    I am presenting a short video next month. The player that will be used is a WD TV that feeds into a 720P projector. I intend to create an MP4 file with the H.264 codec and use a USB hard disc to plug into the WD TV.. I would like to know the recommended maximum bitrate and reframes that won't "choke" the WD-TV.

  2. With firmware 1.01.01 (and above), the performance is improved:

    Normal HD resolutions:
    x-1920 Y-800-832@8rf ; 848-928@7rf ; 944-1024@6rf ; 1040-1080@5rf
    x-1440 Y-800-832@11rf 848-896@10rf ; 912-960@9rf ; 976-1056@8rf ; 1072-1080@7rf
    x-1280 : all 720p labeled videos are fully compatible
    ...
    Shizzzon also tested different H.264 Profile Levels, but found no limitations in the WD TV.
    From http://wdtv.wetpaint.com/page/H.264+reference+frames+specs. More than 4 reference frames won't help on most video anyway, except animation.

    There appear to be no bitrate limitations stated. You should have no problems at all with 720p, but if you want to be absolutely sure, you may choose to set the --vbv options to something like 24000.

    I'm not too sure what the maximum bit rate would be, but I'm guessing an untouched video stream from any bluray wouldn't be a problem....I took a few m2ts files straight from a bluray without encoding (just demuxed straight from the disc) and was able to play them perfectly (1080p, 23.8 Mbps bitrate).

    this is on a wd tv with the 1.02.07 firmware.

    Hmm, just a thought, but I wonder if the USB might end up being the limiting factor, not the WD TV. In other words, if the WD TV is fine with 24 Mbps files, the speed of your USB device might be what slows you down (depending on how well that USB device actually works - they don't always get up to their theoretical max speed, in my experience.) Of course if you're copying your video file from a USB device onto some sort of hard drive or something then this wouldn't be an issue. Might not end up being an issue, just something to think about.
