i am wondering if i can capture video directly from a Canon 5d mkiii into Premiere 6 to record interviews?
IS this possible via USB or HDMi?
Not with USB, but if you have an HDMI input device (Matrox or Black Magic cards, etc.) you can capture something from those.
The big problem is in what comes out of the HDMI ports on Canon DSLRs - you certainly can't record on the camera at the same time as that shunts the HDMI port into SD mode, but even in standby you get interlaced 1080 footage, and there are the status overlays as you see on the LCD screen. Canon currently only allows full-spec feeds from their "cinema" range of cameras, they intend to allow an uncompressed 4:2:2 1080 feed from the 5DmkIII in a firmware update but it's not coming out until April 2013. The Magic Lantern alpha build says it removes the overlays but you don't get 1920x1080 as they just mask out the menu regions. You also have to furtle about to keep the mirror up for more than 30 minutes and the sensor cool.
All in all, possible - yes. Useful - not so much. If you need single takes over the 4GB limit, it's a lot simpler to run with a conventional video camera. If you want to stick with DSLRs, I suggest recording to card, and running a B-cam out of sync with the A-cam so you can bounce across in the edit when each camera hits the 4GB limit. You might lose a tiny bit of latitude in grade with card-based footage at 4:2:0 over uncompressed footage from a cinema camera's output, but it's full-res and reliable.
The April upgrade claims to fix this issue. If you have to do it before then and can rent a camera then you might want to. Not all of us can afford to take Jim's "advice" when you consider the cost of lense changes to get one seldom used feature. (If in fact it's seldomused). I am beginning to wonder if Panasonic is paying trolls to post off topic thoughts like this, since I see them pop off like this on a variety of boards.
i checked out all the panasonic junk, only their video camera produce decent video, the DSLR video quality and colors are absolutely horrible, washed out like old 80s TV broadcast cameras, yeh the GH3 looks ok in natural light but forget it in the dark or even grey days, show me one decent video shot with the GH3 by a end user and not a professional camera person with 20 grand of extra gear and i will run back to the camera store here to see what i did wrong when i tried that camera.
This thread is about capturing from a DSLR with Premiere Pro - let's not devolve into a fight about which brands are better, as nobody will ever agree on that.
Without knowing how the footage is being used it's impossible to say which option is better - getting a continuous take with a video camera, or getting a specific DSLR-style look to the footage in 4GB chunks. If you record sound externally then it's trivial to hide any gaps with noddies, even if you only have one camera.
Dave's right. I was just being something of a 'fanboy' rather than posting a serious response. (Hence the wink.)
But if you're serious about seeing the superior quality of the GH3, I'd be happy to take this to the Lounge.
