Summary

Export video frames as an image sequence using FFmpeg.wasm.

Inputs

  • binaryPropertyName — Name of the binary property containing the input video file. Default: 'data'.
  • outputBinaryPropertyName — Name of the binary property to store each exported frame. Default: 'data'.
  • sequenceOutputFormat (required) — Output image format for exported frames. Options: PNG, JPEG, WebP. Default: 'jpg'.
  • sequenceWidth — Output width in pixels. Use -1 to retain original width.
  • sequenceHeight — Output height in pixels. Use -1 to retain original height.
  • sequenceFps — Extract one frame every N seconds. fps=1 means 1 frame per second. Default: 1.
  • sequenceStartTime — Start time for frame extraction (HH:MM:SS or seconds). Default: '00:00:00'.
  • sequenceDuration — Duration of frame extraction in seconds. Leave empty to extract from start time to video end.
  • sequenceQuality — JPEG/WebP quality (1-100). Applied via FFmpeg -q:v. Default: 90.
  • additionalOptions — Optional collection for timeout, enableLogging, and encodingPreset.

Output shape

An array of items, one per extracted frame. Each item contains:

json: original item JSON augmented with ffmpeg metadata (operation, inputFilename, outputFilename as frame name, frameIndex, size in bytes). binary: outputBinaryPropertyName key mapped to { data: base64-encoded image, fileName: frame_XXXX.ext, mimeType: image/... }.

Examples

Example 1: Extract first 5 seconds of a video as JPEG frames at 1 fps, starting from 00:00:10.

binaryPropertyName: 'data'; outputBinaryPropertyName: 'frameData'; sequenceOutputFormat: 'jpg'; sequenceWidth: -1; sequenceHeight: -1; sequenceFps: 1; sequenceStartTime: '00:00:10'; sequenceDuration: '5'; sequenceQuality: 90
