Discrepancy Between VTT File Timestamps and Actual Audio Timestamps

The timestamps in VTT files do not always match the actual audio timestamps. This discrepancy varies from video to video and can be off by about 1 second. This issue arises because the timing of the speech in the VTT file is not perfectly synchronized with the actual audio. When editing videos or creating subtitles, it is important to account for this discrepancy and make necessary adjustments.
