FreeCAD Sizzle Reeler
See Exploded Part Animations Sizzle Reel section.
Idea is to scour YouTube for excellent videos on FreeCAD, but since many videos suck, it is useful to use them as footage for editing. Typically, empty space should be edited out, relevant commentary added, and video speeded up. For example, there is no point to watch a 10 minute video when a 1 minute tight edit could provide more information and waste less peoples' time.
Given that FreeCAD is progressing steadily, FreeCAD is beginning to proide a lot of useful footage. The point is to upgrade FreeCAD capacity so poeople learn it more effectively, to produce high quality design + effects rather than mediocre results. Mediocrity comes from a high learning curve, so improvement is made when users learn faster.
