Ridley - The Movie!

[tel]

OK, I didn't say it was a great movie, or even a good one. In fact it's pretty crummy, but - see it here ....

tel,
Nicely done, the engine is beautiful and the video isn't that bad at all. As an aside, one thing I have noticed on many videos (not just yours), is that apparently due to camera shutter speed or something, there seems to be a stroboscopic effect. Can anyone comment on this with suggestions on how to minimize the effect.

Again, a very nice build !!!! Thanks for sharing it in the other thread, and now in "Ridley - The Movie"

Beautiful engine Tel.
Just how fast was it going?
A little suggestion...more video! More angles. ;D

Ah. Just saw your other post. 300 RPM. Very nice picture too. Thanks.
But more video!...and angles!

Thanks blokes.

Bill - yes, that is strobing something fierce - to the point of having 'wagon wheel' syndrome.

Zee, first I gotta get hold of a way of making 'em - that was with the vid function on my still camera - very limited

Hi Tel,
I have a Canon S2Is camera. It has 4 different options for movie taking. They are all related to speed and frames per second. Being as it's a picture camera with video capabilities when I shoot videos at the finest settings the files are huge and take forever to download to YouTube so I shoot at coarser settings. The videos are quite acceptable but they present that stroboscopic effect on moving parts. On my Holt video it stutters the operation of the rocker arms somewhat. Check to see if you have different settings available on your camera and if you do try taking a clip at each one and see what happens.

Yeah - a really good one - the machine and the video !

It could be interesting to see (and hear !!!!) it start from completely stopped and then starting up to running very slowly.

Nice work really ! Thm:

The stroboscopic "waggon wheel" effect you see is called aliasing. It is caused by the sum and difference effects of the frame rate and engine rotational speed. The closer in speed they are, the slower the engine will appear to move. Not a great deal you can do about it other than change the engine speed.
