| Summary: An AV1 decoder/encoder for video streams | |
The Scalable Video Technology for AV1 (SVT-AV1 Encoder and Decoder) is an AV1-compliant encoder/decoder library core. The SVT-AV1 encoder development is a work-in-progress targeting performance levels applicable to both VOD and Live encoding / transcoding video applications. The SVT-AV1 decoder implementation is targeting future codec research activities.

~4% improvement in speed and VBR gaining ~15%.
