CRF vs Bitrate Trade‑offs
When to use CRF
General delivery with variable size
Better visual consistency clip‑to‑clip
Simpler workflow for YouTube/TikTok
When to use bitrate
Email/platform size limits
Predictable output for strict constraints
Consider two‑pass for accuracy
Recommendations
YouTube/TikTok: CRF 22–28 + preset medium/slow
Email: two‑pass with 480p and modest audio bitrate
Test short segments and compare visually
