learning to youtube

So I fought with blender for the last 3 or 4 days to get this video rendered and cut 50% out. I made a fatal mistake and recorded the whole thing in 50fps and had to find a way to recode it to 25fps - sad that I will have to use Magic Lantern just for the option to record 1280x720 at 25fps, but I will try it. This is unscripted and you can clearly hear me thinking :D There is a jump mark to get to the part where it's moving. Sounds like an old film projector, so I still hope I can get something 3D out of it.

nice. Snap-together. Good idea.

Not sure if I said it before, but that rack/pinion system is pretty groovy.

And it looks like it's moving much more smoothly/reliably than before. Awesome.

(Unrelated: I kinda dig the aliasing-effect of it appearing to move much more slowly and somewhat warped in the video. Dang, that thing must be moving *fast!*)

Are you sure? yes | no

I downloaded the video, then opened the sound in Audacity, zoomed in where it is moving and selected one second:

Then counting the spikes shows that it is moving with 28 Hz. Probably there is a spike at each end, but then you can update the LEDs in both directions, so 28 fps is possible, if the weight of the LEDs doesn't slow it down too much. Might flicker a bit (flicker free with 50 Hz with a stronger motor), but good enough for a first test.
