  • TMPGEnc "sweet spots"

    I've been doing some performance testing of TMPGENc.

    CQ mode at 75
    Field A
    MPEG level II audio 224kbps

    slowest 702sec 57433kb
    slow 450sec 36% faster 60001kb 4.5% larger
    normal 347sec 51% faster 61487kb 7.1% larger
    fast 279sec 60% faster 64323kb 12.0% larger
    fastest 259sec 63% faster 71983kb 25.3% larger


    The interesting thing is that the file size becomes larger as the speed decreases. I am thinking that perhaps in order to keep the CQ75 equal for all motion search speeds that the file size increases to offset lessened motion search?

    Anyway, if you need the best quality for the file size go with slowest, slow and normal are all very good, being much faster with only a little larger file size. Finally, stay away from fast and fastest, not much speed improvement and the file size starts to grow like mad, especially at the fastest setting.

    For the record, I used the rendered DV test file from my MSP7 benchmark site. My system is a P4 2.4B 533fsb.

    Finally, I'm having a bit of a problem with TMPGEnc, every time a render finishes the program closes. I can't seem to find a setting to turn this action off in any menu. ???

    Have you done comparisons between TMPGEnc and MPEG.now (as in MSP7)?

    I burned a DVD with the same ~12 min sequence of clips with each @ CBR6000 and VBR6000 average, containing still scenes and fast movement. Viewed on a TV, neither my wife nor I could really discern any notable difference in viewing quality, although comparisons are difficult played sequentially. Viewed frame by frame on a 'puter, there were slight differences on the fast moving clips betweeb CBR and VBR but little between the two makes. What is your experience, if any?

      Brian,

      I am doing some comparisons but am not quite finished.
      Preliminary data shows MSP7 to be faster, but it does take a big hit if you use nonsquare rendering.

      I'll get back on this later...
