Hi Dave,
Glad you're working through this project (and thanks for doing the MOOC).
Here is some general info that might help explain what you're seeing regarding Detail 1:
- 'Transitions' are stored in the 'To-Keyframe' (think of them as "how do I get to this end state")
- This means that Keyframe-1 doesn't have a transition at all (per your top screenshot)
- Which is why 'Transition' is grayed out in the UI (for that selected keyframe)
- Extra mini-note - animations don't run in Layout views (unless you activate the frame)
- I would recommend staying in the Map view exclusively when making an animation
- Transitions have sub-components: camera; time; range; layer
- Camera -> how the camera moves; Time -> how the time-slider moves; etc
- Transition sub-components can use different types of math for calculating how the value/s change
- EG: The camera-movement-transition can be 'Linear' (for straight line flight path)
- EG: The time-transition can be 'Stepped' (for a 'leap' to the next time)
- The top screenshot in my previous post shows how to change just the time sub-component
- The icon for the 'circle' shows in the Timeline Pane is for the camera transition subtype (only)
- And if your extent never changes, it won't matter what the transition type is for this component
- That is, don't worry about the displayed transition type for your animation
- The 'mixed mode' you're seeing is an advanced option, where you can change individual properties within a sub-component (eg: the 'X' coordinate of the camera can transition using 'Linear', while the 'Y' and 'Z' coordinates could transition using 'Fixed curve'). I'll expand a bit on how you (probably) got to this state a bit further down. It's pretty advanced animating, and not something you're likely to need to do on purpose.
So... on a practical level... the only transition sub-component you need to ensure is Stepped is 'Time'.
And the best way to do that for all the keyframes is to: select all keyframes in the Timeline pane (the one at the bottom of the view); click on one of the...
Regarding the 'mixed mode' result -> this was probably the result of changing the 'Transition' type in the Animation Properties pane (the one that appears on the side of the view) without selecting an entire section of properties. It's easiest to understand visually (per below) - for your use case, you want to select an entire section (per the right side) before you set the Transition type. I suspect you accidentally selected-and-edited a sub-component of the camera (per the left side).
The above info on mixed-mode just an FYI. None of this matters for an animation where the camera doesn't move. To get all the icons back to a single type (if you wanted to), select all the keyframes in the Timeline pane, click one of the icons, expand Camera, and pick a transition type (eg: Stepped).
Phew. Well, that was more info than I expected to put in for detail 1. Hopefully it's helpful for general knowledge.
Regarding Detail 2, I think you just need to update the Time extent for the last keyframe. It's possible / likely that the time-slider state was just captured incorrectly -> eg: with the std 5-year span, instead of the custom span needed for the final (non-5-yr) extent of the data.
Steps:
- Select the last keyframe (in the Animation Timeline pane)
- In the Time ribbon, update the 'Current Time' extent of the time-slider (screenshot below) as needed
- Note that the 'Full Extent' properties are basically data metadata, and are not used in the animation
- In the Animation ribbon, update the selected keyframe by clicking the 'Update' button in the Edit group
Tip: double-click on the second-last keyframe, and then again on the last-keyframe to zoom to a refreshed view of it -> the dynamic text should be updated to the new 'end' time value.
Hope this gets you to where you need to be!
Thanks, Nathan.
