Capture everything on your screen with oCam. Download it free here.
If you want to record everything you see on your screen, you need a tool like oCam. oCam is a screen recorder that uses built-in video codecs (AVI, MP4, FLV, MOV, WMV, TS, VOB) and an audio codec (MP3) with real-time audio encoding.
You can also take screenshots in multiple formats (JPEG, GIF, PNG, BMP).
You can schedule recordings and choose what should happen when the capture finishes. Video output supports files larger than 4 GB.
You can record the entire screen or just a single window.
The program works on PCs running Windows XP, Vista, 7, and 8.
