Bitrates: Cq matic final cq always 89.xx
 

hi,
when using cq matic my final cq is always 89,xx!
ive deactivated things like detect scene change and don't know whats wrong ):

also the path to the file (the path in the tmpgenc project file to the mpeg2 file) has no spacers or something like that.
"source" is an mpeg2 file!

hope anyone can help me.
please dont answer use search, thx.
there are many topics with more than 30 pages...

sorry for wrong expressions, my english isn't the best, but i think you can understand it!? ;)

Post CQMatic's log :!:

-kwag

k, here it is:
CQMatic Log
thx in advance!

All size are negatives, that means TMPGEnc doesn't encode anything.

Be sure to have cut editing reset and range selection unckeck in the advanced settings of tmpgenc before to save the project (as text file)

ive done all like written down here:
http://www.kvcd.net/forum/viewtopic.php?t=5145

-saved as "text" project
-source range disabled
-detect scene change disabled
-start frame is 0 and end frame -1 (at source range)


any more i should change?

hmm damn i havent changed really anything and now it seems to work...
i reseted source editing... but thought it was reseted, cause start frame was 0 and end frame -1....

ive chosen prediction only now it started tmpgenc and it is encoding...
already 1:14 (source pos.) encoded.... thought it will only use a small sample, max. a minute or so?

This part is also important (in bold):

"You must make sure that you save the project without source range selection, and "Cut editing" cleared (or reset)"

Did you check that point ?

its saved without source range sel.
you cut editing button at source range, right?
reset is grey (cause its already reseted!?).

or do you mean something else?
by the way: it encoded over 5minutes (source pos.)

grey = already reseted, yes. And it seems it was your problem as after doing it, tmpgenc starts to encode (yes, it does only a sample of 120 sec for prediction else it will take DAYS to find the optimal CQ :-))

hmm i've got a new problem, a strange problem...
i've unchecked source range, then i save my project.
even if i close tmpgenc, start tmpgenc again and load the project its still unchecked - like it should be.

but when im using cqmatic and it starts to enode (precision mode) source range is again checked.

ive reinstalled tmpgenc & cqmatic - still the same :cry:
im using TMPGEnc-2.520.54.163-Plus-EN - can this be the problem?
has ever anybody tested cqmatic with this new version?

For sure ! CQMatic does use source range selection. And that is why it must be unchecked in the initial project : without this, CQMatic can't set its own selection range settings and that makes TMPGEnc to fail.

hmm *lol* k, thx, didn't know that ;)
but how already posted:
it (still) starts encoding, encodes, encodes - it dosn't stop after 120seconds, i already was at over 5minutes source position (the i chanceld). anyone knows whats wrong when its not the source range option?

(of course i've chosen prediction only, also shown in the log)

This problem was already reported to me twice and Kwag never gave a solution. :-(

Perhaps this time ?

Redo your .d2v project file :!:

-kwag

ive used no dvd2avi and no project file the whole time, but now ive saved the mpeg2 file as project with dvd2avi and chosen it in tmpgenc.

but also with the .d2v its the same problem:
ive chosen prediction mode, it starts encoding and dosnt stop (after over 3 minutes source position ive chanceld).

here's the log, may be it can help to find my problem:

There is no problem 8O
It's predicting :!:

-kwag

well it encodes and encodes, once it was even at 10minutes... (source position!)
thought there will be only encoded a sample of 2 minutes for every tried cq or is that wrong?

If you load your .tpr in TMPEG, and then go to source range and scroll all the way to the right, does it read 97 minutes :?:

-kwag

it reads/shows 96,27!
even once tried it with 96min (entered @ cqmatic) - same problem.
maybe problem is really the new tmpgenc version?

could even post a screenshot of my tmpgenc config(s) if needed...

What version are you using :?:
I'm on 2.520, and never had a single problem :!:

-kwag

im using TMPGEnc-2.520.54.163-Plus-EN
i wish i also wouldn't have any problems ;)

i now even tried TMPGEnc Plus-2.510.49.157 - same problem so i think the version isn't the problem. any ideas what could be the problem (my problem is that it encodes and encodes at prediction mode, normally it should always only encode a sample of 2minutes at prediction mode!?)

kwag what version of windows are you using?

XP Prof. But we've tested on XP home and Win98SE. Works fine on all.

-kwag

SEEMS TO BE A BUG!? I'VE FOUND THE SOLUTION FOR MY PROBLEM! :)

i was using mpeg2 files, *.mpg - then i tried it with a demultiplexed file (*.m2v @ tmpgenc) - works fine, it encodes 3000 frames (exactly 2 minutes!!!).
(is this really a bug?)

but my next problem: i use calcumatic for getting avg. bitrate, but if i chose a [u]higher[/b] audio bitrate and click calculate again the avg. gets lower, shouldn't it get higher???

now im looking for an alternative tool where i can chose the m2v file (video only) and the mp2 file (audio only) and get the avg. bitrate from these 2 files, somebody knows a tool for that? or how can i manually get the avg. bitrate when having an mp2 & m2v file?

No. The higher the audio bitrate, the less space you leave for video, so average will be lower.I think you've got it wrong :D
Average bitrate is for video streams. Audio streams (.mp2) MUST be encoded at a constant bitrate. Not variable :!:
You just need the play time of your .m2v, to calculate your average for your new target.
Just open your .m2v with CalcuMatic, and it will tell you the play time.

-kwag

well i did, but i thought avb. bitrate is for video & audio, thx 4 info!

but whats with the *.mpg problem? it really seems to be a bug!

Demux your .mpg with TMPEG tools, and remux both streams with BBMpeg. See if the error dissapears.

-kwag

i've done so, demultiplexed with tmpgenc and multiplexed with bbmpeg - same problem.

seems like cqmatic has its problems with *.mpg files.
i think you should also try it once with an *.mpg (mpeg2) file! :!: :?:

by the way: the "source" mpeg2 file is 789MB, the "new" (demultiplexed and then multiplexed) file is 794MB, somebody know how to get it again to 789MB (in this case not needed but i'd like to know for other things)?

and: why isnt it possible to enter seconds at movie length (at cqmatic!)
wouldnt this be more precise/exact? (difference is small cause it cant be higher than 59s if doing right and so its sure not more than 6MB or sth. like that but why not? so you would come nearer to 800mb or am i wrong?)

CQMatic doesn't read MPEG files :!:
TMPEG processes the files.
CQMatic doesn't know anything about any media files, so the problem is either with the source or with TMPEG.
Just round to the nearest integer. Ex: 10:15 = 10 or 10:35 = 11.
The real calculation is already done when you get your correct average bitrate (CalcuMatic, etc.), where you get exact minutes and seconds.

-kwag

well, tmpgenc reads the mpeg files, but it seems like cqmatic cant get a source range over tmpgenc when using *.mpg or sth like that
=>cqmatic gets problems with mpeg files even if it isnt reading the mpeg files!? and so it isnt really compatible of mpeg files? (maybe not an error of cqmatic, but fact seems to be it isnt working with mpeg files!)
i tried various *.mpg (mpeg2) files and had the same problem with all of them...

if you also would try it, we would see if its only my problem or maybe the problem fo all? if its the problem of all, i think a note at the download would be useful!?

What about if you frameserve your mpeg file from Vdub :idea:

-kwag

sorry, i'm not using vdub or vdub mod!
i also have no idea how to work with vdub (mod)!
i can just say you i've the problem when i chose the *.mpg files at tmpgenc and even if i save my *.mpg file with dvd2avi as *.d2v project and than chose this one at mtpgenc!
