Part 3. Overview of the Different Video File Formats

To deal with conversion and standard issues of videos, you must understand the different available video formats. The following are some of the commonly available variants, along with a brief detail about them. It will help you to gain a broader view of different video formats.

What’s MOV?

Mov is a MPEG-4 codec based video format developed by Apple in 1998. The video format works on both Windows and Mac operating systems, allowing the user to store multiple tracks in the same video. It is the first preference for storing movies as they contain several tracks with different data types.

Playing videos with this format will need you to have a specific codec based player on your system. Most common media players like VLC and Quick time support this format. These players can also convert MOV to MP4 without any problem. In case you get any trouble, try converting MOV to AVI and then into MP4.

What’s WEBM?

WEBM is a website specific audio-visual format. It works on a VP8 and OGG Vorbis technology that enables you to compress the video before uploading them on the web. It is an alternative of the MPEGA4 and h.264 standards, which is available for both commercial and non-commercial uses.

Most of the browsers and media players, including VLC, Opera, Chrome, Quicktime, and Firefox, support this format. Almost all these browsers allow you to convert WEBM to MP4 formats.

What’s MKV?

MKV, known as the Matroska Video File, is a format that came to light in 2002. This format enables the video creators to contain video audio as well as the subtitles into a single file. The file format can even work with elements that are entirely diverse from each other. For instance, you can use it for a combo of H.264 and MP3 file.

The benefits of this format include:

This future format of ready architecture also makes it flexible for conversions. Most of the media players, including VLC and Quicktime and iMovie, can run and convert MKV to MP4 format.

What’s GIF?

The Graphical Interchange format, more commonly known as GIF, is one of the most popular picture formats. It’s considered unique because this particular format supports a multi-frame structure that enables you to create motion images or animation. It doesn't have sound but supports multiple types of effects.

This multi-frame architecture also enables you to use it as a short video clip. Unfortunately, the format is quite outdated and a hybrid, so most new players cannot play it. Therefore, you will need to depend on a video conversion website or application to convert it. Most of the time, you can directly convert a GIF to MP4, but in some cases, you will need to convert GIF to Mp4 and then convert MOV to MP4 file.

What’s 3GP?

3GP is an audio and video multimedia format that saved the data using the 3rd generation partnership Project's video container. The video format is exclusively for 3G phones that transmitted and streamed data over 3G internet connections. Based on ISO media standard, it enables the user to store and stream multiple formats, including H.263, H.264, AMR-WB+, AAC-LC, and many more.

It also offered a wide range of compatibility with media players and worked perfectly with VideoLAN, Microsoft Movie and TV, Apple Quicktime, and many more players. The quality of 3GP videos is a bit lower than today's modern formats (full HD, 4K), but you can easily convert it into an MP4 file using the players playing it.

Here's the guide to repair corrupt 3GP files.

What’s FLV?

FLV is the common format for web-based applications like Adobe Flash and Adobe AIR. The video format also enhances audio-video synchronization, which is a great issue for online video streaming. Almost every website, including YouTube and Hulu that works with embedded videos, adopt FLV format.

Most players and devices will run this format without any issue, but if you face any, convert the video from FLV to MP4 format. You can use VLC, iMovie, as well as a conversion app or website for this task.

What’s AVI?

AVI or Audio-video Interleave is a standard video format for Windows devices. Microsoft developed it in 1992 for its OS, but later expanded it to other operating systems after a few years. The format can store both audio and video in high quality using multiple codecs like DivX and XviD. These codecs enable you to convert video without compression, preventing loss of quality over time.

However, due to lack or low compression, the file size may increase to a great extent. The file can work with all media players, including VLC and Windows media player, but it will be heavy to store. So, most users like to convert files from AVI to MP4 file before saving it. You can use a media player, website, as well as an application for this task.

What’s MP4?

The Motions Picture Experts Group created multimedia format-MP4 that is most common in the present world. Its container enables it to store both audio and video with adequate compression and very minor, almost no quality loss. Its quality makes it the first preference, a format that’s surpassing all the others.

As for its compatibility, every device and multimedia player, including VLC, QuickTime, and iMovie supports MP4 files. It also supports conversion into other formats, but you most probably won't need it.

What’s The Need Of Video Conversion?

All the video formats have their benefits and find their application, but at some point, you need to convert them into another format. Here's a list of a few reasons for this action.

Compress Videos

Every video format has its compression ratio. Some of them will take space in GB, while the same video in another format may take just a few MBs. Converting them will help you to choose the compression ratio and save space on your storage media.

Compatibility

Every player and application has a limitation on the video formats it can run. For instance, social media apps usually don't support GIFs (they are adding support for it). Similarly, Windows media player, the default player for Microsoft Windows doesn't support MKV. Video conversion helps you to turn the video into a format that you can run on your required player and application without any issue.

Transferring Video

In today’s high definition world, even a few minutes of video can acquire hundreds of MB in your system. The video may further reach to GB after editing though applications like Aftereffect. The high definition is good, but you cannot upload them over WhatsApp or Facebook. Transferring it over an online application is also troublesome. Therefore, you have to drop the resolution and the bitrate by a few percentages. Video conversion helps you in this process.
