An experiment with the Mavic and audio capturing

tubedroner · Feb 2, 2017

Tried out audio recording with the Mavic today. Used my phone as a sound recorder and my hands as a clapperboard so the audio was synced, eventhough it didn't matter that much in this case. Could still be useful for example when shooting loud fireworks or even a music video. Just like it is in real movie-productions, sound and picture separated

This scene had a lovely sound with the water running and birds chirping, could have gotten really nice audioscape with proper equipment! Now the wind was the enemy with the phone. Additionally, I don't know what Youtube does to audio, but the levels were lowered significantly when the clip had loaded, they were perfectly fine in Premiere.

How did you sync the sound with the video? Some more details would be good. Cheers,.

Very nice mate. I bet this place looks amazing in the spring.

Hi twinchrissy,

First, I started recording on both the Mavic and audio on my phone. Then I simply turned the drone to record me and clapped my hands together with a large movement, like they do with a clafferboard, making sure that the moment of impact could be clearly seen on the video. At the same time a made sure, that the clap would make a clear spike on the audio meter. Then I kept both rolling. In editing, I imported the audio file to my timeline, searched the "clap-spike" on the waveform and matched it to the very frame that my hands got together on the video. Ta-dah, audio in sync! At least for the needs of an amateur hobbyist.

Thanks, it is worth a second visit when the leaves start growing, indeed!

Thanks tubedroner. Ok, I'm probably being dense but I can see you got an audio file and a video file but what software did you use to combine them? Was it iMovie or Final Cut or something like that? Cheers.

this has me thinking now... maybe attached something like this instead of a phone?

maybe even dangle it with a string below to help avoid the prop noise? also some foam over the receiver for wind? I may just have to test this!

I use Adobe Premiere Elements 15 for editing, just imported the audio to my project and used it on the audio track.

I wouldn't go through too much trouble trying to attach any audio recorder to the drone. Better off using a separate device separate from the drone, there's hardly any use for the propeller noise. I could see someone doing a stand-upper while facing the drone somewhere up and talking to a mic attached to a separate device and syncing audio as described.
