A recent consulting project involved computing the VMAF, SSIM, and PSNR scores of 30 fps 480p video encoded from a 60 fps 1080p source file. I’ve not performed measurements like this in the past and assumed that simply converting the 60 fps sources file to 30 fps via the “-r” option would convert from 60…
I’m not going to IBC, but if you are, please check out AV1 hardware encoding acceleration from Socionext. Here’s the blurb from the press release. There will be a demonstration of the world’s first hardware-based implementation of an AV1 encoding system. AV1 is a new, advanced video data compression standard established by theAlliance for Open Media,…
My first look of the AV1 codec is up on Streaming Media Magazine. Here’s the pithy summary. “These tests revealed glimpses of very alluring quality as compared to existing codecs, but at a current encoding cost that’s far beyond what the vast majority of video publishers can afford to pay. How many devices will play…
Number of hours of streaming required to recoup 60-minute encoding cost. Author’s note: The author would like to acknowledge the shocking fact that he is not perfect and that this lack of perfection often reveals itself, quite embarrassingly, in spreadsheet-intensive articles. I did the best I could and checked every number and assumption multiple times, but…
This is the fourth article in a series on saving encoding and delivery costs. The first three articles are: Saving on Encoding and Delivery: Dynamic Packaging Saving on Encoding and Streaming: Deploy Capped CRF Saving on Encoding: Adjust Encoding Configuration to Increase Capacity Cloud encoding is a great alternative for producers who don’t want to…

I’m releasing the 2018 update to my book Learn to Produce Video with FFmpeg in 30 Minutes or Less, and you can download a chapter for free below. It’s Chapter 4 on bitrate control techniques which includes constant bitrate encoding (CBR), variable bitrate encoding (VBR), Constant Rate Factor (CRF), and Capped CRF. As with all chapters,…
This is the third in a five-part series on how to cut your encoding and streaming costs. The first article was on Adjusting Encoding Configurations to Increase Capacity, while the second was on Deploying Capped CRF Encoded videos. You can dramatically reduce net encoding and storage costs by implementing dynamic packaging for your live or VOD…
This is the second in a five-part series on how to cut your encoding and streaming costs. The first article was Saving on Encoding: Adjust Encoding Configuration to Increase Capacity. Article summary: Capped CRF encoding is a single-pass encoding method that can save encoding costs compared to two-pass VBR. Capped CRF is also a simple per-title…
This is the first of five articles on how to cut your encoding and streaming costs. A key focus of my book Video Encoding by the Numbers was to isolate the qualitative impact of critical encoding decisions, particularly when they significantly impact encoding time. For example, if a configuration improves quality by 1%, it likely…
