2 questions: lo quality audio affect filesize prediction ??

[diji1]

Hi,

I recently encoded a dvd where the audio was quite a secondary consideration, so i encoded it using the lame preset "--alt-preset 80". After i muxed mp3 and avi, for the first time gknot got the final avi size wrong by a significant margin - 8 megs..... ok, its not much, but im used to 150K difference between actual and predicted filesize.

So my question is: does having low quality mp3 (abr 80, 32 kHz in my case) throw the bitrate calculator off in gknot ?? ... or is it just one of those movies that is hard to predict ??

Another small question as well: i read spmewhere that someone was using 7% for the compression check, but i can't seem to change it at the "save & encode" screen in gknot - how does one change this value ??

Thanks ! :)

32 kHz - i wonder if the audio is in sync. read the how-to please.

Yeah, lol, it's a little hard to tell as the movie is french but dubbed in English... it seems to be ok the whole way thru tho. I was a little worried about synch issues just from what i have read about using low kHz mp3 - but like i say, it seems ok.

Excuse my ignorance, but what "how-to" are you talking about ?? Is there something about using low quality mp3 in it ??

Thanks :)
