Video Encoding

Video technology has undergone a rapid evolution in the past couple of decades. Earlier, videos were made of large collections of still photos, and they used excessive bulky files to make them digital. But now, video encoding has brought a technological transition — compressing these files to consume less space…

Have you ever heard of Quick Sync Video or NVENC? Maybe CUDA sounds familiar. All of the three are hardware acceleration technologies developed by Intel and Nvidia, respectively. AMD also has its own unique hardware-accelerated video encoding/decoding technique. That was VCE, now evolved into VCN. …

Recently, we have announced the release of the new Elecard CodecWorks 4.8. From this video, you may learn about new features implemented such as hardware encoding on NVIDIA graphics cards, support for popular protocols, and a new web-interface. Watch our new video to see all the major updates. CodecWorks is a professional platform for real-time encoding and transcoding into HEVC/H.265, AVC/H.264 and MPEG-2 video supporting adaptive bitrate streaming via HLS and MPEG-DASH protocols with the best possible quality.

ffmpeg -loop 1 -i <input_image> -i <input_audio> -shortest -acodec copy -pix_fmt yuv420p -y <output_video> Explanation of flags -loop 1 = Enable loop (binary flag 0/1) -shortest = Use the shortest stream to terminate encoding -acodec copy = To copy the audio codec (for faster video encoding, do not re encode…

by Joel Sole, Mariana Afonso, Lukas Krasula, Zhi Li, and Pulkit Tandon — Introducing the banding artifacts detector developed by Netflix aiming at further improving the delivered video quality Banding artifacts can be pretty annoying. But, first of all, you may wonder, what is a banding artifact? Banding artifact? You are at home enjoying a show on your brand-new TV. Great content delivered at excellent…

Last year on 11th May, Amazon launched their first 6th generation EC2 general-purpose instance, a.k.a “Graviton 2”, their next-generation Arm-based chip, utilizing 64-bit Arm Neoverse N1 cores. These processors boast up to 40% overall improvement on cost-performance ratio, compared to similar-sized M5 instances. I’ve been meaning to build a “portable”…

Discrete co(sin) transform at a glance. Main reasons of why is it predominantly used in lossy (video) image compression systems. — Let us recapitulate the main steps of processing a video frame as it is being encoded using a H.265/HEVC system (Fig. 1). At the first step, termed conventionally “block division”, the frame is divided into blocks called CUs (Coding Units). The second step involves predicting the image inside each block…

Getting content to the customer as efficiently as possible On the Showmax tech blog we usually discuss the work of delivering a world class subscription video-on-demand service on the African continent from the engineering perspective. We often use pretty in-depth terms, and some that we even invent ourselves. At times…

Broadcasters, content owners and OTT providers are slowly but surely re-defining their streaming workflows, especially as it relates to real-time streaming. These content providers have been confined to the playback experience within the viewer at the end of the streaming pipeline. …
