Domande frequenti su Compressione video
What does the CRF value mean?
CRF (Constant Rate Factor) determines quality. 18 is nearly lossless, 28 is moderate compression, and 40 is high compression.
Consigli per usare Compressione video efficacemente
CRF values of 23-28 provide the optimal balance between file size and quality.
Lowering resolution (e.g., 1080p to 720p) can further reduce file size significantly.
Long videos take more time to process; trim to the needed portion first, then compress.
