App Behavior Summary

The app is a custom HTML5 video player titled "KC2349 Video Player", built for Cornell Tech's Spring 2026 Producing Technologies course. It presents a single centered video player with a dark control bar and course branding ("Cornell Tech • Spring 2026") above the player.

The player supports the following controls:

On initial page load, the time counter reads 0:00 / 0:00 and playback speed shows 1x, indicating the player is in a waiting/idle state before a video source is loaded.

Things That Didn't Work as Expected

• LOAD button provides no input field: There is a LOAD button but no visible text field or file picker to specify which video URL or file to load. It is unclear to a first-time user what clicking LOAD will do or where the video source comes from.
• No visible progress/seek bar: The control bar shows a time counter (0:00 / 0:00) but there is no clickable progress bar, so scrubbing to a specific timestamp by mouse is not possible — only keyboard arrow-key seeking in 5-second steps works.
• Keyboard shortcuts only work when player has focus: After clicking elsewhere on the page (e.g., the browser address bar), all keyboard shortcuts silently stop responding with no visual indication that focus was lost.
• Playback speed is displayed but not changeable: The 1x speed indicator is visible, but there is no button or menu to switch to 1.5x or 2x, making the display feel like a placeholder rather than a functional control.

Prompt to Improve the App

Improve this video player app with the following changes:

1. Add a video URL input field: Place a text input and a "Load" button above the player so users can paste any MP4 URL to load it. Show a placeholder like "Paste video URL here…" so the purpose is immediately clear.
2. Add a clickable progress / seek bar: Render a horizontal scrubber bar between the video and the control row. It should update in real time as the video plays and allow clicking or dragging to jump to any timestamp.
3. Add a playback speed selector: Replace the static 1x label with a dropdown or segmented button offering 0.5×, 1×, 1.25×, 1.5×, and 2× options.
4. Auto-refocus the player after user interactions: When the user clicks anywhere inside the player container, restore keyboard focus automatically so arrow-key and space-bar shortcuts continue to work without needing a separate click on the video element.
5. Show a keyboard shortcut overlay: Add a ? button in the control bar that toggles a small help overlay listing all available keyboard shortcuts, so new users can discover the controls without reading documentation.
