Part 13/15:

Graphs illustrating quality versus bitrate shape the planning of optimal encoding parameters. An ideal zone exists—often described as the convex hull—where size and quality are balanced optimally.

Practical Recommendations and Closing Insights

The overall advice emphasizes:

• Chunking videos at I-frames for parallel processing and minimal re-encoding.

• Forcing I-frames at strategic points—scene changes and regular intervals—to optimize quality and efficiency.

• Producing multiple variants and evaluating them perceptually rather than relying solely on objective metrics.

• Being mindful of resolution effects on compression efficiency.
