# Video Encoding App

## Overview
This app takes a video file and an IMDb ID as input, generates a shell script to encode the video streams to AV1 and audio streams to Opus format, converts anamorphic video to SAR 1:1, and adds metadata from OMDB while stripping all other metadata.

## Input Requirements
1. **Video File**: A valid video file in a supported format.
2. **IMDb ID**: A valid IMDb ID to fetch metadata from OMDB.

## Optional CLI Arguments
1. **`-ns`/`--nosubtitles`**: Disables subtitle processing.
2. **`-p`/`--preset`**: Sets the encoding preset for the video. Default is `2`.
3. **`-c`/`--crf`**: Sets the CRF value for the video. Default is `30`.
4. **`-o`/`--original-media-type`**: Sets the ORIGINAL_MEDIA_TYPE metadata. Default is `DVD`.

## Output Details
The app generates a shell script that performs the following tasks:
1. Encodes the video to AV1 format.
2. Encodes the audio to Opus format.
3. Converts anamorphic video to SAR 1:1.
4. Adds metadata from OMDB using the provided IMDb ID.
5. Strips all other metadata from the video.

## Metadata Handling
- **Added Metadata**: Metadata fetched from OMDB using the IMDb ID.
- **Stripped Metadata**: All other metadata is removed from the video.

## Anamorphic Video Conversion
Anamorphic videos are converted to SAR (Sample Aspect Ratio) 1:1 to ensure proper display on all devices.

## Example Usage
```bash
./encode_video.sh input_video.mp4 -i tt1234567
