Ummy Video Downloader is a practical tool that allows you to download videos from YouTube in a very simple way. The program allows you to select the video's download quality and the local folder where it will be saved. Besides, if you want to download multiple videos, the program creates a download list automatically for you, though only one video is downloaded at once.
The program offers a very simple and intuitive user interface where you can paste the URL of the YouTube video you want to download. However, this is mostly not necessary, as the program includes a clipboard monitoring feature that pastes the video's URL automatically as soon as you copy it. Once this happens, the program shows you the video's still-image, which helps you be sure you will download the right video file. Finally, you can select the download quality (usually from low to full HD qualities available) and start the process.
Unfortunately, there are some disadvantages about Ummy Video Downloader that are worth mentioning. Firstly, the program seems to work only with YouTube videos, so you can't download videos from other similar video sharing websites. Secondly, although the program creates a download list for you, it only downloads a single video at once, as I mentioned before. And finally, all the downloaded videos are in MP4 format, though you can also select MP3 to extract the audio stream from a video file. In other words, if you require your downloaded video to be in other format rather than MP4, you would need to resort to a separate video converter.
To sum up, if your interest is to download videos from YouTube exclusive, and if it isn't a matter to you that the downloaded videos are in MP4 format - or if you just want to extract the audio stream from some YouTube videos in MP3 format, then Ummy Video Downloader might be the right tool for you, as it is free and very easy to use. However, if your needs go beyond the mentioned capabilities, I would truly recommend you to look for a more advanced video downloader.
