Easy question:

If I have a standalone burner like a Pioneer or similar can I burn to a DVD-RW and take this disc to a computer and watch the files and manipulate???? What are the limits???

Thanks

You can watch the disc, but you can't manipuate. At least not without doing some serious decoding.

The files that are on the DVD are not standard Mpeg2 files, but VOB-files. VOB's contain the video in Mpeg2-format, but also sound (in various format's), subtitling etc. Unfortunately, you can't edit VOB-files in video editing programs directly (at least not as far as i know). You'd first have to convert it back to an editable format like AVI. There are programs that can do this, but in doing all this you're taking the long way home. Possible, but you're wasting a lot of time. If you want to edit your video than try to transfer it to PC directly, which will give you an editable format immediately. From there you can create a disc.

Hope this is clear.

Thanks Den

I think I need to feed my cable into my PC (capture card)and capture it like this. Then I should be able to manipulate it.

learn the file format and layout of a DVD, then find a MPEG2 editing program (like Womble MPEG Video Wizard) and manipulate the files from there. This will result in minimal loss of quality (if any at all).

If you are simply trying to go from DVD to a format that can be shared on the web then the capture card would be okay as you have to reduce quality anyway.

Thumperxr69,

It depends on what kind of capture card you're using. What's your source? Is it a digital cam? If it is at all possible to use a firewire connection between a cam and PC you will have no quality loss. If you're capturing an analog signal, that's a different story altogether (depending on the quality of the signal, the capture card etc..).

sivartk,

I have to disagree with you. MPEG2 is already a heavily coded (and thus lower in quality), and much more difficult to manipulate/edit than say an AVI-file. It's not wise to take an MPEG2, decode it to AVI, and then recode it to MPEG2. You will loose quality because of the decoding/encoding process, unless you're sure your MPEG2 encoder (and your use of it) is as good as the one your source was created with.

Also, the file format of DVD has very little to do with MPEG2, a lot more information is present in the DVD file format. It's not as easy as you make it out to be.

I guess maybe it just appears easy to me, here is what I can do with no quality loss -- i.e. no re-encoding.

1) Copy .vob files that I want from DVD drive to hard drive

2) Open these files in MPEG DVD Video Wizard

3) Cut the areas out that I want gone

4) "Stream Copy" (I.e. no loss) my final project to an .mpg file

5) Use TMPGEnc DVD Author to author new disc (no re-encoding).

Have been doing this with several TV shows and can't tell a difference between the original and the final version on my PC at a resolution of 1280x1024 full screen.

But in the end, do what is easiest for you and gives you quality you like.

I've used womble to edit the vob files on disks recorded on my Sony RDR-GX7 DVD recorder, then saved them as mpeg 2's with no re-encoding or problems.

Thanks Ioan That's exactly the information I was looking for...
