Based on the exposure of the greenscreen and the colours in the plate I’m not the least bit surprised that that is the result you are getting from Keylight.
You are going to need to do some garbage roto around the window.

Knowing what you need to do to make something correct is an important skill as a VFX artist. Knowing what you can get away with is equally important.

Well if you use the layer with the flashes in, there will be light patches from different parts of the screen, so that will add a bit of directional light.
It’s never going to be perfect Dave. I know it’s good to strive for perfect, but as long as you sell the effect it’s good enough. Flashing the whole layer should be enough to get the message across. Especially if you can lift the existing shadows, and it’s quick.

Can you create a high contrast version of the layer with the flashes in? Crush out all of the blacks until all you can see are the flashes. Then you can take this layer, blur it, grade it, scale it, whatever, and add/max/screen it on top of your model. Then you have flashes whenever there are flashes.
You could even pull a key of your shadows, and use another copy of this layer set to max, to fill them in and keep Dave happy.

It’s something at the Youtube end, not a compression problem. Have at look through our Youtube settings to see if you can change the default. I know you can in Vimeo. I’d check, but I can’t sign into my Youtube account at work.
All of my Youtube videos are loading in SD by default too.

That video defaulted to SD, once I changed the playback to HD it looked a lot better. The logo in the corner looked fine. The only issue I could see where he crunchy edges around the presenter, which looked like it was due to your key, not compression.

I looks like it can be done if you launch the render from the command line with increment flag
increment is the number of frames to advance before rendering a
new frame. A value of 1 (the default) causes normal rendering of
all frames. Higher values render a frame and use it increment
times in output, and then skip ahead increment frames to begin
the cycle again. Higher values result in faster renders but
choppier motion.I’m looking at page 610 of the After Effect CC manual.

I don’t know how to render every other frame from After Effects. But I do know it is a legitimate technique to check heavy renders, especially for 3D work.
If you ever figure out how to render every other frame you can then use the ‘skip existing frames’ option to go through and fill in the empty spaces.
If there is no way to get After Effect to render skipped frames, you could always do your frame rate trick, and then write a script in Automator or Bridge or something that renames the files with some maths. I think the maths would be (x*2)-1 but check that.

I’ve never had issues using Screen in Nuke with values greater than 1 (assuming we don’t have negative values), and we always work floating point.
