Google “Matt Porwoll diffusion test” (can’t post links). TL:DR, magic cloth is largely not worth it. Eats up a ton of out put for a pretty minor difference.
You can use small non-parabolic softboxes as an extra layer of diff without any additional grip.
Hello,
May I suggest using low-hanging LED or flourenscent tubes. As you’re shooting B/W, there is much less reason to worry about color reproduction, so even the cheap consumer-grade ones from your local hardware store might do as long as they’re bright enough. Quality and contrast can be easily manipulated by hanging the fixtures lower or higher and the size of the tubes themselves.
Sony FX30 is cheaper and much better equipped for video capture than A7C while being almost as compact. BMPCC 6k pro is more expensive at 2500 $, has better ergonomics, a large, bright built-in monitor, ND filters, and can shoot raw out of the box, but lacks autofocus.
Neither slog curve was designed for 8-bit capture, and can exhibit some egregious color banding when shooting with an 8-bit codec. Fx30 has both 10-bit internal and raw via hdmi.
