    Hi

    I converted at 320mb video file to mpeg and got a 100mb file that will not display sound or video.

    The setting I used were - MPEG-2 512x384 23.976fps VBR 1150kbps, Layer-2 44100Hz 192kbps.

    any ideas folks.

    Well one thing I can spot staight away...your resolution is incorrect for vcd (as your creating an mpeg1)

    Pal (25fps) = 352 x 288
    Ntsc/Film (29 or 23.976) = 352 x 240

    Also your Bitrate should be cbr (constant 1150)
    NOT vbr (variable 1150)

    And if were being REALLY picky :eek:)

    Your audio should be 224kbs not 192 (but this rearly makes a difference)

    Are you going for vcd or svcd as i noticed you say mpeg2 in the first post but mpeg1 in the second ?

    Regards Acheron

    Ah ye, I didnt even check that out at all, lol

    The reason for that is, TMPGEnc takes the frame size of the source video when it is loaded in, in fact i better add that to the TMPGEnc problems thread.

    As for audio 192kb/s is actually standard even though nero might tell you otherwise!

    Nope 224 kbs @ 44.1 khz is the audio standard for vcd.. :eek:)

    Edit: I just checked were both wrong & right

    Vcd 1.1 spec is: 224 kbit/sec
    Vcd 2.0 spec is: 128,192,224 or 384(!) kbit/sec

    All at 16 bit,44.1k Sampling rate. :eek:)

    lol, well there is no point in going higher than 224kb/s on VCD cause it sucks video quality anyway!
