How much space do 340.000 FPS take up?
[QUOTE=Antimuffin;50728093]How much space do 340.000 FPS take up?[/QUOTE] I'm not sure the actual size but they said 5.1 seconds produced 19 hours of footage.
Are you okay man? I'm worried for you.

[QUOTE=StrawberryClock;50728105]I'm not sure the actual size but they said 5.1 seconds produced 19 hours of footage.[/QUOTE] probably only a few GB considering the low resolution

[QUOTE=Antimuffin;50728093]How much space do 340.000 FPS take up?[/QUOTE] Not as much as one would expect, I'd wager. The resolution drops proportionally to the framerate.
[QUOTE=Antimuffin;50728093]How much space do 340.000 FPS take up?[/QUOTE] IIRC the buffer on those cameras are at something like 96GB, so it likely fills that up during those 5 seconds of recording .

Makes me wonder if it'll do double the fps with half the resolution. 680,000 fps you'd make a killer video for things like gas igniting or bullets crashing
congrat on not being crazy

Pyrex these days is almost exclusively tempered glass. Well their non labware stuff is. I'd like to see them do this with borosilicate as a comparison. Borosilicate glass isn't under internal tension the way tempered glass is. So when it breaks small pieces just fall off. It's supremely boring by comparison, but it's interesting to see the actual safety benefits first hand. Borosilicate is substantially more resistant to thermal stress, but is slightly easier to break it with physical impacts. The old Pyrex stuff is primarily borosilicate vs the modern tempered soda-lime. For anything not being thrown into an oven, such as mixing bowls, measuring cups, or drinkware, tempered is definitely better. It will (should) never be subject to the temperature extremes needed to break it, and it's far more durable when you do inevitably drop it. With that said, having a tempered glass baking pan explode in my hands, I can say that I will gladly pay the extra not to have to deal with that shit ever again. Pans from the 60s might have some chips in them, and the new ones are more expensive, but if you buy one, you'll never need to replace it unless [i]you[/i] break it by dropping or slamming it. Even if you do drop the thing, there is a very good chance that you will just take a chunk out of one of the handles. If that happens, you can just grind it smooth instead of replacing it. While it is rare for tempered to explode, I really have no desire to pull glass splinters out of my ankles ever again. It might never happen to me again. It could also be my face. I have no incentive to find out.

Yeah. Tempered glass can be 'baking safe', but it's still possible for it to break in that way because of repetitive stress microfractures. You are probably more likely to break borosolicate, just because people do tend to drop shit. The difference is that when it breaks it won't throw razor sharp fragments all over the place, and it will pretty much never ever under any circumstance break while you are holding it. It breaks when you drop it, and that's pretty much it. Tempered can explode while you are holding it. [editline]17th July 2016[/editline] Oh. Forgot to mention. If you are doing something with retarded amounts of heat, well above and beyond what you will ever see in a kitchen, the best stuff is fused quartzware. This is getting into top end labware. The thermal expansion of that stuff is minimal at best. It's functionally immune to thermal changes outside of brutal laboratory conditions. It's completely impractical and overpriced for anything kitchen related. It's like 150 USD for a 500mL beaker. If you need it, there is no substitute, but you have to really need it before it becomes practical.
how does the camera even get that much light on the sensor for how fast the shutter speed is
[QUOTE=Glitchman;50729360]how does the camera even get that much light on the sensor for how fast the shutter speed is[/QUOTE] Must be a huge ass sensor then.

[QUOTE=Glitchman;50729360]how does the camera even get that much light on the sensor for how fast the shutter speed is[/QUOTE] They can't film indoors (not without some serious lighting gear) because slowmo takes so much light.

Yeah, that's absolutely what I'd considered cheating :v: You couldn't record, say, a bullet traveling through the air with that technique, you can only record laser pulses. It's more of an approximation technique than true high speed recording, because laser pulses can be repeated very accurately as many times as you want until you have the result you need.
