Its a good skill to know. In real production you don't always get footage with convenient tracking markers, so you have to wing it and do it the hard way.
there is and it's called object tracking. Issue is that you need at least 8 trackers on your object which is ridiculous. This is really just a tutorial on manual object tracking. Technically you could try speeding this up by running trackers on the 2 markers, using their position data to create a simple 1 bone rig that moves the sphere, and change scale with an expression and some drivers.
I used a single dot the ball and use the montion tracking tab to get a single tracking point on that dot, add a sphere, set the origin of the sphere to the empty track and boom location has been taken care of, now i just have to manually set the rotation, it works really well tho
Wow, this music is way too intense for a technically oriented- *"This is some of my favorite background music"* I can see we're growing apart, CGMatter... we're definitely growing apart.
I think this is the kind of thing that separates the CGMatter videos from the Default Cube videos. CGMatter is meant to create intrigue into various things you can do in Blender, Default Cube takes its time and breaks things down. At least that's my take on it.
This is a nice quick overview of the process, particularly the compositing, but suffers from 1 common error - you should not be changing scale unless the photographed object actually changed scale in the shot. It seems convenient, but you should always try to match the REALITY of the scene. The main reason is that you cannot properly match lighting, cast-shadows, and environmental interaction if your object is not moving accurately through space, at the proper scale. Sure, its more difficult to account for 3 more axes of motion, but that is the nature of the problem. Also, you are correct to break the sequence into large intervals, but you should find the extremes of position and key those first. Then break the intervals into powers of 2, such as starting at 64 or 32, depending on the length of the shot. Then continue breaking the intervals down by a factor of 2 until you are down to a singe frame between keys. Its common to build a rig with the Z-depth axis oriented to the camera - that will account for your apparent change in scale. Then you can choose a point, track that, and lock the object local X,Y position to that point. Then you are left with rotations, which are oriented around the single tracked point. The Z-depth axis passes through the tracked point as well.
In particular, a linear movement in z direction will require a non-linear movement along the "scale axis". Using scale can be considered quick and dirty for not so much (and more erratic) depth change in the scene and no intersction with other objects
You would be right if he were needing to rerender lighting to match the original scene, but his method more or less overlays the original lighting onto the new footage
@@aliensoup2420 the lighting comes from the scene and compositing, if CGmatter used lamps to approximate the lighting then the movement would be necessary
Senior Roto Artist here, It's easier if you were to analyse the footage then figure out your key poses and mark those down, then fill in the ease and outs in between your key poses. Then you pretty much got a full track without having to do by 20s or 10s. It's much easier if you look at roto/matchmoving from an animator perspective. As animation is and always will be a study of physics and movement. I'm sure you knew that but you prob didn't want to spend 10 mins explaining how animation works LOL. Also feels bad when most big studios already have a matchmoving software xDDD we're spoiled.
I wanted to say this too, also in Blender you got the Animation curves witch are easy to edit, with view keyframes you can match the motion of your complete footage.
@@aronseptianto8142 try pftrack or syntheyes pftrack has 'better' interface and easy to solve for easy ones but it total shit when you have a muddy shaky shot lol
Professional compositor here, so I've done my fair share of roto in my time; Keying every 20 or so frames is great. Even better is key the start frame, then the end frame, then the middle, and keep subdividing that way. Even better than that, and what I do on every rotoshape or anything I'm tracking manually, is do the first and last frames, and then keyframe the key-poses. Say the ball starts at the bottom of frame, goes up, and then down again. You would put a key at the extents of each of those motions. Depending on the motion, I will then usually put a key a few frames after/before those initial keyframes, to nudge the object forward a bit while it is still slowly accelerating to its next pose. That usually captures the ease in/ease out that real natural motion has. Then I will start to subdivide the keys, and get down to frame by frame level if need be.
Now show us how to track camera footage perfectly aligned into a 3D LiDAR Scan of the scene in the footage (and render the two together with some transparency or something). I can provide data if you want...?
