Does this upscaler preserve the original audio track?
Yes! The audio stream is copied and accurately re-synced with AAC encoding to ensure zero audio drift or quality degradation.
AI Video Upscaler
Enhance low-resolution video clips with neural frame reconstruction.
Standard video scaling tools simply stretch pixels across frames, creating muddy visuals, blocky compression artifacts, and noticeable temporal flicker. True video upscaling requires an intelligent engine that understands motion across sequential frames.
UltraScale AI Video Upscaler leverages multi-frame temporal analysis. By evaluating contiguous video frames simultaneously, the system reconstructs edge data, reduces high-ISO noise, and produces crisp lines that remain rock-solid from frame to frame.
Perfect for creators upgrading legacy 720p or 480p footage for YouTube, TikTok, Instagram Reels, or 4K monitors.

Answers & Details
Frequently Asked Questions
Why does video upscaling take longer than photo upscaling?
A 10-second video at 30 frames per second contains 300 individual frames. The model processes each frame while calculating inter-frame motion vectors.
What is the maximum file size supported?
You can upload video files up to 100MB per job directly in your browser.
