ffmpeg does not allow None as fps argument

[BreuerChristian]

Expected Behavior

I combine mp4 and mp3 and get that error

Actual Behavior

File "C:\X\venv\Lib\site-packages\moviepy\video\VideoClip.py", line 300, in write_videofile ffmpeg_write_video(self, filename, fps, codec, File "C:\X\venv\Lib\site-packages\moviepy\video\io\ffmpeg_writer.py", line 212, in ffmpeg_write_video with FFMPEG_VideoWriter(filename, clip.size, fps, codec = codec, ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\X\venv\Lib\site-packages\moviepy\video\io\ffmpeg_writer.py", line 86, in init '-r', '%.02f' % fps, ~~~~~~~~^~~~~ TypeError: must be real number, not NoneType

Steps to Reproduce the Problem

I am not familiar with the fps fancy stuff but i found out that the none is not allowed for ffmpeg as fps Thatfore i added the code in the function ffmpeg_write_video

if fps==None:
    fps=24

After that it worked
