Horrible result in Keylight on Canon C300 footage

[Petter Stahre]

I don’t know if this is possible in Keylight but if not, here is an alternative using Phyx Keyer which can be bought for AE (199$):

Just tell me when you want me to erase the link.

What I did was this:
– basic grading (sorry, a bit yellow 🙂
– since I suspect you don’t use camera movement for the shot I created a still image (screenshot after grading) without the singer, using Photoshop … which is a poor mans version of filming the empty green screen scene which of course would have been better. This was my quick-and-dirty version: test
– I let Phyx ScreenCorrector use that image to analyze differences between your shoot and the empty scene
– I then applied the Phyx Keyer and made a copy of the layer – one layer had settings for the upper body and one layer for the legs and feet.

I’m not satisfied with the shadows, they could benefit from other settings or a third layer, but for the test I stopped there since it’s also a matter of how you’re going to use the singer.

I would not be surprised if the same method could be applied in Keylight !?

I have keyed the Footage with a combination of several effects.

Check the Project File:

Hope you may like the result. If you unable to understand how and why the effects have been used, Feel free to ask again.

I just did some quick tests of my own, as I have to shoot greenscreen with a C300 tomorrow. Overall, pretty disappointing for a camera at this price point. I noticed crazy noise in Keylight also. Final Result is especially bad, but even Intermediate was unacceptable as far as noise is concerned.

It seems all the normal greenscreen rules are in effect with the C300, but moreso. It really doesn’t like fuzzy areas (soft focus, motion blur, hair), and it really doesn’t like underexposure. I read about the ‘Expose to the Right’ method (https://en.wikipedia.org/wiki/Exposing_to_the_right), and decided to give it a whirl. I did indeed get less noise by overexposing in camera and then darkening in post.

I tested Cinema Locked and EOS. After correcting the Cinema to match EOS as close as possible (SA Color Finesse, AE CS6), I still felt the EOS keyed better, but just slightly. Cinema seems to have some odd color shifting. Other users concur: https://www.dvxuser.com/V6/archive/index.php/t-287056.html

I didn’t test different light sources. Tungsten vs. Daylight might throw some wrenches into the mix.

The biggest improvement I found is to use Neat Video’s Reduce Noise plugin to cleanup the footage before pulling the key. I was very happy with that result. Neat Video: 1 Canon: 0

Hey,

take a look at my post “Mar 21, 2013 at 9:45:10 am” in this threat.
I key footage from DSLRs a lot and if you use the technic with the lumaMatte, the key is good!

Hope ths helps!

I’m using Auto Color, Denoiser II and Keylight and getting excellent results with C300 footage.

Thanks Jim. I think it´s a good solution for the worst. That works also for r3d files.

I spent thousands on this camera and am totally underwhelmed with the keying results however, I’m now using Neat Video’s reduce noise plug-in for AE2015 and am thrilled with the results. One extra step but for under $100 it’s worth it.
