I am creating a Python script which uses the MoviePy module, to take clips from a larger video and concatenate them together.
The times for the clips are detailed in a CSV file like so;
0,10
11,19
15,20
34,42 etc
What I have done is read the CSV file row by row and then using the subclip method from Moviepy created a clip which is stored in a list of clips, however I get a IndexError - list index out of range.
What could be the issue (the code works fine if I don't use the subclip method with the values from the CSV file)?
This is my code:
video= VideoFileClip('file')
clipsArray = []
import csv
with open('csv file', 'r') as file:
reader = csv.reader(file)
for row in reader:
startTime = row[0]
endTime = row[1]
clip = fullVideo.subclip(startTime, endTime)
clipsArray.append(clip)
The error message is:

CSV file:
0,12
16,21
22,29
34,59
89,130
140,160
162,171
The reason it failed is because when you read from this csv file you get startTime and endTime as strings, for instance '0' and '12' in the first line.
MoviePy only accepts two formats for times:
'hh:mm:ss.dd' (hours, minutes, seconds, decimals of seconds), e.g. '05:12:10.50' for 5 hours 12 minutes and 10.5 seconds.So you should write
startTime = float(row[0])
endTime = float(row[1])
clip = fullVideo.subclip(startTime, endTime)
