Trends with names. Cuts that land. Lign sits in front of CapCut and does the alignment grind for you.
The wedding sunglasses trend, without the 53-photo CapCut night.
Brides and content creators ride the trend on TikTok with hand-aligned frames. Lign aligns them automatically.

The pain
I took 53 photos, each photo at 0.1 seconds & duplicated until they aligned with the sound.
How Lign solves it
The features that line up for this exact use case.
-
Object Anchor: tap the sunglasses, watch Lign do the rest
The Object Anchor mode uses Apple Vision instance segmentation plus a feature print to find the same object across every photo. Tap the sunglasses on one frame; Lign rotates, scales, and translates the other frames until the lenses land on the same pixel.
-
Animal pose detection for dogs and cats
For the puppy-to-adult morph: Animal Eyes is the primary landmark, with Animal Nose Tip and the pose joints as fallbacks. Apple Vision detects all of them on dogs and cats from iOS 18 onward. Works on rescue arcs, kitten-to-cat, anything four-legged.
-
Beat-friendly timing baked into the export
Set per-photo duration in tenths of a second so the cut lands on the drop. Loop count to repeat the morph two or three times for Reels. Hold-last-photo to let the final shot sit while the audio resolves. Export 9:16 for vertical, 1:1 for the grid, or Original to keep wedding-photographer framing.
The trend has a real production cost. Content creators charge several hundred per event, and full wedding-content packages run into the low thousands, specifically because the post-production is hand-aligned. Brides who DIY end up with the @deardiarysocial workflow she described in her own viral breakdown: “I took 53 photos, each photo at 0.1 seconds & duplicated until they aligned with the sound.”
That hand-alignment step is the entire reason Lign exists.
Lign’s Object Anchor mode lets you tap the sunglasses on the reference photo. Apple’s Vision framework isolates the object via instance-mask segmentation, generates a feature print, and finds the matching object in every other frame. From there, every photo is scaled, rotated, and translated until the sunglasses sit in the exact same place. Export 9:16 for Reels and Stories, or 1:1 for the feed.
The result is what the trend is supposed to look like: sunglasses anchored on the beat, faces moving underneath, no CapCut night.
Landmarks used
- Object Anchor (the sunglasses)
- Manual landmark (two anchor points on the lenses)
- Pupils (faces beneath)

Two ways to see what alignment buys you.
Drag the slider for the still comparison; scrub the flipbook for the motion. The frames here are stand-ins drawn from the in-app pet morph; the use-case capture lands with Phase 8.5.
About that one thing
Can I do this without CapCut?
Yes. The whole point of Lign is that the photos arrive at CapCut already lined up, so the morph template actually works on the first try. If you want to skip CapCut entirely, export a 9:16 or 1:1 video from Lign directly; the loop count and per-photo duration are part of the export settings. Drop it into Reels, Stories, or the TikTok composer with audio on top.
Questions, answered.
- What's the wedding sunglasses trend?
- Brides and wedding parties wear monogrammed or heart-shaped sunglasses, take thirty to sixty portraits at a tenth of a second each, and cut the frames into a fast morph where the glasses appear to 'dance' on the beat. The trend lives under #weddingsunglasstrend, #puttheseonandpose, and #heartsunglasses on TikTok and Instagram, with 'Day N Nite' by the Crookers Remix as the anchor audio.
- Why does manual alignment ruin it?
- Every photo is framed slightly differently. The sunglasses sit at a different angle, the head is slightly tilted, the camera is closer or further. CapCut's morph template only works if the frames already line up. Most brides spend an evening duplicating frames in tenth-of-a-second slots until the glasses settle on the same point.
- What does Lign do here?
- Tap one frame to pick the sunglasses as the alignment anchor (Object Anchor mode). Lign then locks every other photo to that anchor, scales and rotates each frame, and exports a square or 9:16 morph video that lands on the beat. The 53-photo manual chore disappears.
