MoviePy error: FFMPEG encountered the following error while writing file C:/Users/Ben/Downloads/test_RealESR_Gx4_Resize-100_Interpolation-Low.mp4:

b'[mp4 @ 000001deccbcdc00] Could not find tag for codec pcm_s16le in stream #1, codec not currently supported in container\r\nCould not write header for output file #0 (incorrect codec parameters ?): Invalid argument\r\nError initializing output stream 0:0 -- \r\n'

The video export failed, possibly because the codec specified for the video (libx264) is not compatible with the given extension (mp4). Please specify a valid 'codec' argument in write_videofile. This would be 'libx264' or 'mpeg4' for mp4, 'libtheora' for ogv, 'libvpx for webm. Another possible reason is that the audio codec was not compatible with the video codec. For instance the video extensions 'ogv' and 'webm' only allow 'libvorbis' (default) as avideo codec.
