you know, I did OK in my back yard. So this is Henry from MinutePhysics and he's about to do a

你知道，我在我的後院做得很好。我是MinutePhysics的Henry 他要做的是...

bullet time exhibit here at the US Space and Rocket Center.

(Computer voice) 3..2..1.. Like your style!

So what did we learn here.

那麼我們在這裡學到了什麼。

On the last video we learned three things. First of all the radius from the center

在上一個視頻中，我們學到了三件事。首先，從中心出發的半徑

of all the cameras has to be exactly the same. Secondly the angular offset of each

的角度偏移必須完全相同。其次，每臺攝影機的角偏移量

camera needs to be the same so it doesn't look like it's jittery. And third the exposure

相機需要相同的，所以它看起來不'的抖動。第三，曝光

and white balance needs to be the same which requires similar devices. This time our setup

和白平衡需要相同，這就需要類似的設備。這次我們的設置

was even better, and that means we can learn more. The first thing that we learned is that

是更好的，這意味著我們可以學到更多的東西。首先，我們學到的是

inconsistent lighting is a problem. So there's a flash, there's a flash,

不一致的照明是一個問題。所以有'的閃光，有'的閃光。

there's a flash. So one bad thing about this setup is you get shadows

有'的閃光燈。所以這種設置有一個不好的地方，就是你會有陰影。

at different points. So if we had it to do over again we'd probably bounce some light up into those shadows.

在不同的點。是以，如果我們有它做一遍，我們'可能會反彈一些光到這些陰影。

Secondly the cameras have to be pointed at the exact same spot. If you'll

第二，攝影機必須指向完全相同的位置。如果你'll

notice on the left, the dot on the carpet kinda jumps around and it throws your eye off.

注意到左邊，地毯上的點有點跳來跳去，讓你的視線偏離。

But on the right, Henry went in and corrected this for every single clip in the video,

但在右邊，亨利進去對視頻中的每一個片段都進行了糾正。

which made for a nice smoother turn. So a big thank you to the

使得轉彎更加順暢。所以非常感謝

US Space & Rocket Center for letting us goof off at your Math Alive exhibit. If you want

美國太空與火箭中心讓我們在你們的 "數學生活 "展覽上傻了眼。如果你想

to subscribe to Henry's MinutePhysics channel check him out right here. If you want to subscribe to my channel

要訂閱Henry'的MinutePhysics頻道，請在這裡查看他。如果你想訂閱我的頻道

I'll do what Henry's doing.

我'會做亨利'的工作。

Get it?

明白了嗎？

It's like bullet time in my chair. Anyway it's 2am. It's probably

這'就像子彈時間在我的椅子。反正現在是凌晨2點。它可能

way more funny to me. I have another channel. You may or may not know that.

更有趣的方式給我。我有另一個頻道。你可能會或可能不知道。

It's called Funner Every Day. This week I have a question for you on it. I'm making

它'叫Funner每一天。這周我有一個問題要問你。我在做

posters, it involves lasers and cats. But I have a question as to what words need to go on there.

發帖人，這涉及到脈衝光和貓。但我有一個問題，就是那裡需要寫上什麼字。

I'll leave a link somewhere. I'm Destin, you're getting Smarter Every Day.

我會留下一個鏈接的地方。我是Destin，你每天都在變得更聰明。

Thanks.
