video camera

Let's say the pellet is 1 cm, while the speed is 1500 feet = 45,000 cm / second. To see the position of the pellet in a snapshot it may only move .1 cm, so you would need to take 450.000 pics a second.

Then consider the resolution. You can't manually move the camera reliably to follow an object moving 450 m / second. So let's say your picture needs to cover a static area of 450 x 100 m to see the pellet for one second. That's 45,000 square meter, that's 45000000000 square centimeter. Allow for 10 pixels for the image of a pellet, so the camera would need to record 450,000,000,000 pixels on each pic.

I don't think you can buy this for USD 1000.

spin the response a little differently...

If your goal is to provide smooth slow motion playback, then a *fast* frame rate (and shutter speed) is required. There's no need to recreate the wheel... Go to youtube.com and search using "slow motion pellet gopro". Camcorders and cameras that capture at 30 fps (or less) will not provide the useful slow motion playback you are looking for. The GoPro Black might do what you want.

Industrial motion analysis video capture is not usually a consumer camcorder item. Photron, Fastec, NAC Image Technology and several others make such cameras that usually do not have any internal recording capability, but connect directly to a computer for the captured video storage. I believe their entry level price is around $40,000 (new) and lenses are extra...
