使用日期列表在python中为mp4视频添加时间戳/标签

Question

我有一个MP4视频文件(Amundsen.MP4(，我在谷歌地球引擎中创建了它——一个时间推移和每个图像的日期列表(dates.txt(——不是所有连续的日子。

我想用这个日期列表在python中为视频中的每一帧加上时间戳。有人能建议我怎么做吗，或者给我一个这样做的教程吗？我还没有找到关于如何以这种方式处理视频的资源。

感谢评论，我成功了。这是我成功的代码

from moviepy.editor import *
clip = VideoFileClip("myvideo.mp4")  
text_list = list3 # List of dates
clip_list = []
for text in text_list:
try:
txt_clip = TextClip(text, fontsize = 70, color = 'red').set_duration(1)
clip_list.append(txt_clip)
except UnicodeEncodeError: #Unsure if this part is necessary, took from elsewhere to address someone else's issue, but doesn't cause a problem
txt_clip = TextClip("Issue with text", fontsize = 70, color = 'red').set_duration(1) 
clip_list.append(txt_clip)

datevideo = concatenate(clip_list, method = "compose")
video2 = CompositeVideoClip([clip, datevideo])
#Write video
video2.write_videofile("videotest.mp4", fps = 1, codec = 'mpeg4')
# show video here embdeedded
#video2.ipython_display(width = 280)
