What is a screen recording API?

A screen recording API is a programmable interface that lets developers embed screen recording capabilities into their applications. Instead of users switching to a separate tool like Loom or OBS, they can record their screen, webcam, and audio directly within your product. The API handles capture via getDisplayMedia, server-side recording and storage, transcription, and publishing.

Can V100 record screen and webcam simultaneously?

Yes. V100's screen recording API supports composite recording that captures both the screen share and webcam feed simultaneously. The webcam feed appears as a picture-in-picture overlay on the screen recording. Position, size, and shape of the webcam overlay are configurable through the API.

How does V100 compare to Loom for async video?

Loom is a standalone async video product for end users. V100 is an API that lets developers build Loom-like functionality into their own applications. With V100, the recording, transcription, and viewing experience lives in your product under your brand. Loom requires users to leave your app and use the Loom interface. V100 gives you the building blocks; Loom gives you the finished product.

SCREEN RECORDING

Screen Recording API
Capture, Transcribe, Publish

Async video is replacing synchronous meetings for status updates, bug reports, product demos, and training content. Loom proved the format. V100 gives you the API to build it into your own product. Capture screens via getDisplayMedia, record server-side to encrypted S3 storage, transcribe with AI, generate automatic summaries, and publish to seven platforms -- all through a single REST API. Your users never leave your application.

The Async Video Opportunity

Loom was acquired by Atlassian for $975 million in 2023, validating async video as a product category. But Loom is a standalone product -- users leave your application to record and view videos. V100's screen recording API lets you build the same workflow into your own product, keeping users in your ecosystem.

Replace Synchronous Meetings

A 30-minute meeting costs 30 minutes times the number of participants. A 5-minute screen recording costs 5 minutes to record and 5 minutes to watch -- on the viewer's schedule. For status updates, bug reports, and walkthroughs, async video saves 60-80% of team time compared to live meetings.

Searchable Video Library

Every screen recording is automatically transcribed, making the spoken content searchable. Six months from now, when a new team member asks "how does the deployment process work," the answer is a search query away -- not a 30-minute meeting with someone who remembers.

Async Across Time Zones

Distributed teams cannot always find overlapping working hours. Screen recordings bridge the timezone gap. Record a product demo in San Francisco at 3pm, and your team in Tokyo watches it at 10am their time. No one loses sleep over a scheduling conflict.

How the Screen Recording Pipeline Works

V100's screen recording API handles the full pipeline from browser capture to published, transcribed video. Here is what happens at each stage.

Capture via getDisplayMedia

The V100 client SDK calls the browser's getDisplayMedia() API to capture the user's screen, a specific application window, or a browser tab. The user sees the standard browser permission dialog -- V100 does not bypass it. Audio capture includes both microphone input and system audio (where supported). If webcam composite is enabled, the webcam feed is captured simultaneously via getUserMedia().

Server-Side Recording to S3

Media streams are sent to V100's recording infrastructure via WebRTC. Server-side recording produces consistent, high-quality output regardless of the user's device. Recordings are stored in AES-256-GCM encrypted S3 buckets with optional data residency controls. Every recording receives an ML-DSA-65 Dilithium post-quantum digital signature for tamper-proof integrity verification.

AI Transcription and Summary

Once recording completes, V100 automatically transcribes the audio using Deepgram and Whisper engines. The transcription includes word-level timestamps and speaker identification. An AI summary is generated from the transcript -- a concise paragraph covering the key points, decisions, and action items mentioned in the recording. Both are available via the API within minutes of recording completion.

Multi-Platform Publishing

Publish recorded screen captures to YouTube, Vimeo, TikTok, LinkedIn, X, Facebook, and Instagram through V100's publishing API. The recording is automatically formatted for each platform's aspect ratio and duration requirements. Schedule posts for optimal engagement windows. Or embed directly in your application via V100's CDN-backed player with sharing controls.

Screen Recording Features

V100's screen recording API goes beyond basic capture. Here are the features that make it a production-ready async video infrastructure.

Webcam Composite

Record screen and webcam simultaneously with picture-in-picture. Configure the webcam overlay position (corner), size (small, medium, large), and shape (circle, rounded rectangle). The composite is rendered server-side for consistent output across devices.

Auto-Generated Captions

Every screen recording automatically receives captions in the spoken language plus any additional languages you configure. Captions can be burned into the video or delivered as SRT/VTT sidecar files. Essential for accessibility and for viewers watching without sound.

Trim and Edit via API

Trim the beginning and end of recordings, remove silence, and cut sections via the editing API. No video editing software needed. Users can also edit by deleting words from the transcript -- V100 removes the corresponding video segments automatically.

View Tracking

Track who has viewed each recording, how much they watched, and where they dropped off. Webhook events fire on first view, 50% watched, and completion. Build engagement analytics into your product without a separate analytics tool.

Access Controls

Control who can view each recording with link-level permissions, password protection, domain-restricted embedding, and expiration dates. Integrate with your existing auth system -- V100 validates viewer identity via JWT tokens before granting playback access.

CDN Delivery

Recordings are served via CloudFront CDN with adaptive bitrate streaming. Viewers get fast playback regardless of location. The embeddable player supports custom branding, playback speed controls, and chapter markers generated from the AI summary.

Integration Guide

Add screen recording to your application in three steps. The V100 client SDK handles the browser capture APIs. Server-side recording, transcription, and publishing happen automatically.

screen-recording.js

// npm install v100-sdk
import { V100 } from 'v100-sdk';

const v100 = new V100('YOUR_API_KEY');

// Start a screen recording session
const recording = await v100.screenRecording.start({
  captureScreen: true,
  captureWebcam: true,           // PiP webcam overlay
  webcamPosition: 'bottom-right', // 'bottom-left' | 'top-right' | etc.
  webcamSize: 'medium',           // 'small' | 'medium' | 'large'
  captureSystemAudio: true,      // Tab audio (where supported)
  transcription: {
    enabled: true,
    language: 'en',
    diarize: true
  },
  aiSummary: true,               // Generate AI summary on completion
  autoCaption: true              // Burn-in captions
});

// Stop recording
const result = await v100.screenRecording.stop(recording.id);

// result.recordingUrl  → "https://cdn.v100.ai/rec_abc123.mp4"
// result.transcriptId  → "tr_xyz789"
// result.summary        → "Eric demonstrated the new deployment pipeline..."

// Publish to YouTube
await v100.publish.create({
  recordingId: result.id,
  platforms: ['youtube'],
  title: 'Q1 Product Update',
  description: result.summary,
  visibility: 'unlisted'
});

Or use the REST API to manage recordings:

terminal

# Get recording with transcript and summary
curl https://api.v100.ai/v1/recordings/rec_abc123 \
  -H "Authorization: Bearer YOUR_API_KEY"

# Publish to multiple platforms
curl -X POST https://api.v100.ai/v1/publish \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "recordingId": "rec_abc123",
    "platforms": ["youtube", "linkedin"],
    "title": "Q1 Product Update",
    "scheduledAt": "2026-04-01T14:00:00Z"
  }'
