NotebookLM Video Overviews: What They Are & How to Clean Them Up (2026)

What Are NotebookLM Video Overviews?

Video Overviews are one of NotebookLM's most impressive features. Feed the tool your research notes, PDFs, web pages, or Google Docs, and it generates a narrated explainer video — complete with visuals, transitions, and an AI-generated voiceover that walks through your content.

Think of it as an AI-produced presentation that would take a human hours to storyboard, record, and edit. NotebookLM does it in minutes. The result is an MP4 file you can share, embed, or present.

The catch: every exported video carries two watermark elements that mark it as a free-tier product. Removing them officially requires NotebookLM Ultra at $250/month. This article covers what Video Overviews actually produce, where the watermarks sit, and how to clean them up for free.

Standard vs Cinematic Mode

NotebookLM offers two video generation modes:

Standard Mode

The default. It produces a clean, informational video with slides, bullet points, and narration. The visual style is functional — designed for educational content, meeting summaries, and research walkthroughs. Output is typically 720p or 1080p.

Cinematic Mode

A newer addition that applies a more polished visual style — smoother transitions, richer color grading, and a more "produced" feel. The content is the same, but the presentation quality is higher. Think documentary-style rather than slide deck.

Both modes carry the same watermarks in the same positions. The cleaning process is identical regardless of which mode you use.

The Two Watermarks: Exactly What You're Dealing With

Every Video Overview export carries two distinct watermark elements:

1. The Persistent Logo Overlay

A "NotebookLM" badge sits in the bottom-right corner throughout the entire video. It's always visible, from the first frame to the last. The exact pixel coordinates depend on resolution:

Resolution	X, Y (top-left of watermark)	Width × Height	Coverage
1080p (1920×1080)	x=1104, y=656	770 × 62 px	~2.3% of frame area
720p (1280×720)	x=736, y=437	513 × 41 px	~2.3% of frame area

The watermark area is proportionally consistent across resolutions — roughly 2.3% of the total frame, always anchored to the bottom-right.

2. The "Made with Google" End Card

The final 2.5 seconds of every video are replaced with a full-screen "Made with Google" splash. This isn't a subtle badge — it's an entire card that fills the frame, completely replacing your content for the closing moment.

For a 60-second video, that's over 4% of your total runtime consumed by branding. For shorter videos, the proportion is even worse.

How to Remove Both Watermarks (Free, 60 Seconds)

Our Video Watermark Remover handles both elements in a single pass. Everything runs in your browser via FFmpeg compiled to WebAssembly — your video file never leaves your device.

Step 1: Export your Video Overview

In NotebookLM, open your Video Overview and download the MP4 file. Note whether it's standard or cinematic — the cleaning process is the same either way.

Step 2: Open the tool

Go to notebooklmremover.org/video. No account, no sign-up.

Step 3: Drop your file

Drag your MP4 onto the upload zone. The tool detects the resolution automatically and selects the correct watermark coordinates.

Step 4: Choose your options

Before processing, you can configure:

• Trim ending (on by default) — removes the 2.5-second "Made with Google" end card
• FPS — keep original (30fps) or reduce to 15fps for smaller file size
• Cinematic enhancement — applies a subtle color grade (contrast +5%, brightness +2%, saturation +10%) if you want a more polished look

Step 5: Process and download

Click "Remove Watermark." The tool runs FFmpeg's delogo filter over the watermark region and trims the tail. Processing takes 30–90 seconds depending on video length and your device. Download the cleaned MP4 when done.

Under the Hood: How the Removal Works

The tool uses a precise, multi-step pipeline:

1. Resolution detection — FFmpeg probes the video to determine if it's 1080p or 720p, then selects the matching watermark coordinates from a built-in lookup table
2. Delogo filter — FFmpeg's delogo filter is applied to the watermark region. This interpolates the surrounding pixels to reconstruct what the frame would look like without the overlay. The filter runs on every frame of the video.
3. Tail trim — if enabled, the last 2.5 seconds are cut (-t duration-2.5), removing the "Made with Google" end card entirely
4. Re-encoding — the video is re-encoded with libx264 at CRF 18 (high quality) with the fast preset. Audio is stream-copied (zero quality loss on audio). On mobile devices with large files, the tool automatically drops to CRF 24 with ultrafast preset to avoid memory issues.

The result is a visually clean video where the watermark region blends naturally with the surrounding content.

Tips for Best Results

Before exporting from NotebookLM

• Choose your sources carefully — the quality of the video is directly tied to the quality and relevance of your source materials. Focused, well-organized sources produce better narratives.
• Prefer 1080p export — higher resolution gives the delogo filter more surrounding pixel data to work with, producing cleaner reconstruction
• Keep videos under 5 minutes — longer videos mean longer processing time in the browser. If you have a 20-minute video, expect a few minutes of processing.

After cleaning

• Spot-check the bottom-right corner — scrub through a few points in the timeline to confirm the watermark area looks natural
• Check the ending — make sure the video ends where your content ends, not at a random cut
• File size — the cleaned video may be slightly larger or smaller than the original depending on your FPS and quality settings. CRF 18 at 30fps produces files roughly similar in size to the original.

Frequently Asked Questions

Does cleaning work on both standard and cinematic Video Overviews?

Yes. Both modes place the watermark in the same position at the same size. The tool handles either one identically.

Will the cleaned video look different from the original?

The watermark region is reconstructed using surrounding pixels, so there may be very subtle blending in that small corner area. The rest of the video — 97.7% of every frame — is untouched. Most viewers won't notice any difference.

Can I process a Video Overview on my phone?

Yes, but with caveats. The tool detects mobile devices and automatically reduces encoding quality for large files (>30MB) to avoid memory issues. For the best experience and fastest processing, use a desktop browser. Videos under 30MB work well on most modern phones.
