The quality-size tradeoff
H.264 CRF (Constant Rate Factor) encoding allows precise quality control. At 85% quality (CRF ~22), a video can be 40-60% smaller than the original with virtually no visible difference on standard screens.

Frequently Asked Questions
At what quality setting is loss invisible?
For most content on standard screens: 80%+ quality (CRF ≈20) is imperceptible. At 75%+, loss is very subtle. Below 65% (CRF ~30), some softening appears.
How much can I reduce size at 85% quality?
Typically 40-60% size reduction at 85% quality — keeping the same resolution. Results vary by content type.
Is this truly lossless?
No — re-encoding always involves some loss. "Visually lossless" means the difference is undetectable to the human eye in normal viewing conditions.
What content type benefits most from high-quality compression?
Cinematic footage, nature videos, and footage with fine detail benefit most from high quality settings. Screen recordings and animations can use lower quality with minimal visible effect.
