Puzzle #37 · Hard · 6 params

H.264 · Bitrate 8M · 1080p · AAC · MP4

The scenario

Podcast video recording with a static background (talking head + slides). H.264 at 8 Mbps with veryfast preset for real-time encoding, -tune stillimage for slide content optimization, AAC for podcast distribution on Apple Podcasts.

The answer

Video CodecH.264
Bitrate8M
Resolution1080p
AudioAAC
ContainerMP4
Presetveryfast

The command

ffmpeg -i input.mp4 -c:v libx264 -b:v 8M -preset veryfast -tune stillimage -c:a aac -b:a 128k output.mp4

Why

The -tune stillimage flag optimizes for content with very little motion — like slides or screencasts. It increases I-frame quality and adjusts the rate control to allocate more bits to scene changes (slide transitions) and fewer to static frames.
