You could say that there are 2 types of screen capturers, those that make a graphic capture of the screen, and those that record a video of everything that is happening at that moment on the computer screen, and this second case is the objective from ACA Screen Recorder.
Well, ACA Screen Recorder allows you to record in an AVI video everything that happens in a partial or total portion of the screen, thus registering everything in that AVI video and therefore being an ideal tool to generate tutorials. In addition, if the user has a microphone, it will also capture all the sound that is generated around the computer while recording.
Allows you to toggle the recording of the entire screen to a specific rectangle on it, and vice versa.
You can free download ACA Screen Recorder 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
