mpv came out undersized, using credits bitrate tweak...

[Matthew]

Versions: EclCCE 1.5c, CCE 2.67.00.11

I set up an encode of a ~2 hour minute movie with a bitrate of 4480, and used the credits bitrate tweak of EclCCE to limit the last ~5 mins to 1500. I saved the project and ran it at the command-line.

Anyway, after compiling the project I realised the vobs were undersized by a bit (40 MB or so). On further inspection, bitrate viewer reported an average bitrate of only 4365. I just went ahead and burned the project anyway.

It's as if CCE did not reallocate the bitrate after setting the credits to a max of 1500.

Has a similar thing happening to anyone else?

BTW I still have the vaf etc and if I change a range's min/max bitrate manually then the other areas do go up/down in the curve.

I'm not aware of a problem with EclCCE in this area, bitrate tweaking always worked fine for me.

What did you use to calculate the bitrate? My bitrate calculator (Fit2Disc (http://shh.dvdboard.de/fit2disc.html)) calculates 4731 kbps avg. for a 120 min PAL movie with one 384 kbps AC3 track.

Thanks for the reply.

I used DoItFast4U's bitrate calc (that's all I use the program for though :)).

Just realised I've jumped the gun, yet again. (Although I didn't mean to imply it was necessarily EclCCE at fault).

Coincidentally I still have a half-hour tv episode I recently encoded at 3880, without any bitrate tweak. And guess what bitrate viewer reports as the bitrate?

3765

So seems like either the DoItFastForU bitrate calc isn't as accurate as I'd like - coupled with inaccuracies (?) in bitrate viewer - or CCE is undersizing.

I put the output size of the mpv into Gordian Knot, along with the length and it says the average bitrate is 3872.

So it looks like it's a calc/bitrate viewer issue. I may compensate by manually pasting in a larger size in the DoItFastForU bitrate calc.

is fit2disc worth the donation? I don't see many threads about it and was thinking about getting it.

Definitely, get it. Most accurate BR calculator there is, IMHO. Highly recommended.

wow, I totally missed this one, I just saw a new version pop up, so I will be getting that one, thanks RB :)
