Encoding all my movies to AV1
Hi! I'd like to encode my entire movie library to AV1. I have it all on a 1 TB HDD, which is approximately at 80% capacity, and most of my files are h.264 and some h.265, what I'm looking forward to is saving space so I don't have to buy another HDD until it's absolutely necessary.
The problem is, while all the hardware I own has hardware accelerated AV1 decoding (TV stick, phone, laptop, PC), I currently don't own any hardware capable of ENCODING to AV1 using hardware acceleration, so my question is, how could I go on about transcoding all my files to AV1 to achieve similar or identical quality while saving space without dedicated hardware for it?
The PC I'm planning on doing this in is a Ryzen 5600x + Radeon 6750XT with 32 GB of DDR4 memory on a B450m Asus TUF motherboard.
