Installation

Mementoizer can be installed from PyPI:

pip install mementoizer

Usage

Command-line usage: mementoize <video-filename>

Programmatic usage:

from mementoizer import mementoize

mementoize(video_filename, ...)

Options

--skip-start Number of seconds to ignore for cutting purposes at the beginning of the video file. For example, skipping intro credits. Default: 0

--skip-end Number of seconds to ignore for cutting purposes at the end of the video file. For example, skipping end credits. Default: 0

--min-scene-length Minimum number of seconds to count as a scene. If a cut is detected less than this many seconds after a previous one, it is disregarded. Default: 120 seconds

--threshold Parameter for tuning cut detection. Must be a float between 0 and 1. Typical values for normal shot detection are 0.4-0.6. Since we are trying to detect scene boundaries rather than plain shots, it's set a little higher by default. Default: 0.7

--overlap Number of seconds to overlap between clips (chronologically). You will see this many seconds repeated to connect the previous scene to the one you are watching now. Default: 4

--cuts Manually specify cut times, in seconds after the start of the video. If this is provided, cut detection is skipped. --skip-start, --skip-end, and --min-scene-length are still applied. Values should be comma-separated integers. NOTE: the resulting video will start at the first timestamp you provide. So you must start the list with 0 if you don't want to skip the first scene.

--verbose Print out the cut times detected (or supplied if --cuts is specified).

--dry-run Print detected cut timstamps and exit. Do not write or modify any files.
