I have a question relating to the mixing and mastering levels of a film's audio soundtrack and problems I have since noticed after a project have been completed.
I have been freelancing in sound editing and design for short films for a while now and I am confident that my home audio setup suitable for independent films. When I finalise a films audio soundtrack, I can see and hear that the levels are not peaking or distorting on any of the tracks. I listen to the audio on my BX-5 monitors, laptop speakers and headphones so I can feel comfortable that the important aspects of the mix is sounding the best as it can from a variety of sources.
My problem is this; two films that I have worked on have had peaking/distorting audio at the loudest points of the films when screened through DVD's on different viewing platforms.
Film 1 was played back on my home TV and distorted at the loudest point on hearing an ambulance siren, and Film 2 was shown at a premier event screening and distorted when a final 'boss fight' erupted. I've since checked back at my sessions I can't seem to understand why it's happened. I feel satisfied that I checked my levels in Pro Tools as well as different sound sources correctly before signing off on a project.
Does this sound familiar to anyone, or does this sound like mixing/mastering faux-pas? Am I mixing too loudly or too quietly? Is there something that I missing entirely when listening to my levels or exporting the final audio stems? I am struggling to work out why the levels sound fine on my home computer network (inside and outside of Pro Tools), yet the films appear to peak/distort at the loudest points when played back on DVD's.
I will admit that, with Film 2, the completion deadline caught me by surprise and so I wasn't able to test on more sources that I would have liked. But Film 1 was screened at a cinema last year and I noticed no problems what so ever, only playing it back on a home TV that I noticed said problem.
Thank you all very much for your time, I look forward to hearing any advice or tips that you may have.
