Nice. It would be interesting to see the higher speed 40kfps upscaled. Curious what effect it would have on resolution.

I bought a couple of these Stratus LED units with the reflector. I havenít put them through their paces yet but they are a reasonably cost effective solution if you donít mind making your own mounts to hold them.

Saw the tweet about the minor update but nothing pertaining to what the update was about.

Not sure without trying it but you might be able to go into the Custom Color Matrix menu and alter settings there. Otherwise software strip the color.

Could you keep the link to the builds in the original posts when posting new updates? ;) It makes it easier to keep track of things for those of us who are still using Balena Etcher to update.

Any time frame on enabling the audio trigger for things like gun shots etc?

It did some new stuff with up to 40.000 fps. What a shame that there's no 100.000 fps option anymore :(

By the way: I don't know why (maybe the new software?) but the image quality looks like it suffered a lot in comparison with my older videos.
at 20.000 fps I got again some strange maze like artifacts :( I don't know why this happens...

Look at around 5:30 ... it looks like there's a veil in front of the picture and the object just rarely shines through.

Is that a speed booster that you install first on the cam or just a lens adapter?

Did you try a hard power down? I had the same thing happen when I updated the firmware. Power down holding the button for 4 seconds or longer then power up.

Since nobody answered this, itís in the current .4 Voyager release.

The shutter speed can be set regardless but the issue is the amount of light required. David said figure 7 Lux per FPS. I presume thatís at 360 deg shutter so even way more light at higher shutter speeds. As long as the file remains on github, you can use it. Download it now and save it in anticipation of getting a camera. Iíll check and confirm tomorrow.

The idea is to adjust your back-focus correctly for your lens and not have to bother it. Then use spacers to get the depth of focus you need for a particular shot.

I've got one of the Stedi-Stocks that I use for a thermal camera. It would probably work well for wildlife work, be easy to home brew one as well.

Wanted to chime in and keep the info in one thread. I bought a couple of the StratusLED V2 units with the parabolic reflectors. Made a quick measurement with a no name light meter for a general idea: @1M 60,000 Lux, @2M 17,000 Lux, @3M 7000 Lux, @4M 4000 Lux, I rounded down. Didnít have a second connector to wire them both up. Going to work on a simple housing and mount idea next.

And per another thread, David said to figure on 7 Lux per FPS as a rough calculation. Iím a little curious as to the relationship to shutter speed as well.

Looks like there is some good general photography  knowledge for noobs like myself.

Crossbow bolt @ 9000 and 14100 fps

Are you recording in H264 or CinemaDNG?
