Moviepy disabling escape characters

[Azrielx86]

Expected Behavior

It's supposed to print the progress on a single line.

C:\Users\edgar\Desktop>python test.py
>56.00% (56 of 100)

Actual Behavior

But when importing it, escape characters are ignored.

C:\Users\edgar\Desktop>python test.py
>0.00% (0 of 100)
>1.00% (1 of 100)
>2.00% (2 of 100)
>3.00% (3 of 100)
>4.00% (4 of 100)
>5.00% (5 of 100)
>6.00% (6 of 100)
>7.00% (7 of 100)
>8.00% (8 of 100)

Steps to Reproduce the Problem

from time import sleep
from moviepy import editor as mp

def print_progress(progress, current, end):
    print(f'\033[K>{progress:.2f}% ({current} of {end})\033[F\n', end='')
    sleep(0.2)

end = 100
for i in range(end):
    print_progress(i * 100 / end, i, end)

It only happens when importing moviepy.

Sorry, can you explain a bit better what (you think) this has to do with MoviePy? I'm having trouble identifying the underlying problem from your description, so can't tag this issue.

Your issue reminds me of #1751, please look at my comments there and report back here (or close the issue if it turns out your problem is of the same nature).

Closing due to lack of response.

@keikoro Hi, I came across the same issue. It seems like moviepy disables ANSI escape code on the command line. For example, the following code uses escape code to generate orange output in terminal:

print('\u001B[38;2;255;128;0m hello \u001B[39m')

But once moviepy is imported, the color is no longer displayed:

import moviepy

print('\u001B[38;2;255;128;0m hello \u001B[39m')

This issue can be reproduced on windows Terminal (not on PyCharm). Maybe this library changes the terminal running environment? I have no idea.

@wzy1935 Thanks for the helpful comment. I'll reopen the issue – could you still add your system/install specs to yours (like in our issue templates)?

@keikoro Sure,
