Recreating carykh's automatic lip-syncing tool
Entertainment
Introduction
Carrykh, a popular YouTube channel with significantly more subscribers than the author, recently developed a tool to automate lip-sync animation for his avatar. Inspired by this, the author created a program called Magic Video Tool to automatically align slides of a slideshow to a transcript using the program Gentle. This article explains the features of the tool, the process of creating videos with it, and the various components involved in producing videos without traditional video editing software.
In this tool, the annotated transcript, voiceover recording, and slideshow with precise timing are inputted to generate a video. The transcript is cleaned, sent to Gentle for analysis, and a timetable of words and phonemes is produced. Frames for the video are created based on annotations in the transcript, including commands for slides, B-roll footage, and mood changes. Mouth shapes and movements are synchronized with the speech using ffmpeg and image processing. Soundtrack creation involves specifying tags for background music and sound effects, all done without traditional video editing software.
