DISCUSS: Playback performance improvements with audio clip effects
Coming to Premiere Pro (Beta) is significantly improved performance when playing back sequences containing a high number of audio clip effects. Previously, Premiere would pre-calculate audio effect information for the entire sequence duration, which depending on the complexity of the sequence, could take several seconds between pressing Play and having the playhead start moving. Now, Premiere calculates only the minimum required for playback to begin and remain consistent.
In one of our test projects, a 1.7TB sequence with 1000's of clips and audio clip effects, these changes brought our average latency starting playback from 13.2 seconds to 81 milliseconds - a 164x improvement! Your mileage will vary, of course, but expect to see dramatic improvements and practically imperceptible delays when previewing and playing sequences like this.
