Source Recorder Problem

I have been trying to make a Gmod Machinima but I can’t seem to get Source recorder to work! I followed several tutorials to the letter but all I end up with is a .mp4 file with only audio. I really need your help Facepunch as I have been trying to do this for over a week!

Try just recording as .tga files in a sequence, then loading the first file up in VirtualDub. That’s what I do.

Then again, I moved on from that method and moved to something that won’t kill my hard drive from huge video files.
