  1. I was talking to a guy about convert my avi’s to mpeg2’s at 8000 bitrate. He said that might not be compatible with every ones stand alone dvd players. So what is standard bitrate for dvd players?

    8000 is fine .... unless you are using PCM audio files - then 7400 is used as max for video ..

    though dvd can of course play higher than this bitrate -- there is an issue with some media (and spikes in some encoders) ..

    As long as you don't go over 8000kbps for the video then you should be A-OK but if you use LPCM audio then you might want to lower the video bitrate just a wee bit ... like maybe 7800kbps since the combined bitrate of 8000bkps video and 1536kbps LPCM audio is a bit close to the MAX total bitrate a DVD can handle.

    If you use AC-3 audio then there is no need to go over 256kbps (at least for 2 channel mono and/or stereo audio) so 8000kbps VIDEO should be fine then.

    Remember that a DVD-R or DVD+R is "harder" to read than a studio made "pressed" DVD disc so that is one reason why you don't want to "push" the bitrate too close to the MAX

    Sorry I posted my first remark without seeing your remark (I took that long to post it because when I first loaded this post there were no responses).

    Anyways I've heard of keeping the VIDEO under 8000kbps when using LPCM audio by selecting a bitrate slightly lower than 8000kbps because even with CBR the bitrate can dip up and down a bit but doesn't 7400kbps sound a bit too low?

    7400 video
    +1536 lpcm
    +25 multiplex overhead
    =8961

    combined i would still suggest to stay under 9000 . even on some some machines/encoder/media combinations - this may be to high and 7000 may be even a safer bet ... but i would try 7400 first (8200 max bit rate though in such case if using VBR, not 9000)


    anyway -- just my opinion ... results will differ ..

    It also depends on the player and the encoder that made the Mpeg. Some encoders vary the bitrate by quite a bit. Some players can handle higher bitrates than others.

    I made a Football video for my son's team last year. Then I distributed it to all the parents. I had Main Concept encode it @ 8400 kbps average - 9000 Max - 4500 Minimum. I also used AC3 @ 224 kbps. The videos played perfectly on everybodys player but one. When I went back and checked the bitrate with a bitrate viewer, it had spiked up to 10024 kbps in some places.

    It seems that when the high bitrate spike came, it would kick the video into the next chapter when it was played on her RCA player. It played perfectly on at least 25 other players though.
