Does Sparki just crop my video to a new aspect ratio?

No. Sparki reframes around the subject, moves captions out of each platform's UI safe zones and adjusts the cut length so the edit fits how that feed is actually watched.

Can I export several aspect ratios from one edit?

Yes. Build the edit once and export 9:16, 1:1 and 16:9 masters together, so a single shoot covers short-form feeds, paid ads and your product page.

How long should a video be on each platform?

Short-form feeds reward 15 to 60 seconds, paid social performs best between 6 and 30 seconds, marketplace listing videos sit around 30 to 60 seconds, and YouTube tutorials can run several minutes when the structure is clear.

Are captions added automatically for every platform?

Yes. Sparki transcribes the audio and burns in captions styled for each placement, keeping them inside the safe area so platform buttons never cover the text.

Can I publish directly from Sparki?

Sparki exports finished files ready for upload to each platform, so you keep control of scheduling, descriptions and hashtags in whichever tool you already use.

Every Platform, One Edit

Paste an X, Instagram, TikTok or Facebook link — or upload a file for any other platform — and Sparki reframes, re-paces and captions the same footage into a master built for that feed, storefront or ad placement.

Why Export Per Platform

The same footage performs differently in every feed. Sparki re-cuts and re-frames instead of just cropping.

Native Framing, Not Crops

Each export is reframed around the subject and keeps captions clear of the platform UI overlays.

Pacing Per Placement

A 6-second ad and a 60-second tutorial need different cut rhythms. Sparki adjusts length and density per target.

One Edit, Every Ratio

Build the cut once and export 9:16, 1:1 and 16:9 masters together so a single shoot covers every channel.
