Estimated time remaining is incorrect if encode is paused for a while.
I had a queue of several encodes going for a while that I decided to pause while I did some work in Premiere in After Effects. After Effects needed to render something that took 20 hours. When that was done I went back to Media Encoder and continued the encode, but now my "remaining" time says 27 hours remaining. Each job in this queue typically takes about 1-2 hours. So obviously, Media Encoder is not factoring in the time paused for its time remaining calculation. It basically just seems to be this basic calculation:
(CurrentTime - StartTime) / %complete * %left
