a After Many years in the industry, we realized the chain of sound in movies and television was not optomized.
So many budgets were blown before even starting the post production and record the final dialogue.
Production Sound isn't the most reliable and the smallest imperfections can ruin a perfect scene.
ADR has many times been made as a last minute afterthought and can usually be noticed as such by the viewers.
Since most productions have highly qualified sound engineers on set, one way to maximize their potential is to have them record all the additional content from dailies or any recently filmed scenes.
Even the times when a scene went great and all sound was recorded flawlessly, theres always the chance a word or two (maybe a profanity slipped) would need to be recorded.
With our Trailer, its easy to budget the sound production since you know it wont be a surprise fest of ADR in the post production.
