MadameBerry Yeah, 'Action!' gave me by far the best results. The others I tried seemed to have bad frame rates and audio issues. Whereas 'Action!' seems to have less overhead, plus it's pretty cheap to buy a license.
The only slight negative is that I couldn't trim the video in it. However I used VLC for that.
Can anyone recommend good video editing software with VFX? I tried MS Movie Maker but it reprocesses the video which ends with poor quality results.
