# What are Chromium browsers, and why does Subclip recommend them?

Chromium browsers are browsers built on the Chromium engine. They usually provide the strongest support for modern media and compute APIs needed for heavy in-browser video and AI workflows.

**What are Chromium browsers?**
Chromium is the open-source browser project that powers multiple browsers. Chromium-based browsers include Chrome, Microsoft Edge, Brave, Opera, Arc, Comet, and Dia.

**Important point**
When Subclip says "use Chromium," it does **not** mean "Chrome only." It means any modern, up-to-date browser built on Chromium can work well.

**Why this matters for Subclip**
Subclip runs many heavy workflows directly in your browser, including local media processing and client-side rendering paths. Those workflows depend on modern browser APIs, codec pipelines, and stable hardware-accelerated execution.

For high-throughput tasks, Chromium browsers are usually the most consistent choice in production because they tend to have stronger support and more predictable behavior for:
- modern media APIs used in local video/audio processing (including mux/demux and encode/decode workflows)
- WebCodecs-based media acceleration paths
- WebAssembly/Web Workers pipelines used by browser-side processing tools
- newer graphics/compute paths used by ML-heavy browser applications
- large local file handling and long-running tab stability under sustained workloads

**Subclip context (short summary)**
In Subclip, browser capability directly affects reliability and speed for workflows such as:
- [Generate Subtitles](/tools/generate-subtitles)
- [Dynamic Viral Captions](/tools/dynamic-viral-captions)
- [AI Text to Speech](/tools/text-to-speech)
- [AI Video Dubbing](/tools/dubbing)
- [AI Video Editor](/tools/ai-video-editor)
- AI clipping and timeline-style local rendering workflows in browser

These flows can involve local model execution paths and client-side rendering operations that rely on the browser having robust access to modern system-facing web APIs.

**Do I need to install anything extra?**
No extra plugin is required for core usage. In most cases, updating to the latest stable desktop Chromium browser is enough.

**Practical recommendation**
If you see unstable playback, export, or generation behavior:
1. Update to the latest version of your Chromium browser.
2. Retry in Chrome or Edge as a baseline check.
3. Close heavy background tabs/apps to free memory.
4. Re-run the same job in [Generate Subtitles](/tools/generate-subtitles) or [Dynamic Viral Captions](/tools/dynamic-viral-captions).
