如何使用Python-Moviepy向视频添加多个文本（字幕）？

Question

在某些情况下，我们需要向视频添加字幕。就我而言，我正在处理与视频描述（字幕）相关的问题。此 python 代码有助于向视频添加字幕。我想知道是否有人需要解决方案，请随意来试验代码。

import moviepy.editor as mp


my_video = mp.VideoFileClip("video.mp4") #video path
w,h = moviesize = my_video.size
my_text = mp.TextClip("A man and a women are sitting on a bench", font="Amiri-regular", color="white", fontsize=34)
txt_col = my_text.on_color(size=(my_video.w + my_text.w, my_text.h+5), color=(0,0,0), pos=(6,"center"), col_opacity=0.6)
txt_mov = txt_col.set_pos( lambda t: (max(w/30,int(w-0.5*w*t)),max(5*h/6,int(100*t))) )
final = mp.CompositeVideoClip([my_video,txt_mov])
final.subclip(0,17).write_videofile("final.mp4",fps=24,codec="libx264")

这对于单个标题很有效。您可以使用参数进行更改

"""Multiple Text in single video"""

 
import moviepy.editor as mp


my_video = mp.VideoFileClip("/home/user/cap/video.mp4").subclip(0,10)
print(my_video.duration)
w,h = moviesize = my_video.size

texts = []
with open("/home/user/cap/caption.txt") as file:
    for line in file: 
        line = line.strip() #or some other preprocessing
        texts.append(line)

print(type(texts))

starts = [0,2,4,6,8,10,12,14,16,18,20] # or whatever
durations = [2,2,2,2,2] #Time duraton between captions
t = 0
txt_clips = []
for text,t,duration in zip(texts, starts, durations):
  txt_clip = mp.TextClip(text,font="Amiri-regular", color="black", fontsize=29)
  txt_clip = txt_clip.set_start(t)
  txt_col = txt_clip.on_color(size=(my_video.w + txt_clip.w, txt_clip.h+5), color=(0,0,0), pos=(6,"center"), col_opacity=0.6)
  txt_clip = txt_clip.set_pos( lambda t: (max(w/30,int(w-0.5*w*t)),max(5*h/6,int(100*t))) ).set_duration(duration)
  txt_clips.append(txt_clip) 
  print(txt_clips)
  print(type(txt_clips))

   
final_video = mp.CompositeVideoClip([my_video, txt_clips[0],txt_clips[1],txt_clips[2],txt_clips[3],txt_clips[4]])

final_video.write_videofile("TEXT.mp4",fps=24)
