Reel Quick: Added Video Transition Effects and a Theme Selector

I’ve been improving Reel Quick, an open-source Instagram reels generator built with FastAPI, Next.js, and ARQ. The latest update adds two practical frontend/video workflow improvements: video transition effects and a theme selector.

The transition work makes reel stitching feel more polished by adding support for scene transition effects between clips. For this release, I also added sample input/output media so the behavior is easy to inspect directly. On the UI side, Reel Quick now supports a theme selector with multiple appearance modes, making the interface more flexible for different working environments and user preferences.

What was added

• Video transition effects
• Sample transition input clips
• Sample output video showing a circle transition
• Theme selector demo output video
• Updated project documentation

Why this matters

For reel creation workflows, transitions improve the final viewing experience without forcing extra manual editing outside the tool. The theme selector improves usability for longer editing sessions and makes the app feel more production-ready.
