I'd like to know how I can minimize video movies (which kind of
programs) to send them through e-mails; e.g. I have same 12,5 MG
movies and I'd like to turn them to 200K.

Hi Emildo-ga.

The kind of program you would be looking for is called a 'converter',
to either convert from one format to another or to convert to a
smaller size - sometimes both.

There are several varieties of converters, ranging from the free
simple converters to some that cost several thousand pounds and are
used in professional design.

For this particular solution, a free or shareware converter is the
optimum solution: You don't need exceptional quality, and it's not
something that is financially viable to purchase for just one use.

This site has loads of converters of many different kinds, some free,
some shareware, some demo versions.  Looking through the list, I saw a
couple which could be useful to you:

fmp141.zip - The Fast Movie Processor
winsmvid.zip - SmartVid file converter
(Please note, none of these have been tested by myself, so I don't
know if they work or not)

If you specifically want small movies, it might be worth checking out
the DivX codec.  One disadvantage of this is that your recipients will
need to download the codec (The piece of software that tells your
computer how to use the software) before they use it.

Again, I have not tested any of this product, but you might be
interested in looking at AviEdit -
http://www.am-softhome.com/aviedit.html - which appears to do much of
what you require.  The product is free for 30 days, and after that is
$25 to register.

I think these programs help you to send your e-mail videos.  Please
bear in mind that size is often linked to quality, and that
compressing the videos down from 12+ megabytes to just 200KB will
cause a major decrease in the quality.  If your recipient is amenable,
AviEdit will let you split the video up into multiple files which you
can send across a period of time so you don't overload the e-mail
servers, and don't have to upload/download too much at any one time.

Hope this helps!

I'm very satisfied about the answer. I've just read it; I din't check
out the sites yet. Maybe it deserves a 5 stars... But I don't know
yet; I mean, I must check out the sites first.

This process is also often called "compression," because you are
compressing the amount of information in the original signal. (video =
3-D signal, audio = 1-D signal) There are two types of compression,
lossless and lossy. Lossless compression will create a compressed
signal, from which you can recover the original signal from the
compressed version. Lossy compression removes information from the
signal during compression, and when the signal is recovered it will
differ from the original signal. Ideally, the recovered signal is not
noticably different from the original signal. MPEG1,2,4 are common
video compression standards, and MP3 is a common compression standard.
