Optimise split & stitch encoding with Bitmovin’s Smart Chunking

Bitmovin has optimised its Next-Generation VOD Encoder with Smart Chunking to further increase the quality and turnaround times of video streaming with split and stitch. The new functionality optimises chunk lengths and bitrate distribution, delivering an improved visual quality throughout the whole asset that is visible to audiences.

According to Bitmovin, Smart Chunking is the next evolution of the split and stitch algorithm, which is when a video file is split into multiple parallel encoding jobs. The split and stitch algorithm accelerates encoding but can cause the quality to drop between segments due to bitrate “jumps”, which can be visible to viewers. 

Smart Chunking intelligently optimises chunk lengths and bitrate distribution, ensuring enhanced visual quality throughout the whole asset. To achieve this, Bitmovin decoupled the chunk duration, which allows for variable chunk size depending on the type of codec and the complexity of encoding, providing users with immediate and visible improvements.

Stefan Lederer, CEO & Co-founder of Bitmovin, said, “Smart Chunking is a new innovation that ensures our customers can encode video files even more efficiently at speed and scale in the highest quality, with absolutely no trade-offs

“It doesn’t matter if you are a broadcaster with millions of viewers or a more nimble streaming service, our Smart Chunking will benefit all users with optimised split and stitch encoding that maximises the viewing experience for audiences while helping our customers achieve their business goals.”Smart Chunking will be on display at booth W10109 at the NAB Show taking place at the Las Vegas Convention Centre from April 16-19.
