Short Video Performance Evaluation of AV1 Coding Tools

Short videos, ranging from a few seconds to a few minutes, have become popular in many video production. So we need efficient coding tools to compress these videos. AV1 is an emerging open-source and royalty-free video compression format jointly developed and finalized in early 2018 by the Alliance for Open Media. Many coding tools are introduced into AV1 to improve compression performance. However, some coding tools may lead to performance loss to encode these short videos. This paper presents a coding tools performance evaluation of AV1 on short videos. We design an Off experiment by turning off a single coding tool, and the anchor is AV1 with all coding tools on. We list the impact of each open and closed coding tool on the overall performance of the short video.
