Per-title encoding is the generic name for any technology or feature that customizes the encod- ing ladder of each encoded file to produce the
best possible mix of quality and bandwidth efficiency.
Per-title encoding is a feature so important that you
shouldn’t choose a new encoder or encoding platform
that doesn’t have it or have it coming.
We took two hard looks at competitive technologies
in 2017, from which we draw most of the observations
contained herein. The first was the article “One Title
at a Time: Comparing Per-Title Video Encoding Options” ( go2sm.com/pertitle). The second was a presentation at Streaming Media West that you can watch at
This article presents a list of features and operating
characteristics to consider when choosing per-title
functionality. It concludes with some items to consider when testing any of these technologies.
Technologies and Deployment Models
Per-title technologies come from multiple sources,
so job number 1 is identifying a source that matches
your encoding workflow. Those who want to acquire
per-title encoding with a standalone encoder should
consider Capella Systems’ Cambria encoder, which
includes a source-adaptive bitrate ladder feature (re-
viewed at go2sm.com/cambria). Harmonic also offers
the EyeQ content-aware compression ladder on a num-
ber of products.
If you’re encoding in the cloud, per-title encoding is
available from Brightcove (context-aware encoding),
Bitmovin (per-title adaptation), and Microsoft’s Azure
platform. You can license encoding technology to incor-
porate into your own encoding stack from FASTech (in-
telligent content-adaptive video compression), Beamr
(content-adaptive bitrate technology), or EuclidIQ (con-
tent-adaptive encoding). Or, you can implement your
own per-title encoding function by deploying an encod-
ing technique called capped constant rate factor (CRF),
which is used by online video platforms like JW Player.
These are all the technologies we knew about when
we wrote this article. If we didn’t mention your tech-
nology, we apologize; please contact the author and

Once you’ve identified the relevant candidates, here
are the factors to consider when comparing them.
If you’re not already using per-title encoding, it’s time.
Here’s a guide to choosing the tool that’s best for you.
