Why do I need this tool?
After recording in the '1. Recorder', you might edit your reaction video in software like Premiere Pro or CapCut to add intros, outros, or cuts. This editing changes the video's timing, breaking the original 'Sync Map'.
This edited video should be uploaded to YouTube as 'Unlisted'. On its own, this unlisted video is "incomplete" as it doesn't appear in YouTube's public search.
However, when you bring that 'Unlisted' link here and re-sync it, it becomes "complete" within our system. This allows viewers to watch your reaction perfectly synced with the original content via a VE URL, and you can monetize the views generated by your unlisted video.
The 'Timeline Editor' is the essential tool to re-sync your 'Unlisted' video with the now-broken 'Sync Map'.
