Requesting volunteers for an experiment

I'd like to do a short experiment regarding human memory. I'm looking for a handful of people who will be willing to watch a short video of some event I have yet to choose (nothing disturbing) and then answer a question or two about it whilst I record both the question and the answer. I'd then like to get back in touch about a month later to requestion you, the second interview will also be recorded.

1. You'll need to make yourself available via an Internet video chat for 5 to 10 minutes on two occasions, approximately one month apart.
2. You'll be free to change your mind at any point and no longer participate, in which case any footage of you I have will be deleted and not used.
3. You'll be shown the production before it is released and have the right to have your contribution removed.
4. To prevent a copyright claim on the final video, if you agree to your footage being used in the final video after previewing it then you waive the right to request your footage to be unused or for the final production to be removed.
5. Your face will be visible in the video.

Thanks!
