GREAT tut! I've watched a boatload of PFtrack tuts and the helped a bit but left me with just more questions. This was clear and concise... can't wait for the next one! Thx!
Thank you very much. This tutorial is pretty good, it shows some errors or bad tracks that you encountered. Unlike other tutorials that everything always works. I'm working on a scene where the character's arm is moving and also the camera is moving. I want to put an object on the arm. So just wondering how can I combine the 3d camera tracking with object tracking?
Great Tutorial, it helped me a lot but i have a little problem. I put a test object node at the end of the hierarchy and i added mushrooms. The problem is they don't have the correct size in my viewport. Furthermore, the grid is correctly placed. When i put a mushroom on a point tracker in the background, it is bigger than a mushroom on a point tracker in the foreground. It is strange. Do you know why this happen ?
Great tut! Am used to georeferencing geological sections in 3d for digitizing and model creation. This tracking process seems analogous to adding control points. But it doesn't feel like 3d, ie you can't walk behind one of the mushrooms in the clip solved in this tut. Or can you? I am I correct if I understand you basically have to film and resolve the views from the whole final Trajectory? Ie am I wrong if I say a true 3d representation cannot be made unless the entire scene or object is encircled? Is that what a 3d scanner does? Looking forward to the other software tuts you mention. ( in my field we have remote sensing / image processing / surface modelling software ie Erdas imagine and Virtual Gis. The software vendors call that and other similar visualization software 2.5 D . Then one has gocad where you can build wireframes - ie do detailed topological modelling changes - I am guessing that maya would be the animation / film equivalent? Thx ums
Can you tell me if an inexpensive Sony Handycam HDR-CX240 would be good enough for matchmoving? ?? What is a decent camera or video camera for the job? I have no data on the lense or camera, no idea of it is interlaced or what type of adjustments need to be made made to the footage prior. Other than sometimes seeing some straight walls that can undistort with? then the footage in max is undistorted?? what do do in such case also? Every attempt I have made at this fails miserably. A friend with allot of animation experience told me not even to bother but would like to learn. Can it be that hard? I see allot of decent matchmoving examples on youtube that give me hope. Thank you for your tutorial one of the best out there for sure.
+TunnelvizionTV How to reopen the project in PFtrack. I tried to reopen my previous work I click SWITCH it says corrupt and i also try Re-link it does not work.
No criticism of the creator here but I'm at 9:08 and if I was using 3DE I'd be onto the next shot by now. With a toilet break in between because of all the coffee I'm going to consume watching the next twenty minutes of this video. Tutorials do not need to be thirty minutes long. And I'm not convinced PFTrack is 'the most innovative product of its kind'. Oh well, I guess we'll find out!!! Update: We're at fourteen minutes now and we've learnt two things, and we've watched the user do the same thing fifty-six times now. It's just like learning how to track on 3DE back at Weta, in 2003. In fact, it's just like tracking - do the same thing over and over and over again, hit 'Solve', and you're done. Easy! What is a gold key? What happens to the keys before and after when you hit R+? Or H+? Why do you need to hit two buttons to do the same thing? Why do you need to track forwards and backwards? Why is my hair falling out? Okay let's see what happens in the next twenty minutes... 23:40 Okay this procedure is what we had to do back in 2004 with Boujou. Spending ages eye-balling how good auto-tracks are. In 3DE there's a graph that does this - you can literally pinpoint which points are tracking poorly. Select and delete ( single key-stroke btw. There's some innovation - doubling the amount of effort it takes to delete something. )
Thanks for the tutorial...I'm just learning Pftrack and I'm having a scaling issue going to 3ds Max. I selected two trackers in orient scene node and input the distance...in meters right? I left the scale in export node at 1. When I bring it into max and add objects everything is tiny, not to scale. Would you adjust the scale in the export node until it seems right?
Thanks for the tutorial I have a question, is there a smoothing between two keyframes on user tracks? Let's say my tracker drives away at frame 10, but it's good at 0, can I fix it at 10, and somehow interpolate between 0 tracking and 10, so there will not be a one frame jump on the fixed frame?
Nice tutorial : ) I would love to see one where the camera pans. I want to motion track, typing a keyboard pans to the right looking at the desk. The back to the keyboard. This suck, just jump around. I even placed markers.
