Here’s the class description; download link below. With the speed of technology today, one of the most important parts of software is adaptability. By taking control of your own encoding and packaging, you can greatly reduce cost and maintain high adaptability and agility to meet your needs now and in the future. When working with…
DetailsThe video below shows two tools that I’ve installed on every computer that will run them; MediaInfo on all Windows, Linux, and Mac workstations, and Bitrate Viewer, which is Windows only. If you don’t know about these tools, you’ll find the seven-minute video very, very useful. As a preview, MediaInfo provides information about my H.264,…
DetailsI just finished my Produce Videos with FFmpeg course which I recorded with Camtasia, edited in Adobe Premiere Pro, and output in the Adobe Media Encoder (AME). I outputted from AME at about 10 Mbps to ensure quality, but now I’m left with 3 GB of files to upload. I know the data rate is…
DetailsJust a quick note to let you know that I’m launching a video course entitled, Produce Videos with FFmpeg: The Beginner’s Course. The course costs $29.95 and includes 32 video lessons totaling about 3 hours of video with downloadable PDFs of the content covered. Students will learn basics like how to configure video resolution and…
DetailsA couple of additional data points on AV1 encoding as follow-ups to my Streaming Media article here. First, a colleague asked about 4K encoding times on Twitter. Second, a reader recommended using the row-mt switch for VP9. So, I encoded a ten-second 4K test file on the same single-CPU ZBook as the Streaming Media article.…
DetailsSorry for the visual but couldn’t resist. Just got the following email from Unified Patents. All the normal caveats apply; I haven’t reviewed the filings (and won’t) and Unified may not succeed though they’ve had some recent successes. Why the hate on Velos? In contrast to the transparency with which MPEG LA and HEVC Advanced…
DetailsI frequently use the VMAF quality metric to analyze encoding parameters and compare codecs. In my experience, VMAF scores tend to match my own subjective quality observations and the fact that Netflix uses it gives the metric great credibility. Originally, there was only one VMAF version, but Netflix has added both a 4K model and…
DetailsI’m writing a blog post on a free Netflix utility called VMAF-Master that you can download here (Windows executable here). Basically, it’s an open-source command line utility for computing VMAF, PSNR, SSIM, and MS SSIM on Linux and Mac computers with some enterprising contributors compiling a Windows version. One very well written help file relates…
DetailsAccording to the last published statistics, in June 2017, Whatsapp users sent over 1 billion video messages a day. This obviously represents only a fraction of the market and daily traffic has certainly has grown since then. At the same time, 4K cameras have become standard and mobile screen resolutions have increased in size and…
DetailsI recently finished a streaming consulting project with AMC Networks and was pleased to receive the following LinkedIn recommendation from their VP of Video Products. It was great working with Greg and his team with the gorgeous content from AMC. Beyond this work with AMC, I’ve helped media companies and video publishers fine-tune their encoding…
DetailsI just finished a project that involved encoding lots of downloaded YUV test files, which is something I never tried before. The problem is that there’s no resolution or frame rate information in the file header, so you have to detail all this in the command string. My first crack at the problem evolved into this…
