## Description

This MCP handles the math of syncing your video to a soundtrack. It's built for editors and motion designers who need to hit every beat perfectly without doing manual calculations. Instead of guessing where a cut should land, you can tell your agent the BPM and the length of your track, and it'll give you the exact millisecond timestamps for your timeline. It even figures out the speed factors you need to stretch or shrink a clip so the movement stays in time with the music. You'll find this MCP in the Vinkius catalog as a way to move from 'close enough' timing to frame-perfect sync. It takes the guesswork out of rhythmic editing by providing the precise data points needed for clean transitions. You no longer have to jump back and forth between your project file and a calculator. The AI does the heavy lifting of calculating the deltas and intervals, so you can just apply the numbers to your timeline. This ensures your edits feel intentional and professional, whether you're working on a high-energy music video or a subtle motion graphic loop. It turns a tedious manual process into a quick data request. It saves you from the frustration of tiny adjustments that don't quite land, letting you focus on the creative flow of your project instead of the technicalities of timecode. By automating the math, you can move faster through your timeline while maintaining a high standard of polish. It's about getting the technical details right so you can spend more time on the actual art of storytelling.

## Tools

### get_beat_interval
Tells you the millisecond duration of a single beat based on the BPM. Use this to set your timing.

### calculate_clip_snap
Gives you the specific adjustment needed to make a clip end on a beat. Use this for perfect rhythmic alignment.

### generate_sync_grid
Creates a complete list of timestamps for a beat grid over a set duration. Use this to map your entire timeline.

## Prompt Examples

**Prompt:** 
```
What's the beat duration for 128 BPM?
```

**Response:** 
```
For a song at 128 BPM, one beat lasts exactly **468.75 milliseconds**.

Here is the breakdown:
*   **BPM**: 128
*   **Seconds per beat**: 0.78125
*   **Milliseconds per beat**: 468.75
```

**Prompt:** 
```
Generate a beat grid for 30 seconds at 110 BPM.
```

**Response:** 
```
Here is your beat grid for a 30-second duration at 110 BPM:

| Beat | Timestamp (ms) |
|---|---|
| 1 | 0.00 |
| 2 | 545.45 |
| 3 | 1090.91 |
| 4 | 1636.36 |
| ... | ... |
| 30 | 15909.09 |
```

**Prompt:** 
```
I have a clip ending at 1200ms. How do I snap it to the nearest beat at 115 BPM?
```

**Response:** 
```
To snap your clip to the nearest beat at 115 BPM:

*   **Beat Interval**: 521.74 ms
*   **Current Position**: 1200 ms
*   **Nearest Beat**: 1565.22 ms
*   **Adjustment Needed**: +365.22 ms

Your clip needs to be stretched or moved by **365.22 ms** to hit the next beat perfectly.
```

## Capabilities

### Calculate beat duration
Determine exactly how many milliseconds a single beat lasts based on the BPM.

### Generate a full timeline of beat timestamps
Get a complete list of beat markers over a specific duration for your project.

### Determine exact clip adjustment values
Find the precise millisecond delta needed to snap a clip to the nearest beat.

### Find millisecond deltas for rhythmic alignment
Get the exact timing differences required to align visual cuts with audio pulses.

### Calculate speed factors for video stretching
Identify the speed percentage needed to stretch or shrink a clip to fit a beat.

## Use Cases

### Syncing a high-energy music video
An editor wants to ensure every transition hits a beat on a 128 BPM track. They ask the agent to generate a grid for a 30-second clip, and it provides the exact timestamps to snap the cuts to.

### Creating a looping motion graphic
A motion designer needs a loop to reset perfectly on a beat. They use the tool to find the exact speed factor and snap point to make the animation seamless.

### Rapid social media content batching
A creator wants to sync five different clips to the same audio track. They ask the agent to calculate the snap points for all five to ensure consistent rhythmic timing.

### Aligning lyric video text
A designer needs to know exactly when text should appear on screen. They generate a beat grid to get a list of timestamps for every word in the chorus.

## Benefits

- Stop doing mental math for BPM. Use `get_beat_interval` to instantly get the millisecond duration of a single beat, which removes the need for manual calculations during your edit.
- Achieve frame-perfect cuts. `calculate_clip_snap` ensures every transition hits the mark exactly, removing the 'almost there' feeling from your final export.
- Build your timeline faster. `generate_sync_grid` gives you a full roadmap of beats at once, so you don't have to generate them one by one as you work.
- Master complex video stretching. Get the exact speed factors needed to stretch or shrink a clip so it stays in time with the music without looking awkward.
- Eliminate human error. Automated math ensures that your rhythmic alignment stays consistent across long projects, regardless of how complex the audio track gets.

## How It Works

The bottom line is you get the exact math for rhythmic cuts without having to open a calculator or guess your frame counts.

1. Tell your agent the BPM and the start time of your audio track.
2. The MCP generates a full grid of beat timestamps for your desired duration.
3. You get the exact millisecond markers to use for your cuts and clip snaps.
