Regarding the Creation of Transition Animations Between Start and End Frames

[cgfans007]

I created a first-last frame animation, but the animation itself has no connection whatsoever with the two starting and ending images. It's an entirely newly created video. It seems that this 'first-last frame' feature isn't working properly at the moment. Or, are there any key prompt words to trigger it?

Im seeing the same thing - it seems to be doing a text-to-video for the fill option instead of using image-to-video with the start/end frames.
