Frequently Asked Questions
We have answers to the most common questions that our users ask.
Is the Denoise Video tool free?
Anyone can try Kapwing’s AI Toolkit for free without watermarks, but our AI tools run on a credit system, with each feature costing a set number of credits. For maximum creativity and the best value, upgrade to a Pro account to unlock the full power of AI-driven content creation.
What is AI denoising?
AI denoising video tools remove unwanted visual noise like grain, compression artifacts, and low-light speckling while preserving edges and detail. Instead of blurring the entire frame, Kapwing’s AI video denoiser selectively cleans noisy areas so your footage still looks sharp and natural.
This makes denoise AI especially effective for grainy video shot on phones, webcams, or inexpensive cameras.
How do I fix a grainy video with Kapwing?
To fix a grainy video, upload your clip to Kapwing and use a simple prompt like Denoise this video. The AI analyzes each frame to clean up grainy video artifacts, reduce blur, and smooth visual noise automatically.
You can further clean up grainy video by combining denoise for video with other video enhancing tools like Upscale Video, color adjustments, and compression fixes, all in one workflow.
What types of videos work best with an AI video denoiser?
AI video denoisers like Kapwing work best on footage with visible grain, low-light noise, or compression artifacts. This includes social media clips, screen recordings, old footage, livestream replays, and videos shot on mobile phones.
Kapwing is especially useful for denoising video that’s already been compressed or repurposed, helping restore clarity without re-shooting.
Can I denoise video in real time on my mobile phone?
Kapwing doesn’t currently support real time video denoising on mobile phones, but you can upload mobile footage from any device and denoise it online in just a few clicks. The processing happens in the cloud, so there’s no performance hit on your phone.
This approach delivers higher-quality results than real-time filters while keeping your workflow fast and flexible.
Will denoising reduce video quality or detail?
No, Kapwing’s denoise AI is designed to reduce noise without flattening textures or softening edges. The model focuses on removing unwanted artifacts while preserving high-frequency detail, motion, and facial features.
If you want even more clarity, you can pair denoising video with AI resolution upscaling for a sharper final export.
What video file types does Kapwing support?
Kapwing works with all major video file types, including MP4, MOV, and WebM. Your denoised video will be immediately downloadable as an MP4, but you can move it to the studio to export as your preferred file type and adjust resolution and compression.
