CS4 is a huge and heavy program. Things may have changed slightly, but I believe that Premiere CS4 mainly relies on the processor. We use Intel q6600 processors at work, and CS4 often seems sluggish. particularly Encore. Encore program windows get that strained "transparent" look as they take several seconds to open. Premiere sometimes goes "white" as if the program crashed, then snaps back after a few seconds.
I would take a look at cost/performance advantages of an expensive graphics card. They can get very expensive and I believe they provide little to no benefit for Premiere users. They are designed to improve performance for 3d programs like Maya.
Tom's has a recent article on one of the new high end cards:
Thanks for that, Charles. I've also experienced the things you mention and agree that it does seem that CS is quite a hungry beast in its latest form. I'm looking at increasing my memory tomorrow (I currently have 2Gb and can upgrade tomorrow to 8!), however that 8 is coming from the old machine that was affected even worse by the "problem", so I'm not expecting such an easy fix. I have also decided that I will go with the expensive graphics card. I do agre with you that it may not make a huge difference, but it's already paid for and besides, if a job's worth doing ....
I haven't noticed any delays of this type with my own multicamera work.
I had a similar problem once and it was related to audio settings. Changing them fixed it. Might not be the same in your case, but I'd check the audio hardware preferences and make sure something hasn't been set incorrectly. I believe that "built in line output" with a buffer size of 512 is the default.
I am getting the exact same thing - only my playback delay is closer to 3 seconds.
I'm editing a lecture which is about 1:21:00 long. When I play the Sync Timeline (the source of the mutli cam sequence) the play response is immediate. When I'm in Multicam Mode I have to wait at least 3 seconds before playback begins. And my machine is pretty beefy.
Then I discovered what the problem was!
I was working with an M2T file and an MXF file. The audio from my lecture was embedded on the M2T file. If I rendered the audio as a Windows Waveform (DV settings: 48K, 16 bit stereo), the response goes from 3 seconds down to not even half a second - something that "feels" like I can do work again.
So if you're experiencing playback delay - try re-encoding your audio into something that the computer will have an easier time with.
Welcome to the forum and thanks for posting that.
Question: were you able to use Render/Replace on your encoded Audio to convert it to a PCM/WAV and then replace the encoded Audio on the Timeline? Note: this only does the Replace on the instance in the Timeline, and not in the original source Clips in the Project Panel.
PS Edit in Audition (or Soundbooth) basically does the same thing. Render/Replace does it without openeing either of those programs.
