Upscale a Vidu Q4 clip on Sume: $0.009 per input second, 30 s max

Yes. Sume does not list Vidu Q4 as a generator, but the video upscale route takes any public HTTPS video_url and bills $0.009 per input second, so a clip you made at Vidu can be upscaled on Sume for $0.045 per 5 seconds. The route accepts up to 30 input seconds per job.

Vidu announced Q4 Preview on October 7, with launch pricing that starts at $0.014 per second and output from 540p to 4K, according to its press release on PR Newswire (read 2026-10-10). That release is the only Vidu source used here.

What Sume lists instead

The Sume video router lists eleven models: seedance-2.5, seedance-2-mini, seedance-2, seedance-2-fast, kling-3, wan-3.0, grok-imagine-video-1.5, minimax-h3, minimax-h3-max, gemini-omni-flash-1.1 and h3-max-recast. Vidu is not among them, so a Vidu clip is something you bring in, not something you submit through Sume.

Bringing it in is simple for upscaling. The request needs video_url as a public HTTPS URL; localhost, private-network and non-HTTPS URLs are rejected. The other media tools, such as trim and filter, are different: they require a media.sume.com clip from your workspace, so they do not accept the Vidu URL directly.

The request fields that matter

scale_ratio runs from 1.1 to 4 with a default of 2, and upscale_factor is an alias that scale_ratio overrides when both are set. enhancement_tier is fast, standard or pro, with fast as the default. duration_seconds, from 1 to 30, is the input length used for the reservation.

Leave duration_seconds out and Sume reserves 5 seconds. For a 12-second clip that understates the cost, so send the real length. The reservation maximum is 30 seconds per job, so split a longer clip into parts of 30 seconds or less before you host them, as in the 45-second split example. Each part is its own job, so 45 seconds becomes two jobs.

What a job costs

The Vidu column uses the lowest launch price in the release, so it is a floor and not a quote for any tier or resolution. Check Vidu's own page for the price of the tier you use. The Sume column is the public rate multiplied by the seconds; confirm the live rate in GET /v1/catalog.

When upscaling is the wrong tool

Vidu says Q4 reaches 4K. If you already render at 4K, a scale of 2 is rarely needed. A lower-resolution draft is the natural input. Pick the scale from what the destination platform needs, and keep the file under the host limits of that platform. A 540p clip scaled by 2 lands near 1080p; a scale of 4 would be an extreme stretch for any source.

Also keep expectations on the output: an upscaler adds pixels, not new content, and this page makes no claim about a quality score or a benchmark. Run one 5-second test first, which costs $0.045, and compare it with your target before you queue a batch. If you plan 200 five-second clips, the Sume step alone is 200 x $0.045 = $9.00, and the floor price of the same 200 clips at Vidu is 200 x $0.070 = $14.00, so the combined floor is $23.00. Both figures change if you choose a higher tier or resolution.

Submit pattern

Send the job with an Idempotency-Key, mode async by default, then poll GET /v1/jobs/:id/status until it is complete and read GET /v1/jobs/:id/result. Sync mode waits at most 30 seconds for a result and otherwise returns 202. The route fetches the URL you give it and never changes the original file, so the Vidu copy stays as it was. Keep your own copy of the result, because job results are tied to your workspace.
