很多剪辑软件要收费，自己写了一个。
from moviepy.video.io.VideoFileClip import VideoFileClip
def trim_video(input_path, output_path, trim_duration):
video_clip = VideoFileClip(input_path)
trimmed_clip = video_clip.subclip(0, video_clip.duration - trim_duration)
trimmed_clip.write_videofile(output_path, codec="libx264")
trimmed_clip.close()
video_clip.close()
input_video_path = "input.mp4"
output_video_path = "output.mp4"
trim_duration_seconds = 8 # 剪掉的秒数
trim_video(input_video_path, output_video_path, trim_duration_seconds)
参数设置：
video_clip.subclip(x,y):
x:开始时间
y:结束时间
input_video_path:输入文件路径
output_video_path:输出文件路径
具体实现：
上面的程序实现的是剪掉最后8s
