Phosphor is a new way to bring animation and video to the web. Starting with the video track of a standard QuickTime file, Phosphor creates cross platform, web-standards compliant assets which can be played in desktop and mobile browsers without plugins or even video decoding capabilities. As long as a browser supports Javascript and the ability to show images, it can display Phosphor content.

Phosphor makes it simple to add animated logos, screen captures, demonstrations, and more to your website. Unlike other options for motion on the web, Phosphor supports full alpha transparency and high resolution color. Phosphor opens your QuickTime movies and generates a set of standard HTML, javascript and image assets which can be embedded in a website. It’s no more difficult than adding videos, images or flash your website, but far more powerful. Helpful samples show you exactly what to do. For the more tech-savvy user, a powerful open-sourced framework can be extended to add interactivity and dynamic control.

- For video content only, no audio playback.
- Supports ProRes, h.264, mpeg and motion-jpeg movies.
- To use, you’ll need access to upload image and json assets to your web server, and import our small JavaScript library.
- Works best with animation, line art and short photorealistic videos.
- Playback framework opensourced under MIT license -


Release Notes:

• Now loads image sequences as source media
• Added rate setting for playback speed
• Fixes bug in alpha color shifting
• Moves playback to requestAnimationFrame() for better performance and battery life on mobile devices

When quality and performance matters... - I’ve seen some very kludgy ways to get good animations but this IS NOT one of them. Very impressed by the output and performance of the application. Saved our bacon on a client where everything went wrong with animated GIFS and their offshore development team. Turned the tide to a huge win. Thanks again for Phosphor.

👍 EXCELLENT Web Animation Tool!!! - Just WOW! I’ve been doing web dev for many years, and strive to create clean websites with HTML5, CSS3, javascript, and use frameworks all the time. But this is hands down the simplest and coolest web animation tool I have come across in a long time! Don’t get me wrong, there are some great tools out there for building animations for the web (Hype for one), CSS animation tricks, javascript libraries, and there's no substitution for a great properly compressed video (not using Flash) when it’s called for. But when you want to add a quick little web animation, and don’t have the time to create an indexed sprite image, write the code to take advantage of it, and integrate it into your site. Well then, Phosphor is for you. Phosphor has saved me so much time in my current project already that it has easily paid for itself 10X over! Yes, this is a real review, and no I don't work for the company. Keep up the great work Divergent Media, this product rocks! I'm just sad I didn't find this tool earlier.
