flashvsrFlashVSR takes a low-resolution clip and returns a sharper one at 720p, 1080p, 2K or 4K — restoring old footage, cleaning up low-bitrate video, and lifting AI-generated clips to a resolution you can actually cut with. Billing is per second of the SOURCE video, not the output, so the cost is fixed the moment you submit: a 30-second clip to 1080p is $0.90, every time. Send a publicly reachable MP4 URL up to 120 seconds and poll for the result. Against Topaz — the usual alternative — the difference is both price and structure: Topaz's official plan is a monthly subscription whose credits expire at the end of each month, and once you exceed the quota add-on credits cost $0.10 each, about $0.067 per second of HD. FlashVSR is pay-per-use at $0.03/s for 1080p, with nothing to commit to and nothing that expires.
Upload the source clip (MP4, max 100MB here, up to 120s; the API takes up to 500MB by public URL). Billed per second of this clip, not of the result.

The bill is fixed by the clip you send, so you can quote a job before you run it. A 30-second source to 1080p costs $0.90 whether the render takes one minute or five.
Topaz's official pricing is a monthly plan; past its quota, add-on credits are $0.10 each — roughly $0.067 per second of HD. FlashVSR is $0.03/s at 1080p, $0.02/s at 720p, with no monthly fee underneath it.
Topaz video credits reset at the end of every month and do not roll over, so an unused month is money gone. Here you pay for the seconds you actually process.
720p, 1080p, 2K and 4K. Pick the tier you need rather than a fixed multiplier — useful when the source resolution varies across a batch.
Async create-then-poll with a task id, so a long queue of clips can be submitted and collected without holding connections open. Failed tasks are never billed.
MP4 by public URL only (no base64), 500 MB and 120 seconds per clip. We check the duration before submitting and reject over-long or unreachable clips immediately, instead of failing minutes later upstream.
FlashVSR Video Upscale is a Video Generation API provided by FlashVSR.

The **source** clip. That is the opposite of most per-second video models here, and it works in your favour: the price is fixed the moment you submit, regardless of how long the render takes. A 30-second source to 1080p is $0.90 every time, so you can quote a job before you run it. Rates per source second: 720p $0.02, 1080p $0.03, 2K $0.035, 4K $0.06. Upscaling does not change duration — the output is as long as the input.
On the rate, and on the billing structure. Topaz's official offer is a monthly subscription: Astra Standard is $19/mo for 400 credits, which their own page describes as roughly 10 minutes of HD video — about 0.667 credits per second. **Those credits expire at the end of each month and do not roll over**, so an under-used month is money gone. Past the quota, add-on credits are $0.10 each, which works out to about **$0.067 per second** of HD. FlashVSR is pay-per-use with no monthly fee and nothing expiring: 720p $0.02/s (70% less), 1080p $0.03/s (**55% less**), 2K $0.035/s (48% less), 4K $0.06/s (10% less). If your volume is steady enough to exhaust a Topaz plan every month, the marginal rates get closer. The moment volume varies, the expiring credits are a straight loss — and that failure mode does not exist here.
120 seconds and 500 MB per clip, MP4, and **public URLs only — base64 video is not accepted**. We check these before submitting: a clip whose duration cannot be read, or one over 120 seconds, gets an actionable error immediately rather than a failure minutes later upstream. Signed-expiry links, anything behind a login, and private addresses are rejected for the same reason — if we cannot fetch it, neither can the upstream. One more thing worth knowing: asking for a tier at or below the source resolution (720p output from a clip that is already 720p) re-encodes without genuinely enlarging anything, so check the source resolution before picking a tier.
Three common cases: **restoring old footage** (low-resolution archives, transfers), **rescuing low-bitrate sources** (heavily compressed clips with visible noise and blocking), and **lifting AI-generated video to an editable resolution** — many video models top out at 480p or 720p, which looks soft on a 1080p timeline until it has been through an upscale. The API is async: submit, get a task id, poll for the result. Suits batch work. Failed tasks are never billed.
