Yes, I tried something like this last year but couldn't get what I wanted. Ideally all I should need to do is rotate the camera with the anchor point on the subject - however I don't think keyframing works with camera rotations very well.


I understand that you are asking for a feature here and not a workaround. But I'm a workaround-a-holic, so that's my approach to everything. ;-)

For anyone who might want to try this before the feature gets added:

It wouldn't really HAVE to be a camera move that rotates about a point in space... I find the keyframed camera moves to work REALLY well! You can move the camera to a new location and line up the scene to look exactly as you want before you set the keyframe.

Since moves between keyframes are interpolated, scrub through the area between keyframes, and if the camera view starts to stray, manually correct it and set a new keyframe at the halfway point.

Using that approach you can keep the camera's attention focused pretty well on the center of a scene. Start with just start and end. Then keep adding keyframes at the halfway point that redirects the camera, and after about 5 keyframes you should be pretty darn close.]]> Sat, 12 Dec 2015 18:29:46 GMT http://www.muvizu.com/Forum/topic5349-bullet-time.aspx Message from MrDrWho13 simonheffer wrote:

I have asked for the rotation point to be added, but the staff didn't see much use for it so didn't have it at the top of the to-do list.]]> Fri, 11 Dec 2015 23:10:51 GMT http://www.muvizu.com/Forum/topic5349-bullet-time.aspx Message from simonheffer Yes, I tried something like this last year but couldn't get what I wanted.

1) create your action scene as usual, using 2 cameras (one that shows the scene at the start of the camera's orbit, the other that shows the scene at the end of the camera's orbit). Halfway through the scene, change the camera view.

2) at the point in the sequence where you want the camera to orbit, (where you changed the camera view) take a screen shot of both camera views so you can recreate the scene from both camera angles (with gravity turned off, so objects and people can be suspended in space)

3) using this still scene, make a separate action sequence which starts with the camera view seeing exactly what your first screen shot saw, and using keyframes, move the camera to a position where it sees exactly what your 2nd screen shot saw.

4) when you merge your scenes, insert this sequence in the middle of your original action sequence at the point where the camera view changed.]]> Thu, 10 Dec 2015 14:53:26 GMT http://www.muvizu.com/Forum/topic5349-bullet-time.aspx Message from simonheffer . I'm thinking we just need a way to record ONLY camera movement whilst the rest of the scene is frozen.]]> Thu, 10 Dec 2015 14:20:04 GMT
