Codex-specific workflow

Run Remove a Watermark from Video as a Codex MCP task

Use the active workspace as the source of truth. Ask Codex to identify the source video and the watermark region or reference, select medux_video_remove_watermark, and keep the Medux task ID and returned output with the rest of the project. Naming the input roles and the expected result prevents an agent from guessing which file should be used where.

Codex prompt pattern

In this workspace, use medux_video_remove_watermark through Medux MCP to remove a watermark from a video.
First inspect and identify the source video and the watermark region or reference.
Show me the exact tool arguments before execution.
After the task completes, return the cleaned video and verify that the watermark is removed through the required frames without damaging unrelated regions.

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 cleaned video. The final check is explicit: confirm that the watermark is removed through the required frames without damaging unrelated regions.

What this tutorial does

Medux operation

Create a video processing task that removes a watermark from an uploaded video.

Agent workflow

Codex selects medux_video_remove_watermark, presents the arguments for review, calls Medux, and reports the response.

Before you start

Authentication

  • Authentication is required via Authorization header.

Preconditions

  • Requires a previously uploaded video asset.
  • Requires an existing video file id.

Prompt Codex

Start with a clear instruction that names the Medux operation and the intended inputs.

Remove the watermark from the uploaded source video {file id}. If the watermark area is known, pass region {x, y, width, height}.

Request fields to review

Confirm these values before approving the MCP tool call. The linked API page remains the source of truth for current limits and response semantics.

FieldTypeRequirementPurpose
file_idstringRequiredProvide the value described in the API reference.
region.heightint32OptionalProvide the value described in the API reference.
region.widthint32OptionalProvide the value described in the API reference.
region.xint32OptionalX coordinate of the region's top-left corner in pixels.
region.yint32OptionalY coordinate of the region's top-left corner in pixels.

Step-by-step workflow

01

Connect Medux MCP to Codex

Add the Medux remote MCP endpoint to Codex, provide an authorized credential, and confirm that the medux_video_remove_watermark tool is available.

02

Prepare the required inputs

Prepare the source files, asset IDs, text, or settings required by the operation. Upload local media first when the tool requests file IDs.

03

Ask Codex to run Create Video Watermark Removal

Use one direct instruction with the intended values. Codex should select the Medux tool and show the proposed arguments before execution.

04

Review and approve the tool call

Check that the tool is medux_video_remove_watermark and that each file ID, task ID, option, and output setting matches your request before approving it.

05

Check the Medux response

If Medux returns an asynchronous task, let the agent monitor it until completion; otherwise review the immediate response and save any result identifiers or output URLs.

Frequently asked questions

Can Codex use the Medux Create Video Watermark Removal API through MCP?

Codex can call the medux_video_remove_watermark Medux MCP tool to create a video processing task that removes a watermark from an uploaded video. This guide covers the required inputs, approval flow, result handling, and the matching API reference.

Which MCP tool does this tutorial use?

This workflow uses medux_video_remove_watermark. Review its arguments before approval and consult the API reference for the current contract.

Claude-specific workflow

Run Remove a Watermark from Video as a Claude MCP workflow

Keep the goal, source assets, and constraints together in the conversation. Ask Claude to restate the source video and the watermark region or reference before proposing medux_video_remove_watermark. That context checkpoint makes the file roles and desired outcome easy to correct before any Medux call is approved.

Claude prompt pattern

Using the assets and requirements in this conversation, help me remove a watermark from a video with Medux MCP.
Restate which input fulfills each role: the source video and the watermark region or reference.
Propose the medux_video_remove_watermark call and summarize its arguments before asking for approval.
When it finishes, return the cleaned video with a checklist confirming that the watermark is removed through the required frames without damaging unrelated regions.

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 cleaned video plus a concise validation checklist confirming that the watermark is removed through the required frames without damaging unrelated regions.

Frequently asked questions

Can Claude use the Medux Create Video Watermark Removal API through MCP?

Claude can call the medux_video_remove_watermark Medux MCP tool to create a video processing task that removes a watermark from an uploaded video. This guide covers the required inputs, approval flow, result handling, and the matching API reference.

Which MCP tool does this tutorial use?

This workflow uses medux_video_remove_watermark. Review its arguments before approval and consult the API reference for the current contract.

Quick answer

How do I remove a watermark from a video with Medux MCP?

Connect either Codex or Claude to Medux MCP, prepare the required inputs, review the proposed medux_video_remove_watermark call, and verify the returned result. The tabs above keep client-specific prompting on one canonical page.

If the unwanted mark is specifically a brand logo, use the remove a logo from video with AI guide to compare logo-focused cleanup and review steps.

Can I use the same Medux tool in Codex and Claude?

Yes. The client interaction differs, but both use the same Medux MCP tool and API request contract shown in this tutorial.

AI video cleanup for authorized media

Use an AI video watermark remover through Medux API and MCP

Use this workflow to remove a watermark from video through the Medux video watermark removal API. Codex or Claude prepares the owned source clip, submits the AI video watermark remover task, monitors progress, and helps inspect the cleaned region for blur, flicker, or visible reconstruction artifacts.

Use watermark removal only for video you own or are authorized to edit. If the unwanted mark is specifically a static or moving brand logo, use the related logo-removal workflow so the input and review steps match the actual object.

Can Medux remove a watermark from video through an API?

Yes. The Medux processing tool can be called through MCP by Codex or Claude, with the source video and supported parameters reviewed before execution.

Does watermark removal also cover logos and text overlays?

Some marks are better handled by a logo-specific or object-removal workflow. Choose the operation that matches the overlay, motion, and available reference inputs.

Authorized media cleanup

Build a rights-aware video watermark removal API workflow

Use this AI video watermark remover only for media you own or are authorized to edit. Codex or Claude can expose the input, proposed tool arguments, asynchronous task ID, and cleaned result, creating an auditable video-processing workflow for developers.

For production or commercial publishing, retain the source license or permission, inspect the complete affected time range, and record who approved the final output.

Can I remove a watermark from any online video?

No. Use the workflow only when you own the video or have permission to modify it. The technical ability to process a file does not grant rights to the source media or embedded mark.
