Choose an output format
Compare video, PNG frames, spritesheet metadata, and engine packages, including transparency and entitlement requirements.

Start with the destination
For a quick inspection, download PNG frames ZIP. For a custom runtime, use a spritesheet and its matching JSON. For an engine import, choose the package for that engine and read the included instructions.
The Web export dialog initially selects PNG frames ZIP. The one-click Public API defaults to spritesheet when output_formats is omitted. Specify formats explicitly if a pipeline depends on a particular artifact.
Format guide
| API format | What you receive | Typical use |
|---|---|---|
clip_video |
Selected MP4 clip; opaque | Review, ordinary video playback |
webm_alpha |
WebM with alpha | Compatible alpha-video players; test target support |
prores_4444 |
ProRes 4444 with alpha | Compositing and video editing |
frames_zip |
ZIP of PNG frames | Inspect individual frames or custom import |
spritesheet |
PNG texture atlas | A single packed texture |
spritesheet_json |
Matching frame metadata | Frame rectangles and timing |
unity_meta |
Unity texture metadata | Pair with the matching spritesheet |
unity_pack |
Unity-oriented ZIP | Atlas, metadata, JSON, manifest, instructions |
godot_pack |
Godot 4-oriented ZIP | SpriteFrames and AnimatedSprite2D resources |
unreal_paper2d_pack |
Unreal Paper2D-oriented ZIP | PNG atlas and Paper2D sprite description |
cocos_creator_pack |
Cocos Creator 3.x-oriented ZIP | PNG/PLIST atlas and example player |
Metadata formats are not standalone images. Request or keep the matching texture. Treat returned outputs as the actual artifact list rather than assuming one particular array position or extension.
Transparency is a source-and-format contract
Ordinary MP4 and the raw generated video remain opaque. Transparent PNGs, atlases, engine resources, WebM Alpha, and ProRes 4444 require appropriate source and export settings.
The Public API supports transparency only for Alpha Key sources. It does not remove arbitrary backgrounds. See transparent animation.
A player may ignore an alpha channel even when it exists in the file. Test in the target application; use PNG frames or a suitable editor to distinguish a display limitation from an export problem.
Import engine packages intact
Engine ZIPs include animgen-manifest.json and instructions. Keep their relative paths intact. Godot resources refer to their package paths; Unreal Paper2D import requires the relevant engine tooling.
Frame rectangles in the manifest use a top-left origin; normalized pivot coordinates use a bottom-left origin. Read the manifest rather than guessing from the texture dimensions. Verify frame order, timing, scale, pivot, and transparency in a small test scene before using the result throughout a project.
Credits, access, and downloads
Free web access includes PNG frames ZIP. Advanced formats require paid export entitlement; having credits and having a format entitlement are separate checks. See credits and access.
Files are exposed as assets with short-lived signed download links. Save the file, not the URL. API callers should follow polling and downloads.
Finish the import in your engine
Continue with Unity, Godot 4, Unreal Paper2D, or Cocos Creator 3. Each guide matches the actual package files, paths, and playback helpers; it does not imply every engine has been runtime-tested.
See canvas and pivot for placement and transparent format compatibility for video compositing.
