I'd guess it is an issue with ffmpeg. Can you run? ffmpeg -i project_video.mp4 What's the output?

[skylin008]

The output information is :bash ffmpeg:command not found.

there you have your reason. Moviepy relies on ffmpeg for reading/writing videos, see: http://zulko.github.io/moviepy/install.html

You need to install it first

[Zulko]

Note that in near future moviepy will also have its own ffmpeg version via imageio, as it used to, so you wont have ffmpeg in your binaries path but you'll still be able to use ffmpeg with moviepy.

Hi, got same issue, but I'm getting result on ffmpeg -i: ffmpeg -i test.mp4 ffmpeg version N-91240-g3769aaf Copyright (c) 2000-2018 the FFmpeg developers built with gcc 5.4.0 (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.9) 20160609 configuration: --prefix=./build/ --enable-cross-compile --cross-prefix=/usr/bin/arm-linux-gnueabihf- --arch=armhf --target-os=linux --enable-gpl --enable-libx264 --enable-static --enable-pic --extra-cflags=-I./x264/ --extra-ldflags=-L./x264/ --extra-libs=-ldl ...

I've installed ffmpeg from source: whereis ffmpeg ffmpeg: /usr/local/bin/ffmpeg

I'm closing this issue as it's rather old and it's unclear if this is even still an issue now.
