每秒12万帧看水下爆炸

Underwater Explosions at 120,000fps - The Slow Mo Guys

哈喽!大家好!
Hello there!
我是 Gav.
I’m Gav.
我是 Dan.
I’m Dan.
我们是慢动作兄弟。我们今天要用
We’re the Slo Mo Guys. And today we’re gonna use a
超高速摄像机来观察
very fast camera to look at some
水下爆炸的情况。我们会用到
underwater explosions. We’re gonna use these little
一些型号为m1000的小爆竹。把它们粘在
bangers m1000’s, stick them in so they
鱼漂上,这样就能让它们浮在中间,
float so they sit in the middle cause
否则,它们就会浮在水面上
they actually just rise to the surface otherwise
我们之前有试过一次但是
yeah we once tried this before but
之前用的摄影机捕捉不够快,
with the old camera wasn’t fast enough
只能达到2500帧/s。
yeah we were trying to film it at 2500 frames a
所以今天我们要用28000帧/s的高科技。
second. Today we’re going to do 28,000
这妥妥的能让我们观察到
frames a second. That’s should really open our
肉眼捕捉不到的现象。
slow mo eyes into what’s really
虽然我们还觉得
happening and maybe even if we’re feeling
这个速度太慢了。好期待!
cheeky go little bit slower. Looking forward to this.
开始吧!我来点。好。
Looking forward to it. I’m a get a lighter, alright?
动作危险,请勿模仿。
Don’t try this at home, either .
能看到现在炸药在水里形成了一个小小的水球。所以我
Now, the explosive creates a little sphere so I’m
会把焦点集中在
going to focus on where the front of
水球的移动而不是
that sphere is going to be, and not on
小炮竹的本身,所以在一开始的时候
the banger itself so at the beginning it’ll
可能会对不上焦,我尽量吧。
probably be out of focus but it’ll come into focus hopefully.
(爆炸声)
(Explosion sound)
嘿嘿嘿。
Hehe!
帅!
That’s cool!
有点臭,闻起来不错嘛,好了么?
Little funk, smells good, ready?
哇哦,超级成功!这个就像是
Woah! That’s very good! Oh! It’s like that the
光线的收缩和扩张。感觉
light comes back as it comes in. Like all
爆炸产生的能量被
the explosive mass is being
热量压缩。
recompressed into heat.
酷!这次,我们要把环境弄暗一点儿。
So cool! Okay, I’m going to expose it really dark.
这样就能看清楚爆炸中的小细节。
So you can see more detail in the explosion.
刚才太亮了。
That first one was pretty bright.
(爆炸声)
(Explosion sound)
离你的手太近了。
Kinda close with your hand
还行,没事儿,我之前就这么干过了。
there… naa, its fine, done this before. It’s actually quite
水面下引线的距离其实很长。
long way a fuse inside this is. Yeah once
恩一旦它消失了。。
it disappears in this is where your
那就是在引线引爆鞭炮时你手放的地方。
hands on it when the fuse hit the banger
很好。看这个,在这个极短的瞬间里,
That’s fine. Look at that, that one little moment in time
尽管它持续的时间是那么短,但还是酷毙了。
is so cool that last for such a small
而这只是个鞭炮,一个小小的鞭炮而已。
amount of time. It’s just a banger. One lil’ banger.
哦,朋友。这里面有一帧的画面,看起来就像蘑菇云。
Aw, man. There was a frame and that looked like a mushroom cloud.
我想说那就像在中心发生了核爆一样。
I was gonna say it looked like a nuke in the middle of there.
我们现在是512X320像素的画面,
we are now at 512 x 320 pixels which is
这糟糕透了。
shockingly bad. Um, sort of lower than
恩,在某种程度上比标清还差。。
standard def bad but the upside is
但这上面是420,000帧每秒。
420,000 frames a second so slight issue
所以这对高速摄影来说只是小事情。。。
with the filming in high-speed and
我们现在要停下来了。
having to stop…
啊——嚏!
ATCHOO!
你还好吗?
You all right?
该死的!
Bloody Hell!
在高速摄影之下一切都是黑的,
only you in high-speed so everything’s
但我也把镜头的光圈缩小了很多,
dark but i’m also stopping down the lens
恩。这就是我能在屏幕上看到的。。。
so much that, uh. This is what I can see on
就算你使劲去看,
the screen if you’re struggling to see
上面也是什么都没有。
it’s absolutely nothing
所以这是个反复试验,
so this will be trial and error as in
为了找到准确的那一帧
the exact framing
不知道我们得到它了没有。
no idea if we got that. The thing is that
但重点是屏幕的刷新频率太差
there were the refresh rate on that
所以我什么也看不到。
screen is so bad I didn’t see anything
所以也不知道我们是否摄下来了。
on it so i have no idea whether we got it yet
努力去找到它吧。
Struggling to find it. It’s only a split second but
那只是几分之一秒,
Is that the amount of footage you’ve
但那是你设置连拍的数量吗?哇,我们找到它了!厉害了,它被完美地拍摄在画面上。
selected? Whoa! We got it! Awesome, that’s perfectly in frame!
*激情的音乐*
*Dramatic Music*
*慢镜头水下爆炸*
*Slo-motion Underwater Explosion*
很酷。太棒了。这真是太厉害了。
Very cool. That was wicked. Very very cool so it
看起来我们永远不可能
seems like we’re never gonna be able to
看清这整个爆炸的所有细节,
see the entire explosion in full detail
但只能看到
but not only going to be able to see
它的最初始过程
either just the very beginning or not
或者非初始过程和一些剩下的部分。
the beginning and some of the rest of
对,所以我们再制造一些
Yeah, so we’ve taking different
不同的爆炸,
exposures we’ve got like different
看看在不同的阶段
stages of the explosion there correctly
爆炸过程是如何正确运行的。
exposed
好,其实我也很有兴趣看看
ok so i’m actually quite interested to
当爆炸发生时
see what the surface of the water does
水面上会发生什么。
as the explosion happens so we’re going
所以我们定位到位置一,水面下的几英寸,
to position one a few inches under and
在这里用更加一般的帧频去拍摄。
do it sort of more normal frame rate
一般帧频是什么?这并不一般。
What’s normal frame rate? That’s not normal frame rate
在这个摄像机里面是。。
On this camera it is

