I'm doing a video and audio editing in python. Trying to convert an srt file to audio with timings. That's why I'm trying to do so that the talking parts are as long as the timings in the srt file. If they are not, I want to either speed up or speed down the parts. Here's what I have so far, the else part works perfectly fine but I can't seem to get the if part working.

Question

I'm doing a video and audio editing in python. Trying to convert an srt file to audio with timings. That's why I'm trying to do so that the talking parts are as long as the timings in the srt file. If they are not, I want to either speed up or speed down the parts. Here's what I have so far, the else part works perfectly fine but I can't seem to get the if part working. Why?

 

duration_of_dialogue = str(sub.end - sub.start)
time_datetime = datetime.strptime(duration_of_dialogue, "%H:%M:%S,%f")
milliseconds2 = (time_datetime.hour * 3600 + time_datetime.minute * 60 + time_datetime.second) * 1000 + time_datetime.microsecond / 1000
print("Duration should be ", milliseconds2)

text_duration_ms = len(audio_segment)
print("Current duration is ", text_duration_ms)

if text_duration_ms != milliseconds2:
    speed_change = milliseconds2 / text_duration_ms
   
    if speed_change > 1:
        audio_segment = audio_segment.speedup(speed_change)
    else:
        audio_segment = audio_segment.speedup(1 / speed_change)

    new_audio_segment = audio_segment.set_frame_rate(int(audio_segment.frame_rate * speed_change))
    audio_segment = new_audio_segment[:milliseconds2]
    print("New duration is ", len(audio_segment))
