Rated 5 out of 5 stars

The advantage to Complete YouTube Saber (CYS) over other YouTube video downloaders is that it allows you to download a video in the highest resolution possible for that video. It also provides a host of additional download options. In order to accomplish all this, CYS relies on an external program called "FFmpeg."

CYS achieves full functionality only after you download and save the FFmpeg program to your computer. The program doesn't actually install; it just sits in the folder where you've saved it.

To his credit, the developer provides an interface within the add-on to facilitate the download. Unfortunately, the interface is somewhat confusing and defaults to an option to download FFmpeg in a format that requires you to install another program just to decompress the download. Who needs that?

It's best to avoid the built-in interface and download the latest version of FFmpeg manually. Go to the FFmpeg download site at

https://ffmpeg.zeranoe.com/builds/

Select the appropriate options and click on the "Download FFmpeg" button. You'll get a zipped folder which can be decompressed in the usual way.

After you've saved the unzipped FFmpeg folder to the location of your choice, select the "FFmpeg" tab in CYS, select the option "I have already downloaded FFmpeg," and enter the location where you've saved it. Your file path will conclude with the "bin" folder of your unzipped download, within which the file "ffmpeg" resides.

This review is for a previous version of the add-on (5.7.34). 

Thanks for the 5 stars!!
