Audio Sync issue with CS3, but not CS2

[Blast1]

You have to clarify a few things, Where is the delay? when you are playing internally using Ppro monitors, or externally going through the intensity, if externally, where are you monitoring the sound? on the external device or using computer sound while playing back the video externally through the Intensity, also is it component or HDMI?

I have done a complete test between CS2 and CS3 using a clapper and capturing at different presets. There is actually about a second or two delay with CS3.

The delay would be in the audio not be in sync with the video. The delay happens playing either on the internal ppro monitor or on the intensity. The delay is about the same. I tested audio output on both cards, the Sound Blaster and Intensity. Both cards had the delay. I also tested the audio on a HDMI monitor using the Intesity card (audio send thru HDMI cable). The analog audio was being sent directly to the speakers (thru a mixer).

Everything worked perfectly using CS2. This includes audio being sent HDMI or thru the analog mixer.

Video is being sent to a HDMI and Component monitor on the Intensity card. Presets were also used that do not use the Intesity card. Both NTSC and HDV presets were tested.

Last time I checked the Intensity site there was no remarks saying it supported CS3 only Ppro 2.

The Intensity Pro does now support CS3. Al though, the install process can be a pain because the presets had to be copied to the proper directories manually. The only issue I have with the Intensity Pro is that the sources for multicam editing are blank. It is a bug that has not been resolved.

I don’t believe this has anything do with the Intensity Pro card because I still have the same audio delay (out of sync by a few seconds) when using presets that came with Premiere (non-Blackmagic presets).

Capturing HDV through firewire using Premiere Pro CS3 is pretty much broken.

I tried capturing over 20 tapes and not a single clip was usable due to audio synch problems and/or multi-cam synch problems. Some of the clips would look fine as far as audio synch, but those same clips wouldn’t synch properly with other clips with multi-cam.

Furthermore, projects would take forever to load (more so than usual) and CS3 stability was bad (more so than usual) if I had a CS3-captured HDV clip in any project.

Clips from the same tapes captured in PPro 2.0 or Vegas worked just fine in CS3. Other people reported that HDVSplit worked fine as well.

Use another program to capture the clips. If you capture your HDV with CS3, you are asking for problems…

[Richard Eary]

I believe there is more to the picture. Yes, capturing HDV through firewire using CS3 caused synch issues, but I still had sync issues capturing analog through Intensity Pro.

I am currently recapturing my tapes in CS2. That version of Premiere seems to work much better than CS3.

[Jeron Coolman]

I hadn’t realized you were capturing analog through the Intensity. I thought you were just monitoring through it.

I’ve captured the same tapes analog through a Xena LH and HD-SDI going through an HD-Connect LE, but with Aja’s Machina capture program, not Premiere Pro’s.

That uncompressed HD footage all worked fine in CS3. I had to turn to another NLE for my HDV workflows, because I encountered too many bugs in CS3. Premiere Pro 2.0 didn’t have any of these problems, it worked pretty good.

[Richard Eary]

Adobe Support said that the Blackmagic drivers may be causing the problem even if I am not using a Blackmagic preset. I am going to un-install the drivers and see if the problem still exist. Al though, Blackmagic has not heard of any issues.

How much drive space is enough when working with uncompressed footage? I estimated I would need 10 terabytes. 500 gigs per tape.

[Jeron Coolman]

That’s about right, give or take depending on whether you go 8bit or 10bit. 450gig for 8bit per hour and just under 600gig for 10bit per hour.

Aja has a great data rate calculator and system test utility for free download on their web site.

[Richard Eary]

It sounds like HD is pushing the limits of technology. Not long ago a terabyte wasn’t a common word.

Is it possible that the videos are not being captured correctly? For example, video with out of sync audio plays exactly the same in Liquid. So this isn’t an issue where it plays incorrectly. Looks more like an issue where it captures incorrectly.
