It's an excellent choice for those that have to provide technical support or developer who have to design tutorials to explain how to use their programs. The range of output files is admittedly limited - CamStudio will only output in AVI format but you can also convert movies to Flash (SWF). You can also choose the codecs used to encode your screen capture shots and set the frame rate you need to capture at.

For whatever reason you wish to produce a video for, Camtasia Studio makes it easy to impress your audience. It's a powerful and intuitive editing suite that's subscription free. With impressive little add-ons such as a green screen to throw yourself into the action on screen, it's a very useful tool, packed with great features, for amateurs and advanced users alike.
Camstudio falls into this latter category. If Stephen Spielberg were to take screenshots instead of make films then he'd probably use something along the lines of this app. Camstudio is an excellent and fully comprehensive screenshot solution for anyone that needs to go beyond simple illustration and really needs to show the end user exactly how to use an application on program.
Comodo blocked "CamStudio_Setup_v2.7.2_r326_(build_19Oct2013).exe" from installing, stating that it had a "Application.Win32.InstallCore.BWAN@1" infection. Nick Smith suggested disabling Comodo. Later, "PC Utilities Pro – PC Optimizer Pro" was reportedly being installed and being run without people's permission. Systems were infected with the following: "PUP.Optional.Delta.A", "PUP.Optional.Spigot.A", "PUP.Optional.InstallCore.A", "Rogue.Multiple", "PUP.Optional.CrossRider.A".[citation needed]
Ordinary screen captures are performed in much the same way as in most screen capture applications. Simply drag the mouse over the area you want to capture or tap in the coordinates. You can of course add text and for more complicated motion captures, a useful auto-tracking feature follows the movement of the mouse without you having to do a thing.
Why would a recording software have its default setting to not record the audio??!?!?!?!?? This has got to be one of the worst software design decisions I have ever had the misfortune to come across. I downloaded this software to record a family member's singing stream and it was not until I went to watch it later that I discovered it did not record the audio. This is a moment I will never be able to recover. Just because you give something away for free does not make it acceptable to make a crappy product. P.S. SourceForge, why do you not warn your users that this recording software has a no audio default setting?
