3. WHY DO WE NEED TO RECORD ?
 Screenshots are great, but sometimes you need to create a video
recording to really get your point across.
 Put together a video tutorial or just capture a problem you’re
having so you an demonstrate it later.
 This process gives you a video file, which you can do whatever you
like with. Upload it to YouTube or email it to a friend.

4. WINDOWS
 Windows doesn’t include a built-in tool for creating desktop
recordings.
 The simple way is to use VLC to record your desktop.
 For more advanced screencasts, we recommend OBS (Open
Broadcaster Software).

5. VLC MEDIA PLAYER
 It’s a Swiss army knife that will allow you to quickly record your
desktop without installing anything else.

6. OBS (OPEN BROADCASTER SOFTWARE)
 OBS is more suitable for more
advanced screencasts.
 It’s very powerful, free, open-
source tool.
 Insert watermarks, embed a
video from webcam while
capturing your desktop.
 OBS is widely used for video-
game-streaming on Twitch.tv.

7. MAC OS X
 Mac OS X has a built-in screen-recording tool. It’s one of the many
useful functions hidden in QuickTime.
 For something more powerful, you may want to try Open
Broadcaster Software (OBS). It’s not just for Windows — it works
on Mac, too.

8. QUICKTIME(MAC)
 Open the QuickTime application.
 Click the File menu, select New
Screen Recording. You can record
audio from microphone too.
 Click the Record button to start
when you’re ready.
 Click Stop when you’re done.

9. LINUX
 Linux has ffmpeg and other commands from Linux distribution’s
package manager.
 recordMyDesktop is also a good program, which you can install
install from the Ubuntu Software Center.
 If you want something more powerful, try Open Broadcaster
Software (OBS). It’s available for Linux as well as Windows and
Mac OS X.

10.  Launch recordMyDesktop.
 Use its options to choose
video and audio quality
levels.
 This tool can record your
entire desktop or just a
small portion of it.

11. ANDROID
 Android allows you to capture a video of your device’s display and
save it as an mp4 file on Android 4.4 and still on Android 5.
 To do this, you’ll need to connect your Android device to a PC and
use the adb command.
 Apps on your phone can’t start recording your display on their
own — this prevents apps from initiating a recording to capture
you entering sensitive data.

12. ADB SHELL SCREENRECORD (ANDROID)
 Connect your Android device to
a PC with a USB cable.
 Use the “adb shell screenrecord”
command to start recording its
display.
 If you have a rooted device, you
can also initiate a screen
recording with an app on your
device — but that app needs
root permissions.

13. IOS
 There’s way to record an iOS device’s screen, required a Mac running OS X
Yosemite and an idevices running iOS 8 or newer.
 This feature is only available for Mac users.
 You can live-stream your desktop instead of recording it too with OBS.
 You can even live-stream your desktop straight from VLC!

14. QUICKTIME (IOS)
 Use the QuickTime application to
capture its screen.
 Just select “New Movie
Recording” instead of New Screen
Recording.
 Click the menu button, and select
the connected iOS device instead
of your Mac’s built-in webcam.
