2-Pass Video Encoding

2-Pass Video Encoding is a technique used to optimize video compression and improve video quality. It involves a two-step process that analyzes the video content and adjusts the encoding parameters accordingly.

In the first pass, the video is analyzed to gather information about its complexity, motion, and other characteristics. This data is then used to create a statistical model of the video, which helps in determining the optimal bitrate for each frame.

The second pass involves the actual encoding of the video. The previously generated statistical model is utilized to allocate bits efficiently, ensuring that the video quality is maintained while minimizing file size. This process results in a more efficient compression and better overall video quality.

2-Pass Video Encoding is particularly useful when encoding videos with limited bandwidth or storage constraints. It allows for better control over the compression process and ensures that the video retains its visual integrity even at lower bitrates.
