Audio sync

Should audio sync be an issue?

Well I would hope not.

The way I do it is that I record video with my nice Canon 1DXIII which has audio, and audio with an audio recorder on my shirt, and tell final cut pro to make a synchronised clip. Simples.

The camera audio is not good, it ends up with mechanical noise from lens focus, and echo, but the audio record on a shirt mic works well.

I have since changed from using a Tascam and radio mics to my own audio recorders for my shirt.

But someone asked how to sync audio with my new recorders?

I was "well, sync to the (crap) audio on the camera", which fooled them as they were talking of sync of raw video only and raws audio only.

So I made a feature. My audio recorders will now make a clear 1s tone at start of audio and exactly aligned a clear red LED on the front.

This makes aligning video and audio easy.

But I never expected to use it. Well, until I did.

I recorded a video, direct on final cut pro, on my mac studio with monitors, and weirdly they have bad audio sync!

P.S. someone said would be nice of LEDs off during record, and now that is the case for dark mode.
