Current encoders aren't focused on lossless performance(and I hope they won't waste much effort on it), and the AV1 standard has some limitations that make it limiting for lossless. Makes no sense to get an A380 at all if you want to encode stuff to AV1 for storing it. 0). Then the CPU can piece together the analysis of what superblocks+blocks should be preserved at the given quality level. y4m -c:v libaom-av1 -b:v 500k -strict experimental netflix720p500AV1. 3.

Most of them are optimized for real-time encoding, so probably faster than SVT-AV1 but likely not as efficient at compression or quality. This is due to x265 encoding being used as it is one of the few codecs that enjoys widespread hardware support at this resolution. My project is based on Go and the current codec that I am using is libx264. Members Online AnemographicSerial -hwaccel tells ffmpeg to enable the specified hardware decoders, and -c:v av1_qsv as in the encoder settings, specifies which hardware decoder to use.
