Matched Content


  • Video Prime (formerly named Download Helper) is a multi-browser Addon (Firefox, Chrome, Opera) that enables you to download HTML contents easily from your browser toolbar popup. It captures the contents seamlessly and almost instantly on many pages. Once an item is captured, the badge icon shows the number of captured items, and the popup window (once opened) shows each content as a card item. For Opera and Chrome browser, there is an optional settings that, if enabled, will calculate and show the resolution for each video item. Unfortunately this option is not yet available for Firefox browser as the HTML5 video element is not fully compatible with Firefox and may introduce some instabilities (unexpected crashes). However for Firefox browser, you can adjust the storage location to your desired choice. To do so, please open the settings page and choose your desired folder. This option is not available for Opera and Chrome as these browsers do not let the extensions to have access to the local folders of your computer. Another useful setting in this addon is the ability to add, edit or remove media file formats. There are several default media file formats added to the addon, but you can edit this list at any time. Some of these formats are as following.

    According to Wikipedia, a media (video, audio, etc.) file format is a type of file format for storing digital data on a computer storage system. The media can be stored in the Original or Compressed form to reduce the file size. A media file normally consists of a container format which containes video data in a video coding format alongside audio data in an audio coding format. The file format can also contain other information such as, subtitles, metadata (i.e. title) etc. Some file formats are designed to enable the user to choose which program will open the file. That is the case with some video file formats, such as WebM (.webm), Windows Media Video (.wmv), and Ogg Video (.ogv). But some very general file format types such as AVI (.avi) and Quicktime (.mov) can contain media in almost any format, which makes it hard for the user to choose the specific player and for the player to choose the right codec. For this reason, a free software called FFmpeg is designed and introduced to perform the encoding and decoding almost any file format. In general, FFmpeg is a multimedia framework which is able to decode, encode, transcode, mux, demux, stream, filter and play almost any type of media. It can work and be compiled on any operating system such as, Windows, Linus, Mac, Solaris and etc. The FFmpeg project's libraries have very wide support for encoding and decoding media (video, audio, text and etc.) file formats. Many famous companies and software such as Google and VLC player use FFmpeg libraries to encode and decode their media files. Some of the most famous and very useful media file formats are as following. (1) WebM which is a free file format created for HTML5 video. It is basically an alternative to HTML5 video tag. The development of WebM is sponsored by Google. It is supported by famous browsers such as Google Chrome, Mozilla Firefox and Opera. Many media players such as VLC and MPlayer fully support WebM files. Moreover FFmpeg can encode and decode WebM files. (2) FLV or Flash video Adobe Flash Player to deliver content. FLV may also be embedded within SWF files. In general, there are two different video file formats known as Flash Video: FLV and F4V which both are supported in Adobe Flash Player. (3) AVI or Audio Video Interleaved, is a media format introduced by Microsoft. AVI files can contain both audio and video data in a file and like the DVD video format, they support multiple streaming audio and video and can be tagged with metadata. (4) MPEG or MP4 is a very common file format that can store video, audio, subtitles and still images. It also allows streaming live over the internet. The MP4 was originally designed based on QuickTime file format and revised completely in the following years to be generalized into ISO file format (a general structure for time-based media files). (5) WMV or Windows Media Video is a media format developed by Microsoft. It was initially designed to stream media over the net similar to realvideo and in the following years, was adopted for delivering media such as DVD and Blu-ray. WMV is one of the most recognized media formats and is widely used by many companies and softwares.
