This is a critical quality indicator. WEBRip stands for "Web Rip." It means the video was sourced from a streaming service (like Netflix, Amazon Prime, or Hulu) but was captured or "ripped" via a screen recording or a less-than-perfect capture method. While the original source quality is high, the process of ripping it can introduce compression artifacts or a slight drop in image fidelity compared to the original stream.
The .mkv container is popular for its ability to hold multiple audio tracks (e.g., Hindi and English) and subtitle files within a single, smaller file size without compromising video quality. "Repack" generally indicates that the file has been optimized for size. limitless720pwebriphindidubvegamoviestomkv repack