nice
很好
very nice
*激情的音乐*
*Dramatic Music*
*慢动作爆炸*
*Slow-motion Explosion*
*帧频变化*
*Frame rate change*
*帧频变化*
*Frame rate change*
好吧这个水缸在另一个视频也出现了。
Well the tank survives another video
我不知道以后要怎么样搞定这个东西。它让人印象深刻。
I don’t know what we’re going to have to do to get rid of this thing. It’s impressive.
对,就算
yeah although the ink bundles are really pushing it to its limits. Yeah. right, right, right.
是啊。那真是疯狂。
Yeah. That was crazy
我喜欢看这些
I love seeing those capitation balls i’m not
我不确定那是个真空空间还是说
sure if it is just a vacuum or whether
这个来自鞭炮的化学反应其实
the reaction from the banger actually puts
把空气引入了这个空间然后再次把它封闭了,
air into there but it- it closes in again
而且以某种方式再次把里面的东西引燃。
and sort of reignites whatever is in there.
这很酷。它的原理也很有趣。
It is cool it’s also interesting how
因为引线本身也有
because the fuse contains its own
它自己的氧气来源
source of oxygen
即使它在水下,
even if it’s underwater you don’t need
你也不需要担心它的运作。它还是能正常引爆。厉害了。
to worry about it still good. It’s so cool.
我喜欢设定一些奇葩的帧频。
I love to establish ridiculous frame rates
好,希望你们喜欢那个视频,我觉得它很不错。
Well, hopefully you enjoyed that video I found that one fascinating!
请在推特上面帮我们顶起,

里面有不少视频。我穿着T恤。
and we got merch. I’m a T-shirt guy.
下个视频见!
so hopefully we’ll see you in the next video!
我流了好多汗。
I’m so sweaty.
要去洗个澡吗?
Care for a dip?
*恶心*
*Disgusted*
它闻起来总那么臭吗?
Always does it smell bad?
它闻起来总像——?
It always smells like –?
额,我的袖子在里面弄湿了
Ugh, I got my sleeve wet in it!
哈哈哈
Hahahaha
看你的表。
Watch your watch
啊耶
Ah yeah
我打赌这在慢镜头里也会很酷。
Bet that would have looked quite cool in slo-mo.
现在你告诉我了
now you tell me
我会再把它装满水,就为了再倒一次。
I’ll fill it back up just to do that again
