Nah, tiles hurt quality. Use Av1an (or Nmkoder on Windows if you want a GUI) with AOM to multithread the encoding by scene for offline encodes.
For livestreaming, SVT-AV1 1.0 is now usable on good CPUs (eg. AMD 5800x+ desktop CPUs, Intel 12600+ desktop CPUs) at higher CPU presets (8+, depending on your CPU and what you're streaming), just currently no one allows for AV1 ingest for livestreams.
- yupyup54133 4y agoThat is not entirely true. Using scene-chunking to multi-thread the encode means that the video buffer can not be transferred between scenes making the start of each scene visually worse in video streaming situations where the bit-rate is capped. For example, a 2Mbps video stream will usually have a 4Mb video cache that can be used to preload data. Having this video cache means that a 2Mbps video stream can burst up to 6Mbps for one second while still maintaining a 2Mbps cap.
