Never use "calc bitrate as max" with D2SRoBa

[DDogg]

I did a fresh installation last night and found to my horror that "calc bitrate as max" is checked by default in the CCE encoder tab when One Pass Vbr is selected. This is a stupid legacy feature that I am told I actually caused several years ago and it should have been removed. NEVER use it with D2SRoBa. In fact never use it period. Hopefully tylo is checking for it, but I am not sure. If he is not, it would explain several reports about strange sizings I have seen. Again, never use this option, never...never..Ok? :)

thankyou for the info :)

Ok :)

I'm also unchecking it when encoding in OPV without D2SRoBa, but not sure if in this case...
DDogg, could you elaborate a little bit on this?

I'm not even sure I remember anymore what it does. Seems like we were messing around trying to use OPV because it was so much faster (Most people were on 400s at the time). We were using Q 5? and using the predicted average bitrate as the MAX (I think). It seemed to work, but then in retrospect we realize this was just a close equivalent to CBR and the whole thing was abandoned as silly. It was :o

You can imagine what happens now if that stupid checkmark is left on when using OPV. Max bitrate is so constrained that OPV cannot really do much of anything. Like I said, you might as well be using cbr, at least you would get accurate filesize then. For some reason that I can't seem to understand, a few people still use it like this and so d2s has kept it in.

Thanks.
