The AVI file format is one of the most widely used multimedia containers ever devised. AVI, which stands for audio video interleaved, was first introduced to the public by Microsoft in 1992 as part of their 'video for windows' multimedia framework. Being a container format, an AVI file with the .avi filename extension can exist with both video and audio content synchronized for playback. The format can thus be used by authors to edit and encode audio video sequences or just video sequences. The Digital video AVI format exists in two forms, Type 1 and Type 2.
The .asf filename extension refers to the Microsoft owned audio and digital video container, advanced systems format. It is a container for windows media audio and windows media video but shares the same internal structure as both WMA and WMV file formats. The format was designed with the goal of increasing efficiency in distribution of audio video files across computer networks. However, it works just as well for local system playback. The asf format forms part of Microsoft's Foundation framework. The major feature of the format is its ability to add digital rights management by providing the framework for encrypting audio and video files.
FreeFileConvert uses tuned encoding for AVI to ASF conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload AVI files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized ASF results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent ASF audio with dependable progress tracking.
The AVI format was derived from the RIFF or resource interchange file format which is a generic container format. Digital video that is interleaved can be stored natively as a single stream conforming to the type-1 specification of the AVI file format. This has the disadvantage however of not being compatible with the video for windows framework. In general, the number of blocks in .avi files determine the amount of overhead. Overhead associated with the audio stream is determined by which codec is used to encode the stream for example AC3 or MP3-VBR.
An ASF file can wrap bit streams formed from various formats such as binary, JPEG still images, script commands, video, and audio. However it is principally used as a wrapper for audio and video files specifically WMA and WMV. The ASF format includes support for metadata including content descriptors, and information for DRM use. Content Encryption is also supported requiring the use of a license key before the asf file can be played.
