    When working for the first time with timeline Track Offsets - `Apply Scene Offsets` and `Apply Transform Offsets` in AnimationTrack gave me a lot of frustration.
    Documentation doesn't mention them yet.
    After digging through forum, creating separate sandbox project and playing around with simple animations and timeline I got better grasp of their meaning. Please correct me if I make mistake in explanation.

    First problem I'd say that `Scene Offset` term is misleading since it's talking about Transform's world position, and `Transform Offset` is ambiguous because it's not clear whether it's local or world transform values.
    I would suggest using terms something like "World Transform Offsets", "Local Transform Offsets".

    Second problem is `Apply` meaning.
    In `Apply Scene Offsets` it reads current local position and adds this offset to track clips. As a result, bound object moves from same world position at first frame.
    In `Apply Transform Offsets` it adds user defined offset to track clips. As a result, bound object's transform.localPosition is set to the offset values at first frame (and may look like bound object teleported).
    By the behavior of `Apply` options could be renamed to `Read Local Transform Offsets` and `Set Local Transform Offsets`.
    If `Apply` can't be changed to better alternative my request would be to provide some infobox in inspector better describing how selected option influences animation.

    Thanks
