One ad for X and Snapchat: no shared aspect ratio, render two masters

X and Snapchat share no video aspect ratio: X lists 16:9 or 1:1 for video ads and Snapchat lists 9:16. They do share a length, because X supports up to 2:20 (140 seconds) and Snapchat accepts up to 180 seconds. So build two renders from the same cut, each at most 140 seconds, and a Sume timeline render for each costs 3 x $0.10 = $0.30.

What each platform lists

Both rows come from the platforms' own pages.

Render both on Sume

Timeline 1.0 outputs one size per render, so you need a render per ratio. Use width and height of 1280 and 720 (or 800 and 800 for square) for X, and 720 and 1280 for Snapchat. Each size is within the allowed even 256 to 2160 range (Sume docs, read 2026-10-08).

For the Snapchat render of a wide source, choose fit blur or cover on each slot, as described in the fit-mode post linked below. For the X render of a vertical source, the same applies in the other direction.

Cost of two masters at 140 seconds, computed 2026-10-09, as listed below.

• X, 1280x720: working ceil(140 / 60) = 3 min x $0.10; cost $0.30
• Snapchat, 720x1280: working ceil(140 / 60) = 3 min x $0.10; cost $0.30
• Both: working $0.30 + $0.30; cost $0.60

Why 140 seconds and not 180

The shorter cap decides. X's page says up to 2:20 is supported, so a 150-second Snapchat cut would be rejected by X even though Snapchat allows it. A 140-second timeline still bills as 3 minutes because the render is rounded up, so the same price covers anything from 121 to 180 seconds. Trim to 120 seconds or less to drop to 2 minutes and $0.20 per render.

• If the Snapchat ad is a Commercial, only the first 6 seconds are non-skippable.
• If the X ad is short, X recommends 15 seconds or less.

Keeping the two versions consistent

Make the cut once, then reshape it. Edit the story on a single timeline document, and for each output change only the output size and the fit mode of each slot. That keeps the timing, the voice and the soundtrack identical in both files, so any performance difference comes from the shape, not the content.

Run the unbilled plan endpoint on each document before you render. It checks the document compiles and reports the billable minutes, so you see the $0.30 before any credits move.

If you also run the ad on other networks, the same approach scales. Each extra aspect ratio is one more render at the same minute rounding, so the cost grows by $0.30 per 121 to 180 second master, or $0.20 per master at 120 seconds or less. Decide the set of ratios before you cut, because adding a ratio later means re-checking every text position.

Neither page in this comparison lists a safe zone for these video formats, so place text away from the edges and check it on a still from each render.
