I need to come up with an alternate item which can take the place of a clapper. I'll be filming out of a pack and in the back country for some time.
What could take the place of a traditional clapper that I alone can use, preferably something that would fit within the palm of my hand, that I can "click, snap" to sync my reference and recorder audio tracks? Any ideas?
I don't know how "rough" you'll be roughing it but I've used this when shooting on my own in the field. If you have an iPhone this works pretty well -
- plus you can make shot notes.
Battery powered, small photography flash. That flash is only one frame in duration, and should be bright enough for all cameras to see it. Then in FCPX, make a marker on each flash frame, and sync to markers. I've actually done this on some land I have that is total woods, where sound won't travel well enough to be picked up and sync (cameras a good distance apart, plus drone), and it works really well, even during the day.
You can not only record a clap, but make Markers while recording (just tapping) - which appear inside FCPX as markers!
So, your iOS device not only mutates to an audio field recorder, but a script-assistent too ....
Very handy, lil' known ...
