DeveloperGoogle(Initially developed by On2, Xiph and Matroska)
OverviewWEBM is a multimedia container used for both audio and video formats. It is open-source and royalty-free software due to this, it can be implemented and changed for improvement by any developer. It uses different codecs to compress files. For instance, for video streams compression it uses VP8 or VP9 video codecs and for audio streams, it uses Vorbis or Opus audio codecs. It provides videos of the highest quality and that too with real-time delivery. It provides users with the playback option on any device which is due to the low computational footprint. It is licensed under BSD(A family of acceptable free software licenses). Besides this, it has another project named as Webp for images.
Technical descriptionIts structure is based on the Matroska container. That is why it can support both multiplexing and de-multiplexing. It uses core technologies like HTML, HTTP and TCP/IP which can be easily implemented and this is the main reason for its success. VP8 and VP9 are highly efficient to provide video of the highest quality. It is cost-effective due to its greater efficiency for bandwidths. It is a substitute for H.264 and MPEG4 which are patented software and have copyright. Videos of this format allow playback but it is possible only in Android version 2.3 that is Gingerbread and above. When ‘Rockchip’ came into the market in 2001 it made possible the implementation of full hardware of 1080p. Also, LiVES video editor version 1.4.9 allows coding and deflating of videos in real-time.

OverviewIt is a video format based on the Microsoft Advanced systems format(ASF) and it is a sequel of video codecs. There are three varied codecs for this format. Actual WMA compression technique was developed only for internet streaming applications and it gave tough competition to RealVideo. The other compression techniques include WMV screen and WMV image which are designed for specialized content. These files are compatible with both Mac and Personal computers ;etc. This format attracts companies those want to sell audios and videos online due to DRM technology. This is the most popular among its family members. Interlaced videos can also be played using this video extension. There is an advanced version named WMA 9 which automatically comes into play when video resolution exceeds 300,000 pixels and the bitrate 1000 kbit/sec.
Technical descriptionIt is based on DRM(Direct Rights Management), thereby, it restricts users from making unauthorized copies that are often bought online from stores. HD DVD and Blu-ray Disc are formats for physical delivery which were adapted when WMV version was standardized by the SMPTE(Society of Motion picture and Television Engineers). It is now termed as VC-1. MPEG-4 AVC, AVS and MPEG-4 ASP are other competitors against this format. Furthermore, it can also provide support to the variable bit rate, average bit rate and constant bit rate. It enables makers to use non-square pixels as well. Lastly, it can process videos using frame interpolation in which intermediate animation frames are created between the existing frames.
