I'm more an audio guy than video guy so I tend to know a little more about audio.....

With audio, whenever you make an edit (or cut, whatever you want to call it) it's important that snap to zero crossings so that you don't get clicks and pops. For instance, let's say I have 30 seconds of audio and want to cut 10 seconds out of the middle:

9:99 - 10:00 ----------------20:00 - 20:01

Unless my begin and end points are snapped to zero crossings, I am going to get a great big "POP" when 9:99 and 20:01 join together.

That said, is there any way in Adobe Premiere 1.5 to adhere to zero crossings in the audio portion of the video clip? As it stands, I'm getting clicks and pops in my audio right at the edit points of my video. Thanks.

I'm not quite sure what SW you are referring to here - the current version of Premiere is Premiere Pro, and that's actually version 7. Audition, on the other hand is at version 1.5...

Not necessarily - certainly not as far as Audition is concerned, anyway. If you look in Options>Settings>Data you will find two checkboxes that relate to this. The first says 'Smooth delete and cut boundaries' and sets the default at 2mS, and the second says 'Smooth all edit boundaries by crossfading' and normally defaults to 15mS. For normal edits, the default values are fine, and will eliminate all pops at transitions.

This software has been around a while. One of the reasons that it's so popular as an editor is that all of these little details have been attended to, and are also fine-tunable if you want. Can you imagine how much slower every edit you ever made would be if this hadn't been very thoughoughly and comprehensively taken care of? It works fine - try it!

I'm looking for Adobe Premiere 1.5's equivalent - anyone know of such a setting?

Sorry - I keep forgetting that they did a version increase - the original doesn't actually say Premiere Pro 1. And there was a Premiere 1 - hence the confusion. They quite deliberately added the 'Pro' tag at the last but one release.

Certainly in the original Pro version there is no facility for altering the default overlap values, whatever they were, and I'm not aware that they changed anything about this in the current release. If you actually have a problem with an edit, then you have to do a manual crossfade - the easy way being to do what is known as a 'chequerboard' edit, staggering the audio across two tracks. I think that there must be an unalterable default for this though - I don't tend to get pops with Premiere soundtracks anyway. The chequerboard technique originated with VT editing, where you got all sorts of clicks and pops on some machines, and the only way around this was to overlap the soundtracks at edits.
