    MPEG-1/VCD vs. MPEG-2

    Posted by Jason Connolly on July 14, 2008 at 4:19 pm

    Greetings!

    I have a client who has asked me to convert a SD digibeta to the following spec:

    Video Format: MPEG-1/VCD
    Stream: MPEG-2 Program Stream w/ elementary video/audio streams
    Bitrate: 2.8 – 3.5 Mb/sec
    Resolution: 640×480
    Aspect: 4:3
    Rate: 29.97
    Chroma: 4:2:0
    GOP Length: 15
    GOP Structure: IBBPBBPBBPBBPBBPBB
    GOP Type: closed

    My question: doesn’t MPEG-1 and MPEG-2 conflict with one another?? I don’t understand why the format is MPEG-1 and the stream is MPEG-2? It would seem that the specs suggest that they are looking for a MPEG-2 file, yes?

    Any feedback welcome!
    Thanks!
    Jason

    Looks to me like someone is giving specs without knowing what they are talking about. I would guess looking at the MPG2 specs (which are very low) that they will accept eitehr MPG1/VCD or the MPG2. Not both.
