How this service works

HALOWERK medienwerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.

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?”

When 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

Input

Schema · Request body

Field	Type	Description
source	object	The video. Either url or content_base64.
max_scenes	integer	Ceiling on returned scenes. What is dropped is counted and reported.
max_thumbnails	integer	Ceiling on rendered thumbnails, independent of the scene count.
scene_threshold	number	Frame-to-frame difference above which a new scene starts. Lower finds more, higher finds fewer.
thumbnail_width	integer	Width of the thumbnails; height follows the aspect ratio.
duration_minutes	integer	Length of the video in started minutes — this is what you are billed for. A longer video is refused with its real duration and nothing is charged; a shorter one simply costs what you declared, and the answer says how much less it would have been.
min_scene_seconds	number	Merge cuts closer together than this. Guards against flicker being read as a cut.
include_thumbnails	boolean	Render one JPEG per scene and return it base64.
