An “AMC file” doesn’t have a single definition because extensions aren’t globally regulated, with the most familiar version being an old mobile multimedia format created for early phones, holding low-resolution audio/video streams using outdated codecs that many modern players can’t decode, typically a few MB in size and originating from phone backups, MMS folders, or Bluetooth transfers, showing only binary junk if opened in Notepad.
The easiest way to test an .amc file is simply opening it in VLC; if it works you’re set, and if not, converting it to MP4 is commonly the fix, with HandBrake working when it can detect the file and FFmpeg handling tough ones by transcoding to H.264/AAC, though another meaning is Acclaim Motion Capture used in mocap pipelines, which is plain motion data often paired with .asf and looks like numeric or structured text, and less commonly .amc may be a macro/config file for specialized automation tools containing things like XML or scripting lines, while the networking term “AMC” (Adaptive Modulation and Coding) has nothing to do with the .amc extension.
An “AMC file” usually fits into one of three categories, and you can tell which one you have by checking its origin, file size, and how it behaves in a basic text editor, with the most common version being an old mobile multimedia/video file from early phone ecosystems—usually a few megabytes, found in backups or MMS/Bluetooth folders, showing mostly unreadable binary in Notepad—and the quickest confirmation is to try VLC: if it plays, it’s likely the mobile-video type, and if not, converting to MP4 is the usual fix because modern players may not handle its container or codecs.

The second interpretation is Acclaim Motion Capture for 3D animation, which isn’t video at all but motion data—frequently small in size, often packaged with an .ASF skeleton, and displaying organized numeric text when viewed, making it easy to distinguish from binary media, while the third possibility is a macro/config/project file from a specialized automation app, which is usually small and contains readable XML/JSON-like settings or command lines, so in short: big and phone-origin suggests video, .ASF plus numeric motion text suggests mocap, and small structured text suggests 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.
