AVI Video Format

AVI Converter

AVI is a common type of video file, which Microsoft developed for Windows and launched in 1992. AVI is short for Audio Video Interleave, and like many other video formats, AVI files are container files that include both video and audio in different codecs. AVI files are compressed but to a lesser extent than some other video formats; this means they tend to have higher quality video but may also have a larger file size.

Although MP4 is probably the most common video format and an ISO standard, AVI files are also widely supported and can be played by numerous media players, including Windows Media Player, QuickTime, VLC and MPlayer. If you are having problems playing an AVI file, you may need to convert it to another format like MP4 first, or you may be able to play it by first installing an additional codec for your media player. AVI is one of the formats that can be used to upload videos to YouTube or Vimeo, and social media sites like TikTok, Instagram and Facebook also support AVI videos.

MP4 Video Format

MP4 Converter

MP4, sometimes called MPEG4, is one of the most common video formats. MP4 was developed to be easily played and shared. It was originally developed by the Moving Picture Experts Group (MPEG) but has become an ISO standard, meaning that it’s now maintained by the International Organisation for Standardization. As MP4 is a standardised format, it will normally play easily on most devices and media players, including Windows Media Player, QuickTime, and VLC. MP4 is usually the preferred format for uploading videos to YouTube, Vimeo or other websites.

MP4 videos are made up of video and audio elements that are compressed separately. The video part is usually compressed with MPEG-4, and the audio is usually compressed using AAC, which is the audio format associated with iTunes. Because both file elements are compressed, MP4s normally have a smaller file size than many other video formats, but still maintain relatively high quality for sharing online.

Zamzar’s tool is also useful if you want to convert multiple AVI files in one go.

If you’re looking for higher resolution, AVI is a good option. However, the higher quality means the file sizes tend to be much larger, meaning you may need to compress your AVI file if you want to share it or store it on your device. For this reason, some people feel MP4 is a better choice - files tend to have a smaller file size and they can be played with most media players, including those on Apple devices. If you want to convert an AVI file to MP4 format, then the online conversion tool on Zamzar’s website makes this really easy.

On a Mac you can convert AVI to MP4 using QuickTime. Open the application, click the ‘File’ menu and add your AVI file. Once uploaded, click the ‘File’ menu again, select ‘Export’, then choose MP4 as the format you’d like to export the file to. Click ‘Save’, and the file will be converted to MP4. If you’d prefer to use a simpler online conversion solution, Zamzar’s free service works just as well with fewer clicks. It’s also more convenient if you want to convert multiple files.
