AVI video format

AVI, a short for Audio Video Interleave, is a file format designed to store both audio and video data in a standard package to allow its simultaneous playback. Created by Microsoft in November 1992, AVI is one of the most commonly used video formats. A variation of the AVI format, called DV AVI, is used to create Digital Video that can be transferred losslessly (without loss of quality) between computers and camcorders.

With Movavi Video Converter, you can convert AVI files to MPEG (DVD, VCD, SVCD), WMV, WAV, MP3 formats. Or you can convert MPEG, WMV, MOV, ASF format files to AVI format. You can use Movavi Video Converter as AVI Player as well.

AVI is a file format, but unlike other formats like MP3 or JPEG, AVI is a container format, meaning it can contain video audio compressed using many different combinations of codecs. So while MP3 and JPG can only contain a certain kind of compression, an AVI file can be compressed by all the following codecs:

AVI all look the same on the "outside", but on the "inside", they may be completely different.

So, the AVI format is dependent upon "codecs" (an acronym for compressor / decompressor). Codecs serve two purposes: they tell your computer how to encode (or compress) a video file when you save the file, and they tell your computer how to decode (or play) the file when you open the file. Since the same codec is used for both compressing and playing the file, the choice of which codec to use is extremely important. If the codec you use to compress your file is not installed on your user's computer, your user will not be able to play the video.

Using Movavi Video Converter as AVI player you will be offered to download and install an appropriate codec from our site if one is not already installed. However, you should not count on this feature, since downloads can be time consuming, and an appropriate codec cannot always be located.

Settings

• Specify a video codec to compress your file with. The drop-down menu shows the codecs correctly installed on your computer. You can download more codecs at Movavi website. For some codecs, you can specify its options (such as compression quality, bitrate mode and others) by clicking Options. If you choose Full Uncompressed, no codec will be used. This option provides best quality but largest file size. Select Recompress to save your file using selected codec and discard the orignial compression.
• If needed, enter new values for Width and Height of your video. The dimensions are in pixels. Check Link of width and weight to constrain the proportions. Chose Resize method and Resize quality.
• If needed, enter a new value for Frame rate. Larger values produce "softer" videos but require more system resources.
• Specify settings for the audio stream. Choose Audio format, sample rate and Channels (Mono or Stereo).
