how remove tracking marker?

I put the tracking marker on the table, how do I clean it?

If you have it tracked, simply use the clone tool and paint over the marker from somewhere else. There's a bunch of tutorials online for this if you search "After Effects Object Removal". Might even be able to get away with the new Content-Aware Fill feature.

The most efficient workflow depends entirely on the shot. You can create a clean frame by exporting a frame as Photoshop layers and fixing the mark in Photoshop, then tracking the mark. Sometimes you can use Content-Aware Fill. Sometimes you can just put something else on top of the object. To point you to a solution that is going to be easy we need to see the shot, or at least see a frame of the shot and have a good description of the camera move and what you are trying to do with the shot.

i've tried using clean plate and link to 2d point with converted 3d point to 2d point with this scrift.

Reformat = thisComp.layer("LayerNameHere");
Reformat.toComp ([0,0,0]) ;

When you shoot for visual effects it is extremely important that you properly expose the shot so you have as much detail as possible in the image. If there is any significant edge detail on any plane you want to replace or any surface you want to track there is no need for tracking markers. None. They just add to the workflow. If you have a specific area that you need to replace and you are worried about tracking all you have to do is put something with detail on the surface. Say you wanted to put something on the foreground desktop. Just put a smaller piece of paper with a dozen or so black dots on it on the desk where you want the new object, then track and put the new object on top of the original shot.

Your shot is very underexposed. I was able to put Curves on the shot then Keylight and generate a comp that I could nest and then run Content-Aware Fill. Here's the pre-comp. Notice the extreme use of Curves to generate some really bright pink spots, then Keylight to poke holes, then the first pass of CAF in the main comp gave me fair results. It will take a little more masking and another pass to get it locked down.

The other option would be to use Mocha AE to Corner Pin Track both surfaces that have tracking dots individually. then replace the surfaces with a copy of one of the frames that has been fixed in Photoshop. 

I would probably go that route. If you can shoot this again, just remove the markers and properly expose the scene. The camera tracker should work just fine.

Thank you very much for your very helpful response.
this is just my practice, yeah this shoot is just the worst case scenario hi..hi ...
I do this only with the APS-C camera with ISO 800 and one lighting.
I think if I do it with the right exposure I won't find things difficult during practice. hi ... hi ..
