File nippyfile mp4

It seems like you're trying to refer to an MP4 video file named "nippyfile." However, because I'm a text-based AI and cannot handle files or perform file operations directly, I can't open, play, or manipulate video files. If you need assistance with something specific regarding an MP4 file, such as editing, converting, playing, or troubleshooting issues, please provide more details, and I'd be happy to help!
