Now, I'm not a professional matchmover. But I do a little bit on the side, so I'll throw in my 2 cents seeing as no-one else has

Alien spaceship shot seems fine. But it's impossible to tell if it's a technically good matchmove or not. But I say that if it does the job needed, then good.

The box shot seems off. The fact that you shot a real box underneath it showing that your 3D one is incorrectly placed and slipping (It's particularly noticable on the torn left hand top of the box.) I can't get a feel for whether or not it would feel alright if the real box wasn't there.

Notice how your ground plane is slipping rather severely agains the table? Use that ground plane to decide whether the track is solid. If it slips, it either means that the track is no good, or the ground plane is missplaced in 3D space.
So try to move that ground plane to the same space as the table, and then see if it still slips

The first test is kinda boring but seems like a good track, and the second test doesn't line up very well.

In my experience the trickiest matchmove shots are ones where you need contact between CG or real objects (like a real person on a greenscreen stage, or a CG element on top of a real ground). These are the times where a good track is important, and any amount of slipping ruins the shot. The most challenging involve plates with extreme lens distortion, camera zooms, or tracking objects that aren't totally solid (like faces).

Your UFO shot could have been done just as well without a matchmove because they don't interact with the stadium in any way and the camera move isn't crazy enough that you need that info, so it isn't the best MM example, your test objects looked more impressive.

Your box shot looks like a good track, but the objects on the table don't show it off. The box looks particularly bad because I can see the real box underneath it and the shadow goes off the table. I think it would be much better if you either removed the blue box entirely, or made it line up with the real one. Also your point cloud is a mess! clean it up or maybe only show your test objects and user features.

hi thank you very much .... are there any web sites which we can get HD footages for tracking


thanks

Hollywood camera work has some pretty challenging plates you can use:

Also Artbeats gives away a free HD clip every week and somtimes they can be useful for VFX. Usually worth checking out on a weekly basis sometimes they have some really useful stuff:

mahesh, i am a student. But what I am seeing here is proof on concept. Matchmoving with boujou/pftrack. This forum is reserved for reels, if anything keep up the work, just wrong forum.
