Erase Objects

Remove unwanted objects, people, logos, or any elements from your videos using AI. Bria Object Eraser intelligently fills in the background where the object was, making it disappear completely.

Erase Objects is the Studio workflow for removing something unwanted from a short video while keeping the rest of the shot. Use it for bystanders, logos, signs, boom mics, cups, clutter, background distractions, or small objects that pull attention away from the edit.

Chat Video Pro uses Bria Object Eraser to identify what should disappear, remove it, and fill the empty area with a generated background that matches the surrounding footage.

What This Tool Is For

Erase Objects is for removing the selected object and preserving the rest of the scene.

Use it for:

  • Removing a bystander from b-roll.

  • Cleaning up a product shot.

  • Removing a logo, sign, timestamp, or watermark where you have the rights to do so.

  • Removing a mic boom, tripod, cable, cup, tag, or small production mistake.

  • Cleaning short social clips before delivery.

  • Testing whether an object can be removed before spending time on manual cleanup.

Do not use Erase Objects when you want to keep a subject and remove the entire background. That is a rotoscoping task, so use Rotoscope instead.

Erase Objects answers: "What should disappear?" Rotoscope answers: "What should stay?"

When To Use It

Use Erase Objects when the unwanted item is visible, describable, and surrounded by enough background for the model to rebuild the area.

Goal
Why Erase Objects helps

Remove a passerby

Cleans up b-roll without reshooting.

Remove a logo or sign

Makes footage less distracting or more brand-safe.

Remove gear from frame

Cleans up boom mics, stands, cables, and accidental equipment.

Remove clutter

Simplifies interviews, desks, product shots, and social clips.

Remove a small foreground object

Lets the surrounding texture fill in naturally.

Studio Path

The fastest route is through Studio.

  1. Open Studio.

  2. Choose Erase Objects from the Post-Production department.

  3. Load a video from upload, Recents, or your Premiere timeline.

  4. Choose Text or Point selection.

  5. Describe or mark what should be removed.

  6. Choose an output format if needed.

  7. Click Erase Object.

  8. Review the result and send it back to your chat/library.

Studio opens the video editor directly in Bria Object Eraser mode, so you do not need to select the model manually.

Erase Objects has a hard 5-second video limit. This comes from the Bria video eraser API. Trim your clip to the exact moment you need before using this workflow.

Classic/Editor Path

You can also use Erase Objects from the classic video editor path:

  1. Import or generate a short video.

  2. Click Edit on the video thumbnail.

  3. Choose Bria Object Eraser from the model selector.

  4. Select what to erase using Text or Point mode.

  5. Choose output format.

  6. Click Erase Object.

This path is useful when you are already working from a chat result. For new cleanup work, Studio is the better starting point because it opens the correct tool immediately.

Controls And Constraints

Control
What it does

Text

Removes an object based on a written description.

Point

Lets you click the object directly. Click marks erase points; Shift-click marks protect points.

Output Format

Chooses the result codec/container: H.264, H.265, ProRes, or VP9.

Erase Object

Starts the Bria cleanup job.

Current constraints:

Constraint
Detail

Model

Bria Object Eraser.

Maximum duration

5 seconds. This is a hard limit.

Frame rate

Bria expects 20-30 fps. Chat Video Pro prepares incompatible clips automatically when possible.

Best source

Short, stable, well-lit footage with a clear object to remove.

Selection methods

Text or Point. Box selection is not used for Bria.

Audio

The workflow preserves audio when processing.

Reference images

Not used. Erase Objects works from the source video and your selection.

Output Formats

Format
Best for

H.264 (MP4)

Most compatible, best default for review and general editing.

H.265 (MP4)

Smaller files when your workflow supports H.265.

ProRes (MOV)

Higher-quality editing handoff, larger files.

VP9 (WebM)

Web-oriented output.

If you are unsure, use H.264. If you are sending the result into a heavier finishing workflow and file size is not a concern, ProRes can be a better handoff format.

