DVD is mpeg2, and ripping one doesn't mean re-encoding it but "demultiplexing" the VOBs (I don't know if we say that in English). The quality remains exactly the same. You can use YadeX for that.
And we can compare the result to handbrake's H.264 (which uses Mencoder I think, or ffmpeg ?). The same codec does not imply the same image quality. For example, Mencoder's mpeg1-4 is better than ffmpeg's.
Can I ask whether QT7 has better support (ie actually playable) for .avi Xvid files? I swear I read somewhere that it was to have better support for third party codecs or something to that extent.
hmmm... well, I got to work and it was done. Is there any way to see when an applications stopped doing something, like in a log file (and where would it be?)
I'm ripping the movie with Handbrake now at the same specs. Its pretty slow as well but...
Will put comparisons of XVID, QT H.264 encoded, and Handbrake H.264 encoded screenshots asap. Probably end of today or tomorrow. Depends on my workload today.
If you have any requests, tell me now.
PS The movie is going to be a bit dark, Interview With A Vampire. Not sure why I chose this movie. I guess its the first I got my hands on.
I have been ripping Minority Report in Handbrake H.264 overnight. I stared at 9pm last night and when I left the house at 11am it had done 40% of the second pass. I'm using a 1.33GHz PowerBook G4 with 512MB RAM. Compared to Xvid (ffmpeg) encoding it seems to be about half to a third of the speed.
I also have Minority Report as a MP4 Xvid file, which I can post images of if you like. I don't have QT7 though, so I'll be using VLC. Minority Report is 2hr 20min long btw.
PS. Actually saying that, my MP4 Xvid copy of Minority Report plays in QT6. It would appear QT has a problem with .avi files and not the Xvid encoding?

Keep in mind that .avi is a container format, not a particular codec. An avi file could contain one of many different types of audio and video codecs.
There is a divx plugin that allows QT to play avi files containing divx video. It doesn't work perfectly so I tend to use VLC for everything.
HandBrake took 6 hours 15 minutes to encode the same file.
QT took somewhere around 14-18 hours.
No audio encoded, 2-pass, H.264
In few hours should have some screenshot comparisons
Curiosity: Both HandBrake and QT consume about 65-70% of the processors and not 99% like when I encode with HandBrake into Xvid. I dont understand why not.

I found the same thing. Sometimes it went up to 80%, but it was completely the only thing running, even turned Airport and Bluetooth off.
Also, i have just seen that Handbrake can encode 2 streams of audio. I have tried this with the original audio and a commentary and it's brilliant in VLC. I ripped a section in Xvid, but QT6 mixes the two audio streams together. Do you know if there is a way of playing each audio stream separately?
Just tried it out on a chapter of Interview. Using HandBrake and ability to encode two audio streams.
Plays back fine in QT7.
See (PDF) [[taken off just in case. pm me if you want to see. its nothing special though. just a dialog box with option to select tracks of audio or video in a QT movie]]
Problem is, it will play BOTH audio tracks if you dont deactivate one
I was suddenly listening to the clip in English and French at the same time
Just go into Properties (Apple+J) and deactivate the audio track you dont want to listen to.
As you can see, the property window is VASTLY improved. You can rename the tracks and stuff. Great stuff.
PS the screenshot is of a moving scene in the movie (no artifacts!). I forgot to make the pixels size smaller, so its at 1:1 DVD size of 720x400.

That's bloody excellent Much much better options than QT6.
As for the size, would you say there are less artifacts when the rip is at 1:1 size rather than when you scale it down? I personally always rip at the original 720x size.
french macuser: I was running a Xvid rip earlier and on my PB it is about 3 times faster too. ~6fps for H.264 and ~17fps for Xvid.
PS. Also, does the changes to the properties stick when the movie is closed. For example, if you disable the second audio track, will it stay disabled next time the movie is run? And same for if you rename the audio track.
funny you should mention the save thing. I then tried to save the file with a track disabled and simply told me "unable to save". Gonna have to report that. Dammit.

I downloaded Yadex and extracted the VOBs to MPEG2 (.m2v).
QT7 Pro includes the MPEG2 decoders (hurrah) so I didnt have to download the MPEG2 Component.
On a Dual G5 2.5GHz it took well over a minute to open the file (!!).
Also there is no audio. Grr.
Im currently saving as an H.264 file (700MB target size, 890kbit/sec, 2-pass) and its just abysmally slow.
Its been going since 18:00 and its 21:00 now and its at about 1/8th of the way. *sigh* The result better be friggen amazing.
Hmm... maybe I should've just encoded a chapter instead of the whole DVD...
ah well... I'll let it run over night and come in the morning and see where it's at.

QT doesnt support XVID. You may have a plugin that allows you to view it in QT6
Regarding playback, it will be the same if you see H.264 files in VLC or QT7.

That's a 24 hour encoding.
Anyway, quicktime mpeg2 decoding has always sucked. Maybe diva would be faster.

yes (with HandBrake) 99% with both processors = approx 60fps encoding.
when you encode in H.264 both processors are at about 70%
same with QT. Both procs are at about 70%

Xvid must be more optimised for dual processing. On my iBook, Xvid and H.264 use both 100% of my processor. Xvid is rougly 3 times faster.
