# 基本视频剪辑
from moviepy.editor import VideoFileClip

clip = VideoFileClip("input.mp4")

subclip = clip.subclip(10, 30)
subclip.write_videofile("output.mp4")

# 添加字幕文字
from moviepy.editor import TextClip, CompositeVideoClip
txt = TextClip("AI Skill Hub", fontsize=50, color='white')
txt = txt.set_pos('bottom').set_duration(5)
final = CompositeVideoClip([clip, txt])
final.write_videofile("output.mp4")

# 视频拼接
from moviepy.editor import concatenate_videoclips
clips = [VideoFileClip(f) for f in ["a.mp4", "b.mp4", "c.mp4"]]
final = concatenate_videoclips(clips)
final.write_videofile("merged.mp4")
