What does this MCP actually do?

It calculates the math for video transitions. It helps you find the true duration of a video when clips overlap and tells you how much raw footage you need to hit a target length.

How do I use it with Claude or Cursor?

Vinkius hosts the MCP for you. You just connect your client to the Vinkius catalog, and your agent will automatically have access to the capabilities.

Does it work for all types of transitions?

This MCP is specifically designed for crossfade transitions where clips occupy the same space on the timeline.

Can I use it to plan my raw footage needs?

Yes. You can use the get_required_raw_sum capability to find out the total raw footage length needed for a specific final duration.

Is there a way to see how much time I'm losing to transitions?

Yes. The get_overlap_impact_report capability provides a breakdown of the time lost to junctions.

How does the duration calculation work?

The capability calculates the total sum of all clip durations and then subtracts the cumulative time lost at each junction. The number of junctions is always one less than the number of clips.

Can I use this to plan my footage requirements?

Yes, by using get_required_raw_sum, you can determine exactly how much raw clip length is needed to hit a specific target duration after all crossfades are applied.

What happens if the crossfade duration is too large?

If the crossfadeDuration exceeds the length of any clip in your sequence, the capability will return an error to prevent invalid calculations.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Curated set · 3 capabilities

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Crossfade Time Subtractor.

01
Get required raw sum
This capability calculates the total amount of raw footage length you need to reach a specific target duration. It accounts for the time lost during crossfades.
02
Get true duration
This capability finds the actual length of your final video sequence. It subtracts the overlap from the sum of individual clip lengths.
03
Get overlap impact report
This capability provides a breakdown of the time lost to transitions. It shows you exactly how much duration is consumed by your junctions.

Real work

What teams actually run

Social Media Ad Timing

Calculate if your clips will fit into a strict 15 or 30 second window once crossfades are added.

Footage Procurement

Determine the total raw footage length required to hit a specific target duration.

Timeline Auditing

Check how much total time is being consumed by transitions in a long sequence.

Pre-edit Planning

Plan the structure of a sequence by knowing the true duration of clips before they hit the timeline.

One connector, every AI

Crossfade Time Subtractor works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Crossfade Time Subtractor to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.
