Using TMPGEnc, Compressing DiVX to MPEG makes it larger?? HE

[skapafeel]

When I have a normallly sized Divx .AVI file (600-800 megs), and I want to convert it to .mpg so I can burn as VCD, everything has lead me to believe that TMPGEnc is the way to go, so I used it, several times. Ive tried different files. I've tried converting to MPEG-1; MPEG-2; ive tried all the templates on file, I've used the guide from this site to manually set it up and no dice. It always makes the file bigger (about 900meg to 1.5 gig). What the hell is happeneing? I thought compression was just that, compression. Any advice on how to get the file down to a size that will fit on a single disc would be helpful.

what your missing here is the fact that divx avi's are already highly compressed, thats the whole point of divx. divx also has better compression than mpg1, so you prol wont get it any smaller without losing ALOT of quality than you already have.

i think the point you are missing is that divx/mpeg-4 also compresses. in fact, even more so than mpeg-1 or mpeg-2. take a look at this comparison chart for a 1 hour video in each format.

That is normal.
You already have a heavily compressed video (MPEG4) in DivX. During encoding it to MPEG-1, the video is being decompressed (decoded) and then compressed (encoded) with a less "effective" encoder. This is particulary true if you want to comply with VCD standards.

then the question pops up....how in the world to i fit a DiVX rip onto one CD?...people talk about it being done...

Try playing around with the SeVCD template to see if
you have a movie that can fit on one cd.

Why not just use two cd's? They're extremely cheap.

For 2 cd's try this :

Just encode to vcd getting an mpeg that's one big file.
Get a program like iFilm Edit and chop it in half.
Get Nero and burn each half on a cd.
Throw it in your dvd player and play it!

Just burn the DivX file to the CD as data.

Seriously... you've missed the point here. DivX is a high compression format (based on Mpeg version 4) you can quite happily copy the file to a cd without using TMPGEnc or anything else.

What a lot of us do here (with varying success!) is create a video cd which we can play on our DVD players. Currently (and not for the near future at least) there is no DVD players which will play DivX.. most players will only play VCDs (MPEG-1) and some will play SVCD (MPEG-2). If you wanted to convert your DivX into one of these formats THEN you start faffing around with TMPGEnc and compression.

Hope this helps a bit

faffing? is that anything like loveing (or loving)?

Divx is the best compression so far that can retain DVD like quality...Mpeg1 is the original Mpeg compression codec and can't produce real good quality at vcd bitrates.

You can get any movie on to one disc , with any format but that means you have to lower the bitrate so that it can fit but of course the quality goes down with it..So divx is the best for giving the highest possible quality for the size than any other mpeg compression method. Divx low motion at 600-700bps and 96kbs audio can probably fit 100 or more minutes on one CD ..depending on the movie..Movies with a lot of dark scenes will result in smaller files size so u can up the bitrate a little more for some better quality...but a lot of us are not very satisfied with the quality of a movie on one CD ..so we have no choice but to use higher bitrates and split the movie on 2 discs.
