I'm pretty active in the av1 community. Most of us who use av1 encode our own from the raw blurays or high quality remuxes. Besides the av1 content on public trackers, I think I saw a group called onlyfaffs and another one called WhiskyJack who were both putting out some av1 content, but imo, their filesizes are too large, so I avoid them if possible.
The other thing to worry about is that most people who use av1 also convert the audio to opus. Fully opensource codecs and all that. The issue is you don't know what bitrate they are using for their conversion. So audio is a concern too when downloading av1 content.
Okay so I just went a private general tracker and looked up an av1 movie. It is a 2014 feature film encoded by the WhiskyJack group (the better trackers don't allow AV1 content yet). For this film, the audio codec is Opus. I looked in the nfo and for the audio file, it says that they are using Opus 5.1 with a 32 bit rate. That's not ideal. For 6-channel audio, we recommend 256 kb/s. 192 is acceptable, but it's going to be another 20 megabytes to bump it up to 256, so why not do it?
Also, it doesn't tell you what the source is. So if the original audio was ac3 or e-ac3, it is not going to sound great.
Bit depth and bit rate are not the same thing.
Yikes. Thanks for catching that. I mistyped.
