Beginning from the home video era up to the most cutting-edge standards of today, video file formats have undergone some major changes. Different file formats do different things, and the right video format for a specific file isn’t necessarily the right one for the others. Navigating the world of video file formats can get confusing, even more so when it comes to playing video on different types of devices. Not all videos can play on all types of devices. In fact, there are plenty of smartphones that can’t play FLV videos. Sample files for CSV, PDF, JPG and for all other file formats in multiple sizes can be downloaded for free!

Thats for the link Nicolae, unfortunatley the clip is only 704 x 480. I'm really after 1920 x 1080 clips to drive my system hard. Cheers.

very strange, maybe you've got some upscaling going on as mediainfo shows the following:

These are the best WMV encodes I've seen:
http://www.drfoster.f2s.com/trailers_hd-dvd.shtml
Though they're half or less the bitrate of HD DVD/Blu-ray.
You can find a lot of H.264 from apple:

Though they aren't the best encodes in the world.

I think VC-1 should show up as WVC1.

You need to be careful though, there's more to it than just the codecs, there's also the bitrates, those can make a huge difference in playability. For example, (if overclocked slightly) my HTPC can just play the Universal logo off King Kong, it averages about 9Mbps IIRC. However my HTPC chokes on King Kong itself, which averages about twice that (IIRC).
Oh, an H.264 is MPEG-4 AVC.
Over to you..... please help.[/quote]

Thanks Stanger. Agreed, the higher the bitrate the better, especially for the vc-1 and h264.
What i'm trying to do is simulate real life scenarios. ie h264 and vc-1 as if you were playing direct from hd-dvd or blueray disk.
And the others as you'd get rips from 'where ever' you get them from! :-) So 9mbps rips for wmv and mpeg4-avc would be fine cos thats what you normally get off the net.
I'm getting very confused regarding h264 and mpeg4-avc though. The samples i've listed as h264 show as 'h264' in mediainfo and play near on 100% gpu usage in powerdvd. yet some mpeg4-avc stuff (described as that in mediainfo) play with varying sucess with the powerdvd codec. I was under the impression that the mpeg4-avc stuff is known as h264 because it is encoded with the x264 encoder. And i 'thought' that the h264 is how you would find it on hd-dvd/BR? Is this correct??
If they are the same(h264 and mpeg4-avc), why do they show differently in mediainfo?

Thanks dr, will update the list.
Still struggling with h264 (created by x264). Anyone?

All can be played in Theatertek as well.

A video file format is a type of file format for storing digital video data on a computer system. Video is almost always stored using lossy compression to reduce the file size.

A video file normally consists of a container (e.g. in the Matroska format) containing video data in a video coding format (e.g. VP9) alongside audio data in an audio coding format (e.g. Opus). The container can also contain synchronization information, subtitles, and metadata such as title. A standardized (or in some cases de facto standard) video file type such as .webm is a profile specified by a restriction on which container format and which video and audio compression formats are allowed.

The coded video and audio inside a video file container (i.e. not headers, footers, and metadata) is called the essence. A program (or hardware) which can decode compressed video or audio is called a codec; playing or encoding a video file will sometimes require the user to install a codec library corresponding to the type of video and audio coding used in the file.

Good design normally dictates that a file extension enables the user to derive which program will open the file from the file extension. That is the case with some video file formats, such as WebM (.webm), Windows Media Video (.wmv), Flash Video (.flv), and Ogg Video (.ogv), each of which can only contain a few well-defined subtypes of video and audio coding formats, making it relatively easy to know which codec will play the file. In contrast to that, some very general-purpose container types like AVI (.avi) and QuickTime (.mov) can contain video and audio in almost any format, and have file extensions named after the container type, making it very hard for the end user to use the file extension to derive which codec or program to use to play the files.

The free softwareFFmpeg project's libraries have very wide support for encoding and decoding video file formats. For example, Google uses ffmpeg to support a wide range of upload video formats for YouTube.^[1] One widely used media player using the ffmpeg libraries is the free software VLC media player, which can play most video files that end users will encounter.

Sample Video Clips

List of video file formats[edit]

Name	File extension(s)	Container format	Video coding format(s)	Audio coding format(s)	Notes
WebM	.webm	Matroska	VP8, VP9, AV1	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	MP3, 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[2] de facto standard for web-based streaming video (over RTMP).
F4V	.flv	MPEG-4 Part 12	H.264	MP3, AAC	Replacement for FLV.
Vob	.vob	VOB	H.262/MPEG-2 Part 2 or MPEG-1 Part 2	PCM, 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 MPEG program stream format.
Ogg Video	.ogv, .ogg	Ogg	Theora, Dirac	Vorbis, FLAC
Dirac	.drc	?	Dirac	?
GIF	.gif	N/A	N/A	none	Simple animation, inefficient compression, no sound, widely supported
Video alternative to GIF	.gifv	HTML	any	none	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	none	Inefficient, not widely used.
AVI	.avi	AVI	any	any	Uses RIFF
MPEG Transport Stream	.MTS, .M2TS	AVCHD	AVCHD (MPEG-4 / H.264 )	Dolby AC-3 or uncompressed linear PCM	The standard video format used by many Sony and Panasonic HD camcorders. It is also used for storing high definition video on Blu-ray discs.
QuickTime File Format	.mov, .qt	QuickTime	many[3]	AAC, MP3, others[3]
Windows Media Video	.wmv	ASF	Windows Media Video, Windows Media Video Screen, Windows Media Video Image	Windows Media Audio, Sipro ACELP.net
Raw video format	.yuv	Further documentation needed	Doesn't apply	Doesn't apply	Supports all resolutions, sampling structures, and frame rates
RealMedia (RM)	.rm	RealMedia	RealVideo	RealAudio	Made for RealPlayer
RealMedia Variable Bitrate (RMVB)	.rmvb	RealMedia Variable Bitrate	RealVideo	RealAudio	Made for RealPlayer
Advanced Systems Format (ASF)	.asf	ASF	any	any
AMV video format	.amv	Modified version of AVI[4]	Variant of Motion JPEG	Variant of IMA, ADPCM	Proprietary video file format produced for MP4 players and S1 MP3 players with video playback
MPEG-4 Part 14 (MP4)	.mp4, .m4p (with DRM), .m4v	MPEG-4 Part 12	H.264, MPEG-4 Part 2, MPEG-2, MPEG-1	Advanced Audio Coding, MP3, others
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 (MP3)	Old, but very widely used due to installed base.
MPEG-2 – Video	.mpg, .mpeg, .m2v	?	H.262	AAC, MP3, MPEG-2 Part 3, others
M4V – (file format for videos for iPods and PlayStation Portables developed by Apple)	.m4v	MPEG-4 Part 12	H.264	AAC, Dolby Digital	Developed by Apple, used in iTunes. Very similar to MP4 format, but may optionally have DRM.
SVI	.svi	MPEG-4 utilising a special header	?	?	Samsung video format for portable players
3GPP	.3gp	MPEG-4 Part 12	MPEG-4 Part 2, H.263, H.264	AMR-NB, AMR-WB, AMR-WB+, AAC-LC, HE-AAC v1 or Enhanced aacPlus (HE-AAC v2)	Common video format for cell phones
