How do you ship 9:16, 4:5, and 1:1 without a human recrop on every ad?

Ship 9:16, 4:5, and 1:1 without a human recrop on every ad by starting from the placement you will buy, locking kit and safe zones per ratio, then reframing siblings in assembly. eonik does that on Mac; you still watch each poster. CapCut auto-reframe is a crop, not a layout. Upload remains yours.

Execute the batch rendering script to generate all 3 aspect ratios simultaneously.

How do you ship 9:16, 4:5, and 1:1 without a human recrop on every ad?

Pick a source ratio from media, not habit

If spend is mostly Reels or TikTok, design 9:16 first. If LinkedIn, start 1:1 or 4:5. Widescreen-as-truth is how captions die.

List placements actually in the test. Do not export ratios you will not buy “just in case.”

Layout rules per ratio

Set type scale, logo lockup, caption band, and hook face region per ratio. 9:16 needs a larger bottom clear for UI; 1:1 can carry more type; 4:5 sits between.

Load those rules into kit. Reframe in eonik as a step, not as a Friday panic.

1. Pick the source ratio from placements you actually buy.
2. Lock layout rules per ratio in kit (type, logo, caption band).
3. Reframe siblings in eonik. Watch each poster full-screen on a phone.
4. Name files with ratio in the stem. Never leave CTA in chrome.

Keep the test honest

If ratio is the variable, lock hook and body. If hook is the variable, ship the same hook across ratios you will actually run, or you confound placement with opening.

Name files with ratio in the stem so Ads Manager mapping stays human.

Reframe: CapCut vs eonik

Job	Auto-reframe in CapCut	eonik siblings
Source of truth	Usually 16:9 master.	Placement you buy.
Type / logo	Often breaks.	Kit relaid; you check.
UI chrome	Easy to cover CTA.	Safe band per ratio.

What usually breaks

16:9 master as the only composition.
Exporting unused ratios and reading them as one test.
Skipping phone QA.

Consider the next cut. Make it in eonik on Mac, approve every frame, then upload yourself. The loop is how to generate AI ads. eonik never spends.

“On the average, five times as many people read the headline as read the body copy. When you have written your headline, you have spent eighty cents of your dollar.”
David OgilvyConfessions of an Advertising ManCampaign excerpt, Confessions of an Advertising Man

That principle still holds. The next on-brand cut is yours to approve.

Questions

Do we still need 16:9?

Only if you run it. Many paid-social cells never do. Start from the placement you will buy, not from a widescreen master. If spend is mostly Reels or TikTok, design 9:16 first; LinkedIn often wants 1:1 or 4:5; Exporting unused ratios “just in case” confounds the test; eonik reframes siblings; you still watch each poster; Upload remains yours.

Can this be fully automatic?

Reframe can be a step. Approval cannot. Watch the poster full-screen on a phone. CapCut auto-reframe is a crop, not a layout; Type and logo often break, and CTA sits under UI; Load safe bands per ratio into kit, then reframe in eonik; If a hook only works in 16:9, it is not a 9:16 hook: rewrite; Never leave CTA in chrome.

Does eonik post to every network?

No. You export files. eonik is the Mac app that relaids kit across 9:16, 4:5, and 1:1 siblings you approve. It never spends and never posts; Keep the test honest: if ratio is the variable, lock hook and body; if hook is the variable, ship the same hook across ratios you will actually run; Name files with ratio in the stem.
