How do you determine........(help would be great)

..............How big an mpg is gonna turn out when converted from an avi file on tmpnec? I had a film which was about 600mb as an avi and when encoded turned out to be around 870mb which was fine cos ive got 900mb disks.

I then got hold of 'devils advocate', which was 560mb as an avi but when converted in the same way as above ended up being around 1.2gb as an mpg!!!

Why is this? I always thought as an mpg your going to be around 200-300mb more than the avi tops. Is there a way to find out this before encoding so I can know whether to split the file into 2 or not?

Any info would be great and save me alot of time - Thanks alot

Go buy the DVD and I'll tell you how to back it up so the filesize is what ever size you want it to be. But its well know that illegaly obtained avi's will increase in size no matter what, its encoded in the file

Funny that becaise it was a friend who had went and sold my dvd (some friend i know!) who gave me the avi that hed ripped from it so its all legal (For me anyway) and I understand your concern.

I understand that avi files increase in size when encoded but why some more than others? why did one 600mb avi encode to a 860mb mpg but then a 550mb avi encoded in the same way come to 1.2gb??? why is this?

try reading some of the guides, pay particular attention to anythign that talks about bitrate.

I would be more specific, but I don't feel like helping somebody who can't help themselves.

ok fine.. go to https://www.videohelp.com/convert and look in there.

This question pops up at least once a week.The problem is that these Divx/avi files use VBR MP3 audio and it causes the encoder(esp.TMPGEnc) to report a larger than normal file.Convert the audio to WAV first by importing avi to Audio Source in TMPGEnc and then go to File->Output to file->WAV.Then import avi to Video Source and WAV to Audio Source->encode.

BTW..I don't condone the d/l of copyrighted movies.

There's no correspondance between AVI file size and mpg file size. None. What matters are: length of movie (may it be AVI or anything else) and bitrate used when encoding (may it be to mpg or XviD or AVI or...). Use a bitrate calculator to calculate the size of the final file. Found under tools.

I don't believe it's legal to keep the backup of a DVD you sold or gave to a friend. Might be wrong, but I wouldn't go around telling people about your copying habits.

Nope, you're exactly right. Your right to a backup ends with the transfer of the original.

Of course, his bigger problem is that he has a friend who's a) selling his stuff and b) doing Divx VBR backups of the dvd's he's stealing just to mess with the guy he stole the stuff from! Some friend!
