Creating animations

When I make a scene 1, in front of a box, and then scene 2 inside the box - can I somehow export this to an animation, or do I need to create hundreds of scenes in order to capture it? I want to make a movie going from the front of the box, and ending inside, not just snapshots from the two angles. I have read the tutorial, and cant seem to find any information about it.

Use one of the scripts from the client area, depending on your host application wether its blender, xsi, max you can load everything automaticly from within the app and render animation.

The way you export an animation from Sketchup is 'by scene' tab so you do need several intermediate scenes between the start and the end to get a smooth animation.
A basic built-in Sketchup animation exports as a movie file format or series of images - the 'intermediate frames' are made for you - the render quality is generally 'low'. The more frame-scenes you have the less jerky the animation.
When you use the 'Octane Render Sketchup Exporter' to make an animation first you need to set up your rendering for one frame and save it, then make the animation frames, and you will get one good quality image per scene that you have specified.
There are several free [or inexpensive] Sketchup 3rd party tools to help you get the several intermediate scene tabs made to give an acceptably smooth sequence of images - like RickW's 'flightpath' [ ] or Chris Fullmer's CameraRecorder [ ]...
The preceding part covers animating the camera - there are other tools that 'animate objects' by making copies of them onto various layers that are on/off in sequential tabs etc... and thereby give the illusion of the object moving as well as the camera as the scenes change...
So one way or another you now have sufficient intermediate scenes made...
You then export your Octane animation frames using the desired 'start' and 'end' scene tabs [step=1] with each exported image is rendered in turn , with an incrementing suffix added onto its file name. This can take a long time if a set of hi-res/large images are exported.
Note that you don't need to do the more time consuming option of "export separate OBJ/MTL files for every frame" UNLESS you have used 'object animation' affects by layer manipulation that require it etc...
Once you have all of the images made you then need to assemble them into a movie format using a tool like 'Windows Movie Maker' [that's free and there are many others]. It takes the set of images as 'key-frames' and [depending on your settings] adds several extra images between each pair of key-frames - these intermediate images are 'betweened' from the pair - this will give a smoothly animated effect... You then export into the desired movie format.
Once you have the movie file you can edit it further to add titles, fade-in/out effects etc using other free tools available...
You now have your Octane Rendered animation movie. :D
