An “AMC file” can mean different things due to extension reuse, though the version most users encounter is a legacy phone-era video container built for tiny screens and low processing power, often encoded with obsolete codecs that modern players may not support, commonly found as small megabyte files in old backups or media folders and appearing as messy binary data when viewed in Notepad.
Trying VLC is the simplest test; if playback works you’re finished, and if not, MP4 conversion is generally the best option, 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” 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 often necessary 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 tell whether your AMC file is a video, look at three quick clues—its origin, its size, and whether a media player can read it—with files from old phone backups, MMS/Bluetooth transfers, or legacy DCIM/media folders strongly suggesting the mobile-era video type, and sizes in the multi-megabyte range reinforcing that it’s video rather than the much smaller mocap or macro/config variants.
Opening the file in Notepad is a simple test—true video containers typically show chaotic binary from the start, not cleanly formatted text or structured numbers, and VLC is the surest confirmation: working playback signals video, while errors could point to old or unsupported codecs or a non-video AMC type, making a converter or FFmpeg the next logical step to inspect for audio/video streams and convert to MP4.
