Configuring low data rate adaptive streams

When you configure a group of adaptive streaming files, you produce some files at relatively low data rates. With these files, you have several options to preserve quality, including lowering the resolution, the frame rate or both. Lower resolutions preserve frame quality but can look pixelated when scaled for display. Higher resolutions avoid scaling artifacts, but frame quality can suffer. Dropping the frame rate preserves smoothness, but drops frame quality.

If you click over to the main article, you'll be able to see the same source video encoded at 5 configurations, all to 300 kbps (2pass VBR restricted to 120% of target data rate). These are:

  • 640x480x15 fps
  • 640x480x30 fps
  • 400x300x15 fps
  • 320x240x15 fps
  • 320x240x30 fps

Have a look and see which one looks best, and if you have a strong opinion, let us know via a comment.

Venera Pulsar Review: Quality Control for Adaptive Streaming

Quality control software has been around for a while now; for an overview of the category and quick look at four entrants, check out "Quality Control Roundup: Catch the Mistakes Before They Go Live." Producing files for adaptive streaming throws some new wrinkles into the mix, however, both from a format and a management perspective. One of the first products that attempts to simplify QC for adaptive streams is Venera Technologies' Pulsar, which now can analyze adaptive streams produced for HTTP Live Streaming (HLS) and Smooth Streaming, but not HTTP Dynamic Streaming (HDS). In this review I take a look at Pulsar as a whole, with a focus on these new adaptive streaming-related capabilities.
