AVI to MP4/M4V: Convert Video from AVI(Audio Video Interleaved) to MP4/M4V(MPEG-4 Video) with River Past Video Cleaner, AVI2MP4/M4V converter, conversion

What is AVI?

Defined by Microsoft, AVI stands for Audio Video Interleave. It is a special case of the RIFF (Resource Interchange File Format). AVI is the most common format for audio/video data on the PC.

AVI is Microsoft's response to Apple's QuickTime technology. Early AVI files were limited on choice of video and audio codecs, quality, and resolution. However, with the introduction of DirectShow, AVI became a very flexible and powerful architecture. Some newer codecs including DivX and XviD enable AVI files to have similar or even better quality than DVD.

What is MP4/M4V?

A video compression standard planned for late 1998. MPEG-4 extends the earlier MPEG-1 and MPEG-2 algorithms with synthesis of speech and video, fractal compression, computer visualisation and artificial intelligence-based image processing techniques.

MPEG.ORG is an excellent source for additional information on MPEG format and usage.

To encode MP4 video, you will need River Past MPEG-4 Booster Pack in addition to your video software. Do not forget to have the latest QuickTime installed.

Additional Requirements

To convert from AVI(Audio Video Interleaved) to MP4/M4V(MPEG-4 Video) video with River Past Video Cleaner, you must have River Past MPEG-4 Booster Pack installed.

Add File

Click on the "Add File" button on the tool bar. The standard file open dialog appears. Select "AVI - Audio Video Interleave" in its "Files of type" combo box.

AVI is a file container format. It may use standard Windows codecs, or any of the third party codecs. If it uses a third party audio codec, you need to have the codec installed on your system for River Past Audio Converter to decode the file.

If you get an error when adding an AVI file, please open it in Windows Media Player and see if you can play it with audio. If not, you must find out what audio compression is used in the file and download the codec.

If you cannot add the AVI file, it may contain video and audio which use codecs not installed on your system. You can verify that by playing the AVI in Windows Media Player.

If WMP cannot play the file, the codecs absent. You will need to find out which codecs are used to encode the AVI and install them.

Usually, you can install ffdShow, which is compatible with many video compression, including DivX and Xvid. For audio, you may need to install AC-3 Decoder Filter or CoreAAC.
