The best open source video and image compression algorithms have improved significantly over the past year, and developer tools have miraculously kept up with this rapid pace. There has never been a better time for video.
Comparing video encoders involves using synthetic metrics to assess visual quality, helping generate data that can be visualized. Plotting encoder performance in different ways helps determine the best encoder for specific implementation needs.
SVT-AV1-PSY, a community fork of the SVT-AV1 video encoder, was created to enhance perceptual quality and ease of use for AV1 encoding. I co-created and currently maintain the project. Our new goal is to merge our features into SVT-AV1.
How tiny can very tiny banner images get?
Writing a fast and simple QOI encoder; illustrated with code examples, a spec breakdown, and step by step implementation instructions.
Comparing the efficacy of various lossless data compression algorithms on text data, comparing time to compress vs output size. The algorithms tested include ZIP, 7-zip, XZ, Brotli, Zstandard, and zpaq.
A brand new JPEG implementation from Google – called jpegli – supports the use of a perceptual colorspace to improve compression efficiency. How does it fare against other codecs, like WebP and AVIF?
JPEG is old, but a new perceptually optimized encoder just became available from Google called jpegli. Like the mozjpeg encoder aimed to outperform older JPEG implementations, jpegli aims to push the format to its limits in terms of compression efficiency.
This article compares Nvidia's NVENC encoder to Intel's QSV encoder for AV1, as well as for other codecs. Who will win?
A collection of the images I used for the blog post published on the same day as this one, lossily compressed with JPEG XL. All images are licensed under CC BY-SA 4.0.
The current debate surrounding AVIF versus JPEG XL needs some third-party quantitative data to support arguments on either side. I've compiled a dataset of 27 high-resolution photographic images to compare performance across them all at a wide fidelity range.
Let's compare browser performance across a variety of architectures, operating systems, and browsers. Which browser is the most performant?
In this test, we will compare the latest Aviator release to the latest Handbrake release in terms of visual quality per bit.
Aviator aims to enable simple, accessible AV1 encoding for everyone with a GUI powered by a fast AV1 encoder.
rAV1ator, a powerful AV1 encoding GUI, sees its 1.0 release.
