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.
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)
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)
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
