ProMix Tools

ProMix Tools is a collection of four tools: MixAudio, AddAudio, InsertAudio, and JoinClips. This suite of tools allows you to import and export Flyer clips in a wide variety of audio formats, perform infinite audio mixdowns, add audio to video clips, and edit audio using a waveform interface.

Imagine setting up a project using audio clips and appropriate fades, levels, timing and length. Then, with a click of the mouse, ProMix automatically will mix all of your audio and settings to a new single audio clip! Programs include:

MixAudio - mixes any number of Audio croutons down to a single audio clip. You must have an audio-only project, or shift select audio clips from within a project to mix.
AddAudio - adds or replaces the audio portion of a video clip, still, or animation.
InsertAudio - performs an insert audio edit on a video clip. This overwrites a portion of the audio on the clip without touching the audio before or after it.
JoinClips - joins a sequence of audio or video clips together, writing a new clip that preserves both the IN and OUT points in the project. This will handle cuts only and does not handle effects.
