Working with Canon 7D

In what way are you thinking people are using Decimators with HDSLR's? Decimators don't do the HDMI to HD-SDI conversion, and while they will downconvert HD-SDI to composite video, the camera already does that.

my mistake, I thought it did the same thing my little Blackmagic box does. The HDSLR standard definition(NTSC/PAL)output is terrible no matter what company (Canon, Nikon, etc) makes them so I use the box to convert to both to both HD and SD. It still isn't 100% and I suspect the manufacturer intentionally downgrades the signal. Even converting from HDMI to SD SDI will give me a much clear, brighter and sharper image than the standard NTSC signal from the in-camera converter.

I've been using the Blackmagic since my early days with the Canons so I can't comment on the SD output from the camera. The Blackmagics are, sadly, not built to last and I've had one go down on me and I expect the other to go eventually. When I work with both of my cameras simultaneously I use the Nanoflash as the other HDMI converter--it's overkill but works solidly and reliably. Only works with the 7D and 1D though as it doesn't recognize composite SD which the 5D outputs while recording.

 

So Sydney--what monitor are you viewing SD-SDI on (that doesn't also display HD)?

None that I (Currently) own, I doubt any manufacturer makes such a monitor anymore, but I've run into quite a few older ones. I had a Marshall (Piece of shit) LCD monitor thjat only accepted SD SDI, that one crapped out on me around 2008 or so. A jib guy I know uses a color Sony CRT field monitor and the digital SD is the best image I could get from the HDSLR to his setup. On a side note, I am currently on my 3rd Blackmagic box in 4 years... If anyone knows of a semi-waterproof converter box that can handle high heat and massive, oppressive humidity, that would be rad

So I just bought a Flyer LE and the standard monitor only takes SDI. So whats the easiest way to fly a 7D? It seems like I need a convertor or a new monitor that takes hdmi. What is the easiest option that wont kill my bank account? I just want to get the 7D up and running and didn't realize it would be this difficult.

No Ben, the standard monitor on the Flyer accepts SD (aka standard def) video. The optional HD monitor accepts SDI, component and composite. Which one do you have? Does your sled have both a composite and separate HD-SDI BNC on the top stage or just the composite?

 

If your rig is SD only, you just use the supplied AV cable with the 7D and you are good to go.

The sled only has a power and video (SDI BNC) on the top of the sled. So I'm guess that the monitor is HD?

SDI is a signal type, BNC is a connector. SDI can be Standard Def or High Def (SD-SDI vs. HD-SDI). What you have is a BNC that carries a Composite signal (Standard Def, NTSC) You just need to use the A/V cable that comes with the camera and put an RCA-BNC adapter on the end. Just a few bucks from Radio Shack and you are good to go!

 

SDI is a digital signal, Composite is analog. They are completely incompatible with each other. They both often use BNC connectors, but you'll never get a digital signal through to an analog monitor (which you have).

 

The BNC cable doesn't care what signal goes through it, the source (camera) and the destination (monitor) care.

Thanks Brian, that was very helpful.

A BNC connector can be several things. It can be a composite (Single cable analog) signal or it's serial (digital) as in SDI. The digital signal can be SD and/or HD. Is there a label on your connector? It can also be a component signal, but component refers to the fact that the signal (Analog) is split up into miltiple ports. Since this requires three separate BNC connectors lined up side by side, that's the only one ruled out based on what you've written. As I said, hopefully your monitor's input is labeled one of those.

Brian and Sydney were more than generous with their explanations. Ben, I'm going to get a little stern on you with this--you spent thousands of dollars on a Flyer and you didn't know whether it came with an HD or SD monitor? Or even how to tell which one it was from the back panel connections? Or apparently the difference between SD and SDI? I can't recommend you to any specific resources to learn more about this sort of thing but the internet is a wealth of knowledge and it's not really appropriate to prune this information out of working pros when these answers can readily be found elsewhere. For instance, I went to the Tiffen site and downloaded the Flyer manual which clearly shows the different top stages and monitor models. If you don't already have the manual, you should do the same. It would have answered your last question.

 

Takes a lot for me to lose my patience with newbies but well, you got me with this one.

Charles, I thought the same thing and almost gave a similar response. I guess I'm in a good mood today :)

 

Ben, Charles is right. I can't imagine buying something this expensive without doing the research to know how it works with a camera. Your question could have been answered with quick internet searches. That said, fly safe and good luck!

 

I haven't seen Charles this frustrated since the last time Ron got too drunk and mistook him for an australian supermodel. At least there was plenty of Lisagav handy.
