Okay, so there is a first time for everything and this is mine. I've developed a commercial, and am sending it to the stations today to place. They require the following: - 5 seconds of slate (150 frames) - Audio type on the slate (stereo or surround) - 2 Seconds of black. I'm fine with the slate and the audio - but do you think the black comes at the end of the commercial, or before it begins - directly after the slate? Thanks all!
