9.5.3 Driver Eats My RAM – PPro CS6

[Andreas Wojtaschek]

I can confirm this.

Since 9.5.3 I have massive problems with CS6.
Especially with AVC Intra footage.

Hey guys,

This sounds odd, not sure why the codec type would cause this sort of thing since Premiere Pro itself handles all the decode, but it certainly seems like you guys are experiencing it.

Can you give me your system details here and more specifics on the format you’re using and how you’ve configured your preset (rather which you are using?).

Thanks

Hey Joshua,

Thanks for looking into this. Here’s my system specs:

CPU – Intel I7 3.2ghz
RAM – 16gb
Windows 7 64 bit
Nvidia GeForce GTX 285
Decklink Studio

I’ve seem this RAM issue happen with all sorts of sequence presets, but I first noticed it when playing out a 10 minute long “D1/DV NTSC (0.9091) 30fps drop frame” sequence (yes, we still work in SD at my TV station, AND still roll out to beta…I know, it’s a sad sad thing).

Let me know if you need any other info.

Alan

Cool Alan,

Thanks for that information. I’ll have someone test this now. Are you using native DV footage? I’ll get this setup in our lab today to look at.

Hi,

Same issue here, i tried with 9.5.3 and with 9.6, both eating RAM, i had to downgrade to 9.5.2.

Another issue i’m experimenting is that there is a delay from the desktop viewer to the video output of 5-6 frames, which is a pain in the ass to audio sync editing. This delay is there in every version. No delay with FCPX or FCP7.

I’m using a MacPro 4,1 – 16GB RAM – RAID 0 6TB and Decklink SDI.

[Joshua Helling]

Where is your audio coming from? Are you connected to the Decklink or are you using the desktop speakers?

If you are go to Premeire -> Preferences -> Audio Hardware. Make sure that setting is set for Blackmagic Audio.

This will make sure that the audio and video are both coming from the Decklink board. This will guarantee they are in sync at the board (there might be a few frames delay from the program monitor, but this is normal).

If you use different devices to play audio and video we cannot guarantee A/V sync.

This of course means that you have to have a monitor that can either monitor audio from SDI or you will have to get a de-embedder to monitor the audio via Analog or AES.

Hi Joshua,

The audio is coming out the Blackmagic and it is indeed in sync with the video on the external monitor, the problem is it’s delayed 5-6 frames from the premiere viewer, so you say this is a normal behavior? This won’t be corrected? Is it a Adobe problem? Because in FCPX and FCP7 this doesn’t happen.

Thanks

Hi David, Joshua,

Please allow me to hijack this thread a little further… 😉
I have a Decklink SDI card and a similar problem. About 5 frames delay between program monitor and the external monitor. When I send audio through the Decklink SDI it is indeed sync with the video on the external monitor (as David reports) but I can’t look at the program monitor on the computer screen, because it is horribly out of sync.

As I posted earlier, we need the following:

1. speed up displaying of frames from Premiere to the output card->external monitor. Driver optimization? Users with Kona3 cards report both monitors and audio in sync, and with final cut 7, there is also less lag, so it must be possible to have a lot less lag at least. In the current situation it is just too much.

2. I can understand that some latency in the path to the external monitor may be unavoidable. Also external monitors themselves have some lag. To compensate we need to be able to set a delay for the program monitor so that what it displays is sync with what can be seen on the external monitor. Final Cut 7 has such a setting.(under system settings -> play back control -> frame offset.)

3. Another delay, but for the audio only. This way, people who are using a different interface/path for the audio can adjust the audio delay to make sure their audio is perfectly sync to the picture. Also “sensitive” people like me 😉 can trim audio in sub-frame units (in miliseconds for instance) to make audio sync even more precise.

My conf.: Mac Pro (mid 2010) 8-core, 24GB RAM, Quadro 4000, Decklink SDI with 9.5.2 drivers. Pr6.0.1

Cheers,

Carl.

Actually FCP7 (at least) behaves similarly, but I believe it’s only like 3 frames or so off. This is a result of the buffering. I’m not sure why the offset is so far, i’ll check to see with product management to see if this is normal, or if it is something that can be improved.

the good news is that we have indeed reproduced the memory issue and are writing it up as a bug today and the engineers are already looking at it.
