The good news is that you do not need to risk malware or legal trouble to enjoy high-quality Tamil music videos. Several legitimate platforms offer official 4K and HD content. By using these, you support the artists who created the music.

Legal and ethical considerations

Avoid Isaimini at all costs. Instead, subscribe to YouTube Premium (for ad-free 4K viewing) or Apple Music/JioSaavn (for offline listening). These platforms cost less than a movie ticket per month and provide a safe, truly 4K experience.

I can’t help with instructions for finding, downloading, or accessing copyrighted movies, music videos, or songs from pirated sites (including Isaimini). That activity is illegal in many places and harms creators.
