The latest version of WebViewer Video brings full-featured and integrated audio-video redaction to the PDFTron platform. Quickly redact an entire frame or many frames and parts of the audio track!
Even better, the PDFTron SDK lets you embed video redaction directly into an enterprise digital workflow or commercial product – without relying on a server to redact videos. As a result, developers can release secure features faster and leverage other benefits of client-side processing, including improved reliability and performance from on-demand processing.
This article examines the modern redaction workflow and how we designed WebViewer Video to make video/audio redaction seamless and easy.

New video redaction lets you redact video frames, audio, or both in the same UI.
Redaction permanently removes sensitive information in a video or document, such as personally identifiable material, including emails and credit card numbers, by deleting or completely obscuring underlying content.
Redaction was once performed manually, with scissors, black marker, redaction tape, photocopiers, and OCR scanning technology. Today, redaction can be done electronically and even automatically, on all types of digital content.
For example, videos might need to be redacted to adhere to compliance and privacy of information laws. While it may seem easier to destroy an entire record or video rather than selectively redact it, some materials must be legally preserved or may contain other data that needs to be retained.
Users can redact a video in many ways – they can target an entire frame, the entire video, parts of the audio track, or the entire audio track. View modes let you review frame by frame if you want, and help you focus on specific areas as you review: video only, the audio track only, or both video and the audio track at the same time.
We also give you complete control over each person's view based on their role, personal preference, or workflow, within a developer-friendly component fully customizable to your unique industry or regional requirements.
Let’s look at how users can apply redactions to videos and audio tracks using WebViewer Video.
Different views and modes help you review videos efficiently, so you don’t miss any sensitive content. As a developer, you can connect viewing modes to user permissions or roles to control the experience.
WebViewer Video lets you toggle the frame-by-frame view, so you can review a video the way it suits you, one frame at a time or via multiple frames.

With viewing modes, you can choose to review video content only or video along with the audio track at the same time.
Users can redact an entire frame (the default approach), as well as control the duration of the redaction.
To redact a video frame using WebViewer Video:
The audio redaction tool lets you redact a video audio track or part of a track. Like frame redactions, you can control the duration of the redaction.

You can see the audio form visualized along the annotation timeline. Users can easily select a region of the audio track and remove or redact areas of the track directly in the browser.
This feature makes it easy to spot and redact sensitive audio content that shouldn’t be disclosed, shared, or stored.
