Bria Video Eraser: AI-Powered Object Removal API

Edited by Segmind Team on December 27, 2025.

What is Bria Video Eraser?

Bria Video Eraser is an AI-powered model built to remove objects from videos while recreating the background with a high level of precision. Its mask-based detection capability analyzes each frame to identify and erase selected elements, such as watermarks, logos, objects, or even people; the second step involves reconstructing the surrounding environment to blend seamlessly with the scene. Bria Video Eraser runs asynchronously, and preserves the video’s original audio, supporting clips up to 5 seconds long with a resolution of 750p. Its efficiency makes it highly useful for developers working on automated content moderation, e-commerce product visuals, or creative editing tools that need accurate, frame-level corrections without the laborious task of manual adjustments.

Key Features of Bria Video Eraser

• •Mask-Based Object Removal: The process supports uploading a mask video to define exact regions that need to be erased, as this ensures pixel-level precision.
• •Intelligent Background Reconstruction: The model's AI capabilities fill removed areas with contextually appropriate background content across all frames.
• •Audio Preservation: The model effectively maintains original audio tracks, crucial for narrated content or ambient sound.
• •Multiple Output Formats: It supports MP4 (H.264/H.265), WebM (VP9), MOV (H.265/ProRes), MKV, and GIF for diverse platform requirements.
• •Asynchronous Processing: It offers efficient API handling for batch operations and large-scale video editing workflows.
• •Auto-Trim Capability: It automatically processes the first 5 seconds of longer videos for rapid prototyping.

Best Use Cases

• •Content Moderation: It precisely removes inappropriate objects, logos, or sensitive elements from user-generated videos before they are published.
• •E-commerce & Product Videos: Utilize it to erase distracting backgrounds, unwanted reflections, or competing products from demo footage.
• •Social Media & Marketing: It is perfect to clean up brand videos by removing watermarks, timestamps, or background elements that detract from messaging.
• •Film & Creative Production: It comes in handy to quickly remove boom mics, equipment, or modern elements from historical footage during pre-production review.
• •Real Estate & Property Tours: Create aesthetic virtual property walkthroughs by eliminating personal items, clutter, or staging elements.

Prompt Tips and Output Quality

Mask Creation Best Practices:

• •Use high-contrast masks: white for removal areas, black for preservation for the clearest results.
• •Ensure mask video precisely matches input video dimensions and frame rate.
• •Create precise masks since overly large masks may remove unintended background elements.

Input Video Optimization:

• •Provide high-definition source videos (720p or higher) for superior background reconstruction.
• •Stable footage produces better results than shaky or rapidly moving camera work.
• •Well-lit scenes allow the AI to understand textures and patterns to fill out the erased regions with perfection.

Parameter Recommendations:

• •Enable preserve_audio for videos with voiceovers, music, or important ambient sound.
• •Choose mp4_h264 for broad compatibility or webm_vp9 for web-optimized delivery.
• •Use auto_trim during development to quickly test mask accuracy before processing full clips.

# Bria Video Eraser: Effective Usage Guide

Bria Video Eraser is an AI-powered object removal API that seamlessly removes unwanted elements from video clips (up to 5 seconds at 750p) using mask-based detection. It preserves audio, reconstructs backgrounds, and exports in a variety of codecs. This guide will help you choose the right parameters for different applications.

## 1. Core Parameters & Recommended Settings

- **video_url (required)**  
  Use a publicly accessible, high‐definition (720p+) URL for best erasure and background fill quality.

- **mask_url (required)**  
  Supply a matching mask video (white = erase, black = keep). Ensure identical dimensions, frame rate, and duration.

- **preserve_audio (boolean)**  
  – Content Moderation & Marketing: `true` to keep narration or ambient sound.  
  – Raw Visual Demos: `false` to strip audio when only visual output matters.

- **auto_trim (boolean)**  
  – Rapid Prototyping: `true`   
  – Final Processing: `false` (trim locally for full-length clips).

- **output_container_and_codec (enum)**  
  – Broad Compatibility: `mp4_h264`  
  – Web Embedding: `webm_vp9`  
  – Mobile/Hevc-ready Platforms: `mp4_h265` or `mov_h265`  
  – Archival/Editing Workflows: `mov_proresks`  
  – Social GIF Previews: `gif`

## 2. Use Cases & Parameter Mapping

1. **Content Moderation**  
   • preserve_audio: true  
   • auto_trim: false  
   • codec: mp4_h264  

2. **E-commerce/Product Demos**  
   • preserve_audio: false (if background music isn’t critical)  
   • auto_trim: true (5 s previews)  
   • codec: webm_vp9  

3. **Social Media & Marketing**  
   • preserve_audio: true  
   • auto_trim: true (quick tests)  
   • codec: gif (teasers) or mp4_h265  

4. **Film & Creative Pre-Production**  
   • preserve_audio: true  
   • auto_trim: false  
   • codec: mov_proresks  

## 3. Best Practices

- Create precise, high-contrast masks in tools like After Effects or OpenCV.  
- Provide stable, well-lit footage to improve AI background fill consistency.  
- For longer clips, pre-trim locally rather than rely solely on `auto_trim`.  
- Test with `auto_trim: true` during mask tuning, then switch off for final exports.  
- Always match mask and source dimensions/frame rate to avoid processing errors.

By aligning these settings to your workflow—whether it’s rapid prototyping or high-quality production—you’ll maximize the power of Bria Video Eraser for clean, professional video results.  

What video resolutions and lengths does Bria Video Eraser support?

Bria Video Eraser model processes videos up to 750p-resolution and 5 seconds in length. For longer videos, enable the auto_trim parameter to automatically process the first 5 seconds, or pre-trim your footage before adding it to the model for processing.

How do I create the mask video?

Generate a mask video where white pixels indicate areas to remove and black pixels represent areas to preserve. The mask must match the input video's dimensions, frame rate, and duration. You can create masks using video editing software such as 'After Effects', 'DaVinci Resolve', or programmatically with libraries like OpenCV.

Will the eraser work with moving objects?

Yes, the AI tracks objects across frames. However, the best results occur with moderate movement; fast motion or frequent occlusion may affect reconstruction quality. Stable camera work and good lighting significantly improve tracking accuracy.

Can I remove multiple objects simultaneously?

Bria Video Eraser is exceptional when it comes to processing and removing multiple objects simultaneously. Create a mask that highlights all target objects in white, and the model will remove all marked regions in a single processing pass.

What happens to audio during processing?

By default, original audio is preserved (preserve_audio: true). The model maintains audio synchronization and quality throughout the erasure process, ensuring no drift or distortion.

Which output format should I choose?

Use mp4_h264 for maximum compatibility across devices and platforms; select webm_vp9 for web embedding with efficient compression; and mp4_h265 (H.265/HEVC) for higher quality at smaller file sizes when target platforms support it.
