FAQs

Why would anyone still need AVI in 2026?

A surprising range of devices only accept AVI: older car head units, some DVD players, USB playback on legacy TVs, and certain industrial/medical equipment — that's the real demand behind this conversion.

Will the AVI file be large?

Yes. AVI is an inefficient container — expect notably bigger files than MP4 at the same quality. The "Low" quality preset helps keep size down.

Can H.265 video go straight into AVI?

Not directly — the tool automatically falls back to H.264 (which AVI handles reliably) and raises the bitrate to preserve quality. No manual juggling needed.
