VLC can do capturing and should allow you to choose codecs and mute audio.
Yep. Rather than opening a file you can capture and save to file.
Ta, I managed to get this to work but it doesn't show me on the screen when it's recording. I need to see that my hands/face are in shot correctly enough to be read.
There's a box that you can tick that says "display locally". Try that.
Nope :(
That gives me a still shot from the moment I open the camera and only shows that 1 shot.
Same here :C
Just opening the webcam without streaming/recording works fine.
Ah bugger it. For now I have taken the file from webcamera.io and edited the sound down to 0 in Movie Maker. It still has the sound data in it, but just saving the file again with 'recommended settings' shaves off a few MB.
