Oh dear ... time ...
Thanks Jonathon for the input.
Video well handled is good. but guys, be careful what camera you use. The common webcams give jerky movement!! That means (and check me if I'm wrong) it is NOT giving you the 25 or 30 fps!
To make up for poor sensitivity they (usually?) integrate over perhaps 1/6 second and replace the missing frames with copies of the last frame. Just like the integrating systems people are using for deep space video. The Meade DSI/LPI series are presumable of this type. For timing with this sort of camer you MUST know ...
The half frame issue niggles me. You can never KNOW something happened AT frame A OR AT frame B so I feel uncomfortabe ...
But then, the accuracy of the combined many observations is really what matters.
