I am just wrapping up a television ad, it's my first one, and I want to make sure that my audio levels are set properly. I understand these may vary depending on broadcaster, but I'd love to have a good base. The commercial (which can be seen here for reference using the password "sja": http://vimeo.com/7636971) is just a music track and then we go to some street ambience at the end. I have my levels peeking at -12.
So far I'm doing everything by ear, are there standards I should abide by? Should I lay bars and tone? If so, just what the heck do I even do with bars and tone? I appreciate the help and, as this is my first ad that I am delivering to a client that is also fairly green in commercials, if anyone has suggestions as to how to present the final product (i.e. slate for 5 secs, bars and tone for however many seconds) that'd be a good bonus.
I make music videos for broadcast and have made several hundred which we have broadcast in the past. These are mpg2 files where the audio is set to peak at -3db on the standard FC timeline.
The new broadcaster we are moving to has a technical spec of -18dbfs and we sent over two files to test - one he rejected because it was -100dbfs(some classical music) and the other was -80dbfs both had the peak audio set to -3db
Now we are setting up a classical music channel and dynamic range cannot be messed with - so what do we do?
