Frequently Asked Questions
Does resizing a LUT affect quality?
Downscaling (e.g., 65³ to 33³) may result in minor color accuracy loss, but it's usually imperceptible. Upscaling uses trilinear interpolation to maintain smooth color transitions.
Can I upscale a small LUT to improve quality?
Upscaling adds more data points through interpolation, which can result in smoother gradients. However, it won't add information that wasn't in the original LUT.
What LUT size should I use?
33x33x33 is the standard for professional video editing. Use 17³ for previews or when file size is critical. 65³ is for maximum accuracy in high-end color grading.
Will my LUT work after resizing?
Yes, the resized LUT maintains compatibility with all software that supports CUBE format. The only changes are the grid size and file size.
