AV1 is a new video Codec takes a very long time to encode but it can reduce file size significantly without any loss of image quality
source file for this video was H265 1350mb after converting to AV1 its 322mb which is less than 25% of the size with no observable loss of quality only downside is it took 18 hours to encode
to play it you can use VLC media player or ffmpeg ffplay
i see you do alot of uploads
these are the scripts i use i made them into a batch file on windows this way i have them in the same folder the batch file the video file and the exe of latest ra1ve and ffmpeg and its a matter of drag and drop , since the encoders are very inefficient performance wise and they dont take all cpu so i have 8 files running together it takes alot of storage space
this is for any resolution
ffmpeg -i %1 -pix_fmt yuv420p %1.y4m
rav1e -v --threads 32 --quantizer 100 --speed 5 --min-keyint 12 --keyint 240 --tile-rows 2 --tile-cols 2 %1.y4m --output %1.ivf
del %1.y4m
and this is for 720p
ffmpeg -i %1 -pix_fmt yuv420p -s 1280x720 %1.y4m
rav1e -v --threads 32 --quantizer 100 --speed 5 --min-keyint 12 --keyint 240 --tile-rows 2 --tile-cols 2 %1.y4m --output %1.ivf
del %1.y4m
average size for 24min video during encoding is
47gb to 65gb 720p
105gb to 125gb 1080p
@Chilled Dithering wont work with AV1. It approaches noise in a different way than most codecs. It will analyze the grain in first pass, denoise it and then apply emulated grain filter on top. However the grain filter is currently kinda... broken. And the main reason to use it would be to avoid banding, which you can do by using 10bit.
@Chilled Aomenc is more efficient as an encoder but performance wise it is still unusable rav1e is alot faster and the quality difference is not something noticeable unless you had to pause two frames and zoom in to see the difference, so for the time being i am sticking to rav1e since in re encoding i lose 0 data to compression of over 50%, when the hardware encoder card that i ordered arrives i think it uses all the features of the aomenc
as for bdmv i dont have the bandwidth to download massive files yet
