🎬Video Scene Log Generator
Analyzes a video, finds the moments where the screen changes significantly and builds a timestamped log. Add notes to each scene, then export them as YouTube chapters or as images for a how-to guide.
Your video is never sent to a server (processed in your browser)
Leave blank to analyze the whole video. “Current position” fills in where the preview is paused.
How to use
- Choose the video you want to analyze (or drag and drop it).
- Pick a video type. “Slides & screen recordings” suits slides and screen captures; “Camera footage” suits videos shot with a camera.
- Click “Detect scenes” to list the moments where the screen changed significantly. For long videos, you can analyze just part of it with “Range”.
- Click a time to play the preview from there. Click a thumbnail to enlarge it, and use the ← → keys to move between scenes.
- Add a note to each scene and remove the ones you don’t need with “✕”. To add a missing scene, pause the preview and click “+ Add scene at current position”.
- Choose a format, then copy it or save it as a file. Scene images can also be saved as a ZIP or an overview image.
No AI — it just measures how much the picture changes
This tool samples frames at the interval you set and measures how much each one differs from the previous frame. Where the change is large, it treats it as a scene change, then checks that stretch more closely to record a time close to the actual cut (to about 0.2 seconds). Slow fades and gradual scrolling are also detected once the picture has moved far enough from the previous scene.
It doesn’t understand what’s on screen, so it works best for videos with clear cuts, such as slides and screen recordings. For camera footage with lots of movement, choose “Camera footage” or move “Sensitivity” toward Low.
Export formats
- Text: one line per scene, like “0:12 - note”. For work logs and notes
- YouTube chapters: paste into your video’s description to show chapters. The first one always starts at 0:00, and you’ll see a warning if YouTube’s rules (at least 3 chapters, each at least 10 seconds) aren’t met
- Markdown and CSV: easy to paste into minutes, documents or Excel
- Scene images as ZIP: saves each scene at its original resolution (up to 1920px). For how-to guides
- Overview image: thumbnails with times and notes on one image, for sharing in chat
Handy for
- Turning a screen recording into step-by-step screenshots for a how-to guide
- Adding chapters to a lecture, seminar or slide recording
- Listing when the shared slides changed in a meeting recording
- Quickly finding the moments where something changed in a long screen recording
