Overlapping transition: two shots dissolve into each other rather than cut hard — creates fluid passage. Classic in montage and bridging moments.
You're in the edit suite and realize a hard cut between two shots just isn't working – the energy drops, the rhythm falters. This is where Folding comes in: instead of ending the first shot abruptly, you gently cross-fade it into the next. Both images exist on the timeline simultaneously for a moment before the first completely fades out. This creates a fluid, almost liquid sense of transition – less abrupt than a cut, less cliché than a classic dissolve.
In practice, you'll work with two overlapping video tracks in your NLE (Nonlinear Editor): the outgoing shot on top, the incoming shot below. You'll set a short fade-out on track 1 and simultaneously a fade-in on track 2 – both keyframes running in parallel. The length of this cross-fade is crucial: 8–12 frames feel subtle and modern, 24–30 frames feel intentionally poetic. Too long, and you lose energy; too short, and the effect dissipates. Folding works particularly well when the two images "speak" to each other thematically or visually – similar color palettes, spatial continuity, or a thematic connection enhance the effect.
You'll typically see Folding in montage sequences: quick cuts between everyday moments, training sequences, or atmospheric transitions between scenes. The technique also works perfectly for voice-over passages or music videos where you consciously want to add smoothness to the editing rhythm. But be careful: folding too often can look unprofessional – the line between deliberate design and beginner's mistake is thin. Hard cuts and folds should balance each other in the edit, otherwise the entire sequence will feel washed out.
A practical tip: look at the motion energy. If a shot starts with fast movement and the previous one fades out slowly, Folding masks this discrepancy – ideal for elegant transitions. Also, use Folding to hide minor editing errors: a slight positional jump between shot and reverse shot disappears in the cross-fade. This technique costs you nothing on set – it relies on good editing and the right sense of timing.
