Avid’s new stereo tracks and Real Time Audio Suite effects are both liberating and frustrating. Introduced in Version 5, stereo tracks allow editors to handle stereo pairs as single objects in the timeline, and control them with a single set of audio keyframes. RTAS effects let you apply up to five real-time audio filters to each track, quickly and easily. That’s the good news. The bad news is that you can’t automate these effects in any way — you can’t turn them on and off, and can’t change their values, anywhere within a sequence. Nor can you edit them from one sequence to another — you have to copy to a bin first.

Stereo clips are problematic, too, because they can only reside in stereo tracks. You can’t put a clip wherever you want, you have to dedicate a track to these clips, again, throughout your show. Meaning that if you have only a few such clips, you’re wasting a whole track for them. And since Media Composer only plays 16 tracks, a couple of stereo tracks — each equivalent to two mono tracks — can waste resources big time.

But despite these limitations, I’ve been using both features to good effect, mostly for editing music. The technique I’ve come up with is to dedicate two stereo tracks to temp music, and one to reverb. That’s right — a whole track to reverb — the same reverb throughout the show. For picture editors used to conserving track space, this seems almost absurd, but once you’ve wrapped your mind around it, it can be effective. End your music wherever you want, then cut the last beat to the reverb track. Voila — you’ve created a ring out. (In some cases, you’ll need to add short dissolves or fades to smooth out the transition.) Avid’s new AIR reverb plug-in, included with MC 5.5, is particularly good for this purpose. Unlike the old D-Verb, AIR reverb is more easily controlled and sounds better. You can simply set a duration (Reverb Time), measured in seconds. You’ll also want to adjust the Mix parameter, which controls how much of the original, dry audio is combined with the reverb (50% is a good starting point).

Avid could make some improvements to this situation. Automation for RTAS is essential. Likewise, the ability to edit RTAS effects when cutting from one sequence to another. And the AIR plug-ins, good as they are, include presets in Pro Tools, which are missing in MC. Finally, if we’re going to segregate stereo and mono clips into specialized tracks, then we need more tracks — 24, at least.
