# editing-videos output preview

## PART A: Task fit
- Use case: Performs video editing using the Volcengine cloud editing API with native Track structure. This applies to ALL filters: transform, crop, delogo, etc. { "Type": "transform", "PosX": 0, "PosY": 0, "Width": <canvaswidth>, "Height": <canvasheight> } runs entirely locally. Works with Claude Code, Cursor, Cline and 23 more..
- Inputs: target material, constraints, expected output, and acceptance criteria.
- Evidence boundary: follow “⚠️ CRITICAL: ALL PosX/PosY Are Top-Left Coordinates / When to Use / Workflow” and do not present inference as author intent.

## PART B: Execution result
- **01** The card summarizes the use case; runtime output centers on “Performs video editing using the Volcengine cloud editing API with native Track structure. This applies to ALL filters: transform, crop, delogo, etc. { "Type": "transform", "PosX": 0, "PosY": 0, "Width": <canvaswidth>, "Height": <canvasheight> } runs entirely locally. Works with Claude Code, Cursor, Cline and 23 more.”.
- **02** When the source has headings, the agent prioritizes “⚠️ CRITICAL: ALL PosX/PosY Are Top-Left Coordinates / When to Use / Workflow” so the result follows the author’s structure.
- **03** Typical output includes task judgment, concrete steps, required commands or file edits, validation, and follow-up options.
- **04** Risk context follows the fingerprint: read files, write/modify files; mostly runs locally; usually needs no extra API key.

## Running Rules
- read files, write/modify files; mostly runs locally; usually needs no extra API key.
- Validate with a small sample before expanding scope.
- Return the result, validation criteria, and next iteration options.

# editing-videos

## When to use
- Performs video editing using the Volcengine cloud editing API with native Track structure. This applies to ALL filters…
- Use it when the task has clear inputs, repeatable steps, and validation criteria.

## What to provide
- Target material, scope, expected result, and forbidden changes.
- Whether network, commands, file writes, or external services are allowed.

## Execution rules
- Organize steps around “⚠️ CRITICAL: ALL PosX/PosY Are Top-Left Coordinates / When to Use / Workflow” and keep inference separate from source facts.
- read files, write/modify files; mostly runs locally; usually needs no extra API key.
- Validate with a small sample before expanding the task.

## Output requirements
- Return the deliverable, key evidence, validation method, and next action.
- Mark missing information as unknown; do not invent commands, platforms, or dependencies.

Evidence boundary and execution chain

The author source anchors workflow facts; repository files anchor sources and commands; Fluxly only adds fit, limitations, and quality judgment.

skill "editing-videos" {
  input      -> user goal + target files + boundaries + acceptance criteria
  context    -> ⚠️ CRITICAL: ALL PosX/PosY Are Top-Left Coordinates / When to Use / Workflow
  rules      -> SKILL.md triggers / order / output contract
  runtime    -> no special runtime | read files, write/modify files | mostly runs locally
  guardrails -> usually needs no extra API key + small-sample validation + diff/log review
  output     -> copyable result + checklist + next iteration
}

Interpretation is structured for decision-making; original keeps the upstream SKILL.md unchanged.

Decide Fit First

Core job: Performs video editing using the Volcengine cloud editing API with native Track structure. This applies to ALL filters: transfor…
Best fit: Use it when the task has reusable inputs, steps, and validation criteria rather than a one-off answer.
Avoid forcing it: If the source lacks commands, platform support, or external-service evidence, keep those fields unknown instead of guessing.

Design Intent

Structure: The skill is organized around “⚠️ CRITICAL: ALL PosX/PosY Are Top-Left Coordinates”, “When to Use”, “Workflow”, “Step 1: Get Video Information (Required)”, showing how the author expects the agent to judge fit, collect context, and produce verifiable output.
Trigger evidence: Prioritize the author’s wording around when to use it, what context to collect, and what output shape to produce.
Evidence boundary: Author text states facts, repository files prove commands and paths, and Fluxly only adds fit, limits, and usage judgment.

How To Use It

Inputs: Provide target material, scope, expected result, forbidden changes, and validation method.
Invocation: Name editing-videos directly; if the source includes slash commands, start with the command and then add task context.
Validation: Start small and check whether the result follows “⚠️ CRITICAL: ALL PosX/PosY Are Top-Left Coordinates / When to Use / Workflow” before expanding.

