Abstract: We introduce an open source Tensorflow implementation of the Deep VideoCompression (DVC) method in this technical report. DVC is the first end-to-endoptimized learned video compression method, achieving better MS-SSIMperformance than the Low-Delay P (LDP) very fast setting of x265 and comparablePSNR performance with x265 (LDP very fast). At the time of writing this report,several learned video compression methods are superior to DVC, but currentlynone of them provides open source codes. We hope that our OpenDVC codes areable to provide a useful model for further development, and facilitate futureresearches on learned video compression. Different from the original DVC, whichis only optimized for PSNR, we release not only the PSNR-optimizedre-implementation, denoted by OpenDVC (PSNR), but also the MS-SSIM-optimizedmodel OpenDVC (MS-SSIM). Our OpenDVC (MS-SSIM) model provides a more convincingbaseline for MS-SSIM optimized methods, which can only compare with the PSNRoptimized DVC in the past. The OpenDVC source codes and pre-trained models arepublicly released at this https URL.
