Start with Ready-made Formats for product video: the Sume Format catalog
Instagram carousel limit of 10: make 10 stills from one video
Meta's guide limits carousels to 10 images, videos or a mix, and 100 API posts per 24 hours. Sume video-frames takes up to 24 times per call, so pick 10.
Instagram carousel crops to the first image: crop stills to match
Meta says carousel images are cropped based on the first image, default 1:1. Sume video-filter crop, then video-frames, gives stills that share one shape.

Meta lists Reels at 3 seconds minimum, but Sume video-trim accepts down to 0.2 s. Read duration_seconds from the trim result before you publish.
LinkedIn Videos API: 500MB or 5GB? Plan for the lower number
LinkedIn's Videos API page lists a 75kb to 500MB file size and a 5GB maximum. Sume states no output file size, so measure the MP4 first.
LinkedIn Videos API thumbnail: pick a still from the clip first
LinkedIn's Videos API page says a system thumbnail may be added if you upload none. Sume video-frames returns jpeg stills at times you choose.
LinkedIn video captions: English SRT only vs burned-in text
LinkedIn's Videos API takes one English caption file, shown with SRT. Sume video-captions burns your cues text into the video and does not accept SRT uploads.

CAP says a realistic AI celebrity endorsement can breach the Code and the advertiser stays responsible. Which Sume avatar inputs involve a real person's photo.

Demand Gen video crop and trim tool vs an API crop and trim
Demand Gen's console tool crops to 16:9, 1:1 or 9:16 and trims 5 to 300 seconds. The same edit as two Sume calls: a video-filter crop, then video-trim.
Descript captions: in/out animations vs Sume design overrides
Descript captions now have separate in and out motion. Sume's video-captions API exposes enter, exit and emphasis timing through a design object.

The Commission's icons page gives a face swap in an authentic photo as its Partially AI-Modified example. What that means for a Sume face-swapped video.
FLUX Deblur: 4 MP input vs Sume's 1-4x image upscale

Google Merchant Center video_link needs a video of 6 to 240 seconds. Probe the length, then cut a longer clip to size with Sume Video trim into a new MP4.

Merchant Center video_link needs at least 720p (1280x720). Sume's generated video defaults to 720p; probe a file first, then conform with Video trim if needed.
Merchant Center video link aspect ratio: 9:16, 16:9, 1:1