Boundaries And Review

Dependencies: It usually needs no extra API key, so start with a small validation task.
Permissions: Declared permissions include read / write; ask the agent to state file, command, and rollback boundaries before acting.
Quality bar: A useful result names the deliverable, evidence, and next action. Generic prose means the task needs tighter context.

Video Editing with Track Structure

Performs video editing using the Volcengine cloud editing API with native Track structure.

⚠️ CRITICAL: ALL PosX/PosY Are Top-Left Coordinates

ALL PosX/PosY values in this API are TOP-LEFT corner coordinates, NOT center point!

This applies to ALL filters: transform, crop, delogo, etc.

For full-screen video display, you MUST use:

{ "Type": "transform", "PosX": 0, "PosY": 0, "Width": <canvas_width>, "Height": <canvas_height> }

NEVER use canvas center coordinates (like 640, 360) for PosX/PosY!

Using center coordinates will cause video to display off-canvas
The coordinate (0, 0) is the top-left corner of the canvas

When to Use

Use this skill when:

Cutting or trimming video segments
Adding text, watermarks, or stickers to videos
Adding or replacing audio tracks
Applying filters or visual effects
Merging multiple video clips
Adding transitions between clips
Changing video playback speed
Removing watermarks (logo blur)

Workflow

Step 1: Get Video Information (Required)

ALWAYS call uploadAndGetVid first to:

Upload video to Volcengine cloud
Get VID for video source reference (format: vid://xxx)
Get Duration for time calculations (in seconds)
Get Dimensions (width, height) for Canvas setup

If you only need metadata without editing (e.g., for display purposes), use probeVideoMetadata instead.

Step 2: Build EditParam

Construct your EditParam following the structure below.

Step 3: Submit Task

Call submitDirectEditTask with Canvas, Output (optional), and Track.

Step 4: Poll for Results

First check: Wait 90 seconds after submission
Subsequent checks: Wait 30 seconds between polls
Call getVideoEditTaskStatus to check progress
Maximum wait time: 20 minutes

Step 5: Return Results

On completion, return the output video URL to user.

EditParam Structure

{
  "Canvas": { "Width": 1920, "Height": 1080 },
  "Output": { "Fps": 30, "Codec": { "VideoCodec": "h264" } },
  "Track": [
    [{ "Type": "video", "Source": "vid://xxx", "TargetTime": [0, 5000] }],
    [{ "Type": "text", "Text": "Hello", "TargetTime": [0, 5000], "Extra": [] }]
  ]
}

Canvas (optional):

If omitted, auto-detected from the primary video source dimensions
If provided manually, MUST match getVideoInfo/uploadAndGetVid output
Width = horizontal pixels, Height = vertical pixels
Example: 1280x720 video → { Width: 1280, Height: 720 } — NOT { Width: 720, Height: 1280 }


**Time unit**: All time values are in **MILLISECONDS** (1 second = 1000 ms)

## Track Structure

Track is a **2D array** `Track[layerIndex][elementIndex]`:

- Outer array: Rendering layers (higher index = higher layer, renders on top)
- Inner array: Elements on the same track

