## exec(cmd) ⇒ <code>Promise</code>
Shells out to execute a command with async/await.
	Async wrapper to exec module.

**Kind**: global function  
**Returns**: <code>Promise</code> - Promise containing the complete stdio  

| Param | Type | Description |
| --- | --- | --- |
| cmd | <code>string</code> | Command to execute |

<a name="delay"></a>

## delay(ms) ⇒ <code>Promise</code>
Delays process for specified amount of time in milliseconds.

**Kind**: global function  
**Returns**: <code>Promise</code> - Promise that resolves after set time  

| Param | Type | Description |
| --- | --- | --- |
| ms | <code>integer</code> | Milliseconds to delay for |

<a name="zeroPad"></a>

## zeroPad(i, max) ⇒ <code>string</code>
Pads a numerical value with preceding zeros to make strings same length.

**Kind**: global function  
**Returns**: <code>string</code> - Padded number as a string  

| Param | Type | Default | Description |
| --- | --- | --- | --- |
| i | <code>integer</code> |  | Number to pad |

**Kind**: global function  
<a name="frames"></a>

## frames(video, order) ⇒ <code>string</code>
Exports all frames from video. Appends number to the string
	to keep frames in alternating order to be quickly stitched together
 or re-sorted.

**Kind**: global function  
**Returns**: <code>string</code> - String with the export order, not sure why I did this  

| Param | Type | Description |
| --- | --- | --- |
| video | <code>string</code> | String representing path to video |
