CapBeat is a Premiere Pro plugin for word-by-word, social-style captions โ€” the kind you'd normally get from a web upload service, generated instead directly on your timeline with nothing ever leaving your machine.

What sets it apart: it's the only Premiere plugin that reliably captions music. Standard speech recognition is trained on spoken language, so a beat under the voice makes it guess wrong. CapBeat runs a vocal-separation step first (Demucs, open-sourced by Meta) to isolate the voice from the instrumental, then transcribes that โ€” turning a garbled 14-word guess into the complete, correctly-timed lyric.

Beyond captions, CapBeat also includes 19 drop-in object animations (fly-ins, pops, spins, true motion blur via Premiere's own Transform effect) applied with one click and zero manual keyframing, plus SRT export for any other workflow.

Free tier: full recognition quality (up to Whisper Large-v3), no watermark, videos up to 10 minutes, 5 animations. Pro (โ‚ฌ79 one-time, no subscription): music mode, all caption styles, all 19 animations with motion blur, unlimited video length, SRT export.

Everything โ€” transcription, vocal separation, rendering โ€” runs locally on Windows. No account, no cloud processing, no per-video cost.

CapBeat features and specs

php eventloop features and specs

  • Simple and lightweight
    The library provides a minimalistic implementation of an event loop in PHP, making it easy to understand and integrate into small projects without heavy dependencies.
  • Educational value
    As a straightforward PHP event loop implementation, it serves as a great learning resource for developers wanting to understand how event loops and asynchronous programming concepts work under the hood in PHP.
  • Non-blocking I/O support
    The library enables non-blocking I/O operations in PHP, allowing developers to handle multiple tasks concurrently without relying on multi-threading, which PHP does not natively support well.
  • Timer and periodic task support
    It provides built-in support for timers and periodic tasks, enabling developers to schedule recurring operations or delayed execution within the event loop.
  • Pure PHP implementation
    The library is written in pure PHP without requiring external C extensions, making it portable and easy to install across different PHP environments without special compilation steps.

Possible disadvantages of php eventloop

  • Limited community and support
    The project has a very small community with minimal stars, forks, and contributors on GitHub, which means limited peer support, fewer bug reports, and potentially slower issue resolution.
  • Not production-ready
    Given its small scale and limited adoption, the library may not be battle-tested enough for production environments where reliability, performance, and stability are critical.
  • Limited features compared to alternatives
    More established PHP async libraries like ReactPHP, AmpPHP, and others offer far more comprehensive ecosystems with HTTP servers, database clients, and stream handling that this library lacks.
  • Performance limitations
    Being a pure PHP implementation without leveraging extensions like ev, libuv, or swoole, the event loop may suffer from performance bottlenecks compared to extension-backed alternatives when handling high concurrency.
  • Poor documentation
    The repository has minimal documentation and examples, making it difficult for new users to understand the full API, edge cases, and best practices for using the library effectively.

Analysis of php eventloop

Overall verdict

  • php-eventloop is a lightweight event loop implementation for PHP that provides a solid, minimalistic solution for developers wanting to implement asynchronous, non-blocking behavior without adopting a full framework like ReactPHP or Amp. It's good for learning purposes and simpler use cases, though it lacks the extensive ecosystem, tooling, and production hardening of more established async libraries.

Why this product is good

  • Lightweight and simple to understand, making it easy to integrate into small projects
  • Useful for learning how event loops work under the hood in PHP
  • Minimal dependencies compared to larger async frameworks
  • Open source and available for inspection/modification on GitHub
  • Can be a good starting point for building custom async solutions

Recommended for

  • Developers learning about event-driven programming in PHP
  • Small projects needing basic async functionality without heavy dependencies
  • Educational purposes and understanding event loop internals
  • Prototyping simple non-blocking I/O operations
  • Developers who want full control over a minimal event loop implementation

Questions & Answers

As answered by people managing CapBeat and php eventloop.

What makes your product unique?

CapBeat's answer

CapBeat is the only Premiere plugin that reliably captions music. Standard speech recognition is trained on spoken language, so a beat under the voice makes it guess wrong. CapBeat runs a vocal-separation step first (Demucs, open-sourced by Meta) to isolate the voice from the instrumental, then transcribes that โ€” turning a garbled 14-word guess into the complete, correctly-timed lyric.

Why should a person choose your product over its competitors?

CapBeat's answer

It's lightweight, easy to use and has a completely free tier.

How would you describe the primary audience of your product?

CapBeat's answer

Video editors that edit reels and ads for social media as well as musicians that want to include their music in social media reels.

What's the story behind your product?

CapBeat's answer

I myself am a musician and always struggled with having good captions for my social media reels, so I created my own program that sets the lyrics apart from the music and reads the vocals cleanly โ€” something no other Premiere plugin could do. What started as a personal fix for my own uploads turned into CapBeat: still built by one person, still shaped by actually making music videos, not just watching other people struggle with them.

Which are the primary technologies used for building your product?

CapBeat's answer

  • Adobe CEP (Common Extensibility Platform) for the Premiere Pro panel
  • HTML/CSS/JavaScript (Node.js) for the interface, ExtendScript for the Premiere-side integration
  • Whisper (faster-whisper) for speech recognition, bundled and running fully locally
  • Demucs (Meta, open-source) for vocal/instrumental separation
  • ffmpeg for audio and video processing
  • Inno Setup for the Windows installer
