Good to know

• AVI files almost always use older video and audio formats, so Flecto re-encodes them to H.264 and AAC. It uses your graphics card when it can and falls back to the processor.
• The MP4 is often much smaller than the AVI, because H.264 is far more efficient than the formats AVI files typically use.
• A re-encoded MP4 keeps the first video track and the first audio track. Extra audio tracks and subtitles are not carried over.
• Audio and video conversions use FFmpeg. Flecto offers to download it once, and after that it works offline.
• The free plan includes 10 conversions every week. Failed or cancelled files do not count.

Why move old AVI files to MP4

AVI is a Microsoft container from the early 1990s. Camcorders, capture cards and downloads used it for years, usually with DivX, Xvid or uncompressed video inside. Phones, smart TVs, browsers and current editing programs often refuse these files or play them without sound.

Converting an archive of family videos to MP4 makes them playable again and usually frees disk space. Re-encoding cannot add detail, so keep the original AVI of anything precious until you have checked the MP4.
