Hi this is my first posts here and im new to encoding. My problem is when I use the xvid codec set to Two-pass seasond pass and set it to target size I have a problem with setting the the bitrate calculator. Im not really sure how to set it up the kilobytes for the target size. What I do is i mulitply my prefered size by 1028...is that right?

for example i wanted a 230mb video tht is 20 minutes long then it ends up 640 mbs larger than i intended please help me any one?

:confused:

Multiply by 1024, coz 1Mo = 1024Ko

Did you made the 1st pass before the second pass ?

did i make a mistake lol?

Assuming you are using Windows - I just use the KB values as expressed in the Explorer file listing, ie. if my input filesize is 824,000KB I just divide that by 4 (in my head) which is usually ~ my target size or by 5 (with calculator) and decide somewhere where in between.

It's called "2nd pass" because in that mode it's a 2-pass codec, you really have to do the first pass first or it won't work.

You have to set the Audio too in the calculator or your size won't come out right, tho not as bad as what you're getting ;)

The 1st pass is necessary to analyze the video and generate a stat file. The 2nd pass will be based on that stat file (.stat) to achieve a given bitrate or file size.
This guide (http://www.doom9.org/index.html?/xvid.htm) will help you (Step 3).
