Pick renditions on the convex-hull of bitrate-quality curve. Per-title saves 30-50% bandwidth.
What you're seeing
Old: fixed ladder (240p, 480p, 720p, 1080p) regardless of content. Animated content needs more bits; static content less. Per-title encoding: analyze each video, pick renditions on the optimal bitrate-quality curve.
Netflix popularized this 2015+. Modern: per-shot encoding (different bitrates per scene).
★ KEY TAKEAWAY
Per-title encoding optimizes the rendition ladder per content. Saves ~30% bandwidth vs fixed ladders.
▶ WHAT TO TRY
- Slide Complexity — simple content needs less bitrate per resolution.
- Higher target VMAF → larger ladder.
