Expected duration: 1 day or less I require assistance removing the auto-generated watermark from a downloaded TikTok video file while precisely resynchronizing its audio track. The task involves accessing only the standalone video file locally, as the original TikTok URL is no longer accessible. Using professional video editing software skills, the watermark must be carefully erased from the lower right corner without affecting the overall video quality. Additionally, the audio will need subtle adjustments to perfectly match the visuals, as downloading may have slightly disrupted their alignment.
