Disposable Video Camera
Moderator: Andreas Wideroe
let's make a movie... camera... cartridge... replacement.
Here's something I don't know enough to understand:
If we crammed all this junk into a S8 cart, what lens characteristics would be necessary to focus on the film gate so the lens would see what the film normally "sees"? (I assume the front optics of the lens would be essentially flush with the cart edge, replacing where the cute ribbon of film usually sits, or maybe somewhat recessed from there if optically necessary/possible.)

btw, apologies to T-Scan for hijacking what was a perfectly useful thread before. :oops:
So the S8 camera lens itself would focus the image onto the CCD exactly the same way it does on the emulsion. That makes sense...audadvnc wrote:The CCD or whatever sensor is used would be placed exactly where the emulsion side of the S8 film normally rests. Perhaps the sensor would need a backfocus adjustment screw to allow people to throw it completely out of whack.
If you started the video running, then started the camera running at xx fps, wouldn't the constatnt video simply reveal the shutter passing by xx times per second, with the desired frames in between? wouldn't it then be possible to write a filter that finds those black/blurred frames and chops them out, leaving only the desired frames?
this seems easier than trying to trigger frame-at-a-time capture with the claw or some such... but i am probably radically oversimplifying things. :oops:

Or just ignore the shutter, claw, motor and all and use the S8 camera frame as a holder for the video capture cartridge.
The two advantages of this are that:
1) you can use an existing lens and camera layout for shooting, and
2) chicks dig film makers more than video tourists. And you know what that can lead to ... :twisted:

1) unless and until there's a tiny, cheap CCD setup that does 24p (decently) you'd still have the motion characteristics of (yuck) video; i was hoping that the shutter-chopping could make it look and feel a bit more like film;
2) somehow we need to tell the cartridge-cam when to start recording, and i would hope a) we don't have to take the film door away so you could use the cams as built; b) we don't have to add any buttons; and c) the trigger could still be used to start the camera, except in this case it would start the cartridge camera instead of the camera motor.
3) sometimes if you lie down with chicks you get up with twins! 8O

Of course, if you just shoot video you won't have to worry about chicks & twins, 'cause you'd be <handling> everything yourself with the computer!
Wash. Post, again: "Osteopornosis: A degenerate disease.":evil:
So what's another button, switch or 3? My weird converted Auricon has a half dozen switches, buttons and whatnots on it, none of which operate the motor. I had to make a special cable with a remote switch to turn it on & off. It confused the heckoutta me when I first tried using it.
Seriously now, I'd recommend a flat cable connection from the world to the cartridge that would allow you to close the door, like the flexible circuits you find in disk drives. Some adapter box would need to fit on the camera near the door to allow video and power connections. The 24p CCD sensor has got to be out there somewhere, we just have to find it.

So did I, until I realised how long I have had my Canon Hi-8. Obviously built to the same standard as the Canon cine cameras.Angus wrote:I thought all video cameras were disposable?
LOL
For movies to go onto a web page and my low level telecine technique it is perfectly adequate. Mind you, I tend to keep most things until they drop, so i will never know if it will last as long as my first quarz8 cine camera
New web site and this is cine page http://www.picsntech.co.uk/cine.html
All I would like to add is that this camera should more resemble a fisher price pxl2000 more so then a 24p digital camera. The claw only needs to activate the inner camera to start/stop recording (if at all). Software should be required to remove frames w/partial shuter in them, unless of coarse we like the effect and prefer it! Fun and then function should be the order of the day. otherwise it's not worth it, we all know that! right?
without knowing exactly what a pxl2000 is, i think i can say i generally agree. i'd rather use a super-cheap ccd continuously (30fps/whatever) and see the shutter than use an expensive 24p CCD and bypass the camera altogether. at least i think i would. ;)chachi wrote:All I would like to add is that this camera should more resemble a fisher price pxl2000 more so then a 24p digital camera.

sounds like a glorified video tap in a box is what we're getting at, except that it's video tap ONLY! :roll:
