I have a Pro Res file for a Movie Trailer
This file has 8 different channels
The music goes up & down (because of dialogue & sound effects)
Most of the channels are fairly clean & it sounds like in each channel where theres music & sound effects you hear sound effects in different spots
But I think using all of the channels with good editing / some sound looping & mastering a sound effects & dialogue free version can be made from this
Anyone interested ?
