Matched Content


  • YouTube has quickly become the go-to website for the online streaming of videos, by users from all across the world. It is a video sharing website that has made it increasingly more convenient for people to watch videos, or even upload their own to be shared by a mass audience. This has proven to be an extremely useful website for people who have also implicated their business ideas onto this application in the form of, YouTube channels. Some of these business ideas have caught attention of the public, which has made the owners, in some sense or the other, YouTube celebrities. In order to cater to such individuals requiring an excessive use of this website, the YouTube™ HD-LQ extension is introduced, which allows the users to view the videos available in full-HD or the lowest quality available (LQ).

    This is a lightweight extension that works with YouTube HTML5 and Flash players to incorporate different quality videos to be played on the site. This application can easily shift the quality from the toolbar popup and also provides the option to not change the quality at all as well (maintain the default quality). This can easily be implemented through the gear icon in the toolbar, accessing the quality options and setting the desired level. The HD level is useful where the internet speed is high enough to load large videos, whereas the low quality is supported when the content of the video is not as important and the bandwidth is not be waste. There is also an option on the application to automatically set the quality level for all videos. This option of quality has proven to be greatly helpful to users as it allows them the option of viewing the videos in different levels, which saves up time and internet usage. These specifications play an important role while dealing with habitual YouTube users, who watch and upload videos every day and need different specifications for different videos.
