Frame Range
Frame Range panel.
This panel defines how long an animation will last in terms of frames. Frames can be divided by the scene’s Frame Rate to get the animation duration in terms of time. For example, a 250 frame animation at a frame rate of 30 will last 8.3 seconds.
Frame Start, End
Set the Start and End frames for Rendering Animations.
Step
Controls the number of frames to advance by for each frame in the timeline.
Time Stretching
Use to remap the length of an animation; making it run slower or faster. The Old and New settings may either be used as absolute values or as a ratio: For example, setting Old to a value of 2 and New to 1 will run the animation twice as fast.
Warning
Using Time Stretching will not influence the Start or End frames set above, so make sure that your animation is not cut off or has extraneous still frames at the end.
Old
The length in frames of the original animation.
New
The length in frames the new animation will last.
