jcs Posted May 23, 2014 Share Posted May 23, 2014 http://nofilmschool.com/2014/05/6k-red-dragon-35mm-film-canon-5d3-magic-lantern-raw-atlantis/#more-82041 I'm currently testing the GH4 against 5D3 RAW and the FS700. Initial impression is how to soften some shots for the GH4- the opposite of the 5D3 H.264 (too soft). 5D3 RAW isn't full 1080p (which is what downsampled GH4 4K to 1080p represents (hits the Nyquist limit)), however it's just about right for actor close-ups. The FS700 AVCHD is almost full 1080p, but has some aliasing artifacts and 'black edges' at super-white boundaries (though has 14 stops DR and excellent slomo up to 240fps (not full 1080p + more aliasing (still excellent for what it is)). In the video test above, they test various softening filters for the Red Dragon at 6K. The 5D3 RAW footage will easily cut between film and softened Dragon 6K footage. I will test softening the 4K GH4 before downsampling to 1080p to see how well it can match 5D3 RAW (the GH4 has a little aliasing at 1080p native; blurred 4K before downsampling will be as alias free as possible. Mathematically, that's the correct way to downsample- low-pass filter (blur) then downsample. It's not clear if it will provide a visible difference vs. blurring after downsampling if the source material is already alias free (and the downsampling algorithm doesn't introduce aliasing)).

jgharding Posted May 23, 2014 Share Posted May 23, 2014 I've been using C100 recnetly, and have found applying a little fast blur makes it look nicer than when it's super sharp, even with sharpness off it's too sharp Quote Link to comment Share on other sites More sharing options...
