Test `save-qp` command but using a shifted start time.

Test `split-video` command using ffmpeg.

Test `split-video` command using mkvmerge.

Validate processed frames without start time being set. End time is the end frame to stop at, but with duration, we stop at start + duration - 1.

Validate frame number/timecode alignment at the end of the video. The end timecode includes presentation time and therefore should represent the f

Validate frames that are processed when crossing a scene boundary. End time is the end frame to stop at, but with duration, we stop at start + dur

Validate processed frames with both start and end/duration set. End time is the end frame to stop at, but with duration, we stop at start + durati

Validate behavior of setting parameters via the `time` command.

`FrameTimecode` comparison operators should accept a bare :class:`Timecode` operand.

Test that backend handles video with corrupt frame gracefully with defaults.

detect-threshold cut frames must be backend-deterministic across PyAV/OpenCV/MoviePy. Regression coverage for the changelog item: previously the

Test SceneManager detect_scenes method with a callback function. Note that the API signature of the callback will undergo breaking changes in v1.

Test SceneManager detect_scenes method with a callback function and a detector which requires frame buffering. Note that the API signature of

Test passing StatsManager to a SceneManager and using it for storing the frame metrics from a ContentDetector.

Test all detectors functionality with a StatsManager.

`equal_framerate()` is the soft-deprecated alias for `equal_frame_rate()` (issue #548). Both forms should produce identical results for every acce

Test FrameTimecode equality (==, __eq__) operator.

Clip containing fades in/out.

Per migration guide, `frame_num`, `frame_rate`, and the legacy `framerate` alias are read-only properties; callers must construct a new FrameTimec

For Timecode-backed instances, frame_rate is the approximation passed via fps.

`frame_rate` returns an exact Fraction; `framerate` returns the float equivalent.

End-to-end: passing a float NTSC rate into the FrameTimecode constructor must yield the exact Fraction representation, not the lossy float. This i

Test FrameTimecode constructor argument "fps".

`framerate=` is the soft-deprecated alias for `frame_rate=` (issue #548). All backends must accept both forms and produce the same `frame_rate`.

Non-NTSC, non-integer framerates should fall back to limit_denominator and not be misclassified as NTSC.

Test FrameTimecode get_frames() method.

Test SceneManager `get_scene_list()` method with the `start_in_scene` flag.

Test FrameTimecode get_seconds() method.

Test FrameTimecode get_timecode() method.

Test FrameTimecode values, when used in init return the same values

Path to a short image sequence (from counter.mp4).

All backends must open videos at non-ASCII filesystem paths. This is a silent failure mode on platforms with mbcs default codecs; the failure mode

Ensure correct exception is thrown if the path does not exist.

Ensures the function exists and is callable without throwing an exception.

Test loading a corrupted stats file created by outputting data in the wrong format.

Test loading an empty stats file, ensuring it results in no errors.

Test loading a stats file with some hard-coded data generated by this test case.

[Windows Only] Ensures that a command string too large to be handled is translated to the correct exception for error handling.

Test StatsManager metric registration/setting/getting with a set of pre-defined key-value pairs (metric_dict).

Detectors accept min_scene_len as int (frames), float (seconds), or str (timecode).

Detector ``min_scene_len`` and FlashFilter ``length`` should accept any TimecodeLike, including :class:`FrameTimecode` / :class:`Timecode`.

Movie clip containing fast cuts.

Common NTSC framerates should be detected from float values.

NTSC detection should work for any base rate, not a hardcoded list (e.g. 48000/1001 for HFR cinema).

Low-precision float reports (e.g. truncated to 3 decimals) should still snap to the NTSC rational.

Test opening an image sequence. Currently, only VideoStreamCv2 supports this.

Test rounding and precision, which has implications for rounding behavior.

Validate video properties: frame size, frame rate, duration, aspect ratio, etc.

Rational framerates should round-trip frame/second conversions without drift.

Validate basic `read` functionality.

Ensure calling `read()` handles the end of the video correctly.

Validate invoking `read` with `decode` set to False.

Test `reset()` functions as expected.

Test scenedetect.scene_manager.save_images function.
