QT on new Mac Pros - was: Quicktime 7.6.1

[Steve Freebairn]

Does the Quicktime 7.6.1 update fix the 7.4 issue?

Edit: Ok, I'm a moron, I saw the update and saw 7.6.1 and didn't notice the iTunes on there. Sorry

It'a QT 7.4.1 and it's not recomended.

7.8.2b does the trick.

Here's my updated QT adventure for today...

I've got a new Mac Pro. I can only install OSX 10.5.1 or later on it, which means it gets installed with QT 7.4. That is a problem, so I use Pacifist to clear 7.4 and install 7.3.1. Bad deal... 7.3.1 on this system crashes, hangs, causes all sorts of mayhem. I re-install, repair, etc.. nothing works. 7.3.1 is broken on this system. 7.4 has lots of issues too.

7.3.1 wasn't working, so I updated to 7.4.1. Everything has been running well now for the last couple hours and I've been hitting it pretty hard. The only issue I am having with 7.4.1 is stuttering playback in the QT proxies. But everything else is working. I can output from REDCINE to prores, I can output DPX, Tiff and EXR stills. Playback in REDCINE on this system is buttery smooth too at half res high... I've got a 3TB RAID I'm working off of -- iometer benchmarks it at 218MB/s, which seems pretty good for 3 x 1TB in a RAID-0.

Anyway, this system is pretty quick... I'll do some better benchmark tests with RC and RA after a bit.

So, for right now, 7.3.1 is still probably the best choice if you can run it OK. So far on this new 8-core 3.2GHz w/8800GT, 7.3.1 has been a bad thing.

Edit> why does playback of 4K 2:1 R3D files give be blue frames with frame buffer errors? Seems to be holding about 8fps, but I get blue frames that flash something to the effect of "can't lock image buffer". ???

We've got a brand new MacPro8 3.0 with Nividia 5600 and QT 7.4.1 ( QT 7.3.1 caused many probllems with 5600 and some apps.) and everything is working like a charm, also RedCine.

I spoke too soon... It looks like my ProRes output via REDCINE is hosed, I just get garbled video past frame 1 most of the time. Had REDCINE crash on me 3 times in the past hour.

I don't think it's QT related, but can't get any changes I make on the color panel to transfer through to any form of output. So REDCINE operation on this system are hit or miss. Restarting seems to clear up some of it for a bit, then it starts going screwy.

Eedit> It's difficult sorting out what is a QT bug and what is a problem or bug with REDCINE... Restarting the system and wiping out the REDCINE project directory and starting over fixes most all the problems. All working well again... For the moment.

System is Mac Pro 8-core 3.2GHz, 16GB RAM, 8800GT video, OSX 10.5.2, QT 7.4.1 w/all OS and pro apps updates installed including Leopard graphics update.

So far my new Mac Pro had not crashed (knock on wood). I've exported 2K DPX files out of Red Cine from 4K 2:1 and they look good. I haven't installed Final Cut or Pro Res yet....

System is Mac Pro 8-core 2.8GHz, 12GB RAM, 8800GT video, OSX 10.5.2, QT 7.4.1 w/all OS updates (but no app updates) installed including Leopard graphics update.

Still a work in progress. I am so reluctant to spend any money yet until some of these issues are resolved and we see what tools will best serve our purpose. In the meantime, I will use my Macbook Pro and experiment. My G5 Quad sits, anxiously wanting to take part in the festivities but I have to keep reminding him that he isn't good enough, he can't play with the big kids. Oh well, keep the tests coming. We'll eventually get all of this sorted out.

No.

Ever since Quicktime 7.3 on xp 64 it crashes about one in two times I open a quicktime. Exporting to AVI inside QT Pro crashes every time. I can't transcode more than about 3 seconds from one quicktime to another in QT Pro. 7.4.1 did nothing to fix it. If anything now even more things are broken. Combustion can't export quicktime now...

I pray that one of these days Divx will just come pre-installed on all systems and I won't ever have another request for quicktime drafts. :rip_1:
