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 MovKit DVD Ripper Pro, you can convert dvd to AVI file.

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 may carry audio/visual data in almost any compression scheme, including:

• Full Frames (Uncompressed)
• Intel Real Time Video
• Indeo
• Cinepak
• Motion JPEG
• Editable MPEG
• VDOWave
• ClearVideo / RealVideo
• QPEG
• MPEG-4
• and others.

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 MovKit DVD Ripper Pro 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. Visit MovKit DVD Ripper Pro website.

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 MovKit DVD Ripper Pro 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. Check Biquadratic approximation resizing for more precize resizing method, resulting in the better picture quality.
• If needed, enter a new value for Frames per Second. Larger values produce "softer" videos but require more system resources.
• Specify settings for the audio stream. Choose Audio format, frequency and Channels (Mono or Stereo).
  Best audio quality (in terms of file size/quality) can be achieved by selecting MP3 320 Kbit, 44100 kHz, Stereo.
