An “AMC file” has multiple possible identities since extensions get recycled, and the most common example is a legacy phone video container designed for low bandwidth and small hardware, carrying old codecs that modern tools might not decode, usually a few MB and found in old phone backups or media directories, displaying as binary noise in editors like Notepad.

Trying VLC is the simplest test; if playback works you’re finished, and if not, MP4 conversion is the common fix, with HandBrake helping when it detects the file and FFmpeg succeeding by transcoding to H.264/AAC, but .amc might instead be Acclaim Motion Capture motion data—paired with .asf and appearing as structured text—or a macro/config file for niche automation tools containing XML/JSON or command-like entries, and it shouldn’t be mixed up with the unrelated networking concept AMC.

An “AMC file” tends to be one of three possibilities, which you can spot by checking its source, its size, and whether a text editor shows gibberish, with the typical case being a legacy mobile multimedia format from older phones—megabytes in size, found in backups or MMS/Bluetooth/media folders, and full of unreadable binary in Notepad—and VLC is the quick test: if it plays, it’s the mobile-video form; if not, converting to MP4 is the go-to solution due to outdated containers/codecs.

The second common meaning is Acclaim Motion Capture used in 3D animation pipelines, where the .amc isn’t video but joint-motion data over time—typically much smaller than true media files, often arriving with a matching .ASF skeleton, and showing structured numeric text when opened, which strongly indicates mocap rather than multimedia, while the third meaning is a niche macro/config/project file from a specific automation tool that appears small and reveals readable XML/JSON-like settings or command lines, so in short: large files from old phone media suggest legacy video, files with .ASF nearby and readable numeric motion data indicate mocap, and small structured text points to an app-specific macro file.

To see if an AMC file is a video, consider its origin, its size, and whether playback software recognizes it, because files pulled from aged mobile backups, MMS or Bluetooth transfers, or DCIM/media directories strongly imply a mobile-era video format, and multi-megabyte sizes usually confirm video rather than lightweight mocap or macro/config files.

One easy check is viewing it in Notepad—if the file is a video container, you’ll see messy binary almost instantly rather than readable text or orderly numbers, and the definitive test is VLC: if VLC plays it, it’s video; if not, you may be dealing with unsupported codecs or an entirely different AMC format, so running it through a converter or FFmpeg is the usual way to see whether any audio/video streams can be detected and turned into MP4.
