Quicktime + Leopard 10.5.1 + ProTools 7.4.1

[Mixmaster Nate]

Hi World,

for those who may be aware of the lag time (up to 3 seconds) between pressing play and/or stop when using a Quicktime file in a Protools session, does any have any knowledge of any software patches or fixes out there for this incredibly annoying issue with PT7.4.1/OSx10.5.1/Quicktime Pro7.4.1.

It is in the PT7.4.1 read me that this is a known issue.

I do a lot of post for commercial television here in Australia, and always digitise from the online master tape a DV-PAL quicktime movie (.mov) - then imported into Protools for my video reference. I've found that this has been the fastest way to work, until now. The issue is apparently an Apple/Quicktime problem, not a ProTools problem.

When scrubbing or trimming audio regions within Protools, the vision scrubs in sync with no lag - the lag is only present when playing or stopping the whole mix.

Opening the DVPAL movie directly with the Quicktime application and it plays immediately - no lag!

So so annoying and frustrating.

It's not a RAM issue with my system, as I have 8GB on a Dual Quad 2.8 Intel Mac. Also running a dedicated external drive for video (FW800)

Hope someone can spread some light on the issue.

Thanks.

I don't see this with Meridian Avid files and a 2.3 GHZ G5, Playback starts instantly. Is it possible it is a DV issue? try transcoding a small section to MJPEG-a and see what happens.

I assume that if you remove the movie track it all plays instantly as well?

I am running PT7.4 cs2 with 10.5.1 on an i-mac 2.8g with 4gig of ram and most of the time it starts the session with DV or HDV picture instantly. I have had it slow up and a re-boot of the control surface a 002 cures this. I also think it may occur following use of the 002 with i-tunes via core audio and the re-set seems to clear this.

Hmmmm....

Okay, I've tried all these formats so far;- DVPAL, AVI, MPEG4, DV STREAM and QT Movie.

A fix if any one is interested - all formats had the same 2 - 3 second lag, EXCEPT AVI, there is NO lag when using an AVI file (ie; .avi)

Maybe Digidesign could test this and release a note to all who may have been experiencing the same issue.

Thanks. I'm happy again.

Hi Mixmaster Nate,

I would like to ask which "QuickTime Playback Priority" do you have selected into Setup > Preferencences > Operation > Video.
I suggest to set it to normal and to have unchecked "High Quality QuickTime Image".

Second, I would suggest to give a try to Motion JPEG-A Codec. But your problem is not related with a CODEC as I believe.

All good. My 'movie playback priority' was set to normal and high quality was unchecked.

I also spoken to Digi support over the phone, it appears to be a communication issue between Quicktime and Protools, and Digidesign are aware of it.

Hopefully a fix in the next release of QT/OSx - meanwhile, I'll stick with the AVI's...

I'll attempt Motion JPEG-a as an experiment nevertheless.

Thanks.

I've just installed PT7.4.1HD and Mac OS 10.5.1 without updating Quicktime (it is 7.3) on a new Mac Pro 8 core. Instant video playback. I'm not sure if I want to update Quicktime right now - QT7.3 is working!!

I had this problem with PT7.2LE a couple of years ago. It was very slow working that way. I could not figure out what the problem was. Tried too many things to mention.

I did a fresh system and PT install on a different partition of my drive and the video slow down was fixed. I went back to the other partition and the slowdown was there - same session, same PT version, same system version.

I never did figure it out.

I just installed QT 7.4.1 on my PT 7.4 HD3 system.

Picture plays without delay.

Hi there,
I just fixed the problem on my system by exporting the quicktime file in QT-Pro without sound.
If you need the sound , import it from the original

This seems to work !
