Compress AVI for YouTube Shorts
Compressing AVI for YouTube Shorts comes down to three constraints: YouTube Shorts's 4 GB cap, its 1080:1920 resolution ceiling, and the need to output MP4 H.264 for reliable inline playback. AVI source files are typically 720p/1080p screen recordings at around 180 MB per minute — right at YouTube Shorts's 500 MB target. We calculate a per-clip bitrate budget from your duration, subtract 192 kbps for audio, and allocate the remainder to H.264 video at the highest quality that fits. AVI's legacy DivX/XviD/VC-1 codecs get transcoded to modern H.264 — typically a quality improvement at matched bitrate. YouTube Shorts does not play AVI inline, so this page does a format conversion (AVI → MP4 H.264) plus the size compression in a single pass.

How to compress AVI for YouTube Shorts
- 1Drag your .avi file onto the upload zone above (or browse to it).
- 2YouTube Shorts is already selected — we'll target 500 MB to stay safely under the 4 GB cap.
- 3Optionally trim to a highlight clip or switch to H.265 for 30-50% smaller files at the same quality.
- 4Download the compressed MP4 and share it on YouTube Shorts. Source file auto-deletes from our servers after 1 hour.
What to know about AVI → YouTube Shorts
- AVI's legacy DivX/XviD/VC-1 codecs get transcoded to modern H.264 — typically a quality improvement at matched bitrate.
- Resolution is kept at up to 1920p when the bitrate budget allows.
- Trim to the highlight before you compress — every 10 seconds you cut gives remaining frames more bitrate to work with.
- YouTube Shorts's 500 MB target leaves a 5% safety margin below its 4 GB hard cap, so platform-side rejection is never an issue.
The compression math
A 1-minute AVI at 720p/1080p screen recordings = ~180 MB. YouTube Shorts's 500 MB target minus 192 kbps audio = ~69713 kbps video budget. H.264 at that budget kept at up to 1920p when the bitrate budget allows produces a file at the target size that plays inline on YouTube Shorts.
About AVI files
AVI (Audio Video Interleave) is a legacy Microsoft video format from the 1990s, still commonly produced by screen recording software, older camcorders, and some Windows applications. AVI files are typically 3 to 5 times larger than modern MP4 files at the same quality because they use older, less efficient compression (or no compression at all). CompressYourVideo.com converts your AVI to a compressed MP4 with H.264 encoding, dramatically reducing file size while maintaining visual quality. A 500MB AVI screen recording might compress to 50MB as an MP4. The compressed output is compatible with every modern platform, unlike AVI which most social media sites and mobile devices refuse to play.
