Convert DTS/TrueHD to Opus or AAC (Audio often takes up 20% of a file).

– higher CRF = smaller output.

In the world of video technology, "Shrinking HEVC" (High Efficiency Video Coding, or H.265) refers to the relentless pursuit of reducing the bitrate and file size of video content while maintaining visual fidelity. While HEVC was originally designed to double the compression efficiency of its predecessor (H.264/AVC), the industry has spent the last decade trying to "shrink" it further. shrinking hevc

: For HEVC, a CRF value between 20 and 24 usually provides an excellent balance.

Halving framerate (60 → 30 fps) can halve size. Use only if motion remains acceptable. ffmpeg -i input
