What is DVD Ready "VOB" Format mpeg2 vs Other? mpeg2

Feb 12, 2013 1:49 PM

I have Premiere Elements 9 and am working with Sony Handycam files which GSpot identifies as DVD Ready "VOB" Format and I have looked high and low for what that means. I also have some progressive scan mpeg's which i may be using later.

I am sure you guys have been around this long enough that it's common knowledge for you, but what makes one type of mpeg2 more dvd ready than another and which ones need to be converted first before bringing into a project? I know the program will convert some to avi

    VOBs are a form of MPEG2. They have certain parameters that make them DVD ready, however --  720x480 resolution, 29.97i frame rate, etc.

     

    You can change a VOBs suffix to .mpg and it will still be the same file. An mpeg. The .vob suffix just identifies as a DVD file.

     

    You're not really clear what you're trying to do with this fil. But, if you're planning to use DVD files or even standard definition MPEGs, make sure your project is properly set up for them or you're not going to get good results.

     

    Likewise, if your "progressive scan MPEGs" are not 720x480 resolution, you may want to proceed cautiously. Prior to version 11, the program did not handle a mix of formats or resolutions well.

    As I said, it's basically its resolution, frame rate and bit rate.

     

    There may be something else. The Wikipedia article does a great job going into more detail.

    http://en.wikipedia.org/wiki/VOB

     

    The main point is that all VOBs are MPEG2s -- but not all MPEG2s are VOBs.

    Besides the acutal MPEG-2 DVD, inside the VOB container, and the Wiki article, this article goes into some detail on VOB's, and what can be inside them: http://forums.adobe.com/message/2298534#2298534

     

    Besides the MPEG-2 format, there are other DVD considerations, such as the Bit-Rate. Also, the Audio can be PCM/WAV, or DD AC3 - it just depends.

     

    Good luck,

    You can import them as they are, however you need to choose the widescreen preset from the Hard Disk folder and not the DV folder,

    as you footage is upper fields first (TFF).
