Release Notes

PySceneDetect 0.7.2 ships improved defaults for the histogram and perceptual hash detectors, adds PyAV 19 support, and fixes several timing and output bugs. Default output of detect-hist and detect-hash will change in this release due to improved default values.

CLI Changes

• [improvement] HistogramDetector (detect-hist) default threshold changed from 0.05 to 0.20 and default bins from 256 to 128, calibrated from the benchmarks. Output for this detector will change if you are not setting both parameters explicitly. #​559
  • Use detect-hist -t 0.05 -b 256 or HistogramDetector(threshold=0.05, bins=256) to restore the previous behavior.
• [improvement] HashDetector (detect-hash) default threshold changed from 0.395 to 0.35 and default size from 16 to 8, calibrated from the benchmarks. Output for this detector will change if you are not setting both parameters explicitly. #​559
  • Use detect-hash -t 0.395 -s 16 or HashDetector(threshold=0.395, size=16) to restore the previous behavior.
• [improvement] detect-threshold now ignores fade-outs shorter than 0.1s by default. Use --min-out-length 0 to restore the previous behavior. The API default remains 0 #​278
• [feature] Added save-keyframes command to export detected cuts using # keyframe format v1 for Aegisub-compatible tools #​534. Frame numbers are currently approximate for VFR input #​569
• [feature] Add --min-out-length/min_out_length to detect-threshold/ThresholdDetector, which requires that fades stay below the threshold for the given duration #​278
• [general] -f, --frame-rate, and --framerate are now aliases of the same CLI option, and all forms appear in help and documentation. If multiple forms are given, the last value is used #​548
• [bugfix] Progress bar now reaches 100% when processing variable framerate (VFR) videos, with both the OpenCV and PyAV backends #​561
• [bugfix] Fix AdaptiveDetector / detect-adaptive emitting scenes shorter than min_scene_len when window_width is large, by applying the minimum-length check to the emitted (target) frame instead of the current frame #​408

API Changes

• [api] Legacy framerate argument aliases in FrameTimecode, open_video(), and the video backends now emit a DeprecationWarning; use frame_rate instead. When both forms are provided, frame_rate takes precedence #​548
• [api] write_scene_list() now also accepts a path (str or pathlib.Path) as the first argument in addition to an open file handle; paths are opened and closed automatically #​523
• [api] Scene-list output functions for EDL, FCPXML, FCP7 XML, and OTIO now accept an open text file handle, a string path, or a pathlib.Path; paths are opened and closed automatically #​567
• [bugfix] ThresholdDetector/detect-threshold with method CEILING now classifies the first frame with the CEILING rule instead of the FLOOR rule, which anchored a leading fade one frame late and could emit a spurious cut at the first frame (thanks @​MuhammadBilalKhan267)
• [bugfix] Fix min_scene_len given in frames dropping cuts that are exactly min_scene_len frames apart at NTSC framerates (e.g. 29.97 fps), by comparing frame counts instead of converting to seconds #​577
• [bugfix] Fix TypeError when opening videos with the pyav backend on PyAV 19.0 or newer (PyAV 19 is now supported)
• [bugfix] Fix pyav backend duration calculation fallback
• [bugfix] Fix pyav backend not releasing the file handle it opened when the stream is garbage collected, which emitted a ResourceWarning under python -X dev #​568
• [bugfix] Work around an intermittent segfault on exit with the OpenCV backend on Windows when opening PNG image sequences with opencv-python 4.14 or 5.0 (upstream: opencv/opencv#30017) #​575

Packaging

• [general] The Windows distribution now bundles PyAV 19 and FFmpeg 9.0
• [general] The scenedetect-core package introduced in 0.7.1 has been discontinued, and its only release (0.7.1) yanked from PyPI. Existing scenedetect-core installs keep working but will not receive updates. Install either scenedetect or scenedetect-headless. #​558

v0.7.1: PySceneDetect v0.7.1

Release Notes

PySceneDetect 0.7.1 adds support for concatenating multiple videos, along with several stability and robustness fixes for the PyAV and OpenCV backends.

CLI Changes

• [feature] split-video has a new --expand flag: when scenes are detected within a time window (-s/-e), the first output clip is extended back to the start of the video and the last clip is extended forward to the end, so no footage outside the analysis window is dropped #​115

API Changes

• [feature] scenedetect.detect() now accepts a backend keyword argument ("opencv", "pyav", or "moviepy") similar to open_video. Defaults to "opencv", matching prior behavior.
• [feature] Add expand_scenes_to_bounds() helper in scenedetect.scene_manager to extend a scene list so the first scene starts at a given lower bound and the last scene ends at a given upper bound
• [feature] VideoStream now provides a public read-only decode_failures property reporting the number of frames that failed to decode and were skipped (defaults to 0; populated by the OpenCV and PyAV backends)
• [feature] Add VideoStreamConcat (scenedetect.backends.concat) which concatenates multiple videos into a single continuous stream with a monotonic PTS timeline; open_video() and detect() now accept a list of paths. VideoStreamConcat.map_span() maps spans of the global timeline back to per-source local times
• [bugfix] The PyAV backend (VideoStreamAv) now skips corrupt frames during read() and continues decoding instead of failing, giving up only after 8 consecutive decode failures (matching the OpenCV backend's tolerance behavior)
• [bugfix] The PyAV backend now normalizes presentation times by the stream start time, so files with a delayed start (e.g. from edit lists) report the first frame at position 0, consistent with other backends and with seek()
• [bugfix] Comparisons between two FrameTimecode objects that both carry exact presentation times (e.g. positions from VFR videos) and share the same frame rate are now performed exactly using pts and time_base instead of rounded frame numbers. Previously, distinct frames in VFR sections could compare equal or fail strict ordering when their times rounded to the same approximate frame number. Comparisons involving frame- or seconds-based timecodes, plain values (int/float/str), or differing frame rates are unchanged
• [bugfix] Fix image sequence inputs when using OpenCV 5.0

Packaging

• [general] scenedetect and scenedetect-headless are unchanged: they continue to ship the full program (library + CLI) with opencv-python / opencv-python-headless respectively. Both packages provide the same scenedetect module (install or depend only one)
• [feature] Official Docker images are now published to the GitHub Container Registry with the full CLI, all backends, and external tools (ffmpeg, mkvmerge) included, thanks @​FNGarvin #​537
  • Example usage (process a video in the current directory):

docker run --rm -v "$(pwd):/files" ghcr.io/breakthrough/pyscenedetect -i /files/video.mp4 detect-adaptive split-video -o /files

• [general] The Windows distribution now bundles OpenCV 5.0, PyAV 18, and FFmpeg 8.1.2. The Windows and Docker builds also override Pillow to 12.3.0 for upstream security fixes (moviepy#2553)

General

• [general] Benchmark results are now published on the website (scenedetect.com/benchmarks), including accuracy at default settings and parameter sweep curves for each detector
