Yes, that will work.
Maybe you can use just one tentacle, only on the camera. But please check what happens with the timecode if you turn off the Zoom, or replace batteries. I heard some contradictory reports about that.
As there is no timecode input available you have to use an audio input on the A7 to put timecode on. After the shoot, with Tentacle Sync studio you can read that audiotrack and make new quicktime files with new TOD timecode. Then sync it, or sync it within this app.
So, my a7sii didn’t jam the timecode. instead, I use tentacle sync to jam the TC and recorded into audio track, and send it along with the video into Atomos Ninja Flame and save into file(for instance Apple ProRess).
And mean while, another tentacle sync couple with my Zoom F4 record the audio with TC coming from the Tentacle Sync.
later on, when I get back to my office, I can do the syncing process through Tentacke tool or other application. Is that right?
thanks for any suggestion.
