Thank you all for the suggestions I solved my particular problem the following way

```julia
open(`ffmpeg -f rawvideo -pix_fmt gray -s:v 5120x5120 -r 70 -i pipe:0 test.mkv`, "w") do out
    for frame in video
        img = convert(Image{Gray{U8}}, frame)
        write(out, reinterpret(UInt8, data(img)))
    end
end

```

It is not terrible performant but it get’s the job done for now.
