recently purchased a 17' MacBook Pro and Jitter - in hopes to gain some increased performance & to use shaders for video. I've been a long time Max/softVNS user, and my performance apps run SUPER smooth with an older G5/10.3.9/Max 4.5 set up.
When I started using Jitter I encountered a serious playback 'hiccup' or 'stutter', when playing even 1- 640x480 photojpeg (med quality) movie.
- I tested GPU & CPU based example patches.
- I made super simple patches as well.
(1 jit.qt.movie & jit.window or jit.qt.movie & videplane)
- I've tried RAM loading & RAM Disks.
- tried metro, qmetro, qlim
- tried tweaking Performance settings for Max
- tried standalone apps
NO MOVIES will play smoothly, PERIOD.
Even when mixing 5 video streams on GPU, the stutter happens at similar intervals, in each movie.
I've tried every optimization, read every tutorial, downloaded every sample I could find, read every thread on playback issues -
( just mentioned this to avoid replies like "did you read the manual" o r" id you try the eample patches". I have. I've spent hours and hours researching)
-- OR, of course - is it this machine?
(Mac 17" 2.4 10.4.10/ 2gb ram / 256 - GeForce 8600M GT, had last version of QT - and recently tried 7.3.0)
- I optimized the OS - cut every CPU task I could (SpotLight, Dashboard Network, OS window shadows, etc etc -)
still the same jump in playback every 3 - 4 seconds a stutter.
I then tried the example patches on 3 diferent G5s (dual 2.0 & quad core & intel G5) -all with same results!!!
Dont mean to be a wise ass here, but - Is this where the name Jitter comes from?
The stutter is very visible, in my opinion unacceptable for producing DVDs or exhibition - and I just cant believe other artists would just live with this!?
---- Support ----
so then I turned to Cycling74 - and their response was to give a detailed account /specs etc. - I did & took 2 hours explaining/writing, etc.
the got a simple, deadend, frustrating, response from Andrew B:
"Smooth playback is one of the things that we will be
exploring as we develop future versions of Jitter."
Does this mean when it was released ( for $$$) it wasnt even playing 1 movie "smoothly"?! - it wasnt explored prior to selling the software?
I've read many threads on low-priority queue - threading etc -
and even read about the video card being "underclocked" by apple for design / heat reasons. - that it runs better, faster on PC's
I was wondering if anyone has tested or regularly runs Max/Jitter in Windows Vista on a MBPro - and if the video playback is better? (different drivers, and more control over video card)
As I've just invested over 4000$ buying this machine FOR live video + 2 weeks developing, I jast cant afford to spend $ and time buying Vista & installing etc, just to realize theres no improvement - the stutter is still there...
thanks in advance for any help in this matter - I have hit a brick wall and am running out of time for product on a project!
