I encoded a short movie using all three codecs with an resolution of 720*400 and 25fps.

I must say, that Sorenson Video 3 was the most impressive of all. With 50 % you get a quality which comes close to DVD except for black surfaces, maybe. The movie still looks great at full screen size. 3ivx and OpenDivx didn't do a very great job on my Pismo 500. I have the impression, that both still ned development.

With Sorenson at half the screen resolution you come down to approx. 3.2 MByte per min (720: 8.5 MByte per min), what is as low as 3ivx or DivX. But I don't care about the additional necessary drive space...

Could you please let us know your settings at 720 and half screen resolution?

Assuming you have the SV3 dev edition and Media Cleaner, have you
been able to use the 2-pass VBR? I've been getting great results without it, but I was wondering why it wasn't selectable in Cleaner.

3IVX isn't too bad. The $10 personal edition with artifact reduction is a steal for those who need a good low bit rate codec, but can't budget SV3.

Settings of Sorenson Video 3 at both resolutions:

50 %, 25 fps, key frame none, no bit rate restrictions - no other settings available, I use the codec which comes with QT 5.0.2. The eoncoding was done with MacMPEG2Decoder, latest version.

I also tried 75 % in quality, but the improvement (not very significant and framdrops when there is lotta movement) is not worth the data increase to 25 MByte per min.

3ivX: I use the free codec, Delta 3.5, quality set to 52 %. The quality was comparable to SV3 with half screen resolution expanded to desktop size. However in this case the file size is almost the same. Besides, 3ivX behaves a little bit strange in playback in QT on a Pismo 500, especially in the beginning. It is not as bad as it used to be with earlier versions (I have posted about this before), but SV3 behaves absolutely flawless.

was SV3 encoding slower or faster than 3ivx? and by how much

Thanks,

Encoding time:

With the lower resolution definitely not. However I did not take times, as I was concentrating on the quality. But I will measure as soon as I find time to.
