Advice on Remote Triggering of VIDEO with Canon DSLR's ?

We need to be able to remotely trigger the VIDEO mode when using the various Canon DSLR's. We would like to avoid the cost of buying the WiFi attachments since we use multiple 1D/5D/7D cameras. Five of them on a recent shoot.

We need to be able to trigger them from at least 10 meters/30 ft distance, ie. further away then the typical Canon hardwired or IR remote.

Anyone have any idea why the IR Receiver is on the FRONT of these high end DSLR's? I can understand it if they were consumer cameras, but how many pro's want to take self portraits with their 1D mkIV's !?

Re: Advice on Remote Triggering of VIDEO with Canon DSLR's ?

one way would be building mechanical button pushers from servos, and trigger them remotely/wired/RF (similar to the camera release of the gigapan head).

another solution would be buying a bunch of cheap IR remotes off ebay (they need the 2 sec canon option to trigger the video, something like the $2 KM Jianisi RC-4), and wire/solder the button in the remote to any sort of RF remote (i.e. cactus or anything), and gaffertape the IR to the camera/rig.

not pretty, but it works/should work.

canon is supposedly working to release the RC-6 this summer, but right now I don't know what's the difference to the RC-1 (besides that it'll cost $100).

as for why the IR sensor is in the front, I have no idea why there isn't a second sensor on the back (i.e. combined with the cheek/eye sensor). but you can rig something from foil/white paper to bounce the IR signal from the back to the front sensor. i often found that i.e. my lens shades reflect the signal quite nicely.

alternatively, I've seen arduino projects that produce the exact IR command sequence.

another alternative would be if promotesystems.com would include the start/stop video function into their promote.

Re: Advice on Remote Triggering of VIDEO with Canon DSLR's ?

THANKS ... There have been times when we've rigged up one of our extra focus/zoom/iris motors to physically hit the video run button on the cameras, very clutzy!

I wonder if this will work?

no, this can't work... whatever is using the N3 connector can't trigger the video, unless canon changes the firmware fundamentally. all this does is take a picture...

So splicing in more cable to one of these Canon Remote's won't trigger Video Roll in Live View?

no, the 3 pins of the N3 are literally just half-press and full-press and ground... there is no other signal on the N3... unless canon changes the firmware to use full-press to start/stop video.

canon: if the user is in live view (video), who in their right set of mind want to take a photo and interrupt the video? seriously! why not simply allow video recording on the normal camera release?

you know you get those on ebay for 10% of the canon equipment?

OK ... thanks ... so far it's the klutzy Switrionix Flex-RC1

really? $150 for a IR remote? do you not have an electrician/grip on your team that can take a $1 remote apart and give it some longer wires and a new button?

it seems that film business has a huge profit margin so you don't have to worry buying single task equipment for $$$.

The problem is that you have to have live view on to start video, but the camera doesn't "know" that you want to do video -- you could just be using LV to fine tune focus for a still photo. I agree though, it would be nice if the camera could be put into a mode where the shutter button starts / stops video recording. It would also be nice if there was a way to start video without first having to enable LV -- since LV times out in 30 seconds (on the 5D Mk II anyway). Then the inexpensive RS-80N3 could be used effectively for video.

Re: $150 IR remote ?

I don't believe that one will work with the 1/5/7D's ... I ordered this one:

Canon is using the same IR protocol on all cameras, the "fire now" and "wait 2s" mode. The "wait 2s" code is what is triggering the start/stop video... unfortunately, there is no reasonable way to enter live view.

Here is some extensive documentation on IR signal (and the 3-pin canon connectors, either N3 or 2.5mm plug):

alternatively, and I had not tried this gadget, so I am not sure how good it exactly is, you can use the WFT-E4:

http://www.bhphotovideo.com/c/product/664918-REG/Canon_4263B001_WFT_E4_IIA_Wireless_File.html

supposedly, you can control it from your iphone/ipad/laptop via wifi in your browser. 7D needs a different one: WFT-E5A

Use DSLR Remote Pro from Breeze System

http://www.breezesys.com/DSLRRemotePro/

The newest version v 1.9 has video control and download to a PC via USB cable. It also has a multi camera version that will save to the CF card.

I highly recomend this software for tethered shooting-fast, big screen, and easy scrolling.

-Scott

Re: Use DSLR Remote Pro from Breeze System

Weird ... for Windows. I don't know any shooters that use Windows!?

Re: Advice on Remote Triggering of VIDEO with Canon DSLR's ?

buy the cheapest, used rc transmiter and receiver you can buy. Look up jomar shutter releases on line and you will be able to trigger the camera from a mile away. I use the jomar devices on my RC helicopter to triger my canon DSLRs. Works like a champ, no servos necessary.

If so, can you offer some detail about which of their product(s) you're using? And can it really trigger video remotely on a 5D? I.e., enter live view, then start & stop video recording.

as alan said, what exactly do you trigger with your remote... please elaborate, i am curious.

Re: Advice on Remote Triggering of VIDEO with Canon DSLR's ?

yes, that is the site. http://www.emsjomar.com/SearchResult.aspx?CategoryID=6

see 2nd item from the bottom. In photos you can see how the standard servo wire is connected to the jomar device. This particular device allows for a double electric connetion. This causes the camera to first focus, then releases the shutter. I included a photo of the box that contained the remote shutter release, I just cut the end off and I suppose if I had done a little more research, I could have saved a dollar or two by going to radio shack. I assume you are familiar with the remote shutter release stuff, but you might not be familiar with the servo wire stuff. If you purchase the jomar device as I suggest you should be able to get help at your local hobby shop with the other items. As i said, you just need a dirt cheap receiver and transmitter. Used will be fine. Lots of RC guys have old crap lying around that they should be willing to part with for cheap. I've got a couple of old radios and receivers that are 25 years old that would do the job. Ask around at local clubs if you are on a budget and you'll find something.

I am not 100% sure whether it will trigger the 5D video as I don't own one. If a standard remote shutter cable will do it, this will too. I suggest you take your 5D to your local camera shop if you don't have a remote shutter release and ask to try one out. I suspect it will work.

well, thank you very much.

If you would have spend a little more time reading this thread, you would have learned that with the current firmware (1.0.6 - 2.0.7), the regular remote still triggers only a photo, it doesn't NOT start/stop video, does not start live view. all it does is focus and fire.

triggering that port is insanely trivial, and your remote solution is interesting for taking pictures, but that's all to it. it doesn't help with video, which is the whole subject of this thread.

Re: Advice on Remote Triggering of VIDEO with Canon DSLR's ?

oops. Sorry. I assumed, incorrectly, that the same port would allow video start stop. Why they wouldn't program that in the capabilities of that port is beyond me. Guess I should stick to answering questions about the camera I have.
