This has great potential but I have never got it to work completely. It wouldn't even start up in the days of Vista, no matter what I did. On Windows 7 64-bit it's usable but with several elements not working.

For example I can only play video clips that are encoded as 24-bit with the HuffyUV codec. Anything else is a black screen and this is despite me using numerous other pieces of video software for capture and editing successfully with various codecs. There are many cries for help online regarding this exact problem but apparently it's never resolved with updates. Window capture doesn't work on my system either. It simply shows the OBS Studio window all the time.

Other than that, it IS possible to mix and record a good video (various codecs do work for recording), incorporating stills, video, audio and web pages and also stream live successfully to YouTube or Facebook.