But by just scaling the balls and not tracking them in 3D you are limited in the interaction between them, aren't you? So if you use Metaballs and put them together and hold one ball behind the other in the video what will happen is, that they will melt together even though they are fairly far apart depthwise in the video, since in Blender they are just a big and a small ball next to each other.
what if instead of scaling the sphere, you set the 3d cursor to the camera position, set the 3d cursor as the origin of transformations, and set it to only change location? Then you would have the sphere moving in 3d space at least.
Why would you use scale instead of depth to track? Using scale, you won’t be able to add proper shadows and shading, and your texture mapping will be inaccurate because the amount of the front of the sphere you see vs the peripherals changes with depth. In more extreme cases you will not be able to track rotation properly once you use this workflow. Is there a reason why you didn’t use software tracking or is it just not available on your editing platform? Manual tracking is not great not just because of all the work, but it jitters too much most of the time.
LOL, what about OBJECT tracking? :) I think there is not longer path that rotoscopy. Of maybe if you paint all of this in paint, this will be pain(t)fully longer, buttt.... OBJECT TRACKING!!! YES, O.B.J.E.C.T T.RRRRRR.A.C.K.I.N.G!!! :) And why so offensive? :)
Object tracking will not work unless you have 8 trackers visible on the object in every frame. And even if you do that, you'll be tracking a "cage" of points on the surface, and will still need a way to find the origin of the sphere in the centre of the cage.
After effects can get a planar track with Mocha AE. But for full 3D object tracking you'd need something like Nuke. which is about $2,000 every 4 months
@@WolfDeity You can do it in blender too, the problem is actually the lack of points, you need at least 8, they wouldn't fit. Doing it manually it's not as bad as it sounds.
Stay with blue or green, digital cameras have double resolution for green because of the bayer filter, blue is not too bad because the color is very far from humam color scheeme
No FUCK** clue what you ment by all that, cause you had me at alpha mask but lost me at blue balls. No, but seriously, I just thought I'd blurt out and confess, regardless of my overly self medicated cognizant inability, that you are absolutely by far my favorite content provider in this hell hole.... and once again, I find myself laughing literally to the point of crying at your surgically exicuted closure . Really should consider sponsoring one of those 11 step programs. Btw what are those things -your wearing?
Nothing about sphere. But is there no way to use 2 point or 4 point tracking? I worked for 2 days, trying to find a way to make 4 point tracking work. All points tracked, Just can't set the tracking to scene.
Just because this video simply exists is the reason why my IQ is never gonna be above -100. You think your kinda smart and then this guy slaps this video on UA-cam to make you feel like a 3 year old learning trigonometry. Good video though I enjoyed it even if most of the information provided was too much for me to handle.
thats not a tutorial but to show off your skills. Pretty useless for beginners. As I know that you dont give a sh*t about comments, I dont bother to comment any further. But still prety impressive :D
I can't recall what movie, but it was cheaper to blow up real airplane than make everything in CGI, if just spinning a ball so hard and time consuming, I understand now.
Also using shortcuts will save you time....... Just Alt + mouse scroll wheel to scroll between frames or arrow keys, and hit the Record button to automatically insert keyframes
I don't know what half of this means, but I've been reccomended this at least four times now. So, I'm going to nod and pretend I understand, because I have to respect how much work this video took.
I think it require at least 4 points to determine orientation, but also distance from the camera. I tried something similar, but after linking empties to a track, all empties are in single plane. Now, important question - is there a way (maybe python programming) to move object or empties based of the space between them? For example, if object is closer, empties are more spread apart, if far, then empties are closer each to other. Four markers (and four empties) for four corners of the image, then some mathematics approach to reconstruct depth data? If distance between original points are known, then we should be able to use this data to reconstruct the distance between each point and the camera, not only from each to other.
What you are describing is auto-tracking software that already exists in Blender. Yes, if you have sufficient data, use an auto-tracking algorithm - but the point of this video is how to do something when you don't have sufficient data to use auto-tracking.
