If you use OpenGL recording, you can check Limit application frame rate to make the application frame rate match the video frame rate. If you're recording at 30 frames per second, it doesn't make much sense to run the application that you want to record at 60 frames per second (or even higher). Reduce the frame rate of the application that you want to record This may allow the recorded application to run more smoothly, resulting in better overall video smoothness, even though the video frame rate may be lower. 60 to 30 FPS will have a significant effect on CPU usage. In most cases, the processing effort required to encode video is roughly proportional to the frame rate, as is the file size. (More YouTube resolutions here.) Reduce the recording frame rate For example, if you're going to upload your video to YouTube, and 480p is good enough, resize your window to 854x480. For example, if you're recording a game, you may want to switch it from fullscreen to windowed mode and resize the window so it matches the final video resolution that you want. 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.
