Useless? Perhaps from an academic standpoint. Some of us are also interested in what we'll see when actually watching a video in real life.
I finally got done ripping my first DVD into h264. Handbrake worked flawlessly except for taking over 24 hours on my dual 1.4 (100mhz bus). It averaged around 10fps for quite a while and then 5fps for the rest of the rip. Sorry, I wasn't paying attention to which 'stage' was what and how long each took.
The image, as noted earlier, turned out a bit dark for viewing on my computer's display. However, when piped through a television, the gama levels seemed to be spot on. There were no visible artifacts even when the DVD was compressed down to 700megs with 5.1 aac128 audio.
Playback is quite processor intensive at 720x400, eating up around half of each CPU. Scrubing is also much slower, resulting in a two second lag when jumping to another spot in the film.
One nice thing about QT7 (and the new dvd player) is that live resizing actually works. Although it isn't glass smooth when playing back h264 at this size on my computer, it is amazingly fast. I'm unsure what the iChat preview window is displayed in but it resizes absolutely flawlessly.
In particular, i noticed less banding, blocking, and color artifacts as compared to a similar divx rip. It looks like divx and h264 have enough followers and active developement to result in some really great competition over the next few years.
