This is the first in a series of posts detailing what you need to know to create the perfect encoding ladder. It’s a high-level introductory series good for streaming novices, but too basic for most experienced streaming producers. This article details how to choose the best codec for streaming video. What’s a codec? A compression technology that shrinks your video …

ASICs have an unfair (and inaccurate) reputation for being obsolete the day they leave the foundry. However, while some functions are baked into the hardware, firmware, and driver software enable continual upgrades in both features and performance. To explore these capabilities, I spoke with two members of the NETINT development team, Neil Gunn, who is NETINT’s Video Firmware Tech Lead, …

The Bitmovin Video Developer Report, now in its 6th edition, is one of the most far-reaching and useful documents available to streaming professionals (now with no registration required). It’s a report that I happily download each December and generally refer to frequently during the next twelve months. Like the proverbial elephant, what you find important in the report depends upon …

The thing about FFmpeg is that there are almost always multiple ways to accomplish the same basic function. In this post, we look at four approaches to scaling. We found that if you’re scaling using the default -s function (-s 1280×720), you’re leaving a bit of quality on the table as compared to other methods. How much depends upon the …

Learning how to build an encoding ladder is one of the most fundamental tasks for a streaming media professional. It’s astounding how much you need to know to get it right. By way of background, the original encoding ladder used by most professionals was from Apple Tech Note TN2224, long since replaced by Apple’s HLS Authoring Specifications. This H.264-only ladder …

Even in 2023, many high-volume streaming producers continue to rely on software-based transcoding, despite the clear CAPEX, OPEX, and environmental benefits of ASIC-based transcoding. At least part of this inertia relates to outdated concerns about the shortcomings of ASICs, including sub-par quality and lack of upgradeability. As a parent, I long ago concluded that there were no words that could …

For some reason I can’t explain, Molly Brown’s comment from the movie Titanic, “there’s something you don’t see every day,” (while watching the doomed ship sink), has stuck with me since I saw the movie back in 1997. It recently came to mind when a colleague informed me that HEVC support had eclipsed AV1 on the CanIUse website. You see …

One of the most power-hungry processes performed in data centers is software-based live transcoding, which can be performed much more efficiently with ASIC-based transcoders. With power costs soaring and carbon emissions an ever-increasing concern, data centers that perform high-volume live transcoding should strongly consider switching to ASIC-based transcoders like the NETINT T408. To assist in this transition, NETINT recently published …
