AVI to MPEG-1: Convert Video from AVI(Audio Video Interleaved) to MPEG-1(MPEG-1 Video) with River Past Video Cleaner, AVI2MPEG-1 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 MPEG-1?

The first MPEG format for compressed video, optimised for CD-ROM. MPEG-1 was designed for the transmission rates of about 1.5 Mbps achievable with Video-CD and CD-i. Its compression algorithms allow better than VHS quality video and almost CD quality audio to be compressed onto and streamed off a single speed (1x) CD-ROM drive. MPEG encoding can introduce blockiness, colour bleed and shimmering effects on video and lack of detail and quantisation effects on audio. The official name of MPEG-1 is International Standard IS-11172.

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

To encode MPEG-1 video, you will need River Past MPEG-2 Booster Pack in addition to your video software.
