Timing Site Glass Cap or mirror thingyamajiggywatchyamacallit..... question

My Sony Digital 8 has a button called "programs". This lets me select for things like portait, or sports, or sunlight with hard shadows, etc. All it shows me are icons for each mode. I am assuming this would be the equivelent to a still cameras "ISO" and "A" settings. (however limited) This one also has a button called "exposure". This one acts like it conrols shutter speed.
I don't have a timing light here at the house to experiment with, but if I did, I would try to adjust for very bright sunlight, and the fastest shutter speed that will show up in the viewfinder when looking at the timing light flash. Probably even adjusting shutter speed while viewing the flashes. I'm thinking shutter speed is out of time with the flashes. If your camera allows you enough control, you might even be able to get to a point where it looks like a still picture when the shutter speed is timed with the light.
Now I wish I had a timing light here. I'd like to try it.

I just watched the video a couple more times. It doesn't really look like frames are being dropped. It looks more like the shutter speed is different than the strobe speed. There doesn't seem to be any glitching between frames. The timing light strobe is taking place between shutter openings. You need to change shutter speed, or change rpm, or maybe a little of both to pick up more strobe flashes when the shutter is open.
I don't know whether or not this can be accomplished with your camera. My Sony digital 8 has been a great little camera considering it is a consumer level camcorder. The adjustments are limited to presets. My XL1s allows me so much more control that I get spoiled. Problem is that it's just too big to take on the rides at Disneyland.

Today I started out to make a video useing the beavers thingyamajiggywatchamacallit, but to my dismay, it didn't come with a paint maker and I could't find anything here at the house that was suitable. All our fingernail polish is too dark (I guess we're into "goth" now?) and I tried to use type writter white out, but that lasted all of 3 revolutions to completely clean it off. So, what I ended up with was playing with the camera settings to time the shutter speed to the strobe light. First is the SONY digital 8. It uses icons to allow me to select presets. The one that came closest was the icon of a guy swinging a golf club? I suppose that one is for recording sports events.
Then I used the Canon XL1s. This one allows me to select shutter speeds from 1/8sec to 1/4000sec (I think) in 1/10sec increments. 1/30sec seemed to work best while idleing about 1200rpm. And I'm sure this will change with increased engine speed. I didn't try it because I was useing two hands as it was. Something I learned about this camera, the kit lens that came with it has served my purpose well, but I've never had to focus this close up before and this lens just don't want to get that close. So what you see is as close as I could get. I don't know what I'm trying to do, other than show my theory why Dan thought his video was dropping frames, which is a shutter speed issue.
Maybe I can get together with somebody "someday" and we can make an actual video tutorial on how to check the timing.
I think it would be tremendously beneficial to eventually have a "tech" section on this site with well planned out video "how-to's" for just about everything a guy would need to do on his wing. Wouldn't that be cool! :builder:

There's nothing wrong with using black nail polish, should see it fine..
