The encoders set some parameters for quicker first pass (I knew that), but what I didn't know that ffmpeg doesn't set fast_pskip=1 and ref=1 while mencoder does. > AFAIU you need to use identical codec options in both passes, and it > seems you're not doing that. That _may_ be the cause for your > observations. In fact, it is. I compared the achieved quality after changing the two mentioned parameters and it looks almost the same now. So marking as SOLVED.
