I use Dxtory .D.

Point your phone camera through a telescope when recording so that it's extra high quality :o

Quote from Ashlander

My wife does Youtube and she uses Bandicam for PC recording. I can't remember if it was free or not though. I'll get her to come here and give you some advice tomorrow.

Yup I've used bandicam for quite a while now, and love it! I agree with what everyone's saying about the computer age though, there is only so much that software can do to help an outdated system. However, there is a free version of bandicam that you can download and try out to see if it's any good for you, it's exactly the same as the paid version, but with a huge watermark over the video saying www.bandicam.com or something, but it's useful to see if it works at least (also just checked and the free version has a 10-min time limit for recording, the paid is unlimited).

Bandicam can do added microphone and webcam, but every addition you add to a recording can slow things down (maybe = lag). I personally use my external mic through bandicam, and sync up a video recording from a camcorder in editing afterwards. It also does in-game full screen recording, or screen capture which you can set the crop for before starting. I know there are other good software's out there, but I got bandicam first, and have never felt the need to change!
