What is hfpli?
Remove "-c:v h264", it makes no sense (in most command lines),
old documentation always suggested a minimal quantiser of "2"
(instead of "1"), iirc that significantly reduces the filesize.

But you didn't think of providing the console output which
is usually needed if you need support here ;-(

This should not happen: If you accept a sufficiently
high bitrate (which is much closer to h264 than mjpeg),
you should get perfect quality with both vp8 and vp9
(vp8 should be faster).
Concerning your original question, consider using
mpeg1video but if vp8 is acceptable, it should be
able to produce significantly smaller files for a
