Hello beloved FFMPEG developers!

Recently I found this paper:

Which describes how to get motion vectors from mpeg2 stream and re-use
them when transcoding to mpeg4, as also other information. The time
saved is over 60%.

So my question is currently ffmpeg using any of the mpeg2 information
when transcodign to mpeg4 or it is doing raw encoding?
