You can't choose the Q value for a multipass in CCE. You'll have to use the average bitrate you wish to achieve (this is why you get a correct filesize!)

jorel, for the last time:

RoBa does NOT do CBR, it does a one pass variable bitrate encode. The bitrate varies so that the quality is kept constant, just like CQ in TMPGEnc.

See that section from your log - RoBa is a one-pass variable encode tool but it will do the resizing pass if necessary. That's what we've been trying to tell you all day long.

Regarding the one pass in Q mode, the second in VBR:

I think it's quite safe to do the resizing pass if the filesize difference is not big (I'd estimate 1-5% might be safe). As the vaf file...

Of course you'll get perfect sizes, you're 1) first doing a vaf file creation pass, using the Q value RoBa has predicted and 2) then doing a resize pass using the average bitrate you wish the final...

RoBa _is_ a one-pass variable bitrate method. The Q value is predicted and then used to do a OPV encode. I think that D2S does a second pass...
