I think that Tom and GrimDude have jumped the gun slightly in answering your
question (no offence guys, it's just that there's a little more to be said
on the subject than "don't use Flash")...

Avoiding the subject of whether the video is necessary in the first place
(and excluding the idea of making entire websites using Flash, which luckily
pretty much no one does these days as they've finally realised it's like
making an entire website using full-browser JPEGs):

If you're talking about video displayed directly in a website, Flash is
actually a good alternative to what else is around (so the rest of my
response focuses on that use of Flash - video in a web page); if you're
talking about video that a user downloads, it's not a good format (MPEG or
something more universal is a better bet).

Now, on to Flash and video in a web page:

If you want to display animations on your website (right on the page), for
example if you have a gallery of animations that you want to be able to
stream, or you're trying to display methods/techniques of something, or if
you have video footage that you want to display, Flash is actually a pretty
good alternative to encoding the files in WMV, MOV, etc... if the animation
isn't of a very high resolution.

The reason is that most people have Flash Player 6 or higher, which means
they can display video encoded in the flash video format FLV.  This
eliminates problems with codec compatibility (for example, even if you have
the ability to play WMV files, some WMV files won't work because of various
versions of the codec, or because Windows Media Player just doesn't want to
play nice with the browser of choice that the user has), and of having to
get users to install yet another plugin or player that attempts to take over
the system (Real Player, Quicktime, etc - although these now have
non-official "codec packs" available, not many people want to go to the
trouble of installing them).  Flash is good in this respect because Windows
has for a long time come with the IE Flash Player installed by default.

For users of other browsers and platforms, the Flash Player is available
there as well, and is one of the few plugins that's pretty painless and
quick to install - this makes it significantly better than Quicktime, Real
Player or Windows Media Player 9/10/11/whateverthey'reuptonow in this
regard.

So, if you want to stream video and have it displayed on a web page (rather
than downloading it, or whatever), encoding the video in FLV in Flash is
actually a pretty good way.

Of course, there will be people who will not want to install Flash Player or
who don't have it installed, for whatever reason - but as has been
mentioned, this is the same with *any* plugin, so there will always be a
number of users who won't be able to view the content regardless of the type
of file you encode the animation in.

Now the downsides:

* Flash is expensive to purchase.
* Flash does a pretty good job of encoding MOV/WMV/etc into FLV but to get
*really* good quality and still have small file sizes, you either need the
additional Sorenson encoding program (I think it's called Spark), which is
an additional cost, or you need the top Flash version (MX Pro), which also
comes with a better encoder.
* Not all users will have Flash installed (but that's like any proprietary
format/plugin)

So in summary:

If you want to put video into a web page directly (have it display on the
page along with other content) and/or you want to stream video, Flash is a
pretty good alternative compared to Quicktime, Real Player and Windows
Media, so long as the video isn't of a very large resolution.  Flash does,
however, cost a lot, and to get the best video compression you'll need
either the most expensive version of Flash, or the standard version with the
Sorenson Spark encoder utility.  If you want to provide video in a format
that people can download, Flash isn't the right thing to use - something
like Quicktime, Real Player or Windows Media would be better suited, or a
more widely-supported format like MPEG would be even better.
