How Do I Make Freeze Frames In A 3D Model. To Render It...Object In Motion...Freeze Frame In 2 Sections Or Spots Without A Separate Editor.
Thank You So Very Much...
 
The term Freeze Frame was first applied to live actors who would freeze in place to enhance drama.
Adopted for film and video it's essentially multiple copies of the same frame repeated.
The ultimate version may be in the Matrix where the motion freezes but the camera moves around a still scene.

For standard freeze frame just stop all object and camera motion for as many frames as you need.
 
* I suggest that this is a matter of post processing.
* Be it iMovie, DaVinci, Final Cut Pro or whatever.
* Of course, this does not work work for Matrix / Bullet Time trickery.
 
If you're rendering with Falcon or Cheetah + Radiosity then repeating a single frame to freeze motion will look wrong unless you render multiple times or add a noise layer in post. You can observe the problem in old movies when they'd freeze a frame vs. shoot a still scene and the film grain would freeze making it clear that the shot wasn't of a static scene, but a still photo (even if the camera pushed into it, or whatever).

If you do use a noise layer, you'll probably need to use it across the entire scene or it will still look weird.
 
Here's Gummie Guy jumping Matrix style.

* Bullet time uses significantly more complex methods. Simulating bullet time may be possible using a spline tracked camera, but days of extensive experimentation and precise fine-tuning would be required to make this work. Studying relevant takes of the Matrix frame-by-frame should help.
* In any case, you need a blue screen and a picture-in-picture composition in some video editor to get there.

* The primary creators were Paul Debevec (USC) and George Borshukov, both involved with the Matrix Trilogy. Their work is seminal for multiple aspects of virtual reality.
 
If it's all cgi, then no blue screen is needed.

The frozen pan/orbit of Trinity mid-kick in the Matrix was live action wire work, shot with a buttload of electronically controlled SLR cameras. The technique has nothing to do with VR and while there was likely some cgi post (to clean up wires etc.) it's really nothing to do with cgi either (maybe the background was cgi, more likely it was just a set shot using motion control to match the pan).

Here's a video where they show all this.

One issue with doing it in C3D is that the animation curves will be difficult to maintain across the frozen portion.

There´s no "frozen" frame in Matrix Trilogy - it´s super slow motion during the "camera orbiting".

The shot of Trinity jumping, to my eye, slows down to frozen (watch her leg)—which makes the effect even cooler.

In any event, the principle is the same.

The bullet-time shot of Neo is a pan/orbit of very slow motion. (Again, same principle, whether you freeze the action, slow it down, or whatever).

(There's also a scene where the world is frozen—shot in Martin Place in Sydney—except for actors moving through it, which is a completely different trick.)

A similar shot occurs in the (terrible) Lost in Space movie (I believe that shot is just frozen, and it's badly matched to the rest of the footage, unlike the Matrix shots which are perfect).
