content: It's time to get a camera with a faster frame rate and also to get a new copy of Vegas. My version only handles 800X600 which is why my videos are formatted so poorly. I have no skills or knowledge when it comes to cameras. If I can select auto and push record, I am golden.Looking for something low cost. Under $500 would be great. 120 fps seems to be the norm now.Any camera buffs care to chime in?

content: Sure. The camera would be mounted stationary and used indoors only. No harsh vibrations or wide temperatures. I would like to be able to capture an arc event like this.

content: Take a look at Casio. They have a number of digital camera models with very high speed modes, up to 1200fps! The higher the frame rate, the lower the resolution (at 1200fps you're looking at postage stamp size video, something like 220x70), but that can still be useful.

content: Have you seen the Sony RX100 IV ?It is probably the best consumer high speed camera (and all around compact camera) at the moment: it shoots 1000 frames per second in FullHD!It costs 1000$ though.Greetings

content: I plan to slow it down for youtube. I have been watching some videos at the 120 fps and it does not seem all that fast. A few of you know I have been damaging a few hand held meters. I would be interested in being able to see how just how the arc travels across the circuit board. Maybe the 1000 fps is more in line. Almost need a rental place so I can try a few out.

content: I think with 1000fps cameras you will need to invest in lighting as well. Not as much light will be hitting the sensor in <1ms...

content: Quote from: hayatepilot on November 02, 2015, 01:11:03 pmThat Sony is fast, but not quite as fast as you said. Its spec. page says it offers:3840x2160 (30p/25p/24p)1920x1080 (60p/60i/50p/50i/24p)1280x720 (30p/25p)1824x1026 (250p/240p)1676x566 (500p/480p/250p/240p)1136x384 (1000p/960p/500p/480p)800x270 (1000p/960p)That's still quite an impressive bit rate coming out of the sensor, through the compressor, and into memory. I didn't see mention of what kind of storage it needs to keep up.

content: Quote from: joeqsmith on November 04, 2015, 03:07:08 amSome cameras don't adjust the exposure after you start recording, and even if they do, they probably don't adjust fast enough for an arc. You'll probably need to use a manual exposure setting.

content: Quote from: hayatepilot on November 02, 2015, 01:11:03 pmI finally pulled the trigger on one and ended up with the Sony. The camera can only record for a few seconds so I think I need to modify my transient generator to output a trigger pulse for the camera. The camera seems to support something like this but I can't find very much information on it.Lighting even at the higher speeds does not seem to be much of a problem. I tried it with some arcs and it does pretty good. Looking forward to seeing some slow motion destruction....
