Technique is hard to fix blind. Video analysis puts clip next to clip — say your shot today and a month ago — and you see exactly what changed.
Both clips run on a shared timeline, so you align them to the same moment. A full-width timeline bar, spacebar control, add a second clip in one tap. It even works with iPhone formats (HEVC).
