Photo Slideshow Maker

😫 The Pain Point

You have 100 vacation photos. You want a video to post on Facebook. Dragging 100 photos into a timeline editor and adjusting duration for each is tedious.

🚀 Agentic Solution

One-Click Slideshow: Folder + Music = Video.

Key Features:

• Beat Sync: Calculates photo duration to match music length.
• Resizing: Automatically adds black bars (padding) so landscape and portrait photos fit the same video.

⚔️ Phase 1: Commander (Quick Fix)

For a quick memory video.

Prompt:

“Create a slideshow video from the ‘Photos’ folder using ‘music.mp3’ as background. 3 seconds per image. Use crossfade transition.”

Result: An MP4 video.

🏗️ Phase 2: Architect (Permanent Tool)

For Content Creators.

Engineering Prompt:

**Role:** Python Video Editor
**Task:** Create a "Batch Slideshow Generator".
**Requirements:**

🧠 Prompt Decoding

• Uniformity: If you mix vertical phone photos with horizontal camera photos, the video glitches. The engineering prompt explicitly asks to “resize to 1920x1080” to handle this aspect ratio mismatch.
