Hi Dr. Sassi,
Thank you for your answer. I'm trying to learn from the best like of course Maxon Training Team, Motion Design School, Coloso etc. but yea sometimes certain things do not work as in the videos and then all sorts of problems begin.
So regarding that lack of access to the constrains - looks like most of the time it does work and I am able to adjust it, just sometimes it doesn't, I'm gonna keep looking at it and try to figure out what's wrong when it doesn't work.
And regarding the tracking itself (and the purpose why I did want to adjust the constraints) - so here are the problems I encounter:
- Regarding the position constraint: so let's say I pick a certain feature and the grid looks pretty much ok, but then I decide to change a feature to a neighbouring one (and all those features that I’m choosing from are eg. on the street, not one on the street and another one in a completely different place like on a wall or something) and suddenly the grid goes crazy. All the features that I’m choosing from are green and they seem to be placed nicely on the street. What may be the reason for that? (video number 1).
- Planar constraints: same here, I choose 3 or 4 features on the street and sometimes it works nicely and sometimes the grid is completely skewed despite choosing features on the same plane like street. Also sometimes selecting (or rather snapping to) features works fine, sometimes it doesn’t snap (video number 2).
- Vector constraints: even though I select features that lay eg. on the fence , the perspective can be totally off.
- Does it matter whether I create position/planar/vector constraints first?
- Regarding the lens grid - so far I've used videos from the Internet but I don't remember anyone using it in those tutorials/courses (from Maxon Training Team, Coloso etc.) that I've seen so I guess that's not necessary?
- Is it worth to create 2D tracks in a few different sections of a video? Like in the most important part, at the beginning etc.? And do they somehow blend together?
- Could I actually skip auto tracks and create all tracks manually?
- I think Noseman said in one of Maxon Training Team Youtube videos that 7 good tracks is all I need to succesfully track a footage so could I just create 7 manual tracks in nice constrasty spots and have a nice track?
- On the other hand in a course that I'm doing now a guy (that has worked for top studios in the world, not just a random youtuber) added like 10000 auto-tracks so that's quite a difference, 7 vs 10000. But actually he generated a mesh after that so I assume that I do need that much tracks to generate dense, accurate mesh? But other than that, if I don't want to generate a mesh does it make sense to create so many tracks?
- If I have a veeery very long footage that I want to track with lots of diffucult areas like reflections, trees etc., do I just have to manually remove all bad tracks no matter how much time it takes? Cause all those bad tracks, (if I keep them, and no matter how many good, green tracks I have) make the final tracking result worse/bad/impossible to use, is that correct?
I've also created some screenshots, here's a link to WeTransfer: https://we.tl/t-klxiuNV3Bs
7. There's a folder called NarrowStreet that I wanted to use to follow a nice course that I'm currently doing and each time I tried to track it in Cinema, I ended up having a grid that was skewed. In the end I purchased a monthly license of PFTrack and I succesfully tracked it there after doing like 1 or 2 tutorials so I have no idea whether I was doing something wrong in Cinema or maybe is this footage somehow too difficult for Cinema to track? There's the entire video in the Videos_Pexel.com folder.
8. There'a a Street folder with a street that I wanted to track but again each time the perspective was off. I also showed there how different it can look after simply changing the position constraint (the problem that I mentioned in my 1st question)
9. Folder Recordings shows what happens when I change either position constraints (again question number 1) ar planar constraints (question number 2), it also shows that something it doesn't snap to the features.
10. And folder Videos_Pexel.com containts 3 videos from Pexels.com and my question is - are there difficult to track? Maybe so far I've just tried to track videos that aren't easy?
Wow my answer turned into quite a long post so sorry for that but hopefully it's not that bad with all those numbers that I added and once again I'd be super thanful for your help
