Can't apply an effect

[PosadaPhotography]

Hi everyone. I have a sequence where I'm now adding video and audio transitions. Sometimes I'm able to drag/drop to span two clips, and sometimes it will only allow to be applied to one side.

Can someone explain what it is that is causing that?

You need to have extra media on each clip for handles.  If no handles exist, it may not let you drag it there.

• If one of the clips has handles, Premiere will automatically align the transition on the other clip rather than the edit point.

How close to the lead frame of the second clip there are you? Typically this issue occurs when you don't have enough 'handles' ... unused frames at the beginning of a clip in this case.

The little triangle in the upper corner that indicates the first frame of a clip is missing, so I cant tell you are at least not on the first frame. But ... how many frames to the left of the in-point are there?

If more than say 15, then ... this shouldn't happen. Normally.
