Hi,

I wanted to see how DivX 5.0 Pro did at low bitrates, so I encoded Robin Hood: Prince of Thieves last night.

Settings were similar to my previous, all new goodies turned on, psycho-babble turned to "normal"

Max quant 12, min 2

Bitrate set to 600kps, 2pass vbr encode

Movie is 2hr, 23min (or 143min) long

Filesize came out to 620meg, no audio

Quality is not bad. Obviously it can't be as good as a two cd-rip, but it is definately better than anything divx 3/4 can do at that low bitrate. Areas where some blocks are visible the blocks are very small, oddly enough that qpel setting must have something to do with this.


In closing, I'd like to say that DivX Pro 5.0 so far has impressed me greatly. Yes, the drawbacks of no file-size prediction whatsoever are critical and need to be addressed, perhaps by the release of a working bitrate calculator? But until the two-pass mode is closer to Nandub's or Xvids, I think that will be a ways off for DivX 5. Right now, the inclusion of b-frame support and obvious functiability at low bitrates has sold me on DiVX 5.0 Pro right now.

Thanks for reading...

I'm not really convinced by DivX5 yet - XviD developes well, often has superior results (especially in external 2-pass mode, using stats files calculated with GKnot); and Koepi just promised a surprise for the next week...
