I’m going to be teaching a sketching course next semester, and I need to be able to use a camera, capture what I’m drawing, and have it stream directly to the computer so it can be projected. Think of it like an overhead projector, just with a video camera+computer instead. Does anyone know what sort of camera can broadcast what it’s recording directly to a computer? I’ve tried Googling high and low…
It’s not a web-stream I’m looking for. I’ll actually be in a classroom, and instead of having the students crowd around me, I’d like to be able to just project directly from what I’m drawing. Our school has the computers hooked up to the projector in every room, so I just need the camera to be able to stream to the computer. I guess I could just use a webcam. I was hoping for some better quality (maybe investing in a flip or something), but I guess there are some good quality webcams out there.
I think the process is called ‘tethered shooting’ or ‘tethered video’. Most cameras can do it, but i think its a software thing. This guy has video up on youtube doing it Canon 7D tether test - YouTube Horrible video but shows its possible.
Wait, classroom has a digital projector? All digital projectors that I am aware of have at least a RCA (round yellow plug) input. All video camera and even digital point and shoots have a video out plug. It usually looks like a headphone jack, but you stick a mini plug in with a yellow rca on the other end which plugs into the projector. You shouldn’t even need the computer. The camera will pipe what it would show on the screen out to the projector. You might need a power source for the camera.
MPdesigner: Yeah we already have a nice iMac set up, but I want to teach traditional sketching techniques in addition to digital.
bennybtl: Yea it’s ceiling mounted, and as I’m not at school right now I’m not sure how high the ceiling is/if the cable would reach. Also, isn’t that capability only for playback (meaning after you recorded, you can play it on a TV) and not for live streaming?
egicas: That would do the trick but I don’t have a DSLR with video capabilities. I just sent out an email asking if any of the students would mind bringing one to class every week, haha. Hopefully that works.
If not then I’ll have to buy a webcam. Lame. Thanks for your help everyone!
That would be a pain if it is ceiling mounted. To the best of my knowledge, cameras will output the live display / viewfinder image to the external video, not just playback. I’ve used this feature many times.
All cameras are capable of this. Think along the lines of your local electronics store. You walk into any A/V section and they have the cameras all turned on and many of them are attached to a TV to attract your attention.
Maybe go into your local Best Buy, or whatever, and ask them how they do that?
