Hi, @tungs I had recorded canvas using timecut. But result was not full video, one half of video is blank, And it started to play after some time. How to sync video start time with this module?

Hi @JenishaDalin, could you post a simplest example of the web page you're trying to capture, the command you're trying to use, and a screenshot of the half-blank video? It's very hard to understand what the issue is with the information you've provided.
