No, there is no such way. Every video operation with ffmpeg involves demuxing and muxing. And every muxer - so also ffmpeg's - has more or less subtle differences. ffmpeg may be less efficient (therefore the larger size), have other presents, and so on. Furthermore, your first operation may also lose metadata or data streams, which your second operation cannot recover.
