Start with Ready-made Formats for product video: the Sume Format catalog
X video ads loop under 60 seconds: design the last frame of a 45 s ad
X loops video ads shorter than 60 seconds and plays longer ones once. Plan the first and last second differently for each, then check them with Sume.
X standalone video lists 16:9 and 1:1: set the Sume render size
Sume timeline renders 1080x1920 by default, but X's standalone video ad spec lists 16:9 and 1:1. Set output width and height to 1920x1080 or 1200x1200.
Does a lip-synced dub in your own voice need YouTube's AI label?
YouTube says cloning your own voice for voice-overs or dubs needs no disclosure; a real person made to say what they never said does. How Sume lip sync fits.
X video ad under 30 MB: how many seconds fit at 6,000 and 5,000 kbps
X says keep video ads under 30 MB. At its 6,000 kbps (1080p) and 5,000 kbps (720p) targets that is 40 and 48 seconds. Check yours with Sume video inspect.
TikTok AI disclaimer sits at the bottom: keep burned captions higher
TikTok's ad disclaimer shows at the bottom of in-feed video for the whole ad. Place Sume burned-in captions higher with placement.anchor_ratio and test.
LinkedIn landscape video ad maxes at 1920x1080; Sume allows up to 2160
LinkedIn's landscape video range is 640x360 to 1920x1080, but Sume timeline accepts sizes to 2160. Pick 1920x1080 on purpose and verify with video inspect.

Photo avatar of a real person: when YouTube's AI label applies
A photo avatar scripted to say new words falls under YouTube's 'real person says something they did not' test. How Sume's three avatar inputs map to it.
X video ad: 2:20 at 6,000 kbps is 105 MB, so the 1 GB cap never binds
X allows 1 GB and 2 minutes 20 seconds. At its recommended bitrate the length limit hits first. The math, plus the 9:55 case for approved advertisers.
Real footage trimmed and captioned on Sume: TikTok AI disclaimer?
