Float provides the most accurate video scope readings.

The Video Scope bit-depth menu.

At the bottom right corner of the Lumetri Scopes is a small menu called “float.” This controls the detail visible in the video scopes. Here’s how to set it.

  • 8 Bit. Displays all values on a 0 – 256 scale on the right, IRE on the left.
  • 10 Bit. Displays all values on a 0 – 1024 scale on the right, IRE on the left. Video values remain the same, what’s different is the amount of precision in the values.
  • Float. Displays all values on a 32-bit scale (±2.14 million values).
  • HDR. Displays all values on a scale from 0 – 10,000 (10K). (HD media uses a scale of 0 – 100.

While the scales are different, the display is essentially the same. For non-HDR work, use float. For HDR HLG or PQ use HDR.

NOTE: This setting does not affect your video clips or output.
