Once you have the audio file (usually in MP3 or AC3 format), you don't need to download the entire movie again. You can play it alongside your English-language video file using a versatile media player. Using VLC Media Player (Desktop)
This is the biggest hurdle. A Hollywood movie released in the US might run at 23.976 frames per second (fps). However, the version released in India for television or satellite broadcast (where many Tamil dubs are sourced from) might run at 25 fps (PAL standard). If you download a Tamil audio track meant for a TV broadcast and try to play it with a Blu-ray video rip, the audio will drift out of sync within minutes. The voices will start earlier or later than the lips move. Fixing this requires technical skill with software like MKVToolNix or Audacity, often involving stretching or compressing the audio to match the video frame rate.
