This post recommended by MiniTool official website mainly distinguishes the differences between compressed and uncompressed video formats as well as the differences between lossy and lossless video formats. Moreover, it lists the common compressed video file formats.

What Is Data Compression?

In information theory, data compression, also called source coding or bitrate reduction, is the process of encoding data by taking advantage of fewer bits than the original representation. Such compression is either lossless or lossy.

Usually, a device that performs data compression is referred to as an encoder while one that performs data decompression is regarded as a decoder. The combination of encoding and decoding processes is known as a codec.

Besides, the process of reducing the size of a data file is usually named data compression. In the context of data transmission, it’s referred to as source coding. Encoding is done at the source of the data before delivery or storage.

Lossless Compression vs Lossy Compression

Lossless data compression reduces bits by identifying and eliminating statistical redundancy. Thus, no data is lost and file quality is guaranteed. On the contrary, lossy data compression reduces bits by deleting unnecessary or less important info. So, lossy compression has data loss and quality damage.

What Is an Uncompressed Video?

After learning what is compressed video, now let’s see what uncompressed videos stand for.

An uncompressed video is a digital video that either has never been compressed or was generated by decompressing previously compressed video. Usually, it is made use of by video cameras, video recording devices, video monitors, as well as video processors that perform functions like image resizing, rotation, deinterlacing, and text/graphics overlay.

Uncompressed videos are conveyed over various kinds of baseband video interfaces including HDMI, DisplayPort, DVI, and SDI. There are standards for the carriage of uncompressed video over computer networks.


An uncompressed video isn’t a raw video. The latter represents largely unprocessed data (e.g. without demosaicing) captured by an imaging device.

Video Container Formats

Most video codecs are used alongside audio compression techniques to save the separate but complementary data streams as one combined package using so-called container formats. The following are common video file formats together with their filename extensions.

  • Matroska: .mkv, .mk3d
  • MPEG-4 Part 14 (MP4): .mp4, .m4v
  • QuickTime File Format (QTFF): .mov, .qt
  • Advanced Systems Format (ASF): .asf, .wmv
  • Audio Video Interleave (AVI): .avi
  • Material Exchange Format (MXF): .mxf
  • MPEG program stream (PS): .m2p, .ps
  • MPEG transport stream (TS): .ts, .tsv
  • BDAV MPEG-2 transport stream (M2TS): .m2ts, .mts
  • Video Object (VOB): .vob
  • Enhanced VOB (EVO): .evo
  • 3GPP (3GP): .3gp
  • 3GPP2 (3G2): .3g2
  • Flash Video (F4V): .f4v
  • Flash Video (FLV): .flv
  • Ogg: .ogv, .ogx
  • WebM: .webm
  • RealMedia Variable Bitrate (RMVB): .rmvb
  • DivX Media Format (DMF): .divx
