I am not a Python expert and all that. I just needed to learn how to combine videos with subtitles, so as not to look for online services for this. I found a simple code for this on the Internet. And I was stunned by how badly it works.

code:

import imageio
import pysrt
import sys
import os 
from moviepy.editor import *

video = VideoFileClip("C:\\yt-dlp\\PC Engine Emulator Full Setup Guide [Ares].webm")
subtitles = pysrt.open("C:\\yt-dlp\\PC Engine Emulator Full Setup Guide [Ares].srt", encoding='utf-8')
subtitle_clips = []

for subtitle in subtitles:
    
    text = subtitle.text

    start_time = subtitle.start.seconds + subtitle.start.milliseconds / 1000.0
    end_time = subtitle.end.seconds + subtitle.end.milliseconds / 1000.0
    duration = end_time - start_time

    text_clip = TextClip(text, fontsize=24, color='white', font="Arial")
    text_clip = text_clip.set_position(('center', 'bottom')).set_start(start_time).set_duration(duration)
    
    subtitle_clips.append(text_clip)

final_video = CompositeVideoClip([video] + subtitle_clips)
final_video.write_videofile('C:\\yt-dlp\\PC Engine Emulator Full Setup Guide (Ares).mp4')

I had to downgrade the moviepy module. Look for an older version of ImageMagick. And other dances with tambourines. In general, this simple code still does not work. Of course, there is a log. Does anyone have any ideas on how to learn to combine videos with subtitles using Python?

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.2.2 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.
