Why OBS? It's free and Twitch streamers have proven it is quite configurable and reliable.
Configuration
- Download OBS (Mac, Linux, Mac) from: https://obsproject.com/download
- Install and Launch OBS.
- Create an Scene
- Add Display Capture and Audio Capture
- Open the
Settings
window and selectOutput
, thenRecording
, selectmp4
- Still under
Settings
,Hotkeys
tab, I recommend adding a hot key to start and stop recording. - Close
Settings
window.
Recording
To record, I recommend maximizing RStudio in Mac, then select the OBS window, switch back to RStudio and use your start-recording hot-keys, record the video, then finish with stop-recording hot-keys that you defined when configuring OBS.
Tips
Intro Screens: It helps to add a intro screen. We createed one with RMarkdown that we open in a browser with each video and maximize in full-screen. Then we start recording on the intro screen and then swipe (in Macs) to the actual content you want to present.
Noise Filteers: I also recommend playing with noise filters, depending in microphone sometimes is bettter sometimes worse.
Hit the settings icon in the Audio Input Capture
bar and select Filters
. Try adding Noise Gate
and Noise Supression
,
and play around with the sliders, you will have to record a video, change the filters, then retry until you get something that you like.
