Thanks, the cameras pitch automatically based on the rockets acceleration and liftoff is detected with a switch on the rail.

Great footage! Could you please post a picture of your pitching system? It sounds interesting!

Here are two videos I took off of my set up filming rockets at the Spaceport Americas Cup. This one pitches and follows the rocket and shoots at the default 1,057 fps.

I'm impressed with the performance of the CHronos cameras. They ran about 10 hours in 107F/40C temperatures and had no difficulty with them at all.

The mechanism is straightforward, a geared motor controlled by a Pololu Jrk21v3 motor controller with feedback (https://www.pololu.com/product/1392). The feedback is provided by a potentiometer to provide position. It is triggered via a switch at liftoff and uses a slight delay. The other cameras in this particular set up are the Sony a6300 for stills and a Sony X1000.

What Lens do you have on the Chronos in that Picture?
Looks fairly wide to me, like around 8mm or 6mm or so?
Maybe Kowa?
Nikon1:
Finaly sombody did a (more or less) proper Comparison between the Chronos und and an Sony RX, which has the same Sensor as those Nikon1-Kameras (and Therefore basicaly the same Image Quality).
Also in the Comparison a Phantom from Vision Research.
Chronos seems to have the smallest Dynamic Range in that Comparison.
Still Waiting for that HDR Mode on the Chronos. Chronos could have way better Dynamic range with the HDR mode Than any of those other two cameras, realy looking forward to that.

That Video is not my own work btw. It is from BTP/HPC on YT.
