Our format is similar to Toastmasters. There will be two video presenters, each with a length of 5-7 minutes. The first video will be instructional, and the second will be a project. After each take, the group will provide feedback, and the speaker can then do a retake, incorporating the feedback.
We will be continuously learning and this format is likely to evolve.
Gordon's Windows suggestions for video editors is Serif MoviePlus X6 for greenscreening, and Camtasia Studio 8 for editing and final encoding.
