It works on Google Chrome, Mozilla Firefox, and Microsoft Edge. It is distributed through the Chrome Web Store, Firefox Add-ons, and Edge Add-ons at zero cost with no premium tier, no ads, and no telemetry beyond anonymised crash reporting. The extension is maintained by Ahsan Mahmood and the Video Controls Plus community. The project is open-source in spirit (public docs, transparent roadmap, user-voted features) and its source code and companion website (https://vcpeai.aoneahsan.com) are actively developed. --- ## 2. Core features ### 2.1 Playback speed control - Continuous range from 0.1x to 4x (up to 16x on supported platforms). - 0.1x increments via `[` (slower) and `]` (faster). - Reset to 1x with `=`. - Number-key presets `1`–`8` map to common speeds (0.25x, 0.5x, 0.75x, 1x, 1.25x, 1.5x, 2x, 3x). - Works across tabs; settings persist per-domain. ### 2.2 A-B loop - `Alt + A` marks loop start (point A). - `Alt + B` marks loop end (point B). - `Alt + L` toggles looping between A and B. - Ideal for language learning, music practice, code-tutorial revision, and dance choreography. ### 2.3 Audio boost - Boost audio up to 400% of the player's native maximum. - `Alt + U` raises boost, `Alt + Y` lowers it, `Alt + N` applies safe normalisation. - Useful for lectures and interviews recorded at low levels. ### 2.4 Video filters - Real-time brightness, contrast, saturation, hue, blur, grayscale, and invert. - Non-destructive (applied via CSS filters); original stream untouched. ### 2.5 One-click screenshots - Captures the current video frame as PNG. - Saved locally; accessible at /screenshots on the website. ### 2.6 Timestamped notes - Write notes pinned to the current playback position. - Clicking a note seeks the video to that timestamp. - Exportable as Markdown or plain text. ### 2.7 Cloud sync (optional) - Firebase-backed.
