to DV AVI. Then bring the DV AVI version into Premiere Elements 7 via Get Media/Files & Folders from the save hard drive location of the DV AVI version.
MPEG Streamclip should take care of quality as well as any audio out of sync issues.
You have two set up choices
Free...MPEG Streamclip + QuickTime Alternative (which contains the required MPEG-2 Playback Component), BUT you need to uninstall your regular QuickTime to get this to work.
Partially Free...MPEG Streamclip + your regular QuickTime + purchase from Apple of the MPEG-2 Playback Component
If you are going to being doing this type of a project on a regular basis, it might be worth the investment of going the partially free route.
Are you in a NTSC or PAL area? If you need a step by step for the MPEG Streamclip route, it will be supplied on request. I use it routinely. It is quick and effective.
(Add on...when ripping VOBs from DVD-VIDEO have you ever tried: (1) placing your DVD in the DVD burner drive tray (2) Premiere Elements 7 Get Media/"DVD (Camcorder or PC DVD Drive) (3) using the Media Downloader to bring your VOBs to the Premiere Elements 7 project? Or, are you doing something else?)
Answer is YES.
but editing DVD (VOB) footage itself a tricky process. Better to convert it to DV-AVI either via Premiere Elements or by some other software otherwise it will take a little more time to edit.
Awsome reply thanks and yes I would be very interested in step by step for the MPEG Streamclip route. I think I have started the process ... thanks again apreciate you taking the time!
Great thanks for taking the time to reply awsome lead!
Here are the details and suggested settings for MPEG Streamclip and its use for converting your video to DV AVI
File Menu/Open, to bring in your video (VIDEO_TS, VOBs)
File Menu/click on "Export to AVI" NOT "Export to DV"
Then in AVI/DivX Exporter dialog:
Compressor: Apple DV PAL or Apple DVCPRO-PAL if your are in a PAL area; Apple DV/DVCPRO-NTSC if you are in a NTSC area.
Put a dot next to 720 x 576 (DV PAL) or 720 x 480 (NTSC), depending on your location
Field Dominance: Lower Field First
Up at top right, click on Options, set there for Aspect Ratio = 16:9 widescreen or 4:3 standard
Only if necessary, put a check mark next to Deinterlace Video.
Anything that I did not mention, leave as is.
Also, if you are in a PAL area, try Apple DV PAL first as Compressor.
Finally, click on Make AVI and the job is done quickly and effectively.
When you get a chance, please let us know if this worked for you.
