Enhance Video Quality Like a Studio
Don't settle for blurry, pixelated footage. Our AI Video Upscaler uses deep learning algorithms to analyze every frame, intelligently predicting and generating missing pixels to increase video resolution.
-
1
4K Super Resolution
Convert standard definition (SD) or 1080p footage into stunning 4K UHD. The AI retains textures without artificial smoothing.
-
2
Video Noise Reduction
Automatically remove grain and compression artifacts common in low-light recordings or old VHS digital transfers.
-
3
Frame Rate Boost (App)
Use our pro app to not only upscale resolution but also interpolate frames, converting 30FPS footage into buttery smooth 60FPS.
Revive Your Old Footage
Perfect for restoring old home videos, upscaling low-res anime clips, or preparing content for high-definition YouTube uploads.
When AI Video Upscaling Saves the Day
Archival
VHS & Home Video Restoration
Digitized VHS tapes, Super 8 film scans, and DVD rips come with severe resolution limitations and heavy compression artifacts. Our AI upscaler removes tracking lines, macro-blocking, and grain while converting footage to a clean HD or 4K master.
Action & Drone
Drone & Action Camera Footage Enhancement
Even 4K drone footage can look soft and noisy when shot in difficult lighting or with a compressed bitrate. AI super-resolution sharpens fine details like tree lines and architectural features — making every aerial shot look broadcast-ready.
Content Creation
Social Media Reels & Short-Form Content
Repurposing old footage for Instagram Reels, TikTok, or YouTube Shorts means competing with natively shot 4K content. Our AI upscaler brings legacy clips to modern quality standards so older content performs just as well as new material.

Need to Enhance Photos Instead?
Our video upscaler is powerful, but if you have a blurry still image that needs fixing, our dedicated Image Unblur AI is optimized specifically for still photography and portraits.

Simply upload your video to Hividai. Traditional software uses basic interpolation that stretches pixels, causing blur. Our AI Video Upscaler uses deep learning to generate brand new pixels based on surrounding visual data, effectively converting 720p or 1080p footage into true, crisp 4K resolution.
Yes, you can test our AI video enhancement capabilities online for free using the web preview. Because video processing requires massive server GPU power, for full 4K 60FPS rendering and unlimited batch processing, we recommend downloading our dedicated mobile app.
Absolutely. The AI model is specifically trained to recognize compression artifacts, VHS tracking lines, and film grain in old videos. It actively removes this noise while upscaling the resolution, giving vintage footage a clean, modern look.
Yes. Increasing the resolution from 1080p to 4K means you have four times the amount of pixel data per frame, which naturally results in a larger file size. However, we use efficient modern encoding formats to keep the file size as optimized as possible without losing quality.
Our AI video upscaler accepts the most widely-used modern formats including MP4 (H.264/H.265), MOV (ProRes/HEVC), and MKV (H.264). Output is encoded in optimized H.265/HEVC for maximum quality at the smallest possible file size, ensuring your enhanced 4K video is practical to store and share.
Yes. MPEG compression artifacts such as blocky macro-blocking, color banding, and mosquito noise are specifically targeted by our enhancement model. The AI was trained on thousands of examples of heavily compressed social media and streaming video, so it knows exactly how to reconstruct a clean, original-looking frame from a corrupted or over-compressed input.
Yes, our AI is highly effective for anime upscaling. Anime content has distinct visual properties — clean line art, flat color regions, and sharp outlines — that our model preserves without the blurry watercolor effect generic upscalers produce. Whether you want to upscale anime clips from 480p or 720p to crisp 1080p or 4K, every line stays sharp and every color stays accurate. It also works great for animated movies, cartoons, and motion graphics.
