I've updated the code. To fix Showcase #04 without changing your logic, I simply added #before-mask-04 to your CSS declaration. This ensures that the pink slider border and positioning are applied to the fourth section so it matches the first three. HTML The Edit Mastery | Joostech Media

Raw footage taken from Kool Shooters and Tima Miroshinchenko. Total footage of approximately 5 minutes and edited into a short form approximately 1m 30s, more suitable for social media. Stock music added and synced to footage, minor colour correction and grading

Showcase #03

The Happy/Sad
Mood Change

Same Footage, Different Soul. 🎬 We took three simple clips of a man at a desk and tried to tell two opposite stories using only DaVinci Resolve. 🖥️ (Footage from: Mikhail Nilov) By adjusting the colour temperature 🟦, changing the pacing ⏱️, and adding environmental reverb 🔊, I transformed a productive afternoon into a moment of deep isolation. It goes to show: An editor doesn't just cut clips—they craft emotions.
