Learn to use Capped CRF with SVT-AV1 and FFmpeg for live transcoding, including how capped CRF compares to VBR and CBR. All tests and results are available in downloadable PDF. Capped CRF is an alternative to VBR and CBR that saves bandwidth on easy-to-encode sequences and preserves quality on hard-to-encode sequences. Our tests with SVT-AV1 and FFmpeg show: Performance: Capped …

There are four bitrate control techniques worth considering for live encoding/transcoding using the SVT-AV1 codec. These are: Capped CRF VBR Capped VBR Constrained VBR Here’s what I found: Overall: Capped CRF shows promise with significant bitrate savings, good quality retention, and the best overall performance by ~10 – 25% (meaning more streams from the same hardware). VBR was generally the …

A recent review from The Ohio State University’s Derrick Freeman highlighted what he learned from Streaming Media 101. Below is his review, which I’ve chopped up into bullet points. “I just recently earned my certificate from Jan Ozer’s “Streaming Media 101: Technical Onboarding for Streaming Media Professionals” e-learning course at Streaming Learning Center. I was amazed at how much I …
