17³, 33³, 65³: when to use each LUT size
LUT size affects precision and processing load. Bigger is not always better; delivery and speed matter.
How size influences grading fidelity
17³ is fast and lightweight and works for many real-time workflows.
33³ is a strong default compromise for most creators.
65³ can produce smoother transitions in high-detail pipelines but uses more compute and storage.
- Use 17³ for quick grading previews and draft cuts.
- Use 33³ for most online content and client proofing.
- Use 65³ when subtle tonal transitions are critical.
Decision guide
If your final timeline is heavy with graded shots and motion details, start at 33³ then benchmark 65³ only if needed.
Common Questions
Is 65³ always better?
Not always. The visual gain can be small in many workflows, so choose based on final output and processor limitations.
Does bigger LUT mean stronger grade?
No. Size only affects interpolation precision, not creative intent.
