Not sure what you mean Saph. Do you mean how do you make a Mediatracker intro? Or do you mean how do you video (record) your mediatracker intro? or are you making a intro in third party video program altogether?
I think he ment how he can record the whole track including intro.
I don't think there is an ingame/MT function for this.
You probably have to use fraps or whatever recording software and start recording when you open the track and play it.
I tried it and it the came was f**ked up for some reason, like the coordinates where completely wrong. Otherwise the intro worked fine but was of course useless.
E: Can anyone translate what I just said there? lol xD
