Using Capture for Live view using a Nikon 7200 DSLR camera

[paull46289482]

I would like to use the "live" (Capture) view in Premier Pro when shooting a video using a Nikon 7200 DSLR camera. But it alsways reads Capture Device Offline. What do I need to do to use this feature?

Hi Paul,

You need to create a connection between the Camera and Premiere Pro. DV Camcorders used to operate over FireWire quite well for this task. Since these have gone the way of the dodo, you need to get the signal in some other way. I think you can still capture via SDI, but I have to check on that for you. So, you'd need to somehow adapt the HDMI port from the camera into a capture card or similar interface, and a way to feed the connection to your computer.

If someone has a better way, let's hear about it. If it were me, I'd record the video and then import it afterward. Live capture is always rather dicey.

Thanks,
Kevin

That is what I am doing now. I was just hoping to get a larger screen to view on as my videos are for jewelry, so the focus is very important on the small stones. Any other suggestions on how to acomplish this?

The capture option is designed for capturing from tape and not for live video.

You'd be better off capturing your footage through a streaming software and then editing in Premiere. (If needed.)

Thank you all for the responses, greatly appreciated!!!

Kevin is right. You have to go from HDMI out to SDI ( using an HDMI to SDI converter first ) and then have an SDI input on your computer ( separate card, usually in the PCI-express X 8 slot ).. and go from there..

You'd need a very fast computer and SSD or hard drive to 'capture' the stuff to the computer and a LOT of room on the drive...

It's complicated and you'd have to work out those complications ( like how to adjust the image with LUT or some CDL thing and stuff like that ...)

I use did similar thing using bmpcc but also have a nikon D800 ( with live view  ) and the easiest is to just record on card(s) and put that into computer. But if you have to do the live thing ( like growing file ) it is best to research a bit more.

Thanks for the input. I just wanted to have a bigger screen when doing videos on jewelry to make it easer to adjust the focus. I have HDMI ports on both the computer and the Nikon 7200 so I was hoping to be able to use the computer screen (monitor) to view live. Is this even possible?

Oh, I'd just buy a field monitor and be done with it. That's what most camera ops. do. Check out the YouTube channel by Potato Jet. He's the man when it comes to stuff like this.

This is what I use.. but I don't use to capture video.. I use it to go to video monitors ( SDI video monitors). It's not worth it for me to capture live for a couple reasons ...

Oh.

well, basically the hdmi on camera is an output and the hdmi on the computer is output. So that won't work. You can go right to your TV hdmi input from your camera.

live view ( on my nikon dslr at least ) is simply raising the mirror out of the way of the chip, so your lcd screen give you the image and the TTL option ( viewfinder via mirror ) is shut down.. the mirror is up and you can't see through the viewfinder ( Through The Lens ( TTL)) anymore.

This is true for stills and video ...on my Nikon.

When you use live view the chip is seeing the light from lens and the hdmi output also shows you what your camera is 'seeing' ( the chip ). So when you hook up camera to TV or external monitor from hdmi output of your camera, you will see ( on the added monitor via hdmi output of camera to TV or monitor hdmi INPUT ) what the chip is seeing.... that should be good for you re: focus.

It will NOT BE good re: color and levels etc... as you'll still need to use your WB, Lighting source colors, and histogram to determine if your shots are OK when you press 'record' to your cards.

For focus I wouldn't even bother with a field monitor ( many of which use SDI and HDMI but are NOT dependable re: color and levels.... 

In other words, without really getting into color 'calibration' ( like optical units you stick on monitor to adjust the color for your 'space' ( like rec 709 )) it's unlikely you'll be able to rely on most field monitors for color being correct. And they can be expensive ( field monitors ). Some are really small and some are very large, but it's a can of worms to get them to be correct regarding color. Your LCD screen won't be the same as the field monitor and it's just complicated and expensive. 

Here's pic of a Lilliput field monitor under a more professional video monitor. Notice how blue the little monitor is in foreground. It's the same exact SDI signal but the 'correct' color is the one on top ( a real pro monitor ).

FOR FOCUS ( which is what you want ) just use a stupid TV set .... it's cheap and will give you large image to help you focus. Then just use your histogram and WB and all that stuff to get the image you want that is right with color and so on...  kinda hard to explain, but start out with a TV and then as you progress you can get into more expensive and complicated stuff ( like field monitors and hero monitors ).
