When you cut out the middle of someone talking in one spot, you get a jarring jump cut. A morph cut calculates the face movement and joins the two sides smoothly.
To trim a slip of the tongue or an "um" in an interview, lecture or YouTube talk video. It works best when the camera and background are locked. You can also use it deliberately between two different clips as a warping transition.
Use it where you cut a piece of dialogue out of an AI avatar or lip-sync video, or where you split one clip in two and shortened the middle. In Premiere Pro, place Video Transitions > Dissolve > Morph Cut from the Effects panel at the cut point and wait for the analysis to finish. In DaVinci Resolve, the Smooth Cut transition does the same job. Check it at the default length first; if it looks off, try making it shorter or longer. Faces warp easily where the head turns a lot or a hand passes in front of the face, so move the cut point. If you lock the camera from the generation stage with "static camera, locked-off shot", it is easier to join.
Smooth a jump cut in a talking-head clip by blending the last frames of part A into the first frames of part B. Use your editor's Morph Cut or Smooth Cut transition, or this short fallback for two 5-second parts: ffmpeg -i a.mp4 -i b.mp4 -filter_complex "[0:v][1:v]xfade=transition=fade:duration=0.1:offset=4.9[v];[0:a][1:a]acrossfade=d=0.1[a]" -map "[v]" -map "[a]" out.mp4
