An “AMC file” can belong to different software systems since extensions get reused, but the common one most users see is a legacy mobile video container from older phones that stored low-resolution audio and video optimized for limited bandwidth and small hardware, which modern players may struggle with due to obsolete codecs, and these files often show up as small megabyte-sized items in phone backups or MMS/Bluetooth directories and appear unreadable when opened in plain-text editors.

The quickest approach is testing with VLC; if it plays, great, and if it doesn’t, converting to MP4 is the typical fix, using HandBrake when it recognizes the file or FFmpeg to re-encode as H.264/AAC when others fail, though .amc also appears as Acclaim Motion Capture data used with an .asf skeleton and showing structured text rather than video, plus some niche automation tools use .amc for macro/config files that contain readable formats like XML or command lines, and none of this relates to the networking term AMC, which has no universal file counterpart.
An “AMC file” is often classified into three types, and you can identify which one by checking the source, size, and Notepad output, with the common version being a legacy phone-era multimedia/video file—usually a few megabytes, coming from MMS/media backups or Bluetooth transfers, and showing binary noise in Notepad—and VLC is the simple test: if it plays, that’s what it is; if it doesn’t, converting to MP4 is usually required because the original codecs may no longer be supported.
The second major meaning is Acclaim Motion Capture for 3D animation work, where an .amc contains movement data instead of video—usually smaller in size, often paired with an .ASF skeleton, and full of structured numeric text when viewed, which is a clear sign of mocap, while the third category is a macro/config/project file from a particular automation program that tends to be small and displays readable XML/JSON-like text or command lines, so the quick rule is: big media-origin files imply old mobile video, mocap bundles with .ASF imply animation data, and small structured text suggests a program-specific macro.
To determine whether your AMC file is a video, pay attention to its source location, its file size, and how media software reacts to it, because files originating from old handset backups, MMS/media retrievals, Bluetooth transfers, or DCIM-style folders strongly indicate the phone-era video variant, and multi-megabyte sizes are another strong hint compared to the much smaller motion-capture 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.
