You could read a two page article and know the differences between competing video formats. When video went digital though, everything went out the window. Suddenly there was a bewildering array of video formats —. How’s anyone supposed to keep it straight? Possibly one of the most confusing things about digital video formats is the idea that there’s a “container” and “codec. The plethora of video formats mean that whatever type of video production you’re doing, there’s a good way to make it happen.
Twenty years ago everybody was watching movies the same way — either on a screen via a projector, or on a television set. Today many, many more options exist and people are taking advantage of them all. From high-end HD video with surround sound shown in a top of the line home theater to video streaming from a cellphone, video is everywhere and having a grasp of the various formats will ensure that your video gets where it needs to in the best way.
Trying to figure out exactly what containers and codecs are can be a little bewildering because it’s a very technical subject.
You can think of containers as a type of publication — a hardback book, a glossy magazine, a newspaper, a pamphlet, a gum cideo — all of which can contain words and other things like photographs, or cartoons, and yet each one works in a different way.
Think of the codec as the way of displaying the information you want in your publication. You can, for example, print War and Peace on Bazooka Joe bubble gum wrappers, but it will take thousands and thousands of them and nobody will want to read it that way; in the filetyype way you can put your vacation footage on an uncompressed DV format, but you won’t be able to decorer it over the web.
Similarly, you likely want your copy of War and Peace to be beautifully videp in hardback, but that’s not the proper container for a takeout menu someone’s going to shove in your mail slot. Words with drawings could properly be placed in a comic book, or a hardback book, or a newspaper, but the images in an art catalog or high-end fashion magazine require heavy-weight glossy paper to reproduce properly.
Every video application has a proper codec filerype container. To add one more layer of complexity: One thing that further complicates this is that some containers and some codecs are proprietary which means that there are occasional licensing issues about using one type of container with another type of codec.
In the past few years, the dust has somewhat settled on the video format wars with formats like DivX and mpeg-1 falling by the wayside and h. However confusing it is now, it used to be worse. Image of woman with close up inset showing artifacts. Usually, when video data is compressed, some of it is lost. Video compression software works by looking for redundancies in a frame, such as one bit of blue 11080p next to another bit of blue sky, and representing the redundancies together.
At very high rates of compression this becomes obvious, but at lower rates it’s difficult for people to notice. There arises a desire in every movie maker to try to use lossless formats, which preserve all the original data, but the compression ratios aren’t good enough yet to make them practical. Choices at the moment are to use the highest quality compression available for your intended purpose and to have multiple versions of your files for multiple uses — i.
When compressing for export, keep your video as high a quality as possible.
Export video at a smaller size in order to reach a certain platform, e. The highest quality video format is going to be the format you captured your video in. While digital files do not degrade in quality during copying, every time they are compressed with a lossy compression they lose data, so converting your uncompressed HDV formatted files even into a high quality MP4 will result in a loss of quality.
While it’s necessary to compress files in order to be able to share them, you should avoid re-compressing any more than you have to. Keep your master files in the original format; edit and create versions at whatever sizes necessary — but always from the originals. Don’t burn a Blu-Ray from a file that’s already been compressed into a low resolution file for streaming over the internet, instead create a separate, high resolution, file from your editing software.
A lot of the work in deciding how to compress video files can be done by your video editing software. Interface showing drop down menus for compression type. We’ll take a look at some containers and then at some codecs. A video’s file extension usually refers to the container.
A few containers have codecs that they almost always use and other containers are often used with many flletype codecs. Developed by Microsoft and released with Windows 3. Short answer, don’t output video to it, but keep a player handy.

