Which will work better?

I'm shooting some interviews on green screen, these interviews are for the kickoff to HBO's Game of Thrones - they will be fed to a Samari recorder (so we can have 4:2:2) via SDI to an editor who will composite the background and upload to their site.
It will be cowboy framing.

So my question; should I use my AF100 (lots of lenses) or my AC160a? Is there any discernable quality difference?
 
I guess the 160a has deeper depth of field so could be a good choice but I think the AF100 has a little more Dynamc Range and could make the subject look a little better?....

Its splitting hairs really, I'm not familiar with the 160a but if it has the same feature set as the AF100, for the task you have, I don't think either camera is going to cause you any problems, visually indistinguishable in a keying scenario but I guess at a comparable depth of field the 160a can have a lower iso/gain setting compared to the AF100 but this s a scenario with lighting so, meh?....
 
Hey Shooter,
that is a great suggestion except I am walking into an existing green screen set up and they are supplying the Samari.
I guess I could just set my smaller green screen and shoot something onto the SD cards and see if there is any difference in the image?
If test shows any interesting results I'll post some images.

I am doing exactly the same thing next week..walking into a green screen setup studio...but I only need to customise their autocue set up.

I feel its prudent to do a test at the facility before the shoot day... for my own peace of mind. :grin:

It would be the "Prudent" thing to do but I have no prior access. Don't think you're the first person to poke fun at my company name.
It's funnier than you know because other than work I'm not very Prudent at anything else.:dankk2:
 
Hey Barry,

thanks for jumping in, what would be your camera preference, AF100 or AC160a? any advantages to one or the other?
 
Which camera has a better image in your opinion? I haven't used the AC160a before but I would rather use the camera that has the sharper image. I've shot green screen before with the AF-100 and it worked fine in AVCHD so if your using the uncompressed 4:2:2 you should be good to go.

Which camera do feel more comfortable with? This always helps if problems come up. Defiantly bring both and maybe your client will pick one for you.

The only difference I've noticed when shooting with both cameras and comparing footage is: the blacks in the AF100 footage are darker, more contrasty. Not sure if this is a manifestaion of the sensor? Both scene files were identical.
As far as being comfortable - the only thing that's easier is being able to reframe with the 160a using the zoom lens.
(would love to purchase the Lumix 12-35 but not in my budget right now)
I've never shot on green with the 160a but have done many with the AF100 - keying always worked well.
 
I would shoot with the AF100 and position the talent well forward of the green screen. By throwing the background a bit out of focus it can help smooth minor variations and, therefore, key better.
