An “AMC file” is not restricted to one format 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.
The quickest approach is testing with VLC; if it plays, great, and if it doesn’t, converting to MP4 is the reliable fallback, 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” commonly maps to three possible types, which you can identify by noting where it came from, how large it is, and what it shows in a simple text editor, with the most widespread being a legacy mobile video format from older phone systems—megabyte-sized, often pulled from MMS, Bluetooth transfers, or old camera folders, appearing as binary garbage in Notepad—and the easiest test is VLC playback: if it works, it’s the mobile-video variant, and if not, converting to MP4 is often the safest bet because modern players may reject its container or 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 check if your AMC file is a video, rely on three fast indicators: where it came from, how big it is, and whether a player can open it, as AMC files appearing in old phone backups, MMS/Bluetooth folders, or DCIM/media paths almost always signal legacy mobile video, and files measured in megabytes align with video far more than the tiny mocap or macro/config types.
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.
