At this time, there is no way I know of to track live footage in AE and then to export the camera data to Blender as a matter of routine.  But, there is an interesting cheat that works very well in many situations.  I present it here as I know many have asked and the answers are all over the place.  Open the footage in AE and do a normal 3D camera track.  Set up the ground plane, etc. to get the AE camera fully aligned.  AE is ready to go as soon and the tracking is setup to enable a good target layer to be locked down.  Then, make a small (100 X 100 px) solid and lock it on a solid AE track point.  Make several more of these spread near and far and use enough that no frame goes by without at least 8 widely distributed.  Render out the footage and import it to Blender.  Set up the Blender 3D camera track manually with track markers covering each of the little AE solids.  Run the Blender tracker and voila.  Blender 3D camera movement will follow the live action perfectly.  Comments are welcome.  Good luck.

I just got Adobe After Effects CC with Cinema 4D lite.  I use Blender for 3d animation and I don't want to switch to C4D. Is there any way to export After Effects camera movement to Blender?

I have searched but not found an answer that exactly answers or works.  I have a rotating rendered head animation that I want to export with a transparent background so I can import into final cut pro x and lay over video footage or still imagery. I have tried saving as a blender render as quicktime .mov with alpha as transparent and as RGBA but doesnt work, a black BG. I have also tried as a cycles render but still black BG. Is there any particular file format that is better for this? H.264, MPEG, .mov? or something I am missing? thanks

I have an issue when generating an image sequence from a video clip. Pictures 1,2,and 3 are three consecutive images from a video clip. Picture 4 is a close-up of the heel of one of them. The camera is on a tripod. As you can see there is no issue with the brick wall, but with any moving part there is. The camera is a Panasonic HDC-SD100. The clip is AVCHD 1920/1080. If I use VLC to extract the image sequence there is no issue. I use all the default settings except for the rendering resolution which I set to 100% and image compression to 0%. I have the issue with Blender 2.79b and 2.80. With this image issue it is impossible to do camera tracking. Any ideas what I need to do in order to solve this. Best regards.

I have a tunnel that I want a camera to go through, and want to replace the armature with a curve so it moves exactly on that path. I'd like the camera to also rotate to follow the bends of the tunnel. Using cycles.   Appreciate it, the problem I'm having now is that the camera follows the path, but after each turn, kind of snaps back or bumps, like a recoil of sorts. I reduced the size of the turns, but it still happens. And within the graph editor I can't change the interpolation mode, it's all greyed out. The only reason it looks kind of decent is because the camera is set to 15mm. Any ideas?

If just need to crop Audio/Video from a longer track, what can I use? I tried OpenShot, but I find the export video slow, perhaps its compling all the "layers" into a new movie? Perhaps I just need a simple "crop" tool for audio/video will surfice?

Whenever I do camera tracking in Blender the reconstruction is always zooming out or not on the axis. I have a great quality camera, but the end results of the camera tracking always has the model sliding. If you have a solution please tell me.

What are the typical situations where you should use AE for locking exposure?

Often I want to just point the camera to an object or a specific area in my scene to get an idea of how it'll look in the render. What's the most painless hassle-free way to do this in blender?  A quick search on the blender wiki does not lend itself to easy look-up due to all the noise in the search result.  This question could probably be broken down into these two main questions:   How do I point a selected camera to the current 3d-cursor location in the scene? How do I point the selected camera to the currently selected object(s) in the scene?

First, I'm a newb to tracking.  That said, I tracked my scene with a .3 solve rate. I dropped in a cube and rendered out a short animation... looked great.  I readjusted the position of my cube... nothing more... and now my track is broken.  All tracking points were locked, I did not resolve the scene... just suddenly my object is wobbling all over in the render.  Going back to my LOCKED tracking points, they are no longer staying put.  Anyone else seen this?  Has happened on 2 machines, same reproduction steps. This last one was first time I tried locking the tracking points.  Memory issue?    Thanks...

I've found a number of how-tos for solving video but I'm just looking to put an element in a photo and can't seem to find a how-to for that.  Is it possible in blender to do a camera solve with a still image?  Thanks.

I'm trying to do object tracking using Blender 2.71. In a youtube video the guy simply clicks "Object Motion" in the Solve tab.  His Screen:    My screen:    But I can't find this option.    Can anyone help me please?

Is it possible to achieve a result like this using Blender, where the trail of the ball is drawn on the video?   (Screen capture from the video)   I've only really used blender for video editing, so any pointers are much appreciated. I was able to track the bowling ball for a few frames but as it got smaller I had to create a new marker and resize (any way to overcome that?)  Finally, I'm not sure what steps to take after I've tracked the ball in order to render the line on top of the view.

I started using Blender couple of weeks ago to edit some of my video clips. Spent quite a while editing this one, and everything worked fine. Video rendered as it should. The whole project consists of a MP4 file with a whole lot of soft cuts. Came back to it a couple days later and now the preview won't show a thing. When I render the scene, it's just a black screen with no sound.  The original file is still working, as well as my other Blender projects. And the weirdest thing is that if I add a new movie clip to the project, the preview works just fine for that clip.  Can anyone guess what might have caused this? I've googled like crazy and haven't found anything helpful.

I am trying to export markers from the Blender motion tracker and found the following script that will do exactly that:  for clip in D.movieclips:     for track in clip.tracking.tracks:         fn = 'data/tr_{0}_{1}.csv'.format(clip.name.split('.')[0], track.name)         with open(fn, 'w') as f:             frameno = 0             while True:                 markerAtFrame = track.markers.find_frame(frameno)                 if not markerAtFrame:                     break                 frameno += 1                 coords = markerAtFrame.co.xy                 f.write('{0} {1}\n'.format(coords[0], coords[1]))   It works but I have two questions:   How can I save the data on my Desktop rather than in folder in MacOS blender content where it saved right now. The following won't work:   fn = '/User/me/Desktop/data/tr_{0}_{1}.csv'.format(clip.name.split('.')[0], track.name) The resulting values I get do not represent the more user friendly marker values in den Blender GUI. Instead of x/y coordinates in screen coordinates, I get a value between 0/1. How can I convert them to those screen coordinates ?    Thanks for your help

When I import a video in blender, I get audio and video on two separate channels.  And beside the name displayed on the channel I get some number:  video name: path | number I am talking about  The numbers in both the audio and video channel, do they have to match? The guy in a youtube video tries to match them by changing fps, and they match for him. But I can't get them to match.   So, do they have to match? How can I do it? Would there be any problem if they don't?

My problem is that I have a huge scene with meshes and (let's say) I see this scene for the first time. I do not know it, I want to look around. I can use the controls like MMB  plus look around, ⇧ Shift + RMB  (but scene is too huge for this). Then I select some objects on the hierarchy and press numpad . (but as I said: I do not know the scene and/or the object names can look like all the same as well), what will take me there. I know, I can use the fly camera mode, but that is well... kinda hard to use, for me at least. Is there a better way to move around? Like in a game: WASD + mouse look? (I do not want to move my camera, my goal is to move my editing area to a specific position / angle)

i have a 3D Object and want to add a background image( if possible even a movie) to this 3D Object. I use Cycles to render and tried a plane with the  image as texture. When i go into render mode, it looks like this(picture with background) and when rendered, it has no background. The key also looks into  a different direction.  Should i even use Cycles for this or use motion tracking? i tried to use that but had several problems.     Rendered mode   When scene is rendered
