In this video, you will learn how to use the 3D Camera Tracking and properly place objects and VFX in the environment. Here are the project files for you to practice: www.dropbox.com/sh/jgk9ampi65...
This is what I like to see in a video tutorial right here, clear and brief examples on a subject without silly comments and distracting personalities. I hope to see more of these
Cheers for this. AE must have changed quite a bit since I last tried this, tracking was a terrible experience. This worked with test footage in a badly lit room, first go.
Ahh I thought you would have to export the camera to max and render, but I see you are rendering your alien in your 3D software first and then adding it. I never thought of doing it this way.
Yep! You can do it in this way to save some time. You can also export depth maps, AO channels, etc to make the compositing look more "3D" and realistic.
@@DIGAHub Yeh that is good to know. By the way did you know if you export as EXR you don't need to key out the green background, as you have an alpha channel. Well if you do it from 3ds max anyway. Only thing is that EXRs can be rather large
This is the shortest and best tutorial I have watched on Camera tracking! Please make one more video on using Element 3D tracking. Thanks. Is that model free anywhere?
@@irshadayoob3720 That model is a Xenomorph character. I didn't see the model is free anywhere, but here's a cheap one: www.cgtrader.com/3d-models/animals/dinosaur/xenomorph-6d1d0866-ae27-4c5a-b8fc-2a1f9a6e4fae
Hi, Check video at 1:48. Make sure to move the object's anchor point to the bottom of the object (where the object is supposed to touch the ground) before you make the object a 3D layer and change its positions. This should fix that.
i have the exact same settings as yours. i'm using ae 2022, but i been having this problem for ever. each time i analize the video and then i leave the background layer with the 3d camera and then come back to it. it starts to re analize all over again. this is each time i go to a new layer and come back to the 3d tracker camera... is there way or how can i have it only analize the footage once. and be able to go back and see all the tracking dots again..
Hi, after you've done analyzing 3d camera tracking the first time, the tracking data will be stored under the effect of your BG layer. To see all the tracking dots again, go select the BG layer, hit "E" key (for effects), and select (or double click) the 3D Camera effect and those dots will appear again.
@@DIGAHub hi and thanks for yuor reply, i did exactly as you mentioned. and i have the exact same settings as you. but it still re analizes the whole clip again. perhaps is there any type of settings i have to disable/enable?
@@fibstudiovfx I never heard about this issue before. The only thing I can guess is maybe you have a shortcut or something triggered the "Reset" button under the "3D Camera Tracker". Every time you hit Reset, the camera will analyze everything again. If you find out the issue, please share it at here so other people may find it helpful.
Check off the 3D layer of the character. Make sure the anchor point is on the character's foot (You can use the Pan Behind tool to adjust it). Then, check the 3D layer back on. Copy your tracking Null's position and paste to the character's position. Now it should work.
What happens if there are no tracking points where you want to place the object? For example, if I wanted that alien to be on the grass somewhere but there are no tracking points there?
Hi! You can select the closest tracking points to create a Null, then place the object on the Null. Then you can move the object along Z (the blue arrow) and X (the red arrow) until it is on the grass, just like how you would move a object in 3d software or in real life.
I have subscribed but it hard for me to understand this tutorial ...I wish I could have understood how to shoot video with moving camera then I do green screen visual effects...I will keep on watching this video till I understand your tutorial
Hello, You can right click on the layer that you used keylight, select "Pre-Compose" (Move all attributes into new composition). Then, you can create masks on the Pre-Composed layer and it should work.
Hi there, Are you using the project files I provided for tracking? If so, you may accidentally changed the scale or position of the video in the composition, causing After Effects failed to analyze the video. 0:22 Select the BG video, drop it to create a new composition again. Do not move or scale the BG video. 0:36 Go apply the Track Camera directly. Following that, you shouldn't have the issue again. If you are tracking your own video and the "Analysis Solve Failed", here are two possible reasons: (1) Video is blurry or the video has a poor contrast, so After Effects can't find enough points in the video for tracking (2) the camera movement is too intense.
@@p0rtalraider214 Hi, (1) Make sure your preview window is set to the composition of the tracked footage, not the layer.(See the tabs on top of preview window). (2) Place the Anchor Point of the 3D model layer to the feet of the character model before change that layer to a 3D layer.
@@DIGAHub Hi it's me again! I've learned a lot from your Vids thank you so much. After tracking and adding the 3D model, it was working fine until I noticed the model was shifting from place a little and seemed to be floating instead of looking like it was placed on the table. I printed tracking markers and tracked the footage thinking it might solve my issue but did not. Please help me out or please make a video..🙏🙏
