Old AVI files won’t play on a new TV?

XviD/DivX was the format of the 2000s. Newer TVs and boxes often drop it — convert to H.264 MP4, which plays everywhere.

Your files stay on your device. Nothing is uploaded.

1 Your TV, box or projector

Not on the list? Paste the “supported formats” table from the manual

2 Your videos

Drop videos or a whole folder here Series, films, home videos — any number, any size. .srt files with the same name are picked up as subtitles.

3 USB stick, sound and subtitles

Fit everything on a stick of Stick format Split files over 4 GB into parts instead of shrinking them Picture quality Tidy up: “Show/Season 01/Show S01E02”, safe file names

Audio language (first available wins) Sound Night mode: quiet dialogue louder, explosions softer Same loudness for every episode (EBU R128) Subtitles

4 Save to the stick or a folder

Long batch? Leave the tab open and visible — the screen is kept awake. If the tab is closed, open the page again and press “Continue”: finished files are skipped.

Why AVI is a problem

Samsung TVs since 2018 are widely reported not to play DivX/XviD, even though their spec sheets still list MPEG-4 ASP; many boxes and projectors only play H.264. Old AVIs also often carry MP3 or AC3 sound that some devices refuse inside AVI.

How CompressLab converts AVI

Browsers can’t read AVI or decode XviD, so these files go through a WebAssembly build of FFmpeg on your computer: roughly 2–3× real time for SD video. The result is H.264 + AAC in MP4.

Going the other way: DVD players with USB

DVD/DivX players read only XviD AVI up to 720×576 with MP3 sound from FAT32 sticks. Choose “DVD / DivX player” as the device and CompressLab makes exactly that.

Questions

How long does it take?

About a third to half of the running time for SD AVIs on a typical laptop — leave a batch running overnight.
