So is there any way to slow down a YouTube video? Well, there are some media players like VLC, or HTML player which you can use to slow down playing speed during playback. But if you're looking for a way to slown down YouTube video permantly for other uses, here is your  way: add slow motion to YouTube videos with a slow motion video editor  - Wondershare Video Editor (Video Editor for Mac) (Windows 8 supported).

1 Download YouTube with Free YouTube Downloader

First of all, you should know that this is not a method to slow down online YouTube video. You have to download YouTube videos to your hard drive first. Many free apps do the job. For example, Wondershare Free YouTube Downloader and Video DownloadHelper (Firefox Add-on).

2 Add video files to the program

Download and install Video Editor and it totally supported the downloaded YouTube videos (usually in FLV). You can either click "Import" on the primary windows and select YouTube FLV video file from your computer, or simply drag and drop YouTube FLV file to the User's Album. Next, drag YouTube video from User's Album to Timeline for editing. Besides slow motion for YouTube video, Video Editor comes with powerful features such as adding titles, photos with transition, applying visual effects, Picture-in-Picture video, and so on.

On the Timeline, double click on the added YouTube video to open up the video editing panel. You will see the Speed option, and the speed number indicates fast or slow motion. Move the little triangle button to 0.5 and you get a slow down version of the YouTube video. Click Play button in the preview windows to have a look at the new YouTube video.
