AI Video Blur

You can blur anything you can describe with a prompt — for example faces, people in the background, license plates, screens, or specific objects.

You can also choose to blur the background (keep subject sharp) or blur the subject/foreground (keep background sharp).

Write what you want blurred (your prompt), upload your video, and the tool processes the entire clip using that instruction.

Tip: Clear prompts work best, like:

• "blur all faces"
• "blur license plates"
• "blur everyone except the main speaker"

Yes — the AI supports multiple objects in the same video.

If a scene contains many objects at once (e.g., big crowds), results can be less stable and processing may take longer.

In crowded scenes (many faces/objects), detection and tracking can be harder. For best results, try:

• A more specific prompt (e.g., "blur only background people")
• Using a higher blur intensity
• Splitting the video into smaller clips

We currently support Gaussian blur and Box blur.

Gaussian blur gives a smooth, natural-looking effect. Box blur is faster but slightly less smooth.

Yes — you can adjust the blur intensity from 0 to 100 to get stronger or lighter anonymization. The slider is available in the editor before processing.

You get an automatic preview for background blur mode.

For prompt-based blur on specific objects, the exported video is the final result (no frame-by-frame preview refinement yet).

Not yet — currently the blur is applied to the whole video.

Workaround: You can trim your video before uploading to blur only the section you need.

Input formats: MP4, MOV, WEBM

Output format: MP4

There's no strict file size limit, but very long videos (over 60 minutes) may take significantly longer to process.

Processing time depends on:

• Video length and resolution
• How many objects are being tracked
• Scene complexity (crowded scenes take longer)

Most videos under 5 minutes process in a few minutes. You can track progress in real-time.

Only the blurred regions are affected. The rest of the video maintains its original quality.

Output is exported in MP4 format with good quality preservation.

Your videos are stored securely on our servers for processing.

• Access is strictly limited to authorized personnel
• We do not use your videos to train AI models
• You can request deletion of your data at any time

No — the tool generates a new processed video. Your original file stays unchanged.

Use concrete, specific targets:

Good examples:

• "Blur all faces"
• "Blur everyone except the main speaker"
• "Blur all license plates"
• "Blur phone screens"

Tips:

• Keep prompts short and clear
• Avoid long paragraphs
• Be specific about what to blur

AI can miss objects in extreme conditions:

• Very small faces or objects
• Heavy motion blur
• Very dark scenes
• Extremely crowded frames

For sensitive content, we recommend reviewing the output before publishing. The tool is designed to help with anonymization but isn't 100% guaranteed in all conditions.
