PyJianYingDraft
pyJianYingDraft is a Python library used to programmatically generate and manipulate video project files compatible with CapCut and Jianying editors. It functions as an automation tool for creating video editing drafts, allowing users to assemble montage pipelines through code.
The project enables the creation of video drafts by replacing media assets and updating text within existing project templates. It provides a programmatic interface to manage dynamic video templates, which preserves original formatting and timing while swapping specific materials.
Capabilities include the management of multi-track layering for audio, video, and text, as well as the application of visual effects and transitions. The library handles complex production details such as animation keyframing, media trimming, video masking, and the conversion of external subtitle files into timed on-screen segments.
