NSFW AI Video Enhancer upscale adult clips to 4K

Quick answer

Kenerate's AI video enhancer is its video upscaler, built on LTX-2 19B: upload a clip of up to 5 minutes and 200 MB and choose 720p, 1080p, 2K or 4K. It sharpens detail and texture at the new size; it doesn't change the frame rate or add frame interpolation. The tool runs on credits, including the 25 free sign-up credits (enough for a few seconds of test). For a new adult clip, rendering at a higher resolution in the first place is often better: Seedance 2.5 Spicy outputs up to 4K and Wan 3 Spicy up to 1080p.

Short answers

What people ask first

  • Can I upscale an NSFW video with AI?

    Kenerate's video upscaler takes clips up to 5 minutes and 200 MB and outputs 720p, 1080p, 2K or 4K. It's a general tool with no separate adult mode.

  • Does it add 60 fps or frame interpolation?

    No. The upscaler keeps the clip's frame rate; Kenerate has no frame-interpolation tool.

  • Is it free?

    It runs on credits, and the 25 free sign-up credits work on it — enough for a short test. Spicy video generation needs a credit pack.

  • Upscale or re-render?

    For a clip you already have, upscale. For a new clip, render at a higher resolution to begin with — up to 4K on Seedance 2.5 Spicy.

Tips

Getting the most from an upscale

What made a visible difference in our tests.

  • Start from the cleanest source you have — upscaling can't fix heavy blur.
  • Go one or two steps up (720p → 1080p or 2K) before jumping to 4K.
  • Upscale the final cut, not every draft.
  • For new clips, render at a higher resolution on Seedance 2.5 Spicy instead.
  • Frame rate stays the same — there's no interpolation.
  • Only clips of fictional adults or yourself.

Rules and privacy

Adult video for adults 18+, with one rule that never changes.

  • 18+ and fictional adults only

    Adult prompts are for adults. Every character you create must be a fictional adult.

  • Blocked and not allowed

    Kenerate's prompt filter blocks prompts involving minors on every model, and it can't be switched off. Sexual images of real people aren't allowed.

  • Blurred by default

    Results flagged as adult are shown blurred in your gallery grid.

  • Private switch

    Turn on Private in Advanced settings to keep a generation out of the public feed.

Make the start image first — then animate it with the model that fits the shot.

In depth

NSFW AI Video Enhancer, explained

What the models can do, how to prompt them, and what isn't allowed.

What an AI upscaler actually does

It predicts the detail a sharper camera would have caught — skin texture, fabric, hair — and renders the clip at the new size. It works best on clean, slightly soft footage; heavy blur, blocky compression or very dark frames limit what it can recover.

Frame rate and motion

Upscaling changes resolution, not motion. Pages that promise '60 fps enhancement' are describing frame interpolation, which Kenerate doesn't offer; smooth motion comes from the video model itself.
