content: Only 3 seconds of recording is allowed at 1200 fps, but when recorded at this very high frame rate it takes 2 minutes to play at 30 fps. Here's some videos I filmed with it.Note that the video is always recorded in landscape mode, so I had to use FFMPEG (a command line video processing freeware program) to rotate them 90Deg CCW so that they are properly oriented when played.While this thread opening post only has 2 videos in it, I plan to upload more of these 1200fps videos to Youtube and post them in this thread.

Presumably you need plenty of light, can't imagine it's very sensitive at that frame rate?

So I turned my camera to the side for this vertical phenomenon (a flame) I recorded, but unfortunately the camera doesn't have a way to set orientation in the recorded video, so I then used FFMPEG to correctly rotate the video. Not only does it look better this way, it also means that the phenomenon won't but cut off by the top and bottom of the frame.I also have other videos I've recorded with this camera, that are in portrait orientation, either because that made sense for the subject being filmed or because orientation wansn't that important for the subject being recorded.As for ISO, yes at this high speed, ISO must be quite high, or else you must be using a very bright light to illuminate the subject. The 2 videos I recorded here with the lighter flame were at ISO 800. As you can see, the flame looks good but everything else is massively underexposed.

content: The videos looks good.I thought about joining the kickstarter for Chronos but the more I dug into it, I just didn't see it doing much more for me beyond the 1000fps.

content: I do a lot of high speed video at work and find this program very useful for getting to what I want and applying various corrections and filters-http://www.virtualdub.org/indexBe happy you can't go a lot faster- video at several thousand fps needs a lot of light. Sometimes I think shooting on the surface of the sun would be about right.

content: Here's a 1200 fps video I recorded of a humming bird taking off at flying away. This took less than a second in real-time.
