How to remove an object from a video with Medux MCP
Learn to remove an object from a video with the Medux API through Codex or Claude MCP. Check inputs, tool calls, task status, and output.

Follow the Codex or Claude workflow
The Medux operation and request fields are shared. Switch tabs for the client-specific prompt, approval pattern, screenshots, and walkthrough.
Codex-specific workflow
Run Remove an Object from Video as a Codex MCP task
Use the active workspace as the source of truth. Ask Codex to identify the source video and precise mask regions for the object to remove, select medux_remove_video_object, 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_remove_video_object through Medux MCP to remove an object from a video.
First inspect and identify the source video and precise mask regions for the object to remove.
Show me the exact tool arguments before execution.
After the task completes, return the cleaned video and verify that the intended object 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 intended object is removed through the required frames without damaging unrelated regions.
What this tutorial does
Medux operation
Remove an object from a video by mask regions.
Agent workflow
Codex selects medux_remove_video_object, presents the arguments for review, calls Medux, and reports the response.
Before you start
Authentication
- Authentication is required via Authorization header.
Preconditions
- Upload the source file and create a file reference before calling this endpoint.
- Successful requests return a Medux task record immediately. Use the task query or sync endpoints to track completion.
- All file inputs must be uploaded and persisted as file references before submission.
Prompt Codex
Start with a clear instruction that names the Medux operation and the intended inputs.
Remove an object from a video by mask regions.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.
| Field | Type | Requirement | Purpose |
|---|---|---|---|
input_file_id | string | Required | Input video file id. |
mask_regions | object | Required | Regions to remove, e.g. [[x, y, width, height]]. |
model_id | string | Optional | Model Default: remove-video-object-default. |
title | string | Optional | Optional task title. |
Step-by-step workflow
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 Remove Video Object
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_remove_video_object 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.

Can Codex use the Medux Remove Video Object API through MCP?
Codex can call the medux_remove_video_object Medux MCP tool to remove an object from a video by mask regions. 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_remove_video_object. Review its arguments before approval and consult the API reference for the current contract.
Claude-specific workflow
Run Remove an Object 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 precise mask regions for the object to remove before proposing medux_remove_video_object. 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 an object from a video with Medux MCP.
Restate which input fulfills each role: the source video and precise mask regions for the object to remove.
Propose the medux_remove_video_object call and summarize its arguments before asking for approval.
When it finishes, return the cleaned video with a checklist confirming that the intended object 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 intended object is removed through the required frames without damaging unrelated regions.
