If you’re creating an AV1 encoding workflow today that emphasises encoding speed and quality, SVT-AV1 should definitely be on your short list. Its two-pass rate control is tested and proven. With the recent launch of version 1.0, SVT-AV1 appears to have caught up with libaom in quality, with very definite performance advantages. In a 2020 report, Moscow State University (MSU) found that SVT-AV1 was four percentage points behind libaom and 25 percentage points behind Aurora1. At the time, SVT-AV1 had several critical deficits, including a two-pass rate control that was incomplete. to create AV1 encoder implementations that deliver excellent video compression across applications in ways that remove computational complexity trade-offs for an ever-growing video delivery marketplace.” Testing published around that time indicated that SVT-AV1 had quite a hill to climb to stand out among other AV1 codecs.įor example, in a comparison published a month later, I found SVT-AV1 to be last among the four AV1 codecs I tested (AOMedia’s libaom, Visionular’s Aurora1, aomenc, and SVT-AV1), although only about 3% less efficient than FFmpeg/libaom-AV1. In August 2020, the Alliance for Open Media (AOMedia) developed a software working group to “use the Scalable Video Technology for AV1 (SVT-AV1) encoder developed by Intel.
