In some scenes of a movie or dramas, we normally see a same person shows many copies playing around in the same scenes, and that is what we called steadicam.
Now we going to talk about how you do it with ASXMOV sliders.
It's not hard, because of the precisition of ASXMOV sliders path repeat function, keep the camera runnning the same path(orbit) that makes no differences.
>> How to shoot
Be ware of the lights, furnishings, standing positions and the position where you set your slider.
When we doing it, preset the Orbit of the camera will go, operate it once with no one in it, replay and see that video, and arrange where you want actors to be without overlap, will be convenient for the after effects.

Software used：Adboe Premiere 2015 CC
Step 1：Create Sequence
Create a new sequence in PR，input the materials in the order of time. becasue we were doing a moving cam, so we going to adjust the order of the material or along your scenario.
Step 2：Scenes matching
Match all the scenes basically，and divide them into two timeline: 1 and 2,
Adjust opasity of up materials to 50%.
then adjust the timeline scenes to match with each other, make sure every frame of both timeline video could match with each other.
and so on( if you have more videos)
Step 3：Painting mask
After the scenes all matching, we will cut the extra bit of each them.
This is it, we got 6 videos in here, block the 6.5.4.3 away.
Back to first frame, select suitable scale.
Select the second timeline.
Open PR effect control panel, select opasity mask pen tool, draw a mask for cover, click “Revesal”then adjust it util the two figures all could be see.
Because we were using moving cam to shoot, so the mask we making now shall be moving one either, and we need a key frame in here. Click "Mask path key frame", move the timeline, then adjust the mask（make sure the two figures still can be see). until this set of shot disappear. You will find mask follow function in PR, will follow automatically when the scene goes with smoothy motion. then previous, see if it work successfully.
Next we will go to the first frame of third video, we finished two sets of videos before，they are covered together, when we doing the third, mask we drawing need to cover the two persons in the videos before, need to be ware, "Revesal" and do as the steps before key frame and adjust mask range, util the person of video three shows, mask need to follow as needed.
Use this method to deal with the rest of them, and the video is complete.
