I know nothing about this area, but Mums just asked me to help her and her business partner put together a DVD demonstrating their healthcare treatment techniques. They are "leading edge" in their field and need visual before and after documentation to convince others, particularly the mainstream medical community, that their results are real. To be clear, this isn't "crystal magnets and stuff"; it's advanced physical therapy and neuro-physiological techniques invoking neuro-plasticity and the like.<p>Nothing too fancy required of the video, except that faces need to be blurred. Does anyone know of an open source / low or zero cost editor that can do that reliably?<p>Once, some years in the past, she spent some thousands on a professionally produced videotape, but was underwhelmed with the results and a bit overwhelmed at the price tag given the relative simplicity of her editing needs (although I can see face blurring as a multi-hour "target shoot" kind of exercise, for the editor). Thus, this time her "computer literate" son has been drafted.<p>EDIT: She works a lot with disadvantaged children. Good work, but there's not tons of money in it. So, she's not just being cheap. And as I'm between jobs, I'm avoiding expenses, myself.
