Resolve 21.1 batch render with AI assistants vs Formats bulk runs

Blackmagic says DaVinci Resolve 21.1 integrates with AI assistants such as Claude, Claude Code and ChatGPT Codex to analyze projects, organize media, adjust settings and batch render. That is automation of your own Resolve project on your own machine. Sume's equivalent for hosted work is Formats bulk runs: one POST /v1/formats/{handle}/{slug}/bulk-runs queues 1 to 100 items, with a concurrency of 1 to 16.

How a bulk run behaves

The create call returns 202 and a queue receipt, which you poll at GET /v1/format-run-queues/{id}. There is no queue-level webhook, so polling is how you know it finished. A queue status of completed does not mean every item succeeded: read each item. The first-party catalog includes formats such as sume-slideshow, sume-recreate and sume-restyle; the catalog page lists what is available to you.

Choosing

Use Resolve automation when the source is a project with grades and fixed settings. Use bulk runs when the inputs are a list of URLs or prompts and the output is a repeatable Format. They can be combined: render masters in Resolve, upload them, then run a Format over the set.

Honest limits

• Queue size is capped at 100; larger sets need several queues.
• No queue webhook exists, so build polling with a sensible interval.
• Blackmagic's press release names the assistants but gives no limits, so none are compared.
