Just a quick note about the Per-Title Encoding Webinar that I’m producing next Tuesday, August 29th, at 2:00 PM EST. In the webinar, after introducing the concept of per-title encoding, and discussing Netflix’s and YouTube’s technologies, I will compare three per-title approaches:
– Capella Systems’ Source Adaptive Bitrate ladder, as implemented in their Cambria FTC encoder, which you can read about here;
– Capped CRF, an approach used by JWPlayer and other technology providers;
– Brightcove’s Context Aware Encoding (CAE) architecture (image below), which considers content properties, distribution targets, and codec restraints to determine the number of streams in the adaptive group and their configuration. CAE is a programmable, sophisticated technique that I look forward to exploring further.
Brightcove’s Context Aware Encoding architecture.
To test each technology, I will use 15 videos ranging from screencams, to simple and complex animations, to low and high motion real world videos, and actual movie footage. The baseline for all encodes will be this encoding ladder, which I’ll use to set baseline quality levels.
The starting point for our per-title encodes.
Then I’ll deploy each technology, enabling the encoders to boost the data rate by as much as 50%, and deploy as many streams as necessary for the source content, though Brightcove’s CAE is the only technology tested that changes the number and resolution of available streams. I’ll compare the content aware output to the original output to determine the increase and decrease in data rate and quality. I’ll also examine the variability in each stream to determine the potential impact on stream deliverability and quality of experience (QoE).
Lots of work to do before next Tuesday, but I’m excited to see how these technologies compare.
If you’re not considering per-title encoding, you’re already behind the curve. This webinar will introduce you to the concept, and describe multiple approaches that you can implement today to reduce bandwidth and improve viewer QoE.
Details and Registration
The webinar costs $49.99, and you can register here. It’s a bit clunky; first, you’ll have to register with the site, then you’ll have to pay. If you have any problems, please contact me directly at [email protected].
Note that this webinar is the last of six in a series entitled, Rebuild Your Encoding Ladder. If you purchase this webinar, and complete watching the other five, you’ll receive a certificate of completion.
I hope to see you there.
