Hasta La Motion!

So far the only solve I’ve had success with is a shot from one of Victors PFT classes.
I decided to go out and shoot my own one on Sunday, I took plenty of reference images and kept in mind having at least 1 single point for the software to use. Obviously having done Victors class last year, I know what I should be doing, so pretty much wanted to emulate what had been done.

I’ve done all of the typical stuff, undistorted the footage and reference frames, removed any rolling shutter artefacts etc

A 24mm lens was used, so I’ve put that down as ‘approximately known’ and have obviously set the camera to ‘rotation only’ in the motion type.

I’ll post up some screen shots shortly.
But in the mean time, has anyone come across typical problems which cause them to solve badly ?

how to matchmove a parallax error shot in boujou or pf track and how to place a patch in that track ?

can anybody tell me, whether a video file can be tracked? or just image formats only possible? boujou/pftrak/syntheyes/matchmover?

Hey all. I have a shot wich im trying to track but when taking it into maya, putting in some test objects its slipping, its very subtle but enought to tell that the cg isnt matching correctly.

How do u guys do the last 2% of the track to get it supergood?
I have tried various things, thou nothing relly seems to make any difference.

Is it a bad practice to change the keyframes in maya on the pftrack cam? like forbidden or a big nono?

seems like this must be very common? getting a track that is 98% correct but still fails cause of those 2% clearly shows that its sliding.

All hints and tips are very welcome!

Thanks!

Hi all, this is my first time posting and I’m new to using PFTrack with Cinema 4D. I’m having an issue I’m sure has been covered before somewhere regarding 3D objects NOT STICKING in C4D. Okay, here’s what I’m dealing with.
1. I do a simple tracking shot in PFtrack. Track sticks perfectly.
2. I import the Lightwave file into Cinema 4D. I see all the tracking points.
3. As a test I drop an object on to the points and it sticks like glue.
4. Then I add the background footage via bg-material etc. THEN
5. It not longer sticks. Everything is all out of whack.

Here’s what I tried as possible solutions.
1. I checked the frame rates in both Pftrack AND C4D. Made sure they matched.
2. I checked the pixel aspect in both programs. Yup, their the same.
3. I even slipped the camera key frames in C4D which seemed to help a bit but the track still shakes unacceptably.

Again, I check the frame rates in all areas where frame rate can be checked. Been trying to fix this for 3 days now and I’m at my wits end. I’ve seen numerous tutorials on PFTrack or SYNTHEYES to C4D. I’ve followed step by step to no avail. Does ANYONE have any clue what I’m missing? I know its something small. Again. Help. Thanks a ton in advance.
