Talk:Keyframe
From Synfig Studio :: Documentation
"Also it is a mark to a special frame where the information of every parameter in the animation is stored there in order to be reused later."
- No information is stored at all if you don't edit any parameter values. For example, make a scene, set the slider to 0s, arrange things, change the slider to 10s, arrange things again. You'll have a bunch of waypoints at 0s and 10s.
- Then add keyframes at 2, 4, 6, and 8s, save the file and look at the saved .sif. You'll not see any information at all about the values of the parameters at 2, 4, 6, or 8s; you'll only see information about the value at 0s and 10s. The values at 2, 4, 6, and 8s are calculated using interpolation, just like all other points in time between 0s and 10s.
- It's only when you edit parameters _after_ making a keyframe that information is stored about the value of the parameter at the keyframe(s). -- dooglus 20:11, 10 October 2007 (EDT)
"A keyframe could live all the time without any waypoint but it stores the information of the values of the parameters on that specific frame"
- There, you said it again. I suppose you can think of it as storing the information if you like. It doesn't really though. It's just a note that the information must be stored if anyone ever tries to change it by editing in 'neighboring' frames. -- dooglus 20:15, 10 October 2007 (EDT)
"If there is a waypoint there then the waypoint information is stored also (I have to verify this)"
- Waypoints are all that is stored to record animation information. The only thing stored about keyframes are their positions in time (2,4,6,8s) and their names. -- dooglus 20:18, 10 October 2007 (EDT)
