Adjust Video Width in Shopify Code

I'm looking to fix some code to make a self-hosted MP4 video wider on a webpage. The code is currently running on HTML/CSS/JavaScript.

Requirements:
- Modify existing code to adjust video width
- Ensure the video displays correctly across different browsers and devices
- No quality loss in video after width adjustment

Ideal Skills and Experience:
- Proficient in HTML, CSS, and JavaScript
- Experience with video embedding and manipulation
- Attention to detail and problem-solving skills

Make #2 look like #1 but the video needs to go to the right hand side and more width. Also make the text look the same as #1 after fix.
