An "AMC file" has several possible meanings 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 most straightforward check is opening the .amc in VLC; if it plays you’re done, and if it doesn’t, converting to MP4 is often the right move, with HandBrake working when it can read the file and FFmpeg stepping in by re-encoding to H.264/AAC for stubborn cases, though the extension may also refer to Acclaim Motion Capture motion data seen with an .asf skeleton and formatted as structured text, or less commonly to macro/config files for automation tools containing XML or simple scripting, and it’s entirely separate from the AMC networking term, which is not a file format.

An "AMC file" tends to appear in three major forms, 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 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 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.

A quick Notepad check helps—video-type AMC files nearly always display immediate unreadable binary rather than neat text or numerical formatting, and VLC provides the final word: if it plays, it’s definitely video; if VLC refuses, it might be an unsupported codec or a different AMC category, so trying a converter or FFmpeg is the usual follow-up to detect and re-encode any streams into MP4.
