Are TikTok, Reels and Shorts all the same 9:16 aspect ratio?

Aspect ratio yes (9:16), but the safe zones differ. TikTok overlays a username and like-button stack on the right; Reels overlays a caption bar at the bottom; Shorts has a different bottom-of-screen control area. AdLit's exports respect each safe zone so your content isn't hidden.

What's the length limit per platform?

TikTok: up to 10 minutes (though best performance is 7-30 seconds). Reels: 90 seconds. Shorts: 60 seconds. AdLit's default render targets 15-30 seconds (the empirically best-performing range), but you can request up to each platform's max.

Can I export the same video formatted per platform automatically?

Yes — a single Shorts job exports three variants: TikTok-optimized, Reels-optimized, Shorts-optimized. Same content, different safe zones and caption placements. Most teams batch the export and upload to all three platforms the same day.

Are trending audio tracks supported?

AdLit doesn't license trending TikTok or Reels audio (those live in each platform's native library for licensing reasons). Export the video clean from AdLit and add the trending track inside TikTok or Reels — that's the same workflow human creators use.

Short-form vertical video — Reels, Shorts, TikTok — runs on different rules than every other format. Hook in 1.5 seconds. 9:16 vertical only. Captions baked in. Loop-ready endings. AdLit's Shorts pipeline renders all three platforms from a single source: same script, same actor, exported with the right safe zones, right caption styling, and right pacing per platform.

The reality

Why this is hard today

Cross-posting is broken

Posting the same video to Reels, Shorts and TikTok in one click feels great until you notice the captions are cut off, the safe zone is wrong, and the engagement tanks because each platform's UI overlays different chunks of the frame.

Platform style differences

What works on TikTok (fast cuts, low-fi, trend-driven) doesn't always work on YouTube Shorts (educational, longer dwell). Rendering once per platform means matching each platform's content conventions, not just the aspect ratio.

Volume requirement is brutal

Algorithms favor accounts that post daily. Most brands can't film a fresh creator-style short every day. AI shorts close that gap without losing the creator-style aesthetic.

What you can ship

Built for these workflows

One idea, three platforms

Same script, exported as a TikTok variant (fast cuts), Reels variant (Instagram safe zone), and Shorts variant (YouTube caption position). Hit all three feeds in one production session.

Daily posting cadence

Generate a week's worth of shorts in one Monday sitting — 7 hooks × 3 platforms = 21 assets. Schedule via your social tool of choice and free your social manager to focus on engagement.

Long-form repurposing

Take a 5-minute talking-actor explainer and chop it into 10 shorts, each with a different hook overlay. One production effort, ten distribution opportunities.
