Article URL to video AI: turn a blog post link into a video
An article URL to video tool makes a short video from a post. On Sume send the article text in input and its images as attachments; the link alone is not read.
An article URL to video tool takes the link to a post, reads its headline, text and images, writes a script and returns a short video. On Sume, send the article's text in input (caller data, for example { article: ... }) and its images as attachments to an Agent Completion; the docs describe no step where Sume opens the link and reads it for you.
Sume's limits are from Create a run and the Format API docs, read 2026-09-29. Neither page describes Sume fetching an article link for you.
What do I send instead of the link?
| From the article | Field | Limit |
|---|---|---|
| Headline and body text | input | 2 MiB |
| Article images | attachments as input_image | 30 images, 30 MB each |
| The page address | A URL inside input | Not a media file, so not counted against the media budget |
| Length, tone, format | instruction | About 4,000 characters reach the prompt |
How do I run it from a feed?
Fetch each new article on your side, extract the text, and make one call per article with an Idempotency-Key built from the article's id, so a re-run does not bill a second video. Blog to video AI walks through the loop.
What should the video say?
Say in the instruction to use only facts from the supplied text, and to show quotes and numbers exactly. Then read the draft against the article before you post it: a summary can drop a caveat the article had.
Can I reuse the article's images?
Only if you have the right to. Attach images you own or are licensed to republish, and leave out the rest; the agent can generate visuals instead.
