Overview

Batch Video Watermark allows you to quickly overlay custom text watermarks onto up to five video files simultaneously. With precise controls over text position, font size, color, opacity, margins, background styling, and timing, you can easily protect your video content or add consistent branding across multiple clips in a single run.

When to Use

  • •When you need to apply a consistent brand name or copyright notice across multiple promotional videos at once.
  • •When protecting original video clips from unauthorized sharing by adding a semi-transparent text overlay.
  • •When adding timed text labels or captions that only appear during specific segments of your video files.

How It Works

  • •Upload up to five video files (up to 100MB each) that you want to watermark.
  • •Enter your custom watermark text and configure its appearance, including position, font size, color, opacity, and background styling.
  • •Set optional parameters such as start/end times for the watermark display or choose an animation mode like horizontal or vertical scrolling.
  • •Click the process button to apply the watermarks and download your updated video files.

Use Cases

Content creators adding a subtle '@username' handle to the bottom-right corner of their social media clips.
Videographers applying a temporary 'DRAFT' overlay to client preview videos with a specific start and end time.
Educators batch-labeling lecture recordings with course codes using scrolling text to prevent screen recording.

Examples

1. Social Media Branding for Content Creators

Social Media Manager
Background
A social media manager needs to upload five short promotional videos to multiple platforms and wants to ensure their brand handle is visible on all of them.
Problem
Manually editing each video in a heavy video editor to add a watermark is tedious and time-consuming.
How to Use
Upload the five MP4 videos, type the brand handle in the Watermark Text field, set the position to bottom-right, adjust the opacity to 0.7, and check 'Keep Original Names'.
Example Config
Text: '@MyBrandName', Position: 'bottom-right', Opacity: 0.7, Keep Original Names: True
Outcome
All five videos are quickly processed with a clean, semi-transparent brand handle in the bottom-right corner, ready for immediate upload.

2. Protecting Client Preview Clips

Freelance Videographer
Background
A videographer wants to send three draft clips to a client for review but wants to prevent unauthorized distribution by overlaying a prominent 'PREVIEW ONLY' warning.
Problem
The watermark needs to be highly visible, have a dark background for readability, and only appear after the intro sequence.
How to Use
Upload the draft videos, enter 'PREVIEW ONLY' as the text, set the position to center, choose a font size of 48px, set background opacity to 0.5, and set the start time to 5 seconds.
Example Config
Text: 'PREVIEW ONLY', Position: 'center', Font Size: 48, Background Opacity: 0.5, Start Time: 5
Outcome
The client receives videos where a clear, centered 'PREVIEW ONLY' watermark with a dark background overlay appears exactly 5 seconds into the playback.
