Default choice of codec and file container for smooth reverse play

Hi,
I hope this is the right forum for my question, please let me know if this not the case.

I am wondering if anyone might be able to suggest an appropriate codec that will allow me to play video smoothly in both foward and reverse directions. I am aware that MJPEG can do this but i am trying to find a codec with a smaller file size. My understanding is that for interframe coding only the differences between non-keyframes are desribed as mathematical operations. I assume that taking the inverse of these operations is compuationally slow and therefore this is why reverse playback is slow.

1. One possible solution is that the codec stores the inverse mathermatical operation....
2. Another possible solution is finding a file container that supports seperate video streams, one that is accessed when forward play is required and secondary stream for reverse play. The size of this file will still be smaller than mjpeg.

Do implementations of either of these exist?
