# Video Compatibility Transcoder

Inspect a supplied video and transcode it to a broadly compatible H.264 and AAC MP4.

## Required Aident Actions

- <action-tag>cli:ffmpeg:inspect_media</action-tag> (required inputs: inputUrl): Inspect a media file and return its container and stream details in stderr.
- <action-tag>cli:ffmpeg:transcode_mp4</action-tag> (required inputs: inputUrl): Transcode a video to a broadly compatible H.264 and AAC MP4 asset.

Use Aident Loadout to read the current Action schema before constructing inputs. Check the required integration connection in Aident Vault. If an Action is billable or mutating, run Aident preflight, show the affected target and quoted cost or risk, and wait for explicit user confirmation before execution.

## Workflow

1. Confirm the requested outcome, source material, destination, audience, constraints, and acceptance criteria.
2. Apply the source-derived guidance below to create a concrete plan. Resolve ambiguity before invoking an Action.
3. Select only the Aident Actions whose documented effect directly advances the requested outcome. Do not invoke every listed Action by default.
4. Inspect the current schema and prepare the minimum valid input for each selected Action.
5. Preflight each selected Action. Execute it only after any required confirmation, in dependency order, and carry returned IDs or asset URLs into later steps.
6. Verify the returned IDs, URLs, statuses, or artifacts against the acceptance criteria. Report partial completion precisely and do not repeat paid or mutating calls blindly.

## Source-Derived Guidance

- Collect an Aident-accessible video asset, target playback environment, maximum dimensions, and any file-size or duration constraint; do not use caller-local filesystem paths.
- Use cli:ffmpeg:inspect_media to read the source container, streams, codecs, dimensions, frame rate, duration, and audio properties.
- Use cli:ffmpeg:transcode_mp4 only when the inspection shows conversion is needed, preserving aspect ratio and using the minimum settings required for an H.264 video and AAC audio MP4.
- Inspect the output and verify codec compatibility, dimensions, duration, audio presence, and successful playback before returning the output asset reference.

## Execution Boundaries

- Treat upstream provider-specific commands as background knowledge only. Execute the workflow through the exact Aident Actions above.
- Never request raw credentials in chat. Use Aident Vault connection flows for required accounts.
- Preserve user-provided wording, brand constraints, rights restrictions, and target identifiers. Do not invent authorization.
- Pass assets by Aident asset ID or supported URL fields. Do not expose caller-local filesystem paths to hosted Actions.
- Stop when a required integration is disconnected, preflight rejects the input, the target is ambiguous, or the user declines a required confirmation.

## Output

Return the execution plan, selected Action names, confirmed targets, Aident result identifiers or asset URLs, verification evidence, and any remaining blocked step.
