Websites like Movierulz , Waptrick , and Tamilrockers (in their earliest iterations) gained massive traffic by offering 3GP versions of blockbuster films. A 3-hour Tollywood epic starring Chiranjeevi or Mahesh Babu could be compressed down to a mere 60MB to 100MB. The Massive Trade-off

MP4 is the winner. It offers the best balance for modern Telugu movie fans who want to store 50+ movies on a 32GB phone without sacrificing the visual experience.

A: Use H.264 for the best balance of quality, compatibility, and file size. For 4K content, consider H.265 (HEVC) for even better compression.
