here to talk to you about alternate frame rates,

今天我們來講一下交替幀率，

specifically frame rates up to 60 frames a second.

尤其當幀率達到每秒60幀。

As Freddy is running, you´ll see his hands are moving and they are blurry,

當Freddy跑步時，您可看到他的雙手在移動，且非常模糊，

at 24 Frames per second.

此時幀率為每秒24幀。

The jump rope is moving very crisp and clear, at 60 frames per second.

跳繩移動非常清脆響亮，幀率是每秒60幀。

Why would you use something, up to 60 frames per second? Well...

您為何要使用高達每秒60幀的幀率呢？

..the same reason why you would use different aspect ratios,

其中原因跟您使用不同寬比一樣，

different color correction.

也和使用不同的較色一樣。

Or maybe shooting it in black and white.

或可能在黑白色中拍攝。

It´s all changing the form of what you´re doing,

它都在改變您的活動形式。

And by changing the form, you´re hopefully

一旦改變了形式，您便有望

also affecting the way your content is received.

改變您的內容被接收的方式。

60 frames per second has a very specific look,

每秒60幀有一個特定的外觀，

because you have, well, 60 frames per second.

因為您的幀率達到了每秒60幀。

It´s a little bit smoother, wait, is this in 60?

更平滑了，等等，這是60嗎？

Is this in 60?

這是每秒60幀嗎？

Because look at that!

因為看看那個！

Normally something like this, in 24 frames per second,

正常而言，在每秒24幀，

would be sort of smeary, motion blurry, what have you,

圖像會比較塗污、模糊，

but here, haha,

但這裡，哈哈，

every moment, every weird hand movement I´m making right now

每個移動，我現在正在做的每個奇怪的手部移動，

is captured in excruciating detail.

都捕捉得細緻入微。

60 frames a second is great,

每秒60幀太棒了，

for getting the sort of motion you get in fast scenes, in fight scenes,

可以捕捉快速場景、打斗場景，

car chases, anything that has very fast motion.

或追車等特快運動中的運動畫面。

You probably won´t notice, 60 frames a second,

您可能沒有注意到，每秒60幀，

in something like say a big, long, steady landscape shot.

有點像一個很大、很長且穩定的空鏡。

But it has an effect in the way motion is seen,

但它會影響人們看待此動態的方式，

elsewhere.

在其他地方。

Video Game High school is actually a show, where we used a split frame rate,

Video Game High school（電子遊戲高中）其實是一個表演，我們使用了拆分幀率，

where all the stuff happening in the real world, we shot at 24 frames per second,

我們用每秒24幀拍攝了真實世界，

and everything that´s happening inside the video game, we shot at 48 frames per second.

而用每秒48幀拍攝了電子遊戲中的場景。

So the idea was, with 48 you had more

其中的想法是，用48，

of a video game-y smooth look.

您會獲得電子遊戲般的平滑外觀。

This was a really easy way to distinguish the difference between

這是區分電子遊戲世界與真實世界的

what the video game world was and the real world.

一個簡單方法。

Normally when people have done this, with things like color correction,

正常而言，當人們這麼做的時候，有了較色，

aspect ratio, for The Matrix for example, right?

寬比，比如以《黑客帝國》為例。

Everything in the real world of that movie is blue,

在電影中，真實世界的一切是藍色的，

and everything inside the matrix is green tinted.

但矩陣中的一切卻是綠色的。

We didn´t want to do something so drastic, like with color correction,

我們不想用這麼衝突性的方法，比如使用較色，

so we decided to evoke that difference visually

所以我們決定視覺性地凸顯此差異，

by changing up the frame rate.

通過改變并提高幀率。

There´s like a new generation of viewers,

新一代的觀眾，

viewers who are sort of more used to things at a higher fame rate,

更適應更高幀率的事物，

things like video games, which might play at 60 frames a second.

比如電子遊戲的幀率就高達每秒60幀。

And you get a lot of benefits.

