Kyle, just wondering… Is the lag issue all you are experiencing with your system?

I am running a 2010 Mac pro 12 Core with Lion 10.7.4, CS6 and the Decklink HD Extreme 3D Card. Playback on my external FSI monitor has been a problem since day one. On Playback, the video becomes squeezed and green glitchy video shows to the left and right of the video. This is all after I did a complete clean install of the OS (went from Snow lep to Lion) and installed all of the drivers associated with the BM card and Quadro 4000 card.

What’s really bizarre is that this issue is only displayed in SD sequences at the moment. 1080 sequences appear to playback fine while 720 sequences do not output at all. I have only run into one other poster on the PP forum that had the same issue as myself. At any point, did you experience anything like what I described above?

Thanks in advance for taking the time out to respond?
Chris

720p Works great. SD seems fine, I’m only having the Lag issue with all outputs. Im running to a Flanders LM-2140W (HDSDI) and a Cheapo 32inch Vizio (HDMI). Ive had many good experiences with with mine. Im running the ATI Radeon HD 5770 1024 MB, but soon to get two Quadro 4000’s.

I’m also running a pretty “dirty” install. I need to reformat soon. its been almost 11 months since my last clean wipe. Card defective maybe?

Kyle, I ran into the same thing with an almost identical mac pro to yours with a Decklink Studio. Tried to find an offset option in Premiere similar to FCP7 and the closest thing I could find didn’t seem to work. Do you have FCPX 10.0.4? When I played back on X it was perfect, so I think the issue is how the BM card interprets what CS6 outputs. I’d cross reference with AJA but, well, there aren’t any AJA drivers yet.

That said, our After Effects seems pretty great, it was just premiere that was causing issues.

I’m having the same issue as well. I have a Mab Pro 5,1 with the ATI 5770, Deck Link Extreme 3D with Quadro 4000. I’m outputting to my FSI LM-2461W. It is lagging. I was looking for some sort of offset, but could not find one.

I have a new Mac Pro with Decklink Extreme HD card and when playout to tape there is no consistency. In other words, when I set the in point to tape on 00:00:30:00, CS6 will playout to 00:00:29:08, or sometimes any other frame close to that, but never the right in point to tape. I have tested the same machine and card with FCP7 and it works perfect!
I have the latest 9.5.1 driver installed but that does not seem to help, and Blackmagic does not reply to my mails…. this is immensely frustrating for me!!!

Same issue on iMac i7 with Premiere CS6 and intensity extreme (thunderbolt). FCP X syncs just fine – but not Premiere; it lags at least 5 or more frames… Did anyone find a way to offset Premiere? Can’t work with it otherwise.

Hi Guys,

I wanted to get some clarification from you about the reported lagging.

Are you meaning there is a lag between the desktop monitor and the SDI/HDMI monitor of 2+ frames? I did some pip tests today and the output was in sync audio/video wise. I was monitoring the HDMI out of the DeckLink card. Are you guys monitoring the audio from the DeckLink output or using the Mac audio output?

Could you also let me know what codec, frame rate and frame size the clips are so we can run some more tests here.

One issue we have seen is the the audio meters lag behind the playback by several frames – we have a fix for that and also a fix for the SD 4:3 and NTSC issues reported.

Our goal is to do an update early next week but i would also like to get clarification on this lagging issue as well.

Thanks,

Hi Matt, thanks for replying.

You’re right, in my instance I’m using the built-in audio for output, and BM for monitor… could this be the problem?

To clarify, if I have the program monitor on the GUI side, and output to the HD as well, side by side the HD monitor is a couple of frames behind.

Even with program monitor closed the problem is the same.

Furthermore, sometimes it gets worse and the lag builds up, other times it’s a bit less…
