Over the past couple of months I've been putting together a portfolio of sound design projects (http://flavors.me/mritterp) to try and get some work on short student films and such, but I'm concerned about my mixing levels for the portfolio pieces. I have calibrated (and mixed) to 78 spl giving me 20 db of headroom, and figure that's probably the best way to mix when I'm applying for internships where the listener will be in a studio. But I'm afraid that the student filmmakers who I'm trying to work with can barely hear my work (compared to levels they are used to online) and dismiss me as a candidate. The other problem is that it doesn't leave me with much consistency in the overall audio levels on my portfolio through different types of projects.
Should i not bother mixing portfolio pieces to 78 spl? Also general advice on how i could make my portfolio better would be welcome.
