With the CameraViewport component from the palette, its easy to set up an interactive previz of our scene. I recommend to use only the pixelmap as input to the previz and have all other rendering and animation happen outside of that.
A very useful addition to any previz is a Screenshot button and at a later stage, this could hold parameters of the scene and the recording interface. If you turn the ‘Unique Suffix’ Option on, each image will automatically get a rising sequence number and you can not unvoluntary overwrite files.
