- Distinct from DeluxePaint Animation (Anim or ANM) files.
ANIM is an animated raster graphics format that was widely used on Amiga computers.
It uses the IFF container format. The first frame is usually (more or less) in the form of an embedded ILBM file. The other frames use one of a number of available schemes for storing the differences from a previous frame.

[edit] Frame operations
Each frame (except possibly the first frame) has an ANHD chunk with an "operation" field, which tells how that frame's pixel data is structured, compressed, etc. Usually, for a given ANIM file, all frames with a nonzero operation use the same operation.
Only operations 0, 5, and 7 are reasonably common.
Known operations:
| Operation | Name | Description | Remarks |
|---|---|---|---|
| 0 | direct ILBM | Frame uses the ILBM image format. The actual compression method (usually PackBits) is given by a field in the frame's BMHD chunk.
| |
| 1 | ANIM-1, ANIM1 | XOR ILBM | Rarely supported. |
| 2 | ANIM-2, ANIM2 | long delta | Rarely supported. |
| 3 | ANIM-3, ANIM3 | short delta | |
| 4 | ANIM-4, ANIM4 | generalized delta | Rarely supported. |
| 5 | ANIM-5, ANIM5 | byte vertical delta | The most common frame format. |
| 6 | ANIM-6, ANIM6 | stereo byte vertical delta | Rarely supported. |
| 7 | ANIM-7, ANIM7 | generalized vertical delta, separate data | |
| 8 | ANIM-8, ANIM8 | generalized vertical delta, inline data | |
| 74 | ANIM-J, ANIM-74 | Eric Graham's format. Used by Sculpt 3D, etc. More than a frame format, ANIM-J is an extension that supports more sophisticated playback. | |
| 100 | ANIM32 | long vertical | Reportedly used by Scala Multimedia/MM400 and InfoChannel/IC500. |
| 101 | ANIM16 | short vertical | Reportedly used by Scala Multimedia/MM400 and InfoChannel/IC500. |
| 108 | ANIM-l | (That's a lowercase L - ASCII 108.) Reportedly by Eric Graham. |
[edit] Audio
There are at least a couple of extensions that add audio to an ANIM file.
- .sndanim: Refer to AnimFX's documentation of the
SXHDandSBDYchunks. - An extension based on 8SVX.
[edit] Identification
Files begin with bytes 'F' 'O' 'R' 'M' ?? ?? ?? ?? 'A' 'N' 'I' 'M'.
