AVI at a glance
AVI
Convert to AVI when an older editor, recorder, analysis tool, or device workflow explicitly expects it, or when preserving compatibility with legacy video archives matters.
It is useful for certain capture and processing chains where AVI remains a known stable interchange wrapper.
For streaming, web playback, and compact delivery, MP4 or WebM are usually stronger options.
HEIF at a glance
HEIF
Convert to HEIF when the destination benefits from modern image containers that can preserve more than a single flat raster, such as advanced mobile-photo workflows or efficient high-quality storage.
It is a strong target in contemporary imaging ecosystems.

What should I review after converting AVI to HEIF?
Check the exported file for Tooling and compatibility are not as universal as the oldest web raster formats.; Interoperability depends on both the container profile and the encoded image data inside it..
