video-subtitles-and-audio-insert-workflow

Burn hard subtitles from UTF-8 SRT files using moviepy 2.x with CJK-capable system fonts; tune font size, placement, stroke, and encode settings (bitrate or CRF) to avoid oversized outputs. Documents ffprobe/ffmpeg workflows for inspection, encoding, and batch jobs; troubleshooting for fonts, bitrate, and pacing. Covers voiceover with edge-tts (voice selection, rate/volume/pitch), matching narration length to video with atempo/apad, and multi-scene pacing with breathing room. Targets moviepy 2.x and Python 3.x on macOS, Linux, and Windows.
