FRAPS

No need for those replay files you can simply record them as RAW AVI's.

Then use
VirtualDub

To compress it!

Fraps doesnt record with W:A or WWP, Worms hooks all of the keys, so Fraps can't get through... sorry.

are you sure? I'm sure I've heard of people getting fraps to work with worms...

Lemme give it a try

EDIT: Nope doesn't work, maybe a key hack of some kind?

Doing that would probally mean editing on of the Worms DDLs/exes, unless someone managed to get Fraps to use a joystick or mouse key or something.

Couldn't you have tested it before posting about it?

I second that

what is fraps? and how does it work?

then you would lose out on tons of fantastic features like, speeding things up, you can't choose when you look at the chat, it wont tell you if someone has used a loop hole or somthing.
no slow-mo and i'm lazy.

W:A saves played games with the level of compression you can never get with movie files(Fraps records everything to those formats). No matter how well you compress games recorded with Fraps, it's highly doubtable that you'll be able to get, say, a 5 minute game below 100-200 kb, while W:A does that automatically.

Also, it's easier to edit movies than W:A recording, some people could use this to their advantage(showing recordings of amazing games/shots that have never actually been played)

...

The W:A Recordings aren't actually frame-by-frame...

It's a bit like a vector, it's mathematically calculated.

it records ever button that you press and the exact time you press it and puts it into a text file.
The game can understand it and sees it as a game that has been played.
at least thats what i think

You got the right idea

except it actully uses random bytes as things, instead of text
