C201: HOW TO: Comparing Per-Title Encoding Options

Track C – Friday 3 November 
10:30 – 11:15

Per-title encoding techniques customize the encoding ladder to match the encoding complexity of the source, saving bandwidth on easy-to-compress videos and ensuring the quality of more complex footage. This session compares the efficiency, implementation issues, and costs of multiple commercially available and open-source alternatives, like Capella Systems Cambria Encoder, compression optimization from multiple vendors, and the alternatives available using Ffmpeg. Learn what per-title encoding is, how the various options work, and which is the best option for you.

C203: How To: Reducing Latency and Startup Times

Track C – Friday 3 November 
13:45 – 14:45

Low latency and fast startup times are KPIs for most streaming video producers, particularly for live events. Though a series of structured tests that measure startup time, latency, and network overhead, this session documents the results achieved by reducing fragment sizes, using hybrid fragment sizes, adjusting player parameters like first variant retrieved and the number of fragments retrieved before playback starts, opening a persistent connection between player and server, and other experiments. Results will be shown for computer playback as well as tvOS and Roku. Youll learn the most effective strategies for minimizing startup time and latency without swamping your network with additional HTTP requests, and what youll need to do to implement them in your encoding and delivery workflows.
