When I use ColorClip and TextClip in MoviePy, I get the "UFuncTypeError" issue

[JajaRodriguez]

When I want to render a ColorClip element into a video with a TextClip element, I get a very interesting error. There are no problems when I use the TextClip by itself.

Code:

from moviepy.editor import * video = VideoFileClip("intro.mp4") get = video.subclip(0, 10) text_clip = TextClip("Hello World", size = (100,100), color = 'black') text_clip = text_clip.set_duration(9) set = CompositeVideoClip([get,text_clip]) color_clip = ColorClip(size = (100,100), color='gray') color_clip = color_clip.set_opacity(.8) color_clip = color_clip.set_duration(9) set = CompositeVideoClip([get,color_clip,text_clip]) set.write_videofile("moviepy.mp4",codec="libx264")

Output and Error:

Please always include your specs like we ask for in our issue templates – MoviePy version, platform used etc. – and code-format code samples to improve readability, thanks.

In 7th line, change it to -> color_clip = ColorClip(size = (100,100), color=(64,64,64)). Basically, try color in RGB format.
