I've got some 8mm film made years ago by an uncle. I've had it put on VHS tape.
How can I get it in a format where I can upload to youtube?

You need a capture device on your PC to grab the video footage and make it into a computer file.

Something like this:

Thanks very much indeed alchresearch.
Simple when you know how.
