It's even better if you can make the video source itself smaller. This will reduce the CPU time required to encode the video. If you don't need a high resolution, try scaling the video down before it is encoded (enable scaling on the input page). So you might want to switch to uncompressed audio, and re-encode it afterwards. Use uncompressed audioĪudio is much smaller than video, so it doesn't matter as much whether it's compressed or not. There are also GUI programs that can do this, for example Handbrake. You can use the avconv/ffmpeg command line tool for re-encoding. It's a good idea to choose a fast profile (which will result in large files), and afterwards re-encode the video with a slower profile to make the file smaller. You may have to install extra packages to get H.264 support (for Ubuntu: sudo apt-get install libavcodec-extra-53 libavformat-extra-53). The H.264 codec is by far the fastest one, especially if you pick the 'superfast' or 'ultrafast' profile. Some video codecs are really efficient, and other are really slow. This article is just a list of things you can do to improve the performance of SimpleScreenRecorder (or in some cases the computer in general) so you can record at a decent frame rate. Reduce the frame rate of the application that you want to record
