AVB may indicate different things in different domains, and the .AVB extension most commonly corresponds to an Avid Bin used in Avid Media Composer to store project metadata including clips, subclips, sequences, and markers, with the actual media housed outside the bin in locations like `Avid MediaFiles\MXF`; bins must be opened within Avid, and if media appears offline it usually signals missing files, while non-Avid uses of “AVB” in networking or Android security don’t refer to openable files at all.

In pro A/V and certain automotive Ethernet environments, AVB refers to Audio Video Bridging, an IEEE framework ensuring synchronized, bandwidth-reserved media over Ethernet rather than defining a file format; in Android firmware work, AVB instead means Android Verified Boot, which validates partitions during startup using elements like `vbmeta`, and older software may also assign `.avb` to Microsoft Comic Chat Character files when not tied to Avid.

How an AVB file is opened depends on the specific meaning of AVB, but if it’s an Avid Bin (.avb), it must be opened inside Avid Media Composer by selecting the correct project and opening the bin there, after which items appear as Avid assets; Media Offline usually signals missing media rather than bin failure, so ensuring the `Avid MediaFiles\MXF` drive is available and running Relink often fixes it, and corrupted bins can often be restored using Avid Attic backups.

If your “AVB” is Audio Video Bridging from the networking world, you won’t have any AVB file to open, because AVB concerns timing/bandwidth on Ethernet rather than documents; if it’s Android Verified Boot, you interact with firmware and verification metadata (e.

An Avid Bin (`.avb`) never contains the real audio/video, and that’s the key idea: it’s a metadata container that records editorial decisions like which clips exist, what timecode ranges you used, how sequences are built, and what markers you added, while the real media lives separately in MXF folders such as `Avid MediaFiles\MXF\…`; copying only the `.avb` moves the “map” without the “territory,” so Avid can open the bin but will show Media Offline until the correct media is attached or relinked, and this design keeps bins light, easy to back up, and separate from heavy media—meaning an `.avb` alone won’t “play” unless the media or another export format accompanies it.
