Frames per second needed to watch AR operating system in action?

[FromMyColdDeadHand]

I see that there is a new Casio camera that takes pics at 1000 fps...


a maximum speed of 1,000fps (224x64), revealing detail that’s simply too fast for the naked eye to see. Additional high-speed frame rates include 480fps (224x160) and 240fps (432x320).


Is that fast enough to capture the details of what is happening in an AR operating system or a handguns slide movement? I'm thinking it isn't fast enought to catch BCG bounce or help with round feeding on a 1911.

Anyone have one of these casio cameras?

Check out this video

it shows BCG bounce

Interesting, looks like 1000Fps is enough to see what is actually going on

[Luke_Y]

It ought to be fast enough, but 224x64 is awfully low resolution.

[rob_s]

I noticed the resolution issue too. I am still thinking of pickin up one of these. If it's the camera I'm thinking of there's a video o line of a guy jumping over a grass patch recorded at all speeds showing how the resolution degrades.

At least I'll have the coolest avatar!

[JasonM]

I've messed with one (and an older version)...

the image quality sucks. I wouldn't pay for one.

YMMV of course

There are a lot of videos on you tube showing what a vid would look like at 1000fps. It looks like it will work but the resolution gets worse as the FPS goes up. This one will give an idea of what it would look like.

I wouldn't buy one - but that's because I work in video for a living and, I'm not going to lie, there are times when HD seems low rez to me. I couldn't work on 224x64 without going mad.

Agreed.

Some of the mid level SLR's out there have a "sports" setting on them, where they take a series of five photos (I think it's five) one right after another. You could totally capture what your looking for with this setting.

Since this forum is very much about quality of novelty of features, I have to suggest that you save your money, and buy a better camera that offers similar capabilities.

Good luck with your search!

Phantom Cameras, which shoot that 1000fps, and higher, rent for $2500/day.

I just bought a Casio EX-FH100 just because of the wide zoom and overall functionality. The High Speed video was just a bonus. The bolt bounce videos look like they could have been taken by this camera, however with detailed setup and lighting. The FH100 also has a great "Continuous Shot" mode for superfast "bursts" of pictures that helps with kids, sports, and other fast movement. I see this as finally using some of the true capabilities of the digital CCD.

I also have a Canon 40D DSLR as well and it can only take like 5 shots a second, and even if it had a multi shot burst mode (which I still doubt is fast enough) timing it to shoot bolt bounce would be pretty hard.

For only like $300 this is a great camera with a lot of capability.

Sounds expensive, till you think that at 1000fps that is 42 times more frames than a normal camera, so the effective price is $59.50 per day. :D

http://www.youtube.com/watch?v=U3JfGw8YfeQ

224 x 64 (1000 fps), 224 x 168 (420 fps), 448 x 336 (240 fps), 640 x 480 (120 fps), 448 x 336 (30-240 fps), 640 x 480 (30-120 fps), 720p (30 fps)

Maybe I'll wait a generation and hope the resolution doubles at least in the next camera.

That's exactly the one I was thinking of.

This review keeps scaring me away from the camera as it sounds like it's a mediocre camera outside of the high speed thing.

And they're really fun until you have a director that wants to roll it on everything and you have to find a place to save the ridiculous amount of data it captures. Now there was a fun rookie mistake.

I took some quick video of a bolt dropping from lock with my FH100 camera at 1000fps. The aspect is off and the quality is probably 20% poorer than straight from the camera because I have no idea how to use my editing software. Also, my lighting was crap and probably my close in focus as well. Regardless, you can easily see the bolt bounce.

Also, here is a minimally compressed (18) JPG taken with the same lighting just to show the macro capability of the camera.

I bought the FH100 based on this review as a wide zoom with fast operation and good quality. I had no idea about the high speed capabilities at first. I would trust a digital camera review site over CNET any day of the week :)

Here is some footage of a camera that shoots 1 million frames per second recording bullets impacts.

http://www.youtube.com/watch?v=QfDoQwIAaXg

[Yeti555]

I looked for the website for the camera in my last post.
http://www.kurzzeit.com/kameras.htm
1 Million FPS, but it can only store up to 100 frames at a time. That would still be a pain to get perfect timing.

