vapoursynth-zscene 0.5.0

Scene change detection for Vaopursynth

Brought to you by Flawless Media - Digitizing and Restoration

Zscene

ReadScene

core.zscene.ReadScenes(path=string, format=int)

Reads scene data from a given file. Adds the pertinent _SceneChangePrev and _SceneChangeNext properties to each frame.

Supported Formats

Format	Format Code	Description
JSON	0	JSON files produced by av-scenechange. The JSON must have the scene_changes and frame_count fields.
QP File	1	Text files with frame numbers listed on new lines. Often used with x264 or x265 and their --qpfile parameters. Scenes will be marked as scene changes if they have a K or I (but not i) frame type, or if the frame type is omitted completely.

Feel free to open an issue to request scene file formats.

Examples:

• Av Scene Change JSON
• QP File
• QP File - with no frame types

Scene File Generation

Scene data can be generated using something like the following:

vspipe -c y4m source.vpy - | av-scenechange -o scenes.json -

Note that av-scenechange can be built with Vapoursynth and FFMPEG support built in, so there are a variety of ways that it can be fed with video data. Choose what works best for you.
