Well documented here, I believe:

When encoding: "-level 3".
When decoding: I pass on this question. Neither ffmpeg nor ffprobe tell
_me_ the difference[*], while mediainfo (I know: yuck) does note the
difference in "Format version" ("1" vs. "3.4").

But why would you care? It's just an intermediate format for you,
right. Use the fastest! (I still prefer a filter chain, when possible.
