使用python在视频上滚动文本

from moviepy.editor import VideoFileClip, TextClip, CompositeVideoClip
from moviepy.video.tools import scroll

video_path = 'path/to/video.mp4'  # 视频文件路径
video = VideoFileClip(video_path)

text = '这是滚动的文本'  # 滚动的文本内容

text_clip = TextClip(text, fontsize=30, color='white', bg_color='black')
scrolling_text = scroll(scrolling_text, duration=video.duration)

video_with_text = CompositeVideoClip([video, scrolling_text])

output_path = 'path/to/output.mp4'  # 输出视频文件路径
video_with_text.write_videofile(output_path, codec='libx264')
