[etherrawr]

This code freezes the first frame at the end but it should freeze the last frame at the end?

from moviepy.editor import *

mainclip = (VideoFileClip("C:/Users/Admin/Videos/ukulele.mp4")
            .fx( vfx.freeze, t='end', freeze_duration=2))

final = CompositeVideoClip([mainclip])
final.write_videofile("ukulele.mp4",fps=24,codec='libx264')

Expected Behavior

freeze the last frame at the end
