Video Work subtitle extraction
Run lightflow.video_work_subtitles to request timestamped subtitle extraction
from the authenticated Video Work API MCP service. Provide one non-empty
video_path accepted by the API service sandbox. Consume the workflow's
subtitles output as the unwrapped service payload: it contains segments
(array), srt (string), and words (array). Do not invent transcript timing.
Configure LIGHTFLOW_VIDEO_WORK_API_URL and either
LIGHTFLOW_VIDEO_WORK_API_TOKEN or LIGHTFLOW_VIDEO_WORK_API_TOKEN_FILE only
in the workflow runtime environment. A non-empty token environment value takes
precedence; otherwise the file must be a regular UTF-8 file no larger than 4
KiB with non-empty trimmed contents. Never place or print the URL, token, token
file path, or file contents in workflow inputs, artifacts, source files,
prompts, logs, or command output. Require an HTTPS endpoint unless it targets
loopback.
Treat service errors, a missing MCP result object, or an invalid subtitle
payload schema as a failed extraction. Do not substitute a local ASR path or
bypass the Video Work API sandbox.
