Avatar — Introduction & How It Works

R
Written by Ryan Hait-Campbell

Avatar is a new SignCaption feature that transforms audio, video, text, subtitles, or documents into signed ASL content using AI-generated signing avatars or human interpreters. It’s designed to help creators, educators, businesses, and Deaf-centered teams make their content more accessible, expressive, and easier to understand through sign language translation.

Unlike traditional captioning workflows, the Avatar feature builds directly on top of SignCaption’s existing subtitle editor. This means your content is first converted into editable subtitles and timing segments, then transformed into signed ASL output through a guided rendering workflow. The goal is to make the process simple, flexible, and scalable — whether you’re translating a short social clip, educational lesson, presentation, or long-form media project.

The Avatar feature supports multiple content types including:

  • Video uploads (mp4, mov, webm)

  • Audio uploads (mp3)

  • Text and subtitle files (txt, srt)

  • Document uploads (docx)

Once uploaded, SignCaption automatically processes your content, extracts subtitles or speech, and prepares everything inside the editor for review before rendering into ASL.

How To Use the Avatar Feature

Step 1 — Open Avatar From The Dashboard

After logging into SignCaption, navigate to the dashboard and locate the Avatar card inside the Quick Actions section.

The Avatar card allows you to begin a new ASL translation project directly from the dashboard. You can upload:

  • Audio

  • Video

  • Subtitle files

  • Text files

  • Documents

Click Upload to begin creating a new Avatar project.

Step 2 — Upload Your Content

After clicking Upload, the Avatar upload modal will appear.

You can:

  • Drag and drop your file into the upload area

  • Or click Choose file to manually select a file from your computer

Supported file types include:

  • mp3

  • mp4

  • mov

  • webm

  • docx

  • txt

  • srt

Once selected, click Submit to begin processing your project. During upload and processing, SignCaption may automatically:

  • Extract audio

  • Generate speech-to-text

  • Parse subtitles

  • Create subtitle timing segments

Processing time depends on file size and complexity. Your project will automatically appear in your dashboard once ready.

Step 3 — Open Avatar From The Dashboard

Once processing completes, your project opens inside the SignCaption editor.

Inside the editor:

  • The left side contains subtitle timing blocks

  • The center displays the transcript and editor preview

  • The right-side panel contains Avatar controls

Click the Avatar tab in the right panel to begin configuring your ASL rendering settings.

The Avatar feature works from the subtitle layer generated during upload. Before continuing, carefully review your subtitles for:

  • Accuracy

  • Timing

  • Grammar

  • Missing captions

Accurate subtitles are important because the ASL generation process relies directly on this text.

Avatar Features

AI Generated Signing Avatars

The Avatar allows you to generate signing avatars automatically using AI.

Inside the Signer Type section, choose:

  • AI Generated — automated avatar rendering

  • Human Interpreter — request a human signer workflow

AI-generated avatars are designed for faster turnaround times and lower cost, while human interpreter workflows are designed for higher-touch signing projects.


Avatar Selection

When AI Generated is selected, it displays avatar preview options that allow you to choose your preferred signing appearance before rendering.

This helps tailor the experience depending on:

  • Content tone

  • Audience

  • Educational context

  • Brand style


Dynamic Pricing & Time Estimates

Before submitting your project, the Avatar feature provides:

  • A quoted amount

  • Estimated delivery time

  • Subtitle segment totals

Pricing may vary depending on:

  • Content length

  • Signer type

  • Rendering complexity

  • Delivery format

The system is designed to provide clear expectations before payment and rendering begin.


Delivery Formats

Once fulfilled, the Avatar feature supports multiple output modes including:

  • Picture-in-Picture (PIP) — signer overlay on top of the original content

  • Side-by-Side — signer displayed next to the original content

  • Signed video only — isolated signing output

Users can preview and download their preferred render format directly from the editor.


Best Practices Before Rendering

Before submitting your Avatar order:

  • Double-check subtitle accuracy

  • Ensure sentence timing looks correct

  • Review punctuation and formatting

  • Verify no subtitle segments are missing

  • Confirm your selected signer type and avatar preference

Once submitted, selections may become locked during rendering and production.


Processing & Order Tracking

While the Avatar job is processing:

  • Active jobs appear in the top navigation processing area

  • Projects are labeled inside Recent Activity

  • Orders can be viewed from the new Orders section in the user dropdown

Users can return later while processing continues in the background.


Why The Avatar Feature Exists

The Avatar feature is part of SignCaption’s broader vision of building accessibility-first, but engagement-driven communication tools for sign language media. Rather than treating accessibility as a static compliance feature, Avatar aims to make signed content easier to create, scale, share, and integrate into modern creator workflows.
