安卓录制视频不录制外界声音

I recently started making some programming videos where I’m part screencasting, and part there’s a little icon of me showing up.

我最近开始制作一些编程视频，其中一部分是我的屏幕录像，一部分是我的小图标出现。

I really dislike programming videos where you don’t see the person talking. I think it makes things more human.

我真的不喜欢在没有看到对方讲话的情况下对视频进行编程。 我认为这使事情更加人性化。

Since I started, I changed the setup quite a bit, and this post aims to describe how I do things.

自从开始以来，我对设置进行了相当多的更改，并且本文旨在描述我的工作方式。

I have a MacBook Air. I’m recording my videos using ScreenFlow. I started by using my iPhone SE to record my face, and as a microphone too.

我有一台MacBook Air。 我正在使用ScreenFlow录制视频。 我首先使用iPhone SE记录了我的脸部，也开始使用麦克风。

Then I switched to using my old Nikon J1 camera, much better quality but the problem was that it didn’t have a flipping screen, and one time I talked for 20 minutes without recording, and I didn’t realize it.

然后我转而使用质量更好的旧尼康J1相机，但问题是它没有翻转屏幕，有一次我聊了20分钟却没有录制，但我没有意识到。

Then to get a better audio quality I got a microphone, a Samson Meteor. Definitely a great mic.

然后为了获得更好的音频质量，我得到了一个麦克风，即Samson Meteor。 绝对是很棒的麦克风。

It has a built-in monitor where those earpods are connected, so I can

它有一个内置的显示器，用于连接这些耳机，所以我可以

1. hear if it’s recording correctly
   听听录音是否正确
2. immerse more into the video, it gives a nice isolation from the outside
   将更多内容浸入视频中，可以很好地与外界隔离

Once I decided to get “serious” I then got a DSLR camera, a Nikon EOS 200D. An entry level DSLR camera, but it has all I need: a flipping screen, and autofocus.

一旦决定“认真”，我就得到了数码单反相机，尼康EOS 200D。 入门级数码单反相机，但它具备我所需的一切：翻转屏幕和自动对焦。

The flipping screen is the things I was more interested in.

翻转屏幕是我更感兴趣的东西。

It also makes the background blurry in videos, which makes a nice effect.

这也会使视频中的背景模糊，效果很好。

I also got a microphone for it, the TAKSTAR SGC-598, which sounds awesome.

我也有一个麦克风，TAKSTAR SGC-598，听起来很棒。

I usually put it before the screen while recording me coding:

我通常在录制代码时将其放在屏幕前：

Then I got a few lights for when I’m recording in the evening or when the light is just not right. I don’t use them always. Here’s one:

然后，当我在晚上录制或灯光不正确时，我会得到一些灯光。 我不总是使用它们。 这是一个：

I also got a green panel for those nice recordings where you are into the video, but I never used them yet. Why? The simpler the process, the more videos I make. It’s like with blog posts.

我还为您在视频中录制的那些精美记录提供了一个绿色面板，但我从未使用过它们。 为什么？ 过程越简单，我制作的视频就越多。 就像博客文章一样。

So, my recording workflow until this morning was this: start a ScreenFlow recording to get the screen image and the audio from the monitor, and start the camera recording at the same time.

因此，直到今天早上我的录制工作流程是这样的：开始ScreenFlow录制以从监视器获取屏幕图像和音频，并同时开始摄像头录制。

Finished the video, I grabbed the SD card from the camera, and put it into the usb-c hub connected to the Mac, and imported the video into ScreenFlow. The audio track from the two videos helped me sync the 2 recordings.

完成视频后，我从相机中抓取SD卡，并将其放入连接到Mac的usb-c集线器中，并将视频导入到ScreenFlow中。 这两个视频的音频轨道帮助我同步了两个录音。

The problem with this is that videos last 30 minutes on the camera, so I had to re-start the video again (maybe there’s some setting, I didn’t look too much) and the SD thing was becoming a burden (the camera also has Wi-Fi download for videos, but it’s not very practical as well).

问题在于，视频在摄像机上的播放时间为30分钟，因此我不得不再次重新启动视频(也许有一些设置，我看起来并不过分)，而SD成为了负担(摄像机也可以下载视频的Wi-Fi，但这也不是很实用)。

The other day I was randomly searching “how to use a Canon EOS as a webcam” and I found .

前几天，我随机搜索“如何将佳能EOS用作网络摄像头”，然后发现了 。

You can read all the details there but long story short, I keep these 2 applications open:

您可以在此处阅读所有详细信息，但总而言之，我将这两个应用程序保持打开状态：

and my camera, connected via USB to the Mac, shows up as an option for video input.

通过USB连接到Mac的我的相机显示为视频输入的选项。

With this system I can use the DSLR camera as a webcam, which is pretty cool because that’s the best webcam I could ever find!

有了这个系统，我可以将DSLR相机用作网络摄像头，这非常酷，因为这是我所能找到的最好的网络摄像头！

I tried to also stream the audio along with the video, but I couldn’t, so I use the Samson Meteor microphone instead, with a pop filter. Bonus points for not having the big camera microphone covering parts of the screen. There’s a little delay between audio and video in the recording, but easily fixable.

我也尝试将音频和视频一起流式传输，但是我不能，所以我改用了带有过滤器的Samson Meteor麦克风。 由于没有大型摄像头麦克风覆盖屏幕的某些部分，所以有加分。 录音中的音频和视频之间有一点延迟，但是很容易修复。

The problem now is that the MacBook Air fans (2018, 16GB of memory, SSD, 1,6 GHz Intel Core i5) start and make a lot of noise. And it gets super hot, I think I’m pushing its limits too much by recording the screen, the camera input and the microphone all at the same time.

现在的问题是MacBook Air风扇(2018、16GB内存，SSD，1.6 GHz Intel Core i5)启动并发出大量噪音。 而且它变得非常热，我想通过同时记录屏幕，摄像头输入和麦克风来过分地限制它。

So for most videos I’ll switch to use the camera as a camera, rather than as a webcam. Or I’ll find a way to keep the MacBook Air either cool or far from the microphone so I can’t record the fans.

因此，对于大多数视频，我将切换为将相机用作相机，而不是用作网络摄像头。 或者，我将找到一种方法使MacBook Air保持凉爽或远离麦克风，以免记录风扇。

All still work in progress!

所有仍在进行中！
