What this skill does

# Fal Video

Generate AI videos using Fal.ai Seedance models. Use when you need to: (1) animate images into short videos, (2) create motion from still photos, or (3) generate high-quality video content from images.

## Input

Provide input as JSON:

```json
{
  "input_image": "<file-id>",
  "motion_prompt": "Describe the motion or animation you want (e.g., 'camera slowly zooms in', 'character waves hand', 'leaves gently swaying in wind')",
  "video_duration": "Desired video duration in seconds (typically 3-10 seconds)"
}
```

**Note on File Input:**
- `input_image` requires a **file ID** (format: `df-xxxxx`)
- **How to get file ID:**
  1. Upload your image file to Refly using `refly file upload <file-path>`
  2. Copy the returned file ID from the upload response
  3. Use this file ID in the input JSON

## Execution (Pattern A: File Generation)

### Step 0: Upload Image File

```bash
# Upload your image
IMAGE_RESULT=$(refly file upload /path/to/your/image.jpg)
IMAGE_FILE_ID=$(echo "$IMAGE_RESULT" | jq -r '.payload.fileId')
echo "Image file ID: $IMAGE_FILE_ID"
```

### Step 1: Run the Skill and Get Run ID

```bash
# Use the IMAGE_FILE_ID from Step 0
RESULT=$(refly skill run --id skpi-aeg736kbicr5zzzwgiyn7me3 --input '{
  "input_image": "'"$IMAGE_FILE_ID"'",
  "motion_prompt": "gentle camera zoom in",
  "video_duration": "5"
}')
RUN_ID=$(echo "$RESULT" | jq -r '.payload.workflowExecutions[0].id')
```

### Step 2: Open Workflow in Browser and Wait for Completion

```bash
open "https://refly.ai/workflow/c-ly9fy5c2gz4hrf1g2izv5bdj"
refly workflow status "$RUN_ID" --watch --interval 30000
```

### Step 3: Download and Show Result

```bash
# Get files from this run
FILES=$(refly workflow toolcalls "$RUN_ID" --files --latest | jq -r '.payload.files[]')

# Download and open each file
echo "$FILES" | jq -c '.' | while read -r file; do
  FILE_ID=$(echo "$file" | jq -r '.fileId')
  FILE_NAME=$(echo "$file" | jq -r '.name')
  if [ -n "$FILE_ID" ] && [ "$FILE_ID" != "null" ]; then
    refly file download "$FILE_ID" -o "$HOME/Desktop/${FILE_NAME}"
    open "$HOME/Desktop/${FILE_NAME}"
  fi
done
```

## Expected Output

- **Type**: Video
- **Format**: .mp4 video file
- **Location**: `~/Desktop/`
- **Action**: Opens automatically to show user
