"A few years ago, I digitized my entire Blu-ray collection so I could watch movies on an old DivX-certified TV in my parents' basement. That’s when I realized MP4 or MKV weren't always the best choice."

Many guides today recommend MP4 or MKV, and for most modern devices tha's true. But there are still situations where AVI is the smarter option:

  • Some older TVs, DVD players, or in-car entertainment systems only support AVI files with DivX/Xvid codecs.
  • When paired with the right settings, AVI with Xvid can offer decent quality for 1080p movies while saving space.
  • AVI is a lightweight container that works well if you don't need more than one audio track or fancy subtitle options.

FAQs

Is AVI better than MP4 for ripping Blu-rays?

For modern smartphones, tablets, and smart TVs, MP4 is the better choice due to its superior compression and widespread compatibility. However, AVI is the better and sometimes the only option if you need to play ripped Blu-ray movies on legacy hardware, such as older DVD players, standard-definition TVs, or specific in-car entertainment systems that strictly rely on DivX/Xvid codecs.

How large is an AVI file ripped from a Blu-ray disc?

A raw Blu-ray movie can take up 25GB to 50GB of space. When converted to an AVI file with Xvid compression at 1080p resolution, the final file size ranges from 2GB to 5GB, depending on the movie's length and the bitrate you choose. You can adjust the video parameters in the advanced settings to further compress the file size if your storage is limited.

Conclusion

While converting Blu-ray to AVI might seem like a niche requirement in the streaming era, it remains a practical way to keep your physical media accessible on the devices you already own. You don't need to throw away an old home theater system or a perfectly working car DVD player just because of format incompatibility.
