"""
|
||
生成通用片尾动画
|
||
支持三种尺寸：16:9、3:4、9:16
|
||
|
||
用法:
|
||
# 16:9 横版（默认）
|
||
manim -qh --format=mp4 --fps=30 -o outro.mp4 outro_generator.py OutroAnimation
|
||
|
||
# 3:4 竖版
|
||
manim -qh --format=mp4 --fps=30 -o outro_3x4.mp4 outro_generator.py OutroAnimation3x4
|
||
|
||
# 9:16 竖版（手机全屏）
|
||
manim -qh --format=mp4 --fps=30 -o outro_9x16.mp4 outro_generator.py OutroAnimation9x16
|
||
|
||
加语音（每种尺寸都要加）:
|
||
edge-tts --text "点关注，不迷路！" --voice zh-CN-YunxiNeural --rate="+10%" --write-media outro_voice.mp3
|
||
ffmpeg -y -i outro.mp4 -i outro_voice.mp3 -filter_complex "[1:a]adelay=1000|1000,apad=whole_dur=5.2[aout]" -map 0:v -map "[aout]" -c:v copy -c:a aac outro_with_voice.mp4
