# Mix a BGM track into an MP4 video.
|
|
#
|
|
# Usage:
|
|
# bash add-music.sh <input.mp4> [--mood=<name>] [--music=<path>] [--out=<path>]
|
|
#
|
|
# Mood library (in ../assets/, matching bgm-<mood>.mp3):
|
|
# tech — Apple Silicon / product keynote vibe, minimal synth+piano (default)
|
|
# ad — upbeat modern, clear build + drop, social-media ad energy
|
|
# educational — warm, patient, inviting learning tone
|
|
# educational-alt — alternate take of educational
|
|
# tutorial — lo-fi background, stays out of voiceover's way
|
|
# tutorial-alt — alternate take of tutorial
|
|
#
|
|
# Flags (all optional):
|
|
# --mood=<name> pick a preset from the library (default: tech)
|
|
# --music=<path> override with your own audio file (wins over --mood)
|
|
# --out=<path> output path (default: <input-basename>-bgm.mp4)
|
|
#
|
|
# Legacy positional form still works: bash add-music.sh in.mp4 music.mp3 out.mp4
|
|
#
|
|
# Behavior:
|
|
# - Music is trimmed to match video duration
|
|
# - 0.3s fade in, 1.0s fade out (avoids hard cuts)
|
|
# - Video stream copied (no re-encode), audio AAC 192k
|
|
#
|
|
# Examples:
|
|
# bash add-music.sh my.mp4 # default: tech mood
|
|
# bash add-music.sh my.mp4 --mood=ad # switch mood
|
|
# bash add-music.sh my.mp4 --mood=educational --out=final.mp4
|
|
# bash add-music.sh my.mp4 --music=~/Downloads/song.mp3 # bring your own
