this video shows some ways of manipulating moving the splines around changing the color so if we then go into headaches blinds in the splines itself we can select these and make the lines thicker for both lips and we can change the color as well and perhaps make not -for this your blue okay within the keyframes and we here we've got keyframes selected let's pick the got keyframes selected let's pick the upper lip there are some options formanipulating this it's possible to move the the spline left or right sometimes,that'll be very convenient is in that case or something else we can do is to use this attract snakes it uses an algorithm to try and find the the closest edge and move all the knots towards the edge so if we click that it's done not too bad a job there sometimes they attract snakes works and sometimes it doesn't and so it's something to play around with you can click it more than once and it will adjust continue adjusting there's also the possibility to rotate and you can apply up to stick to applying it to the current frame really and so I think that gives you some tools at least it's not as sophisticated as for the ultrasound tongue tracking but it gives you some tools for applying the 2d splines to the image it's also possible to go through this and not necessarily apply every single frame so here or you can see there's a movement to that point there in time so we can add a new keyframe there I can move this down a bit instance, okay and then we can add an upper lip and let's ever let's see what attract snakes does well it's not too bad nothing I would extend that a little bit further there okay and if we move back with that at what point and there are two key frame there only and had a lower lip it's time I'll just to shift that topic in a bit wasn't really wanting to move here we go and if we moved between those two well there's we moved between those two well there's a little bit of a lag there she'd a little bit of a lag there she'd probably have it in keyframe there so we had a lower lip there okay so we've got the in-betweening handles the the other frames that you haven't actually applied the keyframe to  so that's just some ways in which you can speed up a fitting process under C enclose
