Dailymotion Video Downloader is a very good video downloader. It works with Dailymotion.com, a website where users can share their videos. It supports both standard and high definition videos. The codec used for videos allows for good quality and small file sizes, and with this tool you can download those videos.
The user interface couldn't really be simpler. You paste the URL of the video that you want to download and add it to the waiting list. Additionally, you can enable auto-downloads, so that new videos are downloaded instantly. I like the fact that this downloader can grab the HD versions of Dailymotion videos. This can be enabled simply by checking the right box. Another thing that I like is that you can select an output format for your videos and they will be converted for you automatically, with 0 user input. However, you can't really change the settings of the many conversion profiles available.
The website says that this is a free application. But I am unable to download more than a single video without registering the app.
All in all, this is a neat tool. It works well and videos downloaded and converted with it are playable and look good.
