JVET-AQ0192 Improvements of NS2 software at 0.2x under CfP conditions [G. Laroche, P. Onno, B. Galmiche, N. Ouedraogo (Canon)]
This informative contribution reports results of a set of modifications of the NS2 software evaluated under the CfP conditions. In particular, the proposed modifications target the 0.2x and 1.0x configurations of the CfP. These modifications include adopted ECM technologies, enhancements to existing NS2 technologies and new added technologies.
When combined, these modifications achieve a YUV BDR improvement of 13% at 0.2x encoder runtime, and almost 20% at 1.0x encoder run time, compared with VTM-24.0 operating at 1.0x encoder runtime.
4 changes: RPR resampling and decision modification provides highest speedup, then temporal prediction of affine, clipping refinements and temporal partition prediction.
