# FFprobe as Json Action

The **FFprobe as JSON Action** node can be used to obtain a complete asset analysis from FFprobe as a JSON response.

To use this node, an FFprobe binary must be available and its file path must be provided.

The JSON response can be retrieved either via the [{stream.last\_result}](https://docs.helmut.de/helmut4-releases/helmut4-components/streamdesigner/wildcards/result-or-return-wildcards-2/stream-last_result) wildcard or directly through [{node.result.?}](https://docs.helmut.de/helmut4-releases/helmut4-components/streamdesigner/wildcards/result-or-return-wildcards-2/node-result).
