Audio sync issues: Premiere or Blackmagic’s fault?

Posted by Hannah Sander on October 22, 2014 at 4:04 pm

Hello!

Well, I’m at a complete and utter loss here.

The studio I work for has recently made the switch over to Premiere from FCP7. However, over the past couple months, I’ve been experiencing horrendous audio sync issues:

1. I will bring my perfectly synced clips into Premiere, get them edited in the timeline, and they’ll be perfect for a while, even during playback. Then there will be a weird dubstep-esque audio glitch and all my playback is out of sync! Not the clips themselves, just my playback. There’s no rhyme or reason. I can usually solve this by restarting Premiere. (I’ve also experienced a little of this sync issue in After Effects)
2. Within the last few weeks I’ve tried playing back in my source monitor and I’ve been experiencing, no joke, a robot voice. More often than not now, I’ll either get robot audio or no audio at all when I double click clips and play them in the source monitor. I’ve even had robot voice once or twice in my actual timeline.

I’ve tried changing my audio and video playback devices to see if it fixes anything, but I have issues no matter what I select.

My question is this: does this sound like a Premiere issue, a computer hardware issue or is it my Blackmagic Intensity Pro? Are there settings I’m missing?

Here are my computer specs:

Mac Pro
OS X 10.6.8
6-Core Intel Xeon
2 x 2.66 GHz Processor
32 GB Memory
ATI Radeon HD 5870 Graphics card
Blackmagic Intensity Pro (Desktop Video 9.5.3)
Adobe Premiere Pro CS6

As you can imagine, this makes client screenings extremely embarrassing. I’d appreciate any advice!

Hi Hannah,

Sorry for the delayed response I just stumbled across your post. I hope things are going smoother for you now and if they are please share how you corrected it.

First things that jump out are your running on very old software versions. I’d update to at least Mac 10.8.5 or higher. I’ll also update your Blackmagic driver to the latest version. They’ve made many fixes with audio sync related issues since the driver you listed.

Hope all is well,

Thanks for the reply Peter!

That’s exactly what I ended up doing. Once I updated to OS X 10.10 and updated my Blackmagic driver, all my issues have been solved and it’s working like a charm!
