pulling my hair out

[james_stewart]

I just converted a divx movie using TMPGenc I followed everthing by tutorial. I previously extracted the audio with virtualDub (1.1gb wave file) I did an ES video only stream and used the bitrate calculator to figure out my bitrate i did everything exactly as the tutorial said now my .m2v file is over 4.3gb and my wave file is 1.1gb even if i convert it to AC3 it will be over 600mb. This can't possibly fit on one dvd, what did i do wrong? Doesn't the bitrate calculator take the wave wave file into account?

I'm pulling my hair out, this conversion just took over 10 hours. Maybe i'm missing something

The best thing to do so you don't have to go through another 10 hour conversion is to get the wav file to either a manageable .mp2 file or ac3 file. Once you have that done, go ahead and use whatever you would use to author your DVD , then use DVD Shrink to shrink it down.

I've had to do that a few times myself.

And judging by the m2v file size it didn't take into account your audio. That's too much (1/4) of your bitrate dedicated to audio if your file is very long time-wise.I usually use 192 for the audio so I subtract that from the bitrate. Since you were doing an ES it probably didn't. What I do is take the wav and open it in the audio source tab so it converts it to .mp2 then it automatically multiplexes the file for you. If you still want to use AC3 ,just de-mux the mpeg-2 file and re-mux after you use whatever you want to encode the AC3 audio. 192 or 224 or 384 bitrate of mp2 is the same file size as 192,224,384 ac3.

i used 128kb in the audio portion of the calculator, i followed the instructions completely now i'm stuck with this huge file. Does this happen often?

Well, the wav is uncompressed so the bitrate is a heck of a lot larger than 128 K. The only way you can use 128 is if you compress the file to a format that you can do at 128k like ac3 or mp2. An uncompressed wav ain't gonna get it for that file size.

Well you didn't use the bitrate calculator correctly.

1.) You didn't set the proper bitrate for the audio. LPCM WAV is 1536kbps but if you were going to end up using AC-3 then you have your choice of doing 192kbps for the "low" end of AC-3 quality or 256kbps for the "high" end of AC-3 quality. You entered 128kbps in the calculator. Hence the error in file size since you actually used 1536kbps

2.) You must have also made an error with your video bitrate since you say your M2V file is over 4.3GB ... not sure how you managed that unless you were thinking that a DVD is really 4.7GB which it is not. It is more like 4.37GB

Here is the bitrate calculator that I use:

BTW the bitrate you use in the calculator works for CBR encoding as well as VBR encoding. For VBR encoding you set a MINIMUM an AVERAGE and a MAX ... the bitrate given in the calculator should be your AVERAGE when using VBR

P.S.
It is a good idea to not try and MAX out your bitrate too much. You don't want to get "too" close to filling up the DVD as you need room for the authoring stage which adds some overhead (i.e., menu creation etc.)

This is great information you are giving me thank you. So now I'm stuck with a 4.3 gb .m2v file is there anything I can besides starting another 10 hour conversion? another question, when you use the bitrate calculator and us the recommended bitrate, what is usually the size of the resulting .m2v?

Author to an oversize titleset on your HD and then use dvdshrink.

You didn't read the first paragraph of my reply to you:
