Turn a media-size audit into a GPU transcoding setup

Why use this

1. A media-library owner may see unusually large files without knowing whether re-encoding would preserve the streams, quality and playback features they need. A storage-saving setup can become destructive if it overwrites originals before compatibility is checked.

2. A candidate audit and isolated configuration plan could show which files merit a small review trial and which settings remain uncertain. The owner could evaluate preservation requirements before enabling any automated transcoding.

Why an agent / simpler alternative

Useful judgment

Connect file-size outliers with media characteristics and identify preservation-sensitive exceptions.

Simpler alternative

Use manual encoding presets for a small number of known files.

Unsuitable when

Originals cannot be retained or required quality and playback constraints are undefined.

Proposed inputs

1. Name

   Media inventory sample

   Owner

   Library owner

   Minimum scope

   Selected file sizes, formats and stream metadata

   Quality check

   Identify subtitles, audio tracks and originals that must be preserved.

2. Name

   Host and quality constraints

   Owner

   System owner

   Minimum scope

   Redacted hardware/configuration details and acceptable output requirements

   Quality check

   Confirm available storage for reversible trials.

Access and setup — proposed or unknown

Proposed minimum

1. Read-only inventory and an offline configuration proposal; no service installation or encoding.

Compatibility unknowns

1. Unknown: exact runtime, GPU/driver support, container compatibility and codec behavior.

External actions requiring approval

1. Installing services, changing Compose files, allocating resources or replacing/deleting media.

Expected deliverable and review checks

Proposed artifact

Size-outlier assessment and proposed isolated transcoding configuration with preservation checks.

Critical checks

1. Required streams and original files remain accounted for.

2. Predicted savings and performance are labelled unmeasured until a separate authorized trial.

Missing output evidence

No new workflow run or output inspection is performed for this editorial layer. The linked implementation evidence retains the original source-specific outcome and artifact limits.

Failure signals and proposed responses

1. Signal

   The proposed preset drops a subtitle or alternate audio stream.

   Why it matters

   The output may lose needed content despite looking smaller.

   Proposed response

   Hold the preset and require explicit stream-preservation review.

2. Signal

   Automated output replaces the only original.

   Why it matters

   A poor encode could be difficult to reverse.

   Proposed response

   Use a separate destination and retain originals before considering replacement.

Effort and cost — unknown

Setup work

1. Define preservation criteria and a reversible trial layout.

Ongoing review

1. Inspect playback and resource behavior after authorized experiments.

Unknowns

1. Unknown: power use, processing time, quality loss and actual storage savings.

First check — proposed, unexecuted

Status

proposed_unexecuted

Synthetic fixture

Invented media metadata includes multiple audio tracks and a subtitle stream absent from a proposed preset.

Acceptance checks

1. The preservation mismatch blocks progression.

2. No encoding or deletion is represented as completed.

Stop conditions

1. Installation, live resource changes or irreversible replacement is required.

Limits

1. Editorial storage-planning aid; no GPU compatibility, output quality or savings is established.
