A thorough study of Cine4

In this lesson we’ll focus on just one picture profile – Cine4 – against four color spaces:

  • Cinema (the one Sony wants you to use with it)
  • Matrix 709 (Rec. 709)
  • Pro (Rec. 709)
  • S-Gamut (for S-Log2, but let’s see for ourselves!)

Cinema Color Space

Here’s what Cine4 looks like, in the Cinema color space (In this order: -4, -2, 0, +2, +4, click to enlarge):

Who wins? Look for these things:

  • Which has better texture in the underexposed regions?
  • Which looks better when clipped either way? Is there a good roll-off at either end?
  • Which as more dynamic range?
  • Which has better skin patches?
  • Which has a better look overall?

Try to at least answer the above before reading the next. Otherwise I’ll be putting words in your head. Here’s a tip: Study each exposure point against the others. E.g., study all -2s together, then 0s together, and so on.

What I think

Cine4 has the best highlight dynamic range, though it turns yellow. In this test Cinema color space does much better than S-Gamut. All this shouldn’t be very surprising, because the way it is designed, all Cine profiles are intended to be used with the Cinema color space. Cine 4 also has lesser shadow dynamic range than Cine2.

Here’s the official wording from Sony:

Strengthens the contrast in dark parts more than [Cine3]. The contrast in dark parts is lower and the contrast in bright parts is higher than for [Movie].
