Try specifying the path to VMAF model:

.\av1an.exe -i .\lossless.mkv --target-quality 91  --vmaf-path 'vmaf_v0.6.1.json' -o av1an_loss.mkv

Download the model and put it in the same folder as your video file.

The first encode failed due to

but the next worked (just by re-running it). Thanks.

@AlyoshaVasilieva The latest git version has better error handling, and will tell you the piping error (as well as properly capture the stdout/stderr from ffmpeg in the case of vmaf calculation fail). It also has a --max-tries argument which you can set, which should work for you since you mentioned that resuming worked for you.

Closing as there is nothing to act on anymore, as everything has already been fixed in the git version