Does pf track only accept image sequence footage? if so whats the best way to export an image sequence/best format? (PS: for those who are having trouble loading image sequences in maya, dont use underscores when exporting, maya has trouble recognizing)
Really like your tutorials. How hard would it be to track 3D 360 footage for VR? Seems like the next big thing would be fun to make things look real in a VR setup. Some cheap 360 cameras are coming out, even some 3D sterio ones. Would it be a nightmare to track?
Sweet as always thanks for your reply. Do you consult? I might need need to get some instruction up the road. This stuff is hard to learn, well worth some investment. If so can you message me contact info and rates so forth. Thanks!
Also I tried the VR headset recently the one that goes with the phone. It was really amazing, 10x better than what I expected. Can really see how this will be quantum leap for CGI work. Imagine making your renders and footage look real, I mean there. Even crappy renders can look cool. An throwing the models into real footage wow. Especially footage that is actual to where the person is standing the whole thing is mind blowing.
Great Tutorial a few questions; You must use AutoTrack even though you used User Track, this is a must ? I'm having problem tracking a truck, can you offer some help ?
Hi, you don't have to use auto track, I find that it can give you better results but if you have an excellent user track with enough trackers then no need for auto track.
+TunnelvizionTV I'm having difficulty tracking a truck, due to power lines in the background, I was informed to use planar tracking ? If I could show you, hopefully you can help ?
Does anyone know how to track a shot that begins with the camera looking up (no floor), because the PF track thinks that the roof is the floor and it just stops tracking once the camera tilts down
@@Ruan3D Thank you for the answer. :) Yes, I do. I am using png sequence. I saw that you can import the .mov extension directly to pftrack and I was curious. Thank you so much. :)
Thank you for your instant reply and assist, but I noticed in that tutorial the camera is static. My other concern with object track with moving camera, is my camera is a nodal pan on tripod, being the tracks are in an arc in nodal pan does this make 3d object track impossibe? Do you consult? Looking for a few hours of direction . Thank you
+TunnelvizionTV . Very interesting , what would your node tree look like in such case? Image--> ;Autotrack --> Camera Solve --> User Track -->Object solve --> Export?
+TunnelvizionTV thanks that helps allot, in that tutorial the camera scene was not tracked, only the object, can you tell me how you put both together? I did not see any trackers on the surrounding scene. I need to matchmove some background stuff too. Also Nodal pan I am worried about since it does not create accurate 3d pointcloud type of tracks thanks again
if you had a moving object in that scene , how would you track for that object? would you mask it out, solve camera for scene, then add object track node after the camera with same mask inverted? then another export?
I'm starting to hate pftrack. When I solve the trackers, everything is fine. I solve my camera and it solve it very well ( 1,5 average errors). BUT when orienting the scene. the floor doesn't stick and for the whole footage but jump out of place half way through! When exporting to Maya is impossible to matchfit. What is wrong I got no clue. It only happens with this particular footage.
I did. I tried hadding more trackers and resolving and it seems better, but still not perfect. I think that it might be because the footage was taken with a mobile ( Lumia 830 ). It is supposed to be very good, camera wise but, when rotating, the footage seems distorted on top. In a 690 frames footage, 1 to 450 are fine then 451 to 580 is not aligning in Maya, then from 581 is aligned again!
TunnelvizionTV Thanks for the suggestion, unfortunately the distortion was very small ( 0,0012). But I noticed that, even though pftrack solve everything, In the 3d space it's not right at all. A flat wall, with multiple tracks is showing the tracks not in the same axe in the suface of the wall. it's like the wall has variable depth in 3d space. This is so annoying. I tried with stock footage found in the web, and everything is working. It must be the Lumia 830. Also, Microsoft says in specs 26mm focal, but estimate tracking says 12mm ?!?
73maxmau I suggest you contact Pixel Farm. I am not using PfTrack but PfClean. I have found PFClean 2012- 2013 a complex app and counter intuitive to use. And now the 2014 release features a new interface! Anyway, Pixel Farm should be there to help you.
I dont see why you are attacking me. Also I didnt say I find his "mouse clikcing noises" annoying but those clicking noises he made using his mouth. He didnt feel offended and I didnt want to offend him. Theres no need protecting him. Why acting like a kid?
