Changing audio rates

[Puggsley456]

I extracted an audio file using virtual dubb and the files bitrate is 192 kb/s.
Whae I load the propper template in tmpg, the audio changes from 192 to 224kb/s. Will this affect the quality of the audio of the incoded file?
Why doesnt it leave the audio at 192 kb/s?

the template you are selecting is setting the audio bitrate to 224
no point in encoding a 192kbit file to 224kbit.. hit the settings button, and go to the audio tab, and manually change the value to 192

Whan I go to change the setting the box is greyed out and I have to load the unlock template to change it. Is that what you mean? And will that affect the playing of the movie on my dvd player? is it an XVCD then?

My movie is 81 min long and I want to try to fit it on one 80min 700mb cdr is it possible?
When I try using the wizard to see the final size of the file it ends up being 807.15 mb. That is with the 224 kb/s audio. Will the file size change when I change the audio rate?

Ive even tried trimming the credits and the intro to shorten the file length but I cant squeeze it down any farther.

I guess technically this would make it an XVCD. However, i highly doubt any player would have issues with playing a VCD where the only modification from standard was lowering the audio bitrate. As for the file size, yes, it will be less. I dont know if it will be 7.15MB less, as you need, but its worth a shot.

Using the java bitrate calc on this site, it shows that a 81Min 00Sec movie will fit on 1 80 min CDR with audio bitrate @ 192kbits, with Video bitrate of 1144. If you VCD is 1150(standard) and/or is over 81Min at all, even by a couple seconds, you may have to drop the audio bitrate down to 160kbits.
As long as you use a program like BeSweet to encode your audio, you shouldn't notice much of a loss of audio quality

According to the bitrate calculator on this site, you can fit
84Min 40Sec @ 1150Kbits with audio bitrate @128kbits on one 80Min CDR with 5Mb headroom for other misc VCD files.

What if i just select the 160 kb.s option when I unlock the template? Do I have to reincode the audio seperately or will tmpg do it for me?

TMPGenc will do the audio encoding for you, but for best quality, i would suggest downloading toolame off the tools section, and going into the program preferences of TMPGenc and setting toolame.exe as your external audio encoder.

Where Can I find help on converting the audio from 192 to 160 using BeSweet? Their website doesnt explain how to do it?

Hey Johneboy, I tried adding TooLame to TMPEGEnc's (2.59) environmental settings and it wouldn't do it for me. It would stop me whenever I tried using TMPGEnc and would say for me to change the settings so that I wasn't using it anymore. What gives?
