Has someone who used mainly adobe products i've create some notes i'll leave here that might help some other users who are trying C3 and are a little lost on how to do the "simple things".
Animate object (manual):
Expected - click object in layout, create keyframe for start, navigate timeline, move object to desired position (creates/updates keyframes), repeat as needed.
C3 steps - add instance of object to timeline, add object X and object Y, enter editing mode, create keyframe for X and/or Y and update value, create more keyframes and update values.
Similar steps for common properties like: size, opacity, color, angle, etc. Import object add the properties and then change them in keyframes on the property layer.
Add audio:
Expected - choose a timeline location, create keyframe chose to add audio and set type of playback (start, stop, stream) and any effects (channels, fades)
C3 steps - currently the audio é placed at the start of the timeline (can be delayed with the "start offset"), and is a "event/start" mode. (no stop or stream in timeline for now)
You can add a tag to the audio and then use regular audio events to modify it.
Animate object (code):
Expected - create keyframes (object layer or empty layer), write code for object x and y movement
C3 steps - (currently there is no "event sheet" per keyframe to set code to be run at that point, could use the variable trick below to trigger event blocks)
Preview timeline:
Expected - drag along the timeline and preview the objects changes on the layout (always previews, onion skinning on/off to help distingsh animated objects)
C3 steps - enter edit mode, hold ctrl, then dragging along the timeline will preview the objects changes on the layout (only previews in this steps, no visual guide of animated objects)
General notes
I find it easier to create a keyframe anywhere on the timeline (so a random time) and then change in it's properties to the correct time.
If you have a list of keyframes planned, you can create everyone close to start and then edit them to the correct times.
Haven't found a use for value tracks yet, especially since there doesn't seem to be a way to preview the value on the timeline. (even if you add a keyframe between two valued keyframes)
You can zoom below scale 1 in the timeline using ctrl + mouse scroll wheel
You can add variables to you objects, "animate" the values on timeline, and then use them on your events.
This was how i "animated" object effect parameters on my intro tests. youtube.com/watch
