Information on formats

AVI

AVI (Audio Video Interleave) is one of the oldest and most recognized video container formats, originally developed by Microsoft in 1992. Designed to synchronize audio and video playback, AVI became a standard format for digital video on Windows computers and is still widely supported by media players and editing software.

AVI can store video encoded with many different codecs, including DivX, Xvid, MPEG-4 and uncompressed video, as well as multiple audio formats. While it offers excellent video quality, AVI files are often significantly larger than modern formats because they lack today's advanced compression technologies.

Many users convert AVI files to MP4 or MOV to reduce file size, improve compatibility with mobile devices and simplify online sharing. VideoEnds allows you to convert AVI videos quickly while preserving the best possible quality.

MP4

MP4 (MPEG-4 Part 14) is the world's most widely used video container format. It combines excellent video quality with efficient compression, making it the preferred choice for streaming platforms, social media, mobile devices and web browsers.

MP4 supports modern codecs such as H.264, H.265 (HEVC) and AV1, together with popular audio formats including AAC and AC-3. Thanks to its broad compatibility, MP4 files can be played on almost every operating system, smart TV, smartphone and media player without additional software.

If you are looking for the best balance between compatibility, quality and file size, MP4 is usually the recommended output format for everyday use, online sharing and video publishing.
