Ani.net and Define Size Max 2040MB

[psxiso]

Hi,

I use Avi.net to convert DVD to XVID, today I just have a problem where a custom size output is not accurate. I set the output to 1950MB for a 110minutes movie and it came out 680MB. I check out the official website and it mention i must use XVID 1.1.2 so i download the latest version of XVID and now i got a question.

The reason why I set the output size to 1950MB is to make sure its under 2GIG so i can burn to DVD and watch it on DIVX player. (any video over 2gig will not play). I read on the official website of Avi.net, it said Custom size is for small video clip, for movie, use the defined one.
So IF I choose ".max 2040MB" in Avi.net, will it output under 2GIG? Because I want to have good quality, if I choose "1493MB" I miss out about 400MB.
Or should I manually enter 1950MB to be safe and ignore the info on Avi.Net website?

many thanks...

Or you could work out the correct bitrate to get your file size, and tell avi.Net to use that instead.

110 minutes, filesize 1950 MB, 128 kbps Audio (assumption) gives a video bitrate of 2267 kbps

thanks, i'll give that a try, I hope i can get it under 2 GIG using ur method. I'll put it in 2250 kbps to be safe.
I'll post the result later.

I put in 2250 kbps for 1.50 hrs movies (128kbps mp3, 640 x 352)
The result is about 100mb lower than from the calculator, it should be 1.9gig but it came out as 1.8gig. That's alright, close enough.
Also the second pass take too long to encode, about 4 hours for 2nd pass and two hours for 1rst pass, total 6hrs for 1.50 hrs movie. While a one pass encode take about 2 to 2.5 hours to complete.
i think i should avoid 2nd pass encode in the future unless its the only option.

The way a multi-pass VBR encode works, the first pass is an analysis pass to determine the best way to allocate the bitrate to meet the target. The second pass refines this analysis and does the actual encoding.

If you change to a single pass VBR you may get much lower quality and may not come close to your target.
