View Full Version : My design for a DSLR - video cam hybrid

This thread (http://www.dvxuser.com/V6/showthread.php?t=183145) about DSLR form factor vs. a video camera got me thinking. I agree that a DSLR kinda sucks for serious video work. But then again in some situations it can be an advantage.

So if there was a way to keep the DSLR the way it is and just dock it to a "video camera adapter" you could have the best of both worlds. You'd use this VCA when you need the extra input/outputs or a shoulder mount. Then when you need a crash cam, POV cam, stealth cam, or you just want to shoot stills, you can un-dock the DSLR and use it as is. The bottom of the DSLR would have to be designed with a special base that can connect mechanically and electrically to the video camera adapter (sort of like the way they have optional grips for Wi-Fi or extra batteries).

The VCA would have a battery mount in the back for a large brick battery to counterbalance the camera and to power on-board lights. Also in the back would be things like XLR, monitor out, TC, RF mic receiver, heated cup holder, etc. We need as much weight back there as possible to counterbalance the camera! A top handle would be centered over the CG of the rig and an adjustable ENG viewfinder would be above and to the left of the DSLR. A rosette on the right side of the VCA would allow you to mount a zoom demand grip with a zoom rocker (for video lenses that come out). Then below where the DSLR docks to the VCA, you'd have some knobs and switches for commonly used functions, like on a broadcast camera.

I guess this is sort of like RED's brain concept. Except here, the DSLR is the brain and a cheap one at that. You can upgrade the brain by just swapping it out with a new camera. The big advantage here is this brain is already a dedicated still camera.

A dedicated video camera would be more elegant and robust than this thing, but you wouldn't be able to turn it into a small and light still camera (with video) if you wanted to. Wouldn't something like this VCA be handy if it was inexpensive? What you do guys think? Am I crazy?

I did a quick sketch of what this TIMCAM® would look like:

I was inspired by this Ikegami box camera:

Reminds me of a laptop docking station. I've been working off one of those for a while and frankly I think it's great. The docking station has all the ports and the real keyboard and the huge monitor and everything, AC power, additional drive bays, a PCI-E slot, card readers, all that stuff... and then when I want to go somewhere I just pop the laptop off and go. Your idea looks pretty similar to that concept, and while I don't know how this would work out for cameras, it sure does work pretty well for laptops...

Can't seem to be able to find the price anywhere. I doubt this this is going to be cheap. :-)

That is cool. But the only compact camera I know of that shoots 24p and is able to fit this rig, is this one:

OK, I'll bite, why won't the 7D fit in that rig? The demo clearly shows a 5D2 in there. What's the difference with the 7D?

BTW, found a press release in german that quotes the MSRP as 2380 Euros.

Badass! But 2380 Euros :(
I could buy 2 GH1s

I'm confused, where does the fancy viewfinder connect? HDMI out? Does the 5Dii give full HDMI output?

No, the 5DM2's (and 7D's) HDMI puts out something like 480p when the cam is in video record mode.

But at least that's 480 more p's worth of video than the GH1 puts out when it's in record mode. :)

I suspect the viewfinder on that Frankencam is only standard def res so driving it from a 480p source should work out kinda OK anyway.

Can't tell if for that price it comes with the Sony EVF , which are expensive alone.

Looks like they are using the old school composite output. The kit seems to include a distribution amplifier with 2 extra outputs to feed other monitors.

so awesome. best/most practical DSLR rig I've seen.

Ah, composite out. Ok, that explains a lot. Probably good for framing, but not so great for focusing then.

This is what I've always wanted...

You could honestly make all this yourself for hardly 300 dollars and a few days work...

2 things it lacks, but this is fromm a video journs pov. some sort of xlr adapter and a shoe mount on top. this could be a killer setup with a couple more additions.

Maybe... maybe not. Broadcast EVFs usually have a peaking control built-in.

Proper peaking is usually much more effective for judging focus than throwing more pixels at the viewfinder.

would a cheaper SD view finder, like say one from a canon XL1 work for focusing?

I want to adapt a Sony Betcam viewfinder to my Canon 7D.
These guys have apparently done it (as have some others...)
Does anyone out there have instructions on the mod....
Canon hdmi out to Viewfinder video in.... need pin diagrams for sony 20 pin connector...
Are there video breakout boxes on the market that might do this?

If you want a video camera, buy a VIDEO camera! I find it funny that the original idea of a small form-factor, DSLR that shoots great video is now becoming a bigger rig than just buying a video camera. Give it another 6 months and I'm sure you'll have your wish!

I am interested in collaborating online with anyone who wants to adapt a decen video viewfinder to the Canon 7D for doc work.... focus and rolling shutter being the two big issues with this camera.
I have 2 sony Betacam viewfinders... and early 4:3 from a BVP-7 and one from a DXC- D30 WS.... ideas on how to make them work, connectors, cables, breakout boxes, 12V power supplies....?


MAtthew,
brilliant work on your The Terminal film. good luck.
