I used the original trailer for Night of the Living Dead (1968) as my model and mashed up from there:
Overall, I was happy with the final clip, seeing it, obviously, as an exercise. But I'll share it with the students (and with all of you). I could do a lot more, and I'm not happy with my voice over (I plan to hire my youngest son, who has done some acting, to do voice overs in future videos), but it did help me get a sense of mix and mash.
My goal for the semester is to create quality videos. I realize the learning curve that comes from this new medium, and I plan to upgrade from semester to semester, but I hope to incorporate a full range of audio, video, image, and text so that they can be as helpful as possible to the students.
If you're interested, here's the original trailer from Night of the Living Dead:
