T2i Cooling down a T2I while recording video

Hi guys

thinking about a way to help the T2i to cool down while recording.
What about using a Peltier cell ? Does anyone has some thought about it ? Maybe together with a solid piece of aluminum to be attached to the bottom of the cam. Using some external battery (5, 7 or 12V). Since we don't need to freeze probably we could dimension it to be cold enough to help cooling to lower part of the camera body.
Anyone had some thought about it or suggestions ?

There are lots of zero moisture ice/gel packs out there you can gaff onto the camera- simple and cheap. Also something as simple as an umbrella on a stand over the camera can make all the difference.

When I do interviews the problem is more the 4GB file size .... :( but haven't been testing much yet.

If you are filming interviews with your camera IMO you have bought the wrong tool. I would suggest looking into the Panasonic GH1 which is another dslr ( as you may know) which allows you to record until the memory card is full and does not have overheating problems.


The T2i is an excellent camera but for long interviews IMO it is not the correct tool.

Assuming you can afford multiple cameras or have the T2i solely for interviewing.

B-roll and an external audio recorder pave over the most glaring issue, although it's still disruptive; but if you're running with a single cam and doing a lot of non-interview shots, is a little disruption of the interviewing side of things bearable for improved shots in most of the other footage?

I like the idea of a cooling pack and external battery. Regarding the interview application - ever since first using P2 media for interviews, I couldn't imagine recording any interview non-stop. I start and stop on each question, giving me a file system of separate sound bytes for every question that makes the editing process so much quicker. I think the 7D / T2i is the perfect interview tool.

Get a GH1. There is soon to be a hack to get TRUE 1080p..not 1080i

lol, why not just get one of those bloggie hand held recorders while your at it? Or maybe a VHS hand held camcorder!

LOL, suggesting dated technology with potential "hacks" is not the answer.

I agree a coolpack might help, but also just turn off camera in between takes for sure. If your rolling for a long long time, then maybe get an audio recorder to capture your audio, and turn the camera on and off giving a minute to cool here and there. Then just cut to B roll during some of those times.

Kinda crappy, but for just straight long interviews i might pick up an old HV20 or something
 
i purchased a 2nd grip for my t2i, exactly for that purpose.
i need to dismantle it to see where i can fit the peltier element, the cooling system and fan. With heat pipes heasink from computer, i think it should be possible to cool down the camera very easily.
Not too much since it will cause humidity to fix as condensation (but i am not afraid too much of that since the important parts are the hotter anyway).
probably the best would be to fix the peltier in the battery compartment of the grip, and push cold hair into the battery compartment of the cam.
At the same time it should be possible to pull air from the grip, sucking any hot air from the camera and cooling the peltier on the way back.
problem is peltier element sucks a lot of current (many amps) so big batterie will be mandatory. (but at least you got energy for camera and light too)
O n the other way , it should be more easy on the 7D, because you can cool any part of the metal body.
 
I had mine overheat a couple times, once after using it outdoors on a sunny day for 25 min at around 75 degrees, and another time after 45 min, similar conditions.
A week ago I lowered the LCD brightness by one notch (one less than midway) and since then, knock on wood, my little guy isn't burning up. Yesterday I was shooting stills and video in warm weather for 2,5 hours (on one battery!) in warm weather, and it was smooth sailing.
Try what I did and maybe staying out of direct sunlight and see if that helps.
