| Name | File extension(s) | Container | Video coding format(s) | Audio coding format(s) | Notes |  |  |
| --- | --- | --- | --- | --- | --- | --- | --- |
| WebM | .webm | Matroska | VP8, VP9 | Vorbis, Opus | Royalty-free format created for HTML5 video. |  |  |
| Matroska | .mkv | Matroska | Any | Any |  |  |  |
| Flash Video (FLV) | .flv | FLV | VP6, Sorenson Spark, Screen video, Screen video 2, H.264 | எம்பி3, ADPCM, Nellymoser, Speex, AAC | Use of the H.264 and AAC compression formats in the FLV file format has some limitations and authors of Flash Player strongly encourage everyone to embrace the new standard F4V file format. De facto standard for web-based streaming video (over RTMP). |  |  |
| F4V | .flv | MPEG-4 Part 12 | H.264 | எம்பி3, AAC | Replacement for FLV. |  |  |
| Vob | .vob | VOB | H.262/MPEG-2 Part 2 or MPEG-1 Part 2 | துடிப்பு குறி பண்பேற்றம், DTS, MPEG-1, Audio Layer II (MP2), or Dolby Digital (AC-3) | Files in VOB format have .vob filename extension and are typically stored in the VIDEO_TS folder at the root of a DVD. The VOB format is based on the திரைப்படநுட்பத் திறவோர் குழு program stream format. |  |  |

| GIF | .gif | N/A | N/A | Simple animation, inefficient compression, no sound, widely supported |  |  |  |
| Video alternative to GIF | .gifv | HTML | Any | Not standardized, and not a real video file in the classical meaning since it merely references the real video file (e.g. a .webm file), which has to exist separately elsewhere. A .gifv "file" is simply a HTML webpage which includes a HTML5 video tag, where the video has no sound. As there were large communities online which create art using the medium of short soundless videos in GIF format, GIFV was created as a functionally similar replacement with vastly smaller filesizes than the inefficient GIF format. |  |  |  |
| Multiple-image Network Graphics | .mng | N/A | N/A | Inefficient, not widely used. |  |  |  |
| AVI | .avi | AVI | any | any | Uses RIFF |  |  |

| MPEG-1 | .mpg, .mp2, .mpeg, .mpe, .mpv | MPEG-1 part 1 | MPEG-1 part 2 | MPEG-1 Audio Layer I, MPEG-1 Audio Layer I, MPEG-1 Audio Layer III (எம்பி3) | Old, but very widely used due to installed base. |  |  |
| MPEG-2&nbsp;– Video | .mpg, .mpeg, .m2v | ? | H.262 | AAC, எம்பி3, MPEG-2 Part 3, others |  |  |  |
