But...why capture bit-mapped *video* at all? I would assume that
users interested in learning how to use blender would actually have
blender available to play with. Why not *record the actions of the
user straight off* and skip the whole mess of video encoding/
decoding, incompatible codecs, etc? Could the blender timeline/
animation/ and sound systems help here somehow?
What about the idea of building a "filmstrip" that records the actual
user's actions--- not images of actions, but the *actual actions*
themselves? Learners could then interrupt, and rewind the "action
stack" (much like an undo stack...) to see what happened, or how to
do it themselves. I imagine that this would also have the added bonus
of paving the way to "filmstrips" in the game engine--- where users
could save a "movie" of their game play. Also, (being imaginative),
such an action recording could evolve into a history list--- much the
way that users can scrub through their history of changes in
Photoshop/Illustrator... Oh, and (being more imaginative) don't
forget that this might be handy for UI testing too.
Such a list would give valuable feedback to blender novices (and more
experienced users alike). (Huh? What did i just do?).
Presumably, this method would make training filmstrip download sizes
much much smaller--- and that's a win for everyone i think.
Of course, it would be up to the individual watching the filmstrip to
satisfy the blender dependencies for their platforms: yafray, python
scripts, etc... (packed .blend files might be handy here...) :D
just an "i'm in waay over my head" thought.
have a nice day.yad
