Requant

Three choices. Nothing else to set.

Drop clips or a folder on the app. Pick one card. Click Shrink. That is the whole app. Your originals are never touched. The sizes below are one real 6K clip, 1.77 GB from the camera.

• High quality Same picture, smaller file

  For keying, heavy grading, or archiving the master. Every pixel as the camera recorded it.

  1.77 GB becomes 1.66 GB

• Medium quality Recommended

  For most work: YouTube, documentary, and interviews. Half the file, and the picture still holds up in lifted shadows.

  1.77 GB becomes 927 MB

• Low quality Saves the most space

  For rough cuts, proxies, or clips you will downscale. A quarter of the file. Some grain in deep shadows.

  1.77 GB becomes 488 MB

Measured, not guessed

Quality is the point, so we measure it. One 6K clip, 228 frames, decoded with RED's own SDK and checked pixel by pixel against the camera original. Higher dB means closer to the original. At the same file size, Requant kept more of the picture than any other way we tried, at every size.

Lift the shadows 3 stops and the Low card stays smooth where other files of the same size go blotchy. All three cards took about 7 seconds for the whole clip on an M3 Pro, on the CPU alone. Your originals are never changed.
