Alright back to 10.4.x.

Frank, thank you for trying and telling us.
Have any of you users of BM hardware noticed ANYthing being better with the post 10.4.x drivers? I'm curious about what I might be missing.

It's not a case of Blackmagic drivers being better or worse, it's a case of which work best with the AVE, which is what's actually at fault. Other video playback software works fine with Blackmagic regardless of the driver version. The other fly in the ointment is Apple's own USB3 drivers which are causing serious issues with some hardware. Don't be so keen to blame Blackmagic.

I'll run the 10.7.1 driver for a few days to see if the "unable to stop video" errors become less. I doubt it to be honest since it even happens on the systems running the latest PT12 version.

The massive increased offset of 270ms instead of 80ms on my system/screen combo is a pain. I compensate the offset in my speaker controller not inside PT because it's more accurate. But with 270ms of delay the waveform that scrolls by on screen is not in sync anymore with what you hear which is irritating when editing dialogue. Picture sync is bang-on with both drivers but I'm going back to 10.4.3 because I need to do the offset in my speaker processor to work around the annoying black-wink bug that AVID won't fix for some reason.

If the latter doesn't bother you it makes no difference otherwise. The 6-frame offset that the newer driver cause can be easily compensated in PT. I guess my setup is a bit different in that regard.

The huge delay is definitely a BM thing. Has nothing to do with the OS or PT version you're running.

I have to say that the Desktop utility is quite confusing. When you go to the "about" menu it says v10.5.4 regardless the driver installed. But when you select the "about" tab inside the settings it will show the correct driver version but then the "last updated" window says December 2015 even though the 10.7.1 is only a few days old.

Try running VideoSlave or Premiere with the new drivers. I'm willing to bet that the huge delay will ONLY be when playing from Pro Tools.

I won't bet because I neither work on Premiere nor VS.

All I can say is:

10.4.3 driver: 80ms total offset incl. projector with DNxHD36 24.00fps QT
10.5.x and newer: 270ms offset (give and take a bit depending on exact version).

all on the identical machine with the same OS.

It's hard to blame PT/AVE looking at these facts but I'm no programmer.

Either drivers can be fully compensated to run at plus/minus 1ms accuracy when genlocked with a Sync HD so sync is a non issue (try that with VS, by the way).

It's just that in my particular setup where I want to compensate with a delay in the b-chain to avoid the annoying black-wink-bug that AVID won't fix the 250ms offset can become a bit too long when you want to see the waveform reflect what you hear.

The whole "unable to stop" errors are a whole other issue I think which is definitely an AVE issue.

I was having a particularly bad day with AVE errors. Decided to try BM 10.7.1 (with a Deckink Extreme 3D).

The huge additional delay Frank mentioned is there - on 10.4.3 it was not.

So far it is running OK - but I also change another setting. I turned off "Enable GPU" under the main prefs. I was desperate looking for solutions so I can't say which change had an effect. But so far so good.

Anyone else disabled the GPU processing for better or worse? I literally have given no thought to my GPU. It's an ATI HD5870 1GB, it came with the computer, and it works.

That's a reasonably old GPU to be fair.

I know this is on Windows, but when I pimped my GPU from an AMD 6450 to a Nvidia Gtx660Ti Cuda 2GB, everything got slicker. It seemed that the GPU was actually helping the overall Pro Tools performance.

Yes it is old. I perhaps foolishly assumed fancy video cards were for editors and gfx artists. I figured mine works and has plenty of RAM... but maybe this is yet another thing PT is picky about? The compatibility doc just mentions "Dedicated graphics card recommended". Not very helpful.

It used to be Nvidia Gtx650 iirc
