There’s a couple ways to do it.
A. Curve modifiers (add cycle modifier)
In the Graph Editor (GE), select the 2 channels on the left so they are highlighted and press CTRL SHIFT M (inside the part of the window that has the curves in it) and chose ‘Cycle Modifier’.
(you can also do this one curve at a time with the properties panel in the ‘modifiers’ tab by pressing ‘add modifier’)
Then end your animation 1 frame before the 6th loop.
(scrub to that frame and press E over the time line window, or type the frame number in the end frame)
Then render the viewport animation. There is no need to ‘render’ it properly.
B. Render once from Blender and duplicate the output.
Render (opengl) the cycle once and then duplicate this video 4 more times using the Video Sequence Editor (VSE) or any other video editing software. Make sure you stop 1 frame before the cycle repeats, otherwise it will pause on frame 1 because it is showing it twice.
C. Duplicate the keyframes.
You can use SHIFT D in either the Graph Editor or the Action Editor to duplicate the keyframes and repeat it 4 more times.
Change the animation end frame to 1 frame before the 6th cycle.
