Yes. It was ambient music in the background being played by a DJ .
Impossible to avoid it getting into the track
Lean to do audio ducking and leave the original track there and add your own music to it. It's the same thing whether you use your music or someone else's.
Well, BTS has constantly brought it to our attention, that he believes the iPhone is the ideal tool for event coverage, both in audio and video aspects.
Unfortunately, that really isn't the case. Not only has the current iPhone done away with the standard headphone jack, but it never had either one of these:
The 1st, and most important being the standard microphone XLR connector, (left), the other being a 1/4" plug, which is commonly used as an adapter to mate XLR with the more prevalent 1/4" "phone plug".
Even the least expensive standard microphones are available with pickup patterns approaching uni-directional.
@Bigtruckseries I feel your pain with aggravations such as the one you've encountered with the copyright violations.
However, you have to take into account, any paid entry event can simply be tagged as "copyrighted in its entirety", by those promoting/hosting the event. Obviously this is more prevalent with stage and theater productions, but it can extend to something as seemingly public as a car show. IMO, they tagged you with the music violation, because it was the easiest and most convenient "loophole" to exploit.
I'm suggesting you either take more sophisticated equipment to cover these events, and/or try and coerce some rinky-dink local (Read "community") newspaper to provide you with a press pass, in return for a little blurb and a few stills of the event.
And yes, I realize the more sophisticated the equipment you carry into an event, the more scrutiny it will cause you to be subjected.
Still, the reality is, using a "real camera", and a decent directional mic will resolve the ambient sound issue, while still allowing you to do your voice over. What other repercussions it might cause, I have no idea.
Truth be told, you don't have to use the sound track from the camera. Another alternative might be to simply do a "voice over" at home. You just grab some stills of the placards next to the vehicles, plus any brochures you can lay your hands on , and use that information for your, (to be added later), narrative