Here's the specs from the site
-----------------------------------
High-Speed Video Camera HyperVision HPV-1
The Shimadzu HPV-1 High Speed camera offers up to one million frames per second :)
with a 100 frames memory. :(

It maintains excellent 312 x 260-pixel resolution at all recording speeds
to permit detailed analysis of high-speed phenomena.

Dedicated software in the control unit allows recording to start immediately
after performing a few simple settings. Recorded images can be saved in general
image formats such as AVI or BMP.


Basic specifications:
- Resolution 312 (horizontal) x 260 (vertical) pixels
- Frame storage 100 frames
- Lens mount Nikon F mount
- Color, gradations Monochrome, 10 bits
- Recording speed 30 fps to 1,000,000 fps
- External trigger input TTL (positive/negative), switch closure
- Trigger mode Set trigger point at any desired frame
- Recording format 10-bit dedicated format, BMP, TIFF, AVI

i know this is nowhere near the fps your talking about but i have a Flip ultra that records 720p @ 60fps. Now when recording my BCG on an over gassed carbine gas barrel and standard carbine buffer the cycle was caught in 5 frames starting when the bolt first moved and stopping when the bolt closed and re-chambered. Thats def. not enough to catch bolt bounce BUT believe it or not i did. I just recorded around 20 cycles and u just have to get lucky with the camera timing which you will. If u just want something to check if bolt bounce is present then the flip ultra will work but if u actually want to see the full motion of the bolt bounce u need 1000fps

For some specific reason, or simply because you used them as your basis for purchase and they validated what you wanted to hear? ;)

Not picking on you, just being specific. We obviously see this all the time here with "they told me on ar15.com it was good" kind of posts.

ETA:
I *want* to like this camera, so I'm really looking for good credible reviews and something that pokes holes in the numerous bad reviews I've found.

[Dennis]

Ouch! Comparing DPReview.com to TOS is just plain mean :p

I have bought several digital cameras over the past few years including DSLR's and I have found that DPReview.com has always been pretty accurate. In fact, most photo-geek sites are pretty honest since there are so many easily measurable metrics that don't really exist for AR's.

My comment about CNET is because that is a tech-geek site, not a photo-geek site.

More importantly, what bad reviews are you talking about? A quick Yahoo search pulls up the following reviews from serious photo sites, all of which are overall positive. (Photo-geeks can always find nitpicky problems!)

I did not buy this camera for high speed video. I wanted a super wide zoom with fast cycle time and this camera came up so I bought it. For less than the cost of a case of ammo I figured what the heck!

Funny, I found out about the Casio camera on Dpreview, which I haunt about once a week.

Dpreview is the heat when it comes to cameras. Most up to date and they actually run quality tests and do side by sides. Hardcore stuff that I don't know is replicated anywhere else.

cnet to me isn't bad, but dpreview will give you actual data to look at. Run a scene at different ISO levels, or at different lens focal lengths and then look at the resultant pics. No fluff.

All those P&S cameras seem like kludges to me coming from SLRs, so I am always disappointed in how they operate.

[Titleist]

We've got a camera here at work that does 10,000 frames per second. :eek:

Never bothered to take it to the range. :(

Yeah, I see my DSLR as similar to my Noveske 16" middy with T1, BC 1.0 compensator, BAD, BAD ASS, and attachable 3x magnifier or even a sighted in TR-24G. Versatile, fast, and easy to use.

I see Point & Shoots as more like one my J-frame backups. Easy to carry, but much more work to get good results.

Although, this new Casio is more like a G26 in comparison given it's enhanced feature set :D

As I said, I want to like the thing so I'm glad to see that the site withthe favorable review is well respected. I'm on my phone so I don't have links goths other reviews I saw but most were user reviews.

About 10 years ago those cameras used to run about $75,000. What do they cost these days?

[Titleist]

About 45K.
