Muxing AV1 .ivf into .mp4

What are folks using to mux a AV1 .ivf elementary stream into .mp4? Good old mp4box nightly builds? Any particular parameters?

IIRC I tried this and it works fine, but I don't do AV1 encoding on the regular

Using the default mp4box.exe -add foo.ivf foo.mp4 syntax, the resulting file looks correct in MediaInfo and plays in VLC and the Windows "Movies & TV" player. But it won't open in any of the Adobe Creative Suite apps, even though I have a HW AV1 decoder in my GPU.

I was hoping the new DirectX-based After Effects and Premiere would support generic DirectShow file decoding as it had in years past.
