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being an old mobile multimedia format created for early phones, holding low-resolution audio/video streams using outdated codecs that many modern players can’t decode, typically a few MB in size and originating from phone backups, MMS folders, or Bluetooth transfers, showing only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.
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” generally belongs to one of three groups, 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 meaning is Acclaim Motion Capture used in animation workflows, containing motion information rather than video—typically lightweight, frequently accompanied by an .ASF skeleton, and showing formatted numeric data when opened, which clearly marks it as mocap, while the third meaning comes from niche automation tools that store macros or project configs, with files that are small and contain readable XML/JSON-style structures or command sequences, so the rule of thumb is: large media-sourced files equal legacy video, .ASF plus readable motion data equals mocap, and small structured text equals a program-specific macro/config.
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.

A quick way to judge the file is by opening it in Notepad—true video containers usually show immediate binary gibberish instead of tidy text or numeric structure, and the clearest confirmation comes from VLC: successful playback means it’s video, while an error could indicate unsupported codecs or a non-video AMC, making a converter or FFmpeg the logical next step to check for recognizable audio/video streams and convert to MP4.