您會獲得大量好處。

Like take for example, the sort of shot of a car wheel, spinning.

比如，車輪旋轉的鏡頭。

At 24 frames a second in a lot of movies,

在很多電影里，在每秒24幀，

the car wheel starts to spin but then it looks like it´s starting to spin backwards.

車輪開始旋轉，但然後看起來車輪開始往後轉。

It´s kind of a weird effect.

效果有點奇怪。

A helicopter blade, anything that´s sort of fast and spinning.

一個螺旋槳翼，任何快速轉動的東西。

At 60 frames a second at higher frame rates gets you around that,

在每秒60幀或更高，方向弄對了以後，

by getting the direction right.

鏡頭才會弄對。

24 frames a second is great but it also has these weird motion artifacts,

每秒24幀很棒，但也有一些奇怪的人造運動，

that we´ve now, at this day and age, have come to accept,

現在，在這個時代，我們開始接受，

because that´s the way movies always have been,

因為那是電影一直以來的呈現方式，

but that doesn´t mean that´s how movies always have to be.

但並不是說電影始終要那樣。

And the question really, at the end of the day, comes to:

歸根結底，真正的問題是：

If you like that look and if that look serves the story that you are trying to tell.

如果您喜歡那個外觀，如果那個外觀可呈現您的故事。

If there´s action, and even if you don´t end up liking the look

如果是動作片，技術您最終不喜歡

of 60 frames per second,

每秒60幀的外觀，

I always recommend shooting at a higher frame rate,

我經常推薦以更高的幀率拍攝，

or even double your frame rate,

或甚至將幀率翻倍，

just because if you ever wanna do a slow motion effect,

僅僅是因為如果您想有個慢動作效果，

you can always just have that there,

您總可以使用那個幀率，

and have that...ehm...ehm...ability to go into slow mo.

擁有進入慢動作的能力。

I like using higher frame rates for things that are action oriented,

對於動作場景，我喜歡用高幀率，

or are very quick moving,

特快的移動場景也是，

you know, i think that the look of it is a very realistic look.

因為我覺得那樣一來，外觀會非常真實。

You know, I think it starts to fool your eye

我覺得它開始欺騙您的眼睛，

into looking at what you´re seeing as something

當您觀看某物時，

that´s sort of no longer through the lens of like cinema,

它好像不是通過攝像機鏡頭，

but more sort of a real life, look at something.

而是在現實生活中觀看某物。

And what I found is, that a lot of times it helps,

我還發現，很多時候，它會非常有用，

unless you´re doing like a more realistic Vlog, or something

除非您正在做更現實的視頻播客或其他東西，

that is a little more documentary style.

因為那更像紀錄片。

It puts you in there a lot more,

作為觀眾，它更能將您放入場景，

as a viewer, than compared to something like 24 frames a second,

而相比于每秒24幀，

where you´re like, oh this is clearly a movie.

您會覺得，哦，這就是一個電影。

So what´s cool about YouTube enabling 60 frames a second is,

對於YouTube，每秒60幀非常酷的地方在於

again, it opens up more of a palate,

對於一名創意者，

in terms of what you as a creator can do.

它提升了您的品味。

You know, for capturing game footage, if you're doing game commentary,

撲捉遊戲片段時，如果您在做遊戲評論，

or any sort of video game stuff.

或任何與電子遊戲相關的東西。

It allows you to capture things at a very smooth frame rate,

它可讓您用非常平滑的幀率捕捉鏡頭，

and really play back at exactly what you´re seeing.

可真實呈現您看到的一切。

If you´re doing live action stuff, you´re working with cameras,

如果您在做真人動作場景，您在用攝像機，

you´re working with....ehm...ehm..shooting things,

您在用...在拍攝東西，

then it allows you to have another option,

它會給您另一個選擇，

in your big palate of tools,

讓您擁有更多的工具，

in terms of how you want to express your story,

來呈現您的故事，

your image, and what you wanna get across in your videos.

您的圖像，以及您想在視頻中呈現的一切。
