Topaz Video AI API

About Topaz Video AI

Upscale to 4K, remove noise or blur, convert to HDR, smooth or slow down motion.

Call it with the model name topaz/video-ai/video-edit on POST /jobs/createTask, from $0.004.

Introduction

It suits night interiors, a soft performance take and SDR footage entering an HDR edit. Each request selects a single operation, which makes its visual effect easier to assess.

Key features

Four Nyx variants handle different noise demands: natural texture, faster batch work, very heavy noise and finer treatment. The cellar test reduced conspicuous grain while leaving groups of hair discernible; the wood behind the subjects also became smoother. This is a balance between cleanup and the small texture that makes a surface convincing.

The remaining choices are deblur and three Hyperion versions. Deblur produced a restrained improvement on the dancer, whose face still looked soft. Hyperion returns ten-bit HEVC instead of the H.264 used by other treatments. The inspected 2.5 sample carries PQ metadata, whereas the inspected Hyperion 1 sample carries HLG metadata, so verify the actual file rather than assuming one transfer curve.

Request parameters

Pricing

Prices are in USD. The API uses a separate USD balance. Website credits cannot be used or transferred to it, and API funds cannot be transferred to website credits. When a task is accepted, we reserve the maximum quoted amount from your API balance. On completion, we charge for actual usage, never more than the hold, and release the remainder. If the task fails, the hold is released.

Send the same request body to POST /jobs/quote to see the estimated and maximum USD charge before running. A quote does not run the task or charge your balance.

Use cases

For a low-light conversation, inspect shadow noise and the face together before accepting a cleanup pass. A quiet background is useful only if the person still looks suitable alongside the other shots in the sequence.

For an HDR master, create a Hyperion version of the selected SDR take and review it inside the intended HDR workflow. A browser that cannot play the file is insufficient evidence about its brightness or color rendering.

Prompt guide & pro tips

This endpoint takes presets rather than written prompts. Identify the dominant problem first: noisy shadows suggest Nyx, softness suggests deblur, and a delivery requirement may call for Hyperion. Select one representative passage containing both difficult texture and a human subject, then hold the resolution steady while assessing the treatment.

After downloading, compare the same moments at equal display size and replay motion around hair, hands and bright edges. Inspect codec, bit depth and HDR metadata when converting dynamic range, and judge the result on compatible equipment.

API quick start

Call the Topaz Video AI API in three steps

1. Create an API key. Sign in to PopNow and create a key in the API console. Keys start with sk-popnow-. API calls use your separate USD balance.
2. Send the request. POST /jobs/createTask with model topaz/video-ai/video-edit and an input object that follows the parameter table. The response returns a task ID straight away.
3. Get the result. Poll GET /jobs/recordInfo with the task ID, or pass a callBackUrl and we post the result to it. Download the output links when the task succeeds.

# 1. Create the task. Keep the Idempotency-Key if you retry after a network error.
export IDEMPOTENCY_KEY="$(uuidgen)"
curl -X POST https://api.popnow.ai/api/v1/jobs/createTask \
  -H "Authorization: Bearer $POPNOW_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $IDEMPOTENCY_KEY" \
  -d '{
  "model": "topaz/video-ai/video-edit",
  "input": {
    "video_url": "https://media.popnow.ai/effects/flower-bloom-1abd6efb.mp4",
    "preset": "nyx",
    "resolution": "1080p"
  }
}'

# 2. Copy data.taskId from the response, then poll until state is succeeded, failed, canceled or expired.
TASK_ID="TASK_ID_FROM_RESPONSE"
curl "https://api.popnow.ai/api/v1/jobs/recordInfo?taskId=$TASK_ID" \
  -H "Authorization: Bearer $POPNOW_API_KEY"

Replace the prompt and any links with your own. The API tab has the response, polling and callback reference.
