I tried it and immediately fell in love! It was so easy to use! After a couple conversions I bought the guys a cup of coffee. A couple more and decided this was too good to abuse! I joined! My life is so much easier!Tillie

WEBM Video Format WEBM Converter
A WebM file is a video format that had been developed by On2 Technologies who were acquired by Google in 2009. The format itself is an open format and high quality but crucially, small in size.
WebM files have grown in popularity since HTML5 became standard for sites such as YouTube and for popular devices like the iPhone. The format itself is based on the Matroska format which is a multimedia container format. WebM, like an MKV format is made up of audio, video and subtitles in just a single file with each element having its own type of encoding around it.
WebM videos themselves are quite difficult to open in that most popular video players, besides the VLC player, do not play these formats without having to convert them first or installing specific software to get them to play.
MP4 Video Format MP4 Converter
An MP4 file is often called an MPEG4 file and it is used to store video and/or audio data. When iTunes launched in 2001 the MP4 file format saw a major boom in use. This is because it is the standard format for the majority of iTunes downloads. As well as iTunes causing a major increase in use, the Internet has also been behind its increased popularity as when a user downloads a video on the Internet it tends to be in the MP4 format. MP4 files are clever in their design in that they combine compression technologies which means they tend to be small in size which is another reason for their popularity.
An MP4 file is often known as a container format because of the way it is structured. MP4 files were the file type of choice for Apple’s iTunes mainly because of how efficient they are. In other words, they were small in size but still retained the quality of the audio and video elements. The reason for this is because the audio compression is handled differently from the video compression with the video compression being done using MPEG-4 whilst the audio compression uses AAC which actually helps to improve the audio quality. The increasing popularity of MP4 files has seen the creation of a number of MP4 players which are designed to play MP4 files.
