I have seen similar issues being reported and was fixed. @Zulko your help will be required. Thanks in advance

Update: Post this issue, Moviepy starts updating the progressbar in individual line. Example:

Hi, I have the same issue doing video concatenations. Is there any solution for this? In my case, this is happening with a video that has no audio and that is extremely short.

Thanks in advance !

@GMarzinotto, please provide the exact code that causes the issue and the complete error trace that you are getting. Thanks!
