I would suggest doing this by creating the transition clip first then adding the filters and keyframes to the transition clip not only because it will ensure that the effect happens but also because it’ll save time as you’d only have to be creating one set of keyframes rather than two. When I undid the transition clip after doing it the way you did, I checked the keyframes on the second clip and the overlapping of the two clips seems to have ruined the keyframes on the second clip which is probably why it wasn’t coming out right. By default this creates a video dissolve with audio cross-fade. Doing it the way you did which means adding the transition clip last doesn’t get me the same results.
