| Description | 🔵 Honestly, AVI is a bit of a relic. Microsoft pushed it out in '92, and while it was a big deal then, it's basically the 'grandfather' of video containers now. It doesn't actually do any of the encoding itself; it’s just a digital wrapper meant to keep audio and video from drifting apart. The quality is totally dependent on whatever codec you've stuffed inside—use a good one and it’s fine, use a bad one and you’re stuck with a 'crunchy' video that’s somehow still a massive file. |
| Technical details | 🔵 The real technical headache with AVI is that it’s just too simple. It’s a very linear structure that usually only juggles two streams. Unlike modern formats like MPEG or MOV, it doesn't have any of those 'smart' metadata tricks or predictive compression logic. It’s a 'hands-off' format, meaning it leans entirely on external codecs to handle the dirty work. You’re constantly stuck in a balancing act: go lossless and you'll watch your hard drive space vanish in minutes, or go lossy and pray the artifacts don't ruin the shot. To be blunt, it’s a dinosaur. Because it lacks the efficiency of modern containers, the files are almost always way bulkier than they have any right to be. It’s a reliable old workhorse for legacy systems, but in 2026, it’s mostly just a storage-hogging reminder of how far we’ve come. |
