This should get you started.
Put the original footage on the bottom layer, duplicate the footage layer and move to the last frame where the dancer's foot goes out of frame. At that point either use the Composition/Save Frame As/Photoshop Layers menu or use Layer/Time/Freeze Frame (if the foot only moves out of the frame once). Now you are set to start the masking process. If you have multiple times when the foot moves out of the frame you need a new PSD of the last good frame each time. If the foot only goes out of frame once you can use a freeze-frame.
The next step is to create a mask for the foot. It is easy in Photoshop, and fairly easy in After Effects. You will want to add some feathering around the heel. If you set the anchor point of the layer on the center of the heel it is going to be easier to match things up.
Trim the layer so that it is only long enough to cover the part where the foot is out of the frame. Mask the foot as shown and add some feathering below the heel. Animate the position and rotation to match up the movement as close as possible. You will probably need to add Puppet Pin to deform the foot slightly as it moves up and then back down. If needed fade out the last two frames when the toes come back into the frame. You want the replacement foot as small as necessary yet big enough to give you something to match up with the rest of the foot. In this screenshot, taken from your sample images it took 6 puppet pins to match up the foot so there was no visible shift in the size or look of the foot.
I hope this gets you started.
also i am realizing that there is another problem
the original clip has the foot out, there is no space to add more
what you see in that screenshot is the orginal footage reduced to 30% with another clip underneath
so how shall i proceed?
ok i am going through
but at certain point the rotation of the leg make te foot too different form the freezed one...i am not sure if it can work
by the way i am searching for the puppet piun...where do i find?
i try to use the puppet pin (position ) tool...but for me seems difficult to put it in that way (the foot)
First, you do the work in a comp that is larger than your footage so you have room to add the foot. I would start by picking the in and out points for the shot in the Footage Panel, then create a "Footage comp" from the trimmed footage, apply any garbage mattes(masks), and Keylight to remove the background, then pre-compose the keyed footage (keyed comp). The next step would be to open up the Footage Comp and increase the height to allow for the foot to be repaired. You have the option in the composition settings to expand only the top of the comp like this:
That will give you more room at the top.
If the angle of the foot changes dramatically then you may need more than one replacement foot image. If you can share the footage I will try and share the workflow. If you can't share the footage, share the last good frame and the first good frame where the foot comes back into the frame.
The next step is to create the PSD files you are going to use to extend the foot and mask them so you can easily blend them with the original footage.
Put one PSD on top of the other on top of the pre-composed Keyed comp, trim the in and out points of each masked PSD to the last good frame and first good frame, then set the blend mode to something that you can see through so you can check how the feet line up.
Puppet pin is just one of the tools. It looks like a pushpin. You'll have to go through the tutorials to figure out how to use it. It is an easy way to warp layers as well as do animations. You always apply Puppet Pin to a layer that already has transparency, view the mesh, then animate the position of the pins. A layer that has Puppet Pins cannot have any animation (keyframes) for position, scale, or rotation. You will match the foot movement later.
Here's the tricky part. Move to a point between the in and out point of the layers set up a 2 to 4 frame overlap. Add 4 to 6 pins to each layer. The first good frame should be at the out point, the last good frame should be at the in point. Go to the overlap and while using the blend mode to see through the layers, move the pins on both layers until you get a good match. If the match is not perfect, set up a 2 or 4 frame dissolve between frames by animating opacity. When the last good frame image seamlessly turns into the first good frame image change the blend mode back to normal and pre-compose the morphing foot. Now all you have to do is animate the position of the pre-comp so that it matches the position of the foot. It may take a couple of tries to get it right, but you should be able to pull it off.
I recently worked on a shot (a comp) that was only 154 frames long. It required 44 masked PSD images morphed with Puppet Pin containing least 8 pins pre-composed and overlapped together un a pre-comp with at least 3 sets of keyframes each to complete the project. Even though your shot and my shot are completely different, the workflow is exactly the same. Find something you can use for each end of the shot and then morph between them.
It's going to take some time. The workflow is pretty much as I described. Here's a project file that gives you the basic steps. All that is left is to finish the puppet pin morph in the nested comp, animate the mask in the main comp, then finalize with some color correction. It would probably take me two or three hours to finish the project. When you do the work you need to be working with the original files. You want as much detail as you can possibly get.
Step 1: Trim the footage, create a new comp, resize the comp, duplicate the footage, set markers for the last good frame and the first good frame, freeze-frame the layers, mask the foot.
Step 2: in the Morphed comp start with the last good frame and animate the puppet pin moving the repaired foot as close as you can to the guide layer original footage. When the first frame layer has gone about as far as you can go because of the shape of the foot and the lighting changes turn off the layer and start on the first good frame layer beginning at the out point. When the layers meet, overlap, and do a crossfade. You won't get perfect edges and blends yet, but get as close as you can to a realistic-looking foot.
Step 3: back in the main comp animate a soft edge mask to hide as many imperfections as you can, then apply color correction.
Like I said, this is going to take a while but you should be able to get something that is usable.
