SVT-AV1 Encoding Bitrate Estimation Using Motion Search Information

no code implementations8 Jul 2024 Lena Eichermüller, Gaurang Chaudhari, Ioannis Katsavounidis, Zhijun Lei, Hassene Tmar, Christian Herglotz, André Kaup

Enabling high compression efficiency while keeping encoding energy consumption at a low level, requires prioritization of which videos need more sophisticated encoding techniques.

Encoding Time and Energy Model for SVT-AV1 based on Video Complexity

no code implementations29 Jan 2024 Lena Eichermüller, Gaurang Chaudhari, Ioannis Katsavounidis, Zhijun Lei, Hassene Tmar, Christian Herglotz, André Kaup

We propose an encoding time and energy model for SVT-AV1 based on empirical relations between the encoding time and video parameters as well as encoder configurations.

Encoder Complexity Control in SVT-AV1 by Speed-Adaptive Preset Switching

1 code implementation11 Jul 2023 Lena Eichermüller, Gaurang Chaudhari, Ioannis Katsavounidis, Zhijun Lei, Hassene Tmar, André Kaup, Christian Herglotz

Current developments in video encoding technology lead to continuously improving compression performance but at the expense of increasingly higher computational demands.

The Bjøntegaard Bible -- Why your Way of Comparing Video Codecs May Be Wrong

1 code implementation25 Apr 2023 Christian Herglotz, Hannah Och, Anna Meyer, Geetha Ramasubbu, Lena Eichermüller, Matthias Kränzler, Fabian Brand, Kristian Fischer, Dat Thanh Nguyen, Andy Regensky, André Kaup

Using additional supporting points inbetween standard points defined by parameters such as the quantization parameter, we assess the interpolation error of the Bj{\o}ntegaard-Delta (BD) calculus and its impact on the final BD value.
