Kind of Bounce problem PT11 HD Native

[c-arts]

Hi there,

i have PT 11 on a Thunderbolt HD Native card.

I often have many files to bounce from one session. (100+)

When I begin to bounce to disk with the offline function everything goes fine; the speed is with some plugins at 40x.

But after about 20 files PT starts to struggle:
I press "OK" for bouncing and then the colourful ball icon comes and the system sleeps for a moment.
It's not crashing. Then after a while it starts bouncing - at 40x again.
After the bounce process the same: the colourful ball appears until I can do the next step.

Only a restart of PT helps - then after about 20 files the same begins.


Does anyone else encounter with this problem?

I'm working on an IMac 4 GHz Intel Core i7 with 32 GB 1600 MHz DDR3

Thanks
Michael

Grasping at straws here...do you have SLEEP enabled? Disabling that is one of the required system tweaks Does it do a real-time bounce okay? Does the iMac have a Fusion drive?

I've had success using Cocktail "Purge inactive memory...." to speed things up without a Pro Tools restart.
For me it's when rendering many elastic audio tracks.

Hi there, thanks for you answers:

@albee1952: Sleep Mode is disabled! Yes, the iMac has a fusion drive!

@Darryl: I'll try that the next time!

@Detroit I'll try that too, thanks for the tip!

You should have never purchased a Mac with a fusion drive for use with Pro Tools, or you should have reconfigured the fusion drive into two separate drives (but be careful of not getting a fusion drive that uses a 4,800 rpm drive). This has been discussed a lot on DUC, and instructions on how to do that are easily findable online.

100% correct.

Fusion drive is not for Pro Tools.

Period.

I've seen this ever since offline bounce was introduced which made me give up on it.
In complex film sessions I usually have to wait for 5-10 minutes for the beachball to settle and before PT actually starts to bounce. A reel then takes about another 8-10 minutes depending on complexity and then another 5 minutes of beachball after the bounce.

In total that's actually way longer than a traditional realtime bounce.

Might be faster with small sessions but I never use offline bounce mainly because of this. (The QC aspect not even considered).

Granted i am on PC, but off-line bounce works great here. In months, i have only had a single session that refused to BTD off-line, but it would offer me a button to run a real-time bounce, which worked every time. Did the OP ever answer regarding real-time bounce working?
