Durafly EFXtra 975mm Racer - Video Capture Challenge 4S Flight


In 1080p 60fps - This is a Video Capture Challenge Flight of my Durafly EFXtra 975mm Racer.

Durafly EFXtra 975mm Racer - Video Capture Challenge 4S Flight (5 min 26 sec)

My friend Brad had been looking forward to the challenge of capturing my old Durafly EFXtra "Bolt" on video this past weekend. He's been taking excellent footage of my EDF jets, but the EFXtra is a completely different animal to capture well (if at all) on video. This is also his first experience seeing an EFXtra up close in action.

Will Brad manage to keep his video target locked? Stay tuned!

Suggest you edit the video sound cutting frequencies below 1300-1500 Hz to reduce wind noise

Thanks for the suggestion I thought about doing that, but then you’ll get the other skeptics that will say that it wasn’t really that windy.

then you can do it on 70 % of the video explaining what you made to reduce environment noise.

Not a bad idea. The other issue that I came across is being able to keep the sound of the “EFXtra whoosh” while reducing the wind sound.

I’m working off of iMovie in my Mac Air. I know there’s other editing software that allows to split sound waves so I can reduce things like for example an annoying talker on the field that can’t keep his mouth shut, lololol. But that software is quite pricey. iMovie is free.

Hate the wind noise. But love that whoosh.

try with the equalizer : motor noise is well above 1300-1500 Hz and wind noise is 70-80% below that frequency. I did use Sony sound forge 9 (that I got free) that allow to edit also sound of videos. And you can do it on any part of it at your choice

Thanks man. I think I figured out a way to reduce the particular wind noises when using iMovie. It definitely helps cut down the abrasiveness of the wind. Thanks for the tip!
