How to trim a video with Medux MCP

Codex prompt pattern

In this workspace, use medux_trim_video through Medux MCP to trim a video.
First inspect and identify the source video and exact start and end times.
Show me the exact tool arguments before execution.
After the task completes, return the trimmed video and verify that the output begins and ends at the requested times and remains playable.

Approval gate

Before approving the call, compare the selected tool, file or asset IDs, ordering, timing, and output settings with the request. If a local filename was mapped to an uploaded Medux file ID, keep that mapping visible so it can be audited later.

Result verification

Let Codex monitor an asynchronous task until it reaches a terminal state, then save or report the trimmed video. The final check is explicit: confirm that the output begins and ends at the requested times and remains playable.

Claude prompt pattern

Using the assets and requirements in this conversation, help me trim a video with Medux MCP.
Restate which input fulfills each role: the source video and exact start and end times.
Propose the medux_trim_video call and summarize its arguments before asking for approval.
When it finishes, return the trimmed video with a checklist confirming that the output begins and ends at the requested times and remains playable.

Context checkpoint

Have Claude summarize the intended transformation, identify every source asset by role, and list the important constraints. Review that summary together with the proposed tool arguments; correct the conversation first if a file, order, time range, or setting is ambiguous.

Result verification

Keep the Medux task ID in the conversation while Claude checks progress. When processing ends, ask for the trimmed video plus a concise validation checklist confirming that the output begins and ends at the requested times and remains playable.
