Video DownloadHelper is the most complete tool for extracting videos and image files from websites and saving them to your hard drive.

Just surf the web as you normally do. When DownloadHelper detects embedded videos it can access for download, the toolbar icon highlights and a simple menu allows you to download files by simply clicking an item.

For instance, if you go to a YouTube page, you'll be able to download the video directly on your file system. It also works with most other popular video sites like DailyMotion, Facebook, Periscope, Vimeo, Twitch, Liveleak, Vine, UStream, Fox, Bloomberg, RAI, France 2-3, Break, Metacafe, and thousands of others.

Video DownloadHelper supports several types of streamings, making the add-on unique amongst Video downloaders: HTTP, HLS, DASH, … Whenever a site uses a non-supported streaming technology, Video DownloadHelper is able to capture the media directly from the screen and generate a video file.

Besides downloading, Video DownloadHelper is also capable of making file conversions (i.e. change audio and video formats) and aggregation (combining separate audio and video into a single file). This is an upgrade feature that helps pay for the free stuff (we need to eat too). You are not compelled to use conversion for downloading videos from websites, and you can avoid picking variants marked as ADP to avoid the need for aggregation.

7.4.0 のリリースノート

* Added aggregator tool

In some situations, on sites streaming separately video and audio, Video DownloadHelper is not able to recognize both streams as being parts of the same media and does not offer automatic aggregation. As a result, the user may end up with an audio or video-only file, depending on the chosen variant. When an audio-only and a video-only file have been downloaded, it is now possible to use the local aggregation tool to merge those two files to a single audio-video media file.

* Added Greek and Hungarian locales

* Fixed possible crash when downloading a HLS videos

* Updated all locales
