# AI Video Quality Enhancer

> An online AI video enhancer that denoises, sharpens, restores color, removes compression artifacts, and upscales footage with super-resolution to 1080p, 2K, or 4K. Every new account gets free credits on sign-up; after that, usage is billed per second of output video. Live at https://videoqualityenhancer.org.

## What it does

- **Enhance & restore**: temporal AI models look at neighboring frames to separate real detail from noise, then rebuild edges and textures — removing sensor noise, motion blur, low-light grain, and repeated-compression artifacts (block artifacts, color banding).
- **Upscale**: super-resolution to a target resolution of 720p, 1080p, 2K, or 4K, and a target frame rate of 30 or 60fps. It rebuilds real detail instead of stretching pixels. Input is accepted up to 2K.
- **Two enhancement modes**:
  - **Standard** (from 1 credit/sec) — fast, balanced enhancement with 10+ algorithms and scene presets, for everyday clips.
  - **Deep AI Algorithms / Professional** (Standard rate ×10) — cinema-grade quality with 30+ AI algorithms, for film-level 4K production.
- **Scene presets**: General (fixes compression blur/artifacts), AIGC (upscales & repaints AI-generated videos), Short drama (portrait/detail enhancement), and Old film restoration (scratch removal, deflicker, color-cast correction for degraded historical footage).
- **Compare & download**: a before/after slider previews the result before downloading the enhanced MP4.

## How it works

1. Upload a clip (drag & drop). Duration and resolution are read automatically.
2. Choose the enhancement mode, scene preset, target resolution, and frame rate.
3. The AI processes every frame in the background — no need to keep the page open.
4. Compare the before/after slider and download the enhanced MP4.

## Key facts

- **Supported input formats**: MP4, MOV, MKV, AVI, FLV. Input resolution up to 2K; file uploads up to 1GB.
- **Processing time** (rough guide): Standard ≈ 6 min per 1 min of video; Deep AI Algorithms ≈ 20 min per 1 min.
- **Billing**: per second of output duration (rounded up); 1 credit/sec = 60 credits/min. The credits/sec rate scales with output resolution and frame rate. Deep AI Algorithms = Standard × 10.
- **Plans**: free credits on sign-up, then either one-time credit packs (valid 1 year from purchase) or a monthly subscription (credits reset each billing period; unused credits do not roll over). Tiers: Starter, Pro, Ultimate.
- **Privacy**: uploaded and result files are stored for 30 days, then auto-deleted. Videos are never used for training.
