The encode can’t save the film’s narrative problems.

The "spiral x264" blog post by developer Jason Garrett-Glaser explores the complex, iterative trade-offs between video compression efficiency, performance, and visual quality. It details the internal decision-making of the x264 encoder, particularly how settings influence motion estimation and rate-distortion optimization (RDO). spiral x264

Encoding speed and quality are inversely related; slower presets yield higher quality per bit. The encode can’t save the film’s narrative problems

If your video won't play on an old iPhone, TV, or Raspberry Pi, you need to restrict the Profile and Level.
