    Hardware blues

    i am having p4 2GHZ overclocked to 2.665. my average encoding (x264) rate in virtualdub is about 7.9 fps (thats about 2 hour for a 30 min video). i use the deinterlace, resize (lanczos3) & HSV filter while encoding and also make audiostream mp3. is there any configuration where i can get at least 15-20 fps encoding rate (or faster)?? (i am using pc266 ram, is this a problem?)

    you could disable/lower some quality options (like partition decision quality, lowering max ref frames, 8x8 DCT, etc) , or even the HSV filter (brightness/contrast/saturation can be adjusted during playback)

    OR

    the bottleneck it seems is the CPU. you'll need something faster, preferably a dual-core (currently ~50% increase compared to single-core equivalent). faster ram would increase it too.

      How much ram might be critical if you don't have at least 512 megs.

        also, is there a particular reason you wish to do this? x264 is slow, period. its understandable too, considering the output quality.

        its probably out of the question (it definitely is, for my encodes), but lowering output resolution will also speed things up...
