Video Upscaler API

About Video Upscaler

Upscale a 3–60 second clip to 720p, 1080p, 2K or 4K. Length, motion and the audio track are kept; the picture comes back larger and cleaner.

Call it with the model name popnow/video-upscaler-v1/upscale on POST /jobs/createTask, from 0.9 credits per second ($0.009). New accounts get 30 free credits to try it in the Playground first.

Introduction

Video Upscaler takes a finished clip and returns it at a higher resolution tier. It is a resolution pass, not an editor: framing, motion, cuts, timing and the original audio track all stay as sent. There is no prompt.

Request

{
  "video_url": "https://example.com/clip.mp4",
  "resolution": "1080p"
}

Only video_url is required. resolution defaults to 1080p; the other tiers are 720p, 2k and 4k.

What comes back

The tier is a pixel budget and the aspect ratio is kept. An 832×480 clip came back at 1896×1094 at 1080p after about 33 seconds of processing, and at 3792×2188 at 4k after about 103 seconds; a 5-second 4k MP4 is around 19 MB. An 854×480 clip with an AAC soundtrack came back at 1922×1080 with the same track. In every test the running length matched the source to the frame.

Task flow

The call is asynchronous.

Tips

• Upscale the final cut, after every edit.
• Pick a tier above the clip's current resolution.
• Use a direct link to the video file.
• Start from the cleanest source you have: compression blocks and noise are enlarged too.

Request parameters

Pricing

Prices are in credits, the same credits you use on the website (1 credit = $0.01). The hold is taken when the task is accepted and settled to the actual charge when it finishes; failed tasks are refunded.

For an exact number before you run, send the same body to POST /jobs/quote.

API quick start

Call the Video Upscaler 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- and use the same credits as the website.
2. Send the request. POST /jobs/createTask with model popnow/video-upscaler-v1/upscale 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": "popnow/video-upscaler-v1/upscale",
  "input": {
    "video_url": "https://media.popnow.ai/effects/flower-bloom-1abd6efb.mp4",
    "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.
