MainConcept® maintains the largest codec video and audio library on the planet, and it can empower almost any use case and digital video workflow. However, not every company has the expertise needed to integrate and tune codecs to get the most out of them. Moreover, codecs are only one part of the equation—there is also the challenge of multiplexing and containers. This is why we developed the MainConcept Transcoding SDK—to simplify the adoption of codecs into digital video workflows. And, today, we released our latest version!
Encoding Time on Apple Computers: The M1 Revolution
Apple computers have a prolific history in video editing, having long been the choice of professionals and hobbyists. When Apple switched to Intel processors in 2006, image processing and video editing on macOS became even more popular, creating a demand for professional solutions for video production. In the beginning, Apple Final Cut Pro was the most commonly used professional Non-Linear Editing (NLE) solution, but slowly other companies, such as Adobe, Autodesk, Magix, Corel and Blackmagic, introduced their video-editing software products. Today there are dozens of choices from companies actively releasing new features and updates to make video editing on macOS a smooth experience, allowing for the creation of everything from quirky TikTok videos by hobbyists to award-winning movie masterpieces by production houses and studios.
LCEVC – increasing compression efficiency, lowering costs and reducing carbon footprint
We spoke with Guido Meardi, CEO and Co-Founder of V-Nova to understand the benefits of LCEVC video compression and what these could mean for users across Broadcast, Media & Entertainment.
The evolution of a regional TV and advertising system
This narrative begins in 2006. One of the more forward-thinking European broadcasters began the search for a system to take their single national feed, that was funded through traditional ad break advertising, and produce just over 30 variants of this channel. Every channel (regional feed) would now include some regional advertising content, replacing the national advertising breaks at specific times of the day. Starfish Technologies was awarded the contract to design and supply this system. It was implemented using SDI based technology located at each of the regional distribution hubs, the majority of which were unmanned. This system worked well and generated a significant additional revenue stream, so the broadcaster requested an ‘upgrade’ to this system that would also enable local news bulletins and late changing schedules to be inserted into every regional feed. These requirements were best implemented by moving to a centralised architecture and building a complete regional channel system located at its main transmission centre. The first centralised Starfish Technologies system went live in 2009 and again proved reliable, commercially rewarding and with the significant benefit of providing viewers with locally relevant news content.
Accelerating the Move to Remote & Virtualised Workflows
Over the last three decades, we’ve seen a shift from specialised units for various video and audio functions, to high performance hardware platforms which can be repurposed on-the-fly to support any AV processing, and now to virtualized media applications and microservices which can be spun up and deployed (and paid for) only when you need them.

Universal File Ingest For Digital Video
In the media industry, conversations usually center on encoding, streaming, packaging and low latency. Put another way, it is all about delivering superior visual quality and high-fidelity audio with better compression. Amidst all the discussions on digital video workflows, file ingest is often ignored. For example, when is the last time anyone compared different file ingest tools? It is safe to say that file ingest is one of the most undervalued steps in video production workflows today.
Why “Not-compressing” simply doesn’t make sense?
Imagine a sponge or rather thousands of sponges to be transported over several kilometers. It would require several trucks to store and transport them all!
Let’s take all those sponges and squeeze them. If you look closely at the sponge, you will see that it has lots of holes in it, filled with air. When you squeeze it, you remove the air which is useless and the entire sponge takes up less space.
JPEG XS … What does it mean ?
Over the last 20 years, the number of shared images and videos has considerably increased. In terms of resolution, we have moved from SD, HD to 4K – even 8K – and this is not about to stop. Higher frame rates, higher resolutions, more precision and higher dynamic range (HDR) imply a considerable increase in the amount of data to be transported on our networks. Bandwidth and storage are getting cheaper but this does not compensate the drastic increase of data to be transported or stored. Compression is therefore more than ever a fundamental step in distributing your video over the internet.
Understand the concept of bpp and Mbps to define your compressed data rate!
Every color pixel in a digital image is created through some combination of the three primary colors: red, green, and blue. Each primary color is often referred to as a “color channel” or “color component”, and has a range of intensity values specified by its bit depth. The bit depth for each primary color is termed the “number of bits per channel”, typically ranging from 8 to 16bits. The “bits per pixel” (bpp) refers to the sum of the “number of bits per color channel” i.e. the total number of bits required to code the color information of the pixel.
An uncompressed RGB image with a bit depth of 8 bits per color will have 24 bpp or 24 bits per pixels (8 bits for the Red, 8 bits for the Green, 8 bits for the Blue)
