XSplit Stream Subtitles — Add Real-Time Translation to XSplit Broadcaster
XSplit Broadcaster is a powerful streaming and recording application used by professional streamers and content creators worldwide. While XSplit includes robust scene management, source layering, and streaming capabilities, it does not have built-in real-time subtitle generation. StreamTranslate fills this gap via XSplit's Webpage source — the equivalent of OBS's browser source — allowing you to add live translated captions to your stream in just a few minutes.
XSplit Webpage Source vs. OBS Browser Source
XSplit's Webpage source and OBS's Browser source work identically from StreamTranslate's perspective. Both render a URL in a transparent Chromium-based frame that overlays your stream content. StreamTranslate is fully compatible with both — there's no configuration difference on the StreamTranslate side.
Requirements
- StreamTranslate account — free trial at /upgrade
- XSplit Broadcaster (v4.0+)
- Active streaming platform account (Twitch, YouTube, X, and TikTok, etc.)
- Microphone set as primary input
Setup Guide: XSplit + StreamTranslate
Generate your overlay URL
Sign in to streamtranslate.live/control. Select your source language and target language for translation. Click Generate and copy the overlay URL.
Add a Webpage source in XSplit
In XSplit Broadcaster, click on your active scene. Go to Add Source → Webpage. A dialog will appear — paste your StreamTranslate overlay URL in the URL field. Set width to 1920 and height to 1080. Click OK.
Set source order and sizing
The Webpage source should be at the top of your source layer stack. Right-click it → Order → Bring to Front. Then right-click → Transform → Set to Canvas Size to ensure it covers the full 1920×1080 frame.
Configure streaming output
Go to Output → Set up a new output. Select your platform (Twitch, YouTube, X, and TikTok, etc.) and authorize your account. Set bitrate to 6000 Kbps for 1080p60 or 4000 Kbps for 1080p30. Click Start Broadcast.
Verify subtitles in stream preview
Speak into your microphone. Within 1–2 seconds, subtitles should appear at the bottom of your stream in the XSplit preview window. Check the preview in your browser to confirm they're visible to viewers.
XSplit tip: Lock the Webpage source after positioning by right-clicking → Lock Position. This prevents accidentally moving the subtitle layer while adjusting other sources during live streams.
XSplit Broadcaster Performance with Browser Sources
XSplit uses hardware acceleration by default for webpage rendering, which means the StreamTranslate overlay has minimal impact on your streaming performance. If you notice performance issues, check XSplit Settings → Advanced → Hardware Acceleration and ensure it's enabled for both video encoding and source rendering.
Supported Streaming Platforms
XSplit Broadcaster supports streaming to Twitch, YouTube Live, X, and TikTok, Facebook Gaming, and custom RTMP destinations including Kick. StreamTranslate works identically across all these platforms — the subtitle overlay is baked into the stream output before it's sent to any platform.
Frequently Asked Questions
Does XSplit Broadcaster have a built-in subtitle feature?
XSplit Broadcaster does not have native real-time subtitle generation. StreamTranslate integrates as a Webpage source inside XSplit, providing live translated captions on your broadcast.
How do I add a webpage source in XSplit?
In XSplit Broadcaster, go to Add Source → Webpage, paste your StreamTranslate overlay URL, set width to 1920 and height to 1080. The source will appear in your scene as a transparent overlay with live subtitles.
Does XSplit Broadcaster support browser sources like OBS?
Yes. XSplit calls it a Webpage source rather than a browser source, but it works identically — paste a URL and it renders the page as a transparent overlay in your scene.