## Element Types

### video

```json
{
  "Type": "video",
  "Source": "vid://your_vid",
  "TargetTime": [0, 5000],
  "Extra": [
    { "Type": "trim", "StartTime": 10000, "EndTime": 30000 }
  ]
}

audio

{
  "Type": "audio",
  "Source": "vid://your_audio_vid",
  "TargetTime": [0, 10000],
  "Extra": [
    { "Type": "a_volume", "Volume": 0.5 }
  ]
}

When to use audio elements:

Adding background music to video
Adding voiceover/narration
Adjusting audio volume separately from video
Replacing original audio with different audio

When NOT to use audio elements:

Simple video concatenation - video elements already contain their audio tracks
When you want to keep the original video audio unchanged

image

{
  "Type": "image",
  "Source": "mid://your_image_mid",
  "TargetTime": [0, 3000],
  "Extra": [
    { "Type": "transform", "PosX": 100, "PosY": 100, "Width": 200, "Height": 200 }
  ]
}

text

{
  "Type": "text",
  "Text": "Your Text Here",
  "TargetTime": [0, 5000],
  "FontType": "SY_Black",
  "FontSize": 120,
  "FontColor": "#FFFFFFFF",
  "AlignType": 1,
  "Extra": [
    { "Type": "transform", "PosX": 60, "PosY": 440, "Width": 1800, "Height": 200 }
  ]
}

subtitle

{
  "Type": "subtitle",
  "Text": "http://example.com/subtitle.srt",
  "TargetTime": [0, 20000],
  "FontType": "ALi_PuHui",
  "FontSize": 60,
  "Extra": [
    { "Type": "transform", "PosX": 40, "PosY": 550, "Width": 1200, "Height": 150 }
  ]
}

Filter Types (Extra)

transform - 2D Transform

Controls element position, size, rotation, and opacity on the canvas.

IMPORTANT:

PosX and PosY are the TOP-LEFT corner coordinates of the element relative to the canvas top-left corner
They are NOT center point coordinates
Rotation is performed around the element's center point

Parameters:

PosX: X coordinate of element's top-left corner (pixels)
PosY: Y coordinate of element's top-left corner (pixels)
Width: Element width on canvas (pixels)
Height: Element height on canvas (pixels)
Rotation: Rotation angle [-360, 360], clockwise is positive (optional)
Alpha: Opacity [0,1], 0 is transparent (optional)

Basic Example (fill canvas):

{ "Type": "transform", "PosX": 0, "PosY": 0, "Width": 1920, "Height": 1080 }

Rotation Example (rotate 1280x720 video 90° to fit 720x1280 canvas):

When rotating, the element rotates around its center. To fill a 720x1280 canvas with a 1280x720 video rotated 90°:

After rotation, the video's display size becomes 720x1280
The center should be at canvas center (360, 640)
Calculate: PosX = 360 - 1280/2 = -280, PosY = 640 - 720/2 = 280

{ "Type": "transform", "PosX": -280, "PosY": 280, "Width": 1280, "Height": 720, "Rotation": 90 }

Centering Formula:

To center an element horizontally: PosX = (CanvasWidth - ElementWidth) / 2
To center an element vertically: PosY = (CanvasHeight - ElementHeight) / 2

Example: Center a 600x60 subtitle on 720x1280 canvas:

PosX = (720 - 600) / 2 = 60
PosY = 1280 - 100 = 1180 (near bottom)

Common Mistakes:

WRONG: Using canvas center (360, 640) or (640, 360) as PosX/PosY - this places the element's top-left at center, causing it to go off-canvas
WRONG: Omitting transform for full-screen video elements - video may not display correctly without explicit positioning
WRONG: Creating separate audio tracks for each video clip in simple concatenation - video elements already contain their audio
CORRECT: Use (0, 0) for top-left alignment when video should fill the canvas
CORRECT: Only add audio tracks when you need background music, voiceover, or volume adjustment

Examples

Example 1: Simple Video Concatenation (Most Common)

{
  "Canvas": { "Width": 1920, "Height": 1080 },
  "Track": [[
    {
      "Type": "video",
      "Source": "vid://video1",
      "TargetTime": [0, 5000],
      "Extra": [
        { "Type": "transform", "PosX": 0, "PosY": 0, "Width": 1920, "Height": 1080 }
      ]
    },
    {
      "Type": "video",
      "Source": "vid://video2",
      "TargetTime": [5000, 12000],
      "Extra": [
        { "Type": "transform", "PosX": 0, "PosY": 0, "Width": 1920, "Height": 1080 }
      ]
    },
    {
      "Type": "video",
      "Source": "vid://video3",
      "TargetTime": [12000, 20000],
      "Extra": [
        { "Type": "transform", "PosX": 0, "PosY": 0, "Width": 1920, "Height": 1080 }
      ]
    }
  ]]
}

