I used open-source video test sequences so that others can reproduce the results I got.I am sure that once the LCEVC standard is released and encoder implementations enter the market, you’ll see more codec comparisons like the one presented here with different sequences, tuning parameters, presets, etc.And, consequently, every codec comparison has its own idiosyncracies. Encoders are complex and come with several tuning parameters designed to help you compress video to your liking and requirements.They agreed, and within a week, I started encoding using V-Nova’s LCEVC encoder and analyzing the results for myself.īefore we proceed with the codec evaluation, I’d like to highlight a few points. I got in touch with V-Nova ( Fabio Murra, Anthony Concannon) and asked them if I can get my hands on some test software to run experiments and see the performance of LCEVC for myself. How LCEVC Works Background to this articleĪfter writing an article on the LCEVC standard, I wanted to test it and see the results for myself. More details can be found in our comprehensive guide to LCEVC and at. Here is a diagrammatic representation of how LCEVC works. This fallback mechanism ensures backward-compatibility and encourages roll-out of the LCEVC codec without the fear of breaking the user’s experience.
If the decoder/end-device supports LCEVC, the enhancement layers are decoded, else, the base codec alone is used to decode the bitstream and the video is rendered to the user. along with an enhancement layer that can be used to improve the quality of the video. The LCEVC codec’s output is a combination of a “base bitstream” produced by a video codec such as AVC, HEVC, VP9, AV1, etc. CBR using an IPPP Structure (no B-pictures)Īs described in our comprehensive guide to LCEVC, the LCEVC codec (Low Complexity Enhancement Video Coding) is “a codec to improve other codecs” with a low complexity-overhead.
