Nat thanks for comments & link on Virtual Dub’s Deshaker Plug-in.
Yes I have used it before in Virtual Dub, often tricky to setup if you don’t use the default settings.
I still don’t know why people occasionally use video cameras to film tv screens, you are always going to get a poor results in picture and sound, especially picture due to tv line frames.
Tv & film or video cameras don’t work together. Just learn to use PVR most tv ‘s have them now days, or if your at a convention / exhibition / stadium where there are tv screens of products & services, maybe ask if they have the videos on their website to download.