Key points for video concatenation:

Transform with PosX: 0, PosY: 0 is REQUIRED for full-screen display
NO separate audio tracks - video elements already contain their audio
All video clips on the same track (single inner array)
Sequential TargetTime: video2 starts where video1 ends

Example 2: Concatenate Videos with Transition

{
  "Canvas": { "Width": 1920, "Height": 1080 },
  "Track": [[
    {
      "Type": "video",
      "Source": "vid://video1",
      "TargetTime": [0, 5000],
      "Extra": [
        { "Type": "transform", "PosX": 0, "PosY": 0, "Width": 1920, "Height": 1080 },
        { "Type": "transition", "Source": "1182376", "Duration": 1000 }
      ]
    },
    {
      "Type": "video",
      "Source": "vid://video2",
      "TargetTime": [4000, 9000],
      "Extra": [
        { "Type": "transform", "PosX": 0, "PosY": 0, "Width": 1920, "Height": 1080 }
      ]
    }
  ]]
}

Note: With transitions, TargetTime values overlap (video2 starts at 4000, video1 ends at 5000).

Example 3: Trim Video (10s to 30s)

{
  "Canvas": { "Width": 1920, "Height": 1080 },
  "Track": [[
    {
      "Type": "video",
      "Source": "vid://xxx",
      "TargetTime": [0, 20000],
      "Extra": [
        { "Type": "trim", "StartTime": 10000, "EndTime": 30000 }
      ]
    }
  ]]
}

Example 4: Add Text Watermark

{
  "Canvas": { "Width": 1920, "Height": 1080 },
  "Track": [
    [{ "Type": "video", "Source": "vid://xxx", "TargetTime": [0, 10000] }],
    [{
      "Type": "text",
      "Text": "@MyChannel",
      "TargetTime": [0, 10000],
      "FontType": "SY_Black",
      "FontSize": 60,
      "FontColor": "#FFFFFFFF",
      "Extra": [
        { "Type": "transform", "PosX": 1700, "PosY": 50, "Width": 200, "Height": 60 }
      ]
    }]
  ]
}

Example 5: Add Background Music

{
  "Canvas": { "Width": 1920, "Height": 1080 },
  "Track": [
    [{ "Type": "video", "Source": "vid://video", "TargetTime": [0, 30000] }],
    [{
      "Type": "audio",
      "Source": "vid://music",
      "TargetTime": [0, 30000],
      "Extra": [
        { "Type": "a_volume", "Volume": 0.3 }
      ]
    }]
  ]
}

Example 6: Apply Filter

{
  "Canvas": { "Width": 1920, "Height": 1080 },
  "Track": [[
    {
      "Type": "video",
      "Source": "vid://xxx",
      "TargetTime": [0, 10000],
      "Extra": [
        { "Type": "lut_filter", "TargetTime": [0, 10000], "Source": "1183993", "Intensity": 0.8 }
      ]
    }
  ]]
}

Example 7: Logo Blur (Watermark Removal)

{
  "Canvas": { "Width": 1920, "Height": 1080 },
  "Track": [[
    {
      "Type": "video",
      "Source": "vid://xxx",
      "TargetTime": [0, 10000],
      "Extra": [
        { "Type": "delogo", "TargetTime": [0, 10000], "PosX": 1700, "PosY": 50, "Width": 200, "Height": 80, "Sigma": 30, "Radius": 30 }
      ]
    }
  ]]
}

Example 8: Rotate Landscape Video to Portrait

Convert a 1280x720 (landscape) video to 720x1280 (portrait) canvas:

{
  "Canvas": { "Width": 720, "Height": 1280 },
  "Track": [[
    {
      "Type": "video",
      "Source": "vid://xxx",
      "TargetTime": [0, 10000],
      "Extra": [
        {
          "Type": "transform",
          "PosX": -280,
          "PosY": 280,
          "Width": 1280,
          "Height": 720,
          "Rotation": 90
        }
      ]
    }
  ]]
}

Calculation:

Original video: 1280x720, Canvas: 720x1280
After 90° rotation, video displays as 720x1280
Rotation center = (PosX + Width/2, PosY + Height/2) should equal canvas center (360, 640)
PosX = 360 - 1280/2 = -280
PosY = 640 - 720/2 = 280

Important Notes

Always call uploadAndGetVid first - Required for VID and dimensions
Time unit is milliseconds - 1 second = 1000 ms
Track layers render bottom to top - Track[0] is bottom, Track[1] is above it
Transition duration must < clip duration
Subtitle tracks must be separate - Each subtitle occupies one track, max 10 subtitle tracks
Maximum processing time: 20 minutes
Full-screen video requires transform with PosX: 0, PosY: 0 - Do NOT use canvas center coordinates like (640, 360) or (360, 640)
Video elements already contain audio - Do NOT create separate audio tracks for simple video concatenation; only use audio tracks for background music, voiceover, or volume adjustment
Canvas is optional — omit it for auto-detection from video sources; only specify manually for custom canvas sizes
