Executive Summary: B-frames increase compression efficiency, particularly at lower bitrates. However, not all video encoders deliver the requested number of B-frames when encoding using default parameters. Telestream Switch is a software program that identifies B-frames in encoded streams, and computes the overall B-frame percentage. Compressionists seeking the most efficient streams should acquire Switch and test their streams. If B-frames are …

On Wednesday, February 3rd, 2016, Technicolor issued a press release stating that the company had decided to “license its HEVC IP portfolio directly to device manufacturers rather than through the HEVC Advance patent pool.” The release fu

Joicaster is a web-based live streaming syndication platform that takes a single live stream and pushes it out to multiple services, including YouTube Live, Ustream, and Twitch, as well as commercial sites. Joicaster is affordable, straightforward to

On January 13th, 2016, I launched a survey to determine the bitrate control techniques most commonly used by streaming producers. Some preliminary results are in, but the number of respondents is too small to draw any conclusions. I wanted to publish the data to stimulate additional interest, and also announce that I am sweetening the pot with a $100 Amazon gift …

Let’s face it. For-profit enterprises post videos, hold webinars, and produce virtual events to drive sales. How effective are these mediums for that purpose? There’s lots of positive anecdotal evidence, but where are the hard numbers?

The Netflix blog post entitled Per-Title Encode Optimization boldly declares that “to deliver the best quality video to our members, each title should receive a unique bitrate ladder, tailored to its specific complexity characteristics.”

Late last year I ran a survey asking respondents to choose whether DASH or HLS was the best ABR format going forward. The poll results are in and are shown below. Basically, a small majority preferred DASH over HLS. The reasons why are even more illuminating, and are presented below the survey results. “Not sure why i wouldnt cover both …

The recommended bit rate control technique for VOD files produced for adaptive streaming is one of the most fundamental decisions encoding professionals make, but in my view also one of the most confusing. If you scan the white papers on the topic, most recommend using constant bit rate (CBR) encoding to simplify the stream selection process. On the other hand, …

The great migration from Flash to HTML5 is underway. For many producers, this means a switch from RTMP or HTTP Dynamic Streaming to a more HTML5-friendly format. Typically the choice comes down to either HLS or DASH. To help tease out the pros and co
