Canva design generation job v2 vs a Sume timeline plan for a brief
Canva's Sep 29 preview creates a design or presentation from a text brief. Sume's timeline plan checks a clip video for free but writes no brief.
What each does
Per the Canva Connect changelog, the design generation job v2 (preview, September 29) creates a design or a presentation from a text brief. It generates the content. Sume's Timeline 1.0 does not: it assembles clips you already have and one audio track into a single MP4, and its plan call is an unbilled preflight.
Side by side
| Item | Canva design generation v2 | Sume Timeline 1.0 |
|---|---|---|
| Input | Text brief | audio spine plus video[] slots |
| Output | A design or presentation | One MP4 |
| Status | Preview | Public API |
| Creative writing | Yes, from the brief | No, clips come from other jobs |
| Cost check | Not read | plan returns estimated_cost_usd_micros, no billing |
Use them in order
A sane pairing: let Canva draft the visual structure from the brief, make the moving clips on Sume, and assemble them with a timeline render. Before you pay for the render, call POST /v1/timeline-1.0/plan to get the duration, segment count and estimated cost. A plan does not download media or reserve funds.
Remember the limits: Timeline accepts 1 to 1,800 seconds of audio and 1 to 200 video slots, and every URL must be this workspace's media.sume.com artifact.
Caveat
Canva's changelog gives no limits or fields for the job in my read, and preview APIs can change. Check Canva's reference before coding against it. On the Sume side, see Timeline 1.0 for the exact fields.
