HI all,
This is the 3rd computer I have set up with premiere that has some audio problems. I have 2 other friends who also agree: "2.0 has issues"

As long as you are doing simple editing where you don't have to apply alot of effects everything seems hunky dory (good). Otherwise, heavy tasking causes audio to not play back perfectly (audio pops, drops in clip volume leves, loss of audio affects previous applied)

My newest system, with 2Gig of Ram, a 512mb DDR3 video card and Pent. D 3.4ghz cpu SHOULD be stout enough, but alas, I still have problems with heavily edited projects.

I'm editing a television drama show. There are lots of clips that had background hiss that had to be filtered out and clips with low audio that had to be raised.

When I play the entire movie from the timeline, almost every other edit point (cut to a different clip) results in a loss of the applied audio effect/filter or a drop/loss in the audio volume for about first 3 seconds of the clip. If I stop the playback, back it up and re-play the individual clips, they play fine. Resume playing entire movie, and again, the short drops in audio volume or audio effects.

I did not have these problems in Premiere 1.5. Will we EVER see any updates to Premiere 2.0?

On a final note, I installed a DEMO/Trial version of Canopus Edius, Imported the same clips and applied similar effects and they all played beautifully. What's up with premiere?

Choosing "compatible" or "enable GPU effects" in the playback settings in premiere makes no change.

Any thoughts from the seasoned Premiere editors on here would be GREATLY appreciated.

Are you editing in HD? The computer I use is similar in specs to yours and I experienced the same issue where Premiere couldn't "keep up" with the audio during preview so it simply drops it. This only happens in my HD project and the results improved significantly when I set the preview quality to "Draft." My advice is to edit the sound first before adding any video effects like CC because this will cause the program to slow down significantly. If you're editing in SD then this shouldn't happen. I don't think that it's a problem with PP2.0 itself; HD editing is still to tough for most programs to handle without an intermiediate codec like Cineform.
 
All of my PPro machines are fairly similar in terms of hardware. I haven't seen a similar problem as to what you are describing in either 1.5.x or 2.0

The common item in all my installations, at least as far as audio hardware goes is that everyone has a SB Audigy card installed. Can't understand why that would make any difference, but thought I would point it out regardless.

ripupthehwy, if you are using many audio tracks with the same effects applyed to each one them you will at some point get some playback problems. Send those tracks to a Bus and apply the effects to the Bus instead of apllying the same effect to all tracks.

For example:
Lets say that you have 10 tracks with DeNoiser with the same settings on each track. PPro has to process all ten tracks witch can be processor intesive. By sending those ten tracks to a Bus you have to aplly the DeNoiser only once instead of ten times and thats much less processor intesive. Working with Audio Busses in PPro is an effective way to get good real time audio playback in PPro. The same principle goes with all audio effects in PPro.

Another tip:
If you are using an effect that you know you never will change, doing a Render and Replace on that track will make a big difference if the track has many processor intesive effects on it. By doing this you will render out a brand new .wav with all effects included in it and PPro only has to play back that audio file instead of playing it back and applying all of its effects. Again, that much less processor intensive. Working with Audio Busses and doing Render and Replace here and there is a key to good real time playback if you are using many audio track with lots of effects on each track.

Btw, GPU stands for Graphic Processing Unit and has to do with graphics, not audio. :)

Thanks for all the imput guys.

No I am not editing HD. This is all SD, and still the problems. I will try sending the tracks to a bus and appying the effect there. The DeNoiser audio filter IS the main one Im using, and having problems with. (Hmmmm funny u mentioned that filter Averdahl). I don't have alot of audio tracks. most of them on the same track, but each clip is no longer that a few seconds before it cuts to another clip. Maybe its all that cutting from one clip to another so fast that Premiere can't keep up??

You could always export your audio as a PCM (.wav) file without the "DeNoiser" filter applied and then re-import is a contiguous file, replacing all the individual clips and then apply your filter to the single audio clip.
 
Or maybe use Pro Tools or Audition to edit and process your sound and then just reimport as an umcompressed WAV? why use Premiere Pro to process and edit your sound? Once its all syched, do what khmuse says and render out. You can process the file in a 3rd party app, then import in. Do it all uncompressed WAV and you're fine.
 
You can export back and forth between PPro and Audition without ever leaving either application. Its really nice to stay with a single family of applications.

Well, you mentioned in you initial post that "There are lots of clips that had background hiss that had to be filtered out... so the DeNoiser sounded like a natural effect for that task. :)

And many DeNoiser's do slow PPro down. Audio Busses or simply use the Render and Replace command in PPro on those tracks and thus replace them with a brand new .wav could probably do the trick for you.

Moving your audio and video files to seperate disks and defragging the disks may help as well.

If you have Audition, it is well worth the time to learn it. I can't stand to use Premiere to do any audio work beyond simple volume adjustments or transitions. Audition has better tools for noise reduction as well. As khmuse has already said, the two applications integrate nicely in 2.0.

Thanks for all your help guys. I have been SOOO frustrated with this thing! Yes it seems that the DENOISER filter is the culprit. I took the filter off the clips and they play much smoother. I then did the sub mix thing and applied the filter there. It's not perfect but A GREAT DEAL BETTER !!

Thanks again.

Question as well...

Question as well...

Speaking of moving back and forth between PP and audition, I recently tried just that ... The audio came out really sweet (even for a novice like myself... learning audition and all...), but when I replaced the file on the PP timeline... it was no longer in sync.

Can anyone suggest why this happens, and possibly a "quick" tutorial on how to prevent or correct it when it does happen...???

Thanks in advance guys...!!!

Yes, if you tell me what version o f Premiere Pro you are using and how you did it, ie how did you bring the audio from PPro to Audition and how did you bring it back from Audition to Ppro again. :)

PPro 2.0 audio problems

PPro 2.0 audio problems

I have had similar problems with 2 programs I have recently worked on. I agree with thre comments that have been posted here. I have used the same audio filter with the same playback problems. I thought my 45 minute shows were never going to work. I also had "low on memory" warnings as well. When I mastered out to tape, there is a check box for "render audio before mastering."
This worked perfectly, yet took quite a bit of time, prior to the deck kicking into record. What I don't understand id why Adobe has this extra step. It should be incorporated with the standard render in the time line when you hit "enter." It is very awkward to edit around this with a timeline that plays back so poorly. Its like the old days of NLE's when you couldn't on-line the full res video.

Exporting was hard too I had to disable are my start up items, and reboot and exported immediately so the "low on memory" warning didn't haunt me again.

Hope this helps.
 
If my audio isn't lining up with my video while editing I do the following:

Stop the timeline (space-bar)

Look at my hard drive light on my system, its always blinking like crazy and something is happening

After about 10 seconds it goes away

I resume playback and everything is fine.


What's happening is Windows XP will on a whim decide to drop whatever is in the physical ram to the Swap File. And generally the swap file gets spanned across multiple drives for performance (espically on high end workstations). When this is happening, PremierePro can't keep the datastream necesasary to play-back the video, so it cuts out the audio (P.pro detaches the audio stream and makes a copy so that audio effects can be rendered in real time)

Basically, this is just a fault with the program. I think that video playback should have higher system priority than page file dumps. But alas, thats just how windows XP is.

Just feel glad that your system cost half of what a G5 did. :D
