It appears our SVT implementation (which I didn't write) can only handle single image, YUV420 encodes. I'm not sure exactly why:

@jonsneyers Can you offer any insight to @novomesk ?

Image sequences should be fine. SVT itself is limited to YUV420 though, afaik (cannot do YUV444).

avifenc -y 420 -c svt -o animationtest.avif input1.jpg input2.jpg produced the same error.
