Analyzes a video (by URL or base64) using FFmpeg frame-difference analysis to detect scene boundaries and return timestamps, durations, and detection scores for each scene.

How this service works
Takes a video by URL or inline base64 and reports where the picture changes. FFmpeg measures the difference between consecutive frames; every jump above the threshold starts a new scene, and the answer lists each scene with start, end, duration and the fraction of the running time it covers, plus the raw detection score positions.
Output
A list of detected scenes, each with its start time, end time, duration, fraction of total video runtime, and raw FFmpeg frame-difference detection score at that boundary point.
Example use cases
Chapter markers for video editor
“I'm editing a long interview video at https://cdn.example.com/interview.mp4 — can you find every scene cut and give me the start and end timestamps for each scene so I can use them as chapter markers?”
Automated highlight reel segmentation
“Here's a sports broadcast clip as a base64 video. Detect all the scene changes and tell me the duration and fraction of total runtime for each segment so I can pick the longest continuous scenes for a highlight reel.”
Quality check for ad-break detection
“I need to verify where the scene transitions happen in this commercial video at https://media.example.com/ad_spot.mp4 — can you run scene detection and give me the raw detection scores and cut positions?”
Technical details
Endpoint
POSThttps://medien.halowerk.com/v1/keyframesWhen to prefer
Choose this endpoint when you need timestamped scene boundary data from a video, especially when you want FFmpeg-level precision with raw detection scores. Prefer this over manual frame extraction when you need the full list of scene segments with duration fractions in a single call. Best suited for workflows that chapter-mark, summarize, or segment video content automatically.
Side effects
- Video URL is inaccessible or returns a non-200 response
- Base64 payload is malformed or not a valid video format
- Video is too short or has no detectable scene changes — returns empty scene list
- Threshold parameter set too high causing all cuts to be missed
- Threshold parameter set too low causing noise to be detected as scenes
- Unsupported video codec or container format
- Network timeout for large remote video files
