Use Recordmydesktop for screen recording under Linux

In the near future, we are evaluating the possibility of providing video tutorials to users to demonstrate some of the tutorials that can be better expressed with video. When digging into this problem, we found a very rich tool that could be used for screen recording. The differences in the general nature of these programs are: Video quality, performance, compatibility. In this tutorial, we recommend a recordmydesktop that will make the desktop video easier.

Installing Recordmydesktop

The core of Recordmydesktop is a series of command tools, but Gnome KDE has a very useful graphical interface tool. In this tutorial, we use the Gnome version. Ubuntu users can use the following command to install:

sudo apt-get install Gtk-recordmydesktop

Or you may not be bothered to download it directly from the SourceForge website.

Working principle

The Gnome frontend will add an icon to your panel while the program is running, and you can start and end the recording at any time by marking it. When you start recording, Recordmydesktop will record all of your desktop (if only one part, below), after recording, you can save to the/home directory in OGG Theora format. Of course audio, sound can also be added to it, or just click on the box can be banned.

Set up your video

When you open gtk-recordmydesktop , you can see the following Setup screen:

Here are a few very important parameters, you can see a scroll bar never set the video quality. In most cases, higher quality means greater video size and slower encoding speed.

Another useful setting is to select a window. With this, you can choose which window to record, or choose a square shape to record in the thumbnail desktop.

Advanced Settings

Most advanced parameters, no need to control it. There are still a few items you might want to know, especially in the performance performance options. The default settings work well in most cases, but if you want higher quality, or if your PC is performing well and your video is fast, you'll find some useful settings here.

Processing output Video

As mentioned earlier, Recordmydesktop will save the video as Ogg format. Each video you record will be saved to your/home directory such as Out-1.ogg, Out-2.ogg, etc. If you want, you can choose a video editor to edit your video. Not all editors are supported in OGG format. But there are many tools under Linux that can convert your video into other formats.

Use the following command to convert your video to a more extensive AVI format:

MENCODER-OVC LAVC-OAC copy-lavcopts vcodec=mpeg4-o Nameofoutputfile.avi NAMEOFINPUTFILE.OGV

This will get a compressed MPEG4 format for the video.

If you want to convert to a different format and don't want any video loss, you may want to convert the video to another format so that there is no loss of quality while other editors are editing it. Also use commands that are very similar to the above:

MENCODER-OVC LAVC-OAC copy-lavcopts vcodec=ffv1-o Nameofoutputfile.avi NAMEOFINPUTFILE.OGV