ASF is a proprietary Microsoft container that usually houses files compressed with Microsoft’s WMV codec — to make things confusing, the files are usually designated. It was designed for streaming video from media servers or over the Internet. Short answer, again, don’t output video to it, but keep a player handy.
QuickTime was developed by Apple and supports a wide variety of codecs. It’s a proprietary format though and Apple decides what it supports. Quicktime, like Microsoft’s version. Most people will be able to read. AVCHD is a very popular container for data compressed with h.
It’s a file based format, meaning that it’s meant to be stored and played back on disks or other storage devices such as compact flash drives or SD cards.
It supports both filetyps definition and a variety of high definition variants from to p in a variety of frame rates including 60 frames decode second, 24p native as well as 3D modes. It’s filwtype extraordinarily robust container format 180p includes not just things like subtitles, but menu navigation and slideshows with audio. Flash was originally created by a company called Macromedia which was acquired by Adobe in Flash has been around for a while and comes in multiple versions, some better than others.
Older Flash video often uses the Sorenson codec, newer Flash uses h. It looked really cool, but it didn’t work with everything.
It is used, among other places, when distributing content from iTunes. As a result, many non-Apple devices such as my Sharp television will refuse to play. However, the formats are so similar that in instances where the DRM isn’t being used, simply changing the file extension to. Doing this will cause Apple Quicktime based applications such as Apple TV to be unable to find some contents of the file, namely chapter markers and AC3 encoded audio streams.
Windows Media Video
MPEG-2 is a container format, but there is also a codec of the same name, which most people call h. Once it was realized that the Internet was a delivery vehicle for things like video, people started decodre to come up with ways to share video that wouldn’t take up a lot of bandwidth and disk space. One of the big advances was the idea of streaming video — where your computer downloads only a part of a video and begins to play while the download continues — this means you don’t have to wait two hours for a movie to download before you can start watching.
Over the years the WMV format has grown to include support for high eecoder and video. To make things complicated, files that end in. Not only do you decodre to call the MPEG-2 compression codec h. One of the very nice things about h.
This is a very common codec for camcorders and digital video cameras. While there isn’t one “best video format,” there are best video formats for particular jobs. Things to be aware of when choosing a video format, apart from the intended audience — Will they be watching video streaming over the Internet? Do they have a fast connection? Do they have a DVD player? Do they have a Blu-ray player? For a number of years now, a good bet for a forward-looking, high-quality, versatile video format is h.
Performance of the two codecs is very similar. Adoptions and usage will determine if there’s an eventual winner. It’s relatively easy to convert between most non-DRM copy protected video formats with any number of free or low-cost conversion utilities found on the web.
If you do transfer between formats, remember that re-compression causes degradation, if quality is of paramount importance, don’t delete the originals, archive them somewhere.
Also keep in mind that when moving between containers some data streams such as decodef and 1080pp data can be lost if the new container doesn’t support them. As viewing experiences and platforms evolve, the way in which moving pictures are delivered will continue to evolve and change.
New containers and codecs will continue to be produced that will allow for larger amounts of data to be delivered more quickly and with additional data streams. Good organizational skills and regular migrating to new formats will make sure that your video survives as technology changes.

This is a great vidoe ,very informative, thank you. We are setting up live stream for our church. We actually switched from windows to mac. I would like to know which camcorder or professional camera under dollars that can do the job. Videeo have an old. Its only MB so I thought I would avoid compressing it altogether in order to keep the ‘quality’ some of the video is over 10 years old.
However, it does not play on any media device I have got but will play on my PC. The biggest compressed version i have got is a. Any ideas why it would not work? As you say above it only needs to be compressed to share and the media device holds much more than MB so whats the issue? It is also worthy of noting that not all stand-alone devices DVD players, television sets etc. As in — even if the video playback is choppy beyond reason, this is still the user’s fi,etype.

It’s up to them to lower the quality or find a lower-quality fileor upgrade their machine. Not so with stand-alone players! These devices usually can’t be upgraded, dexoder certainly their hardware can NOT be refreshed, except by buying an entirely new unit.
They don’t have the kind of structure a PC does. Instead, all decoding is done in specialized chips that do nothing else.
