4K Chat

Sorry to 'break in' to this discussion. Does anyone have any hands on experience as to what kind of hardware/software is needed to process and monitor 4k properly? Can it be done on a (high end) laptop?

Hi Stef.
Yes it can. I'm using my notebook for editting 4K footage. This notebook is 1.5 years old but can still handle everything properly.
GTX 570M with CUDA, 3GB graphics card
Quadcore i7-2670QM 2.2ghz
16GB RAM.

It's a BTO notebook. You can choose your own specifications and they build it for you in a few days.

Miz, if you kick the tripod or bump the camera and get jello it sucks. But that's not what I'm talking about. I think rolling shutter is overemphasized because I personally haven't had any issues with it. I've been using the EX1 and EX1R since it was released and not had issues. I've shot lots of eagles against lots of different backgrounds and done fine. Maybe I'm not as critical as you or maybe it's something else. I don't know. Anyway moving on, a small sensor, like in the Z100, isn't generally gonna look as good as a bigger one, but it does have some specific benefits. The two benefits I'm most interested in are deep focus, having as much of the action as possible in focus, and the reach. Put a larger sensor on the Z100 and there's no way you'd get 600 odd mm of reach. (The 4K 60p and 10 bit 4:2:2 are a nice bonus.) I'm getting this camera with specific shots in mind, mainly nature/wildlife stuff shot outside in decent light. For that it should be good. If not, back it goes.

Mark the Z100 uses the same Exmor R CMOS sensors as your EX1/R but doesn't have the same low light value as the EX1R due to how they used in the new camera.

Thanks Wout! Surprising, yet great, to read that your laptop manages to process the 4k footage. I would have imagined it needs very powerful videocards, internal memory etc. to display the footage properly. Did you run into problems at all?

I have a big question for you Sony 4k guys. Does a single frame capture have the same or nearly the same quality as a still making it possible to use a single frame and sell it as stock photo?

I have a still from my FDR-AX1 in the queue here. We'll see if it passes inspection.



From this video:

It totally depends on what kind of shot it is and in which lighting.

SO OD are you totally pleased with the AX-1 or have second thoughts on the Z-100?

I'm pleased with the AX1. If I were a functioning production company, I'd prefer the Z100 for the more robust codec. But for stock, which is all I do for the most part, I think the lesser model is sufficient.
