How to do screencasting (desktop recording) with high quality audio and video?

The solution I like is to use SimpleScreenRecorder. Here's how I did it:

How to build and install latest SimpleScreenRecorder from git?

My solution turned out to be simple to follow once I got the help I needed. I hope others can follow the dev's git instructions now.

Here's more info on SSR:

SimpleScreenRecorder is a Linux program that I've created to record programs and games. There were already a few programs that could do this, but I wasn't 100% happy with any of them, so I created my own.

My original goal was to create a program that was just really simple to use, but as I was writing it I started adding more and more features, and the result is actually a pretty powerful program. It's 'simple' in the sense that it's easier to use than ffmpeg/avconv or VLC, because it has a straightforward user interface.

Features

  • Graphical user interface (Qt-based).

  • Faster than VLC and ffmpeg/avconv.

  • Records the entire screen or part of it, or records OpenGL applications directly (similar to Fraps on Windows).

  • Synchronizes audio and video properly (a common issue with VLC and ffmpeg/avconv).

  • Reduces the video frame rate if your computer is too slow (rather than using up all your RAM like VLC does).

  • Fully multithreaded: small delays in any of the components will never block the other components, resulting is smoother video and better performance on computers with multiple processors.

  • Pause and resume recording at any time (either by clicking a button or by pressing a hotkey).

  • Shows statistics during recording (file size, bit rate, total recording time, actual frame rate, ...).

  • Can show a preview during recording, so you don't waste time recording something only to figure out afterwards that some setting was wrong.

  • Uses libav/ffmpeg libraries for encoding, so it supports many different codecs and file formats (adding more is trivial).

  • Can also do live streaming (experimental).

  • Sensible default settings: no need to change anything if you don't want to.

  • Tooltips for almost everything: no need to read the documentation to find out what something does.
