It's bad practice to lock the morph keys by copying the first key to all the other keys. You're not only reducing the number of interpolated frames that way, but you're also blowing any future opportunity to rescale the overall time of the animation without having to screw around with all those keys. The reason why the morph started before frame 12 is because the default splined motion (for all keys) causes a little bit of undershoot and overshoot to happen unless you compensate for it. That applies to Position, Rotation, Scaling, Lighting, AND Morphing keys. This is explained in the reference manual on pages 8-33 through 8-36, and there's an entire tutorial (#12) about dealing with the same issue (as it applies to Position and Scaling). Morphing is no different. The correct way to start a splined motion precisely on a key is described in the Note about Key Bias on page 8-36 of the reference manual. And as it says in the second paragraph of page 8-34, "If you want completely linear motion (such as for a machine), set the continuity to 0…" Of course, if you want this to affect ALL keys (not just the one at frame 12, for example), you also turn on the G button beside it to make the continuity adjustment global. Simple! You only have to be a mutant to do it! – G