Selection Methods

Text Selection

Use Text when the object is easy to describe.

Good prompts:

Text mode works best when there are not many similar objects in the shot. If there are multiple people, signs, cups, or cars, include location and visual details.

Less effective:

Point Selection

Use Point when the object is hard to describe or when you want more direct control.

Point mode behavior:

  • Click on the object to mark it for erasure.

  • Add multiple erase points for larger or irregular objects.

  • Shift-click areas you want to protect.

  • Use protect points when the model is removing nearby detail you want to keep.

  • Clear all points and try again if the selection gets confusing.

Best Practices

Trim To The Exact Problem

Because the workflow is limited to 5 seconds, trim aggressively. Do not send extra lead-in or tail frames unless they are needed for the cleanup.

Good uses:

  • A 3-second shot where a person crosses the background.

  • A 5-second product close-up with a tag or hand to remove.

  • A short interview moment with a cup or cable in frame.

Bad uses:

  • A 20-second clip with a distraction for only 2 seconds.

  • A long handheld shot with the object moving behind multiple subjects.

  • A wide shot with a tiny object that is barely visible.

Remove One Clear Thing At A Time

Bria works best when the instruction is focused. If you need to remove several unrelated objects, do separate passes or start with the most distracting object.

Better:

Riskier:

Give The Model Background To Rebuild

Object removal is easier when the area behind the object is predictable: wall, floor, sky, desk, road, grass, or a repeated texture.

Harder cases include:

  • Faces behind the object.

  • Text or signs behind the object.

  • Complex reflections.

  • Fast camera motion.

  • Objects crossing detailed hands, hair, or patterned clothing.

  • Large objects covering a big portion of frame.

Use Protect Points

If Point mode starts erasing nearby details, Shift-click areas you want to protect. This is useful when removing an object close to a face, product edge, logo you want to keep, or another person.

Review The Fill, Not Just The Removal

A result can remove the object but still look wrong if the generated fill is smeared, warped, or inconsistent. Watch the entire cleaned clip, especially the frames before and after the object moves.

Examples

Clean B-Roll

  • Source: Street b-roll with a passerby in the background.

  • Selection: the person walking in the background.

  • Result: Cleaner shot for a brand, travel, or corporate edit.

Remove Production Gear

  • Source: Interview clip with a boom mic entering the top of frame.

  • Selection: the microphone boom at the top of the frame.

  • Result: Usable interview moment without sending the clip to a manual cleanup pass.

Product Shot Cleanup

  • Source: Product video with a sticker, tag, hand, or stray object.

  • Selection: Point mode on the item or prompt the tag on the product.

  • Result: Cleaner product shot for ads, landing pages, or social content.

Remove A Logo Or Sign

  • Source: Background sign or corner logo.

  • Selection: the logo in the bottom right corner.

  • Result: Less distracting footage, assuming you have the right to remove it.

Troubleshooting

The video is longer than 5 seconds

Trim it first. Bria Object Eraser will not process clips longer than 5 seconds. If only one part of the shot needs cleanup, export or import just that section.

The model removes the wrong object

Use a more specific prompt or switch to Point mode. Include location, color, size, or relationship to the frame:

The object is only partly removed

Use Point mode and add more erase points on the remaining pieces. For text mode, name the full object more clearly:

The background fill looks unnatural

Try a shorter clip, a more stable section, or a shot where the hidden background is simpler. Bria has to invent what was behind the object, so complex backgrounds are harder.

Nearby details are disappearing

Use protect points with Shift-click in Point mode. Mark the object with erase points, then mark nearby details that should stay.

The clip needs frame-rate conversion

Bria expects 20-30 fps constant-frame-rate video. Chat Video Pro prepares the clip automatically when possible. If preparation fails, try exporting a short H.264 MP4 from Premiere at 24, 25, or 30 fps and use that as the source.
