This page hopes to outline media related projects. This should help keep developers on the same page in regards to improved media handling and key infrastructure support tools. There is also a mailing list: Wikivideo-l.
Kaltura.org many media components are developed in an open source development partnership with Kaltura.
Visit the MetaVidWiki extension page for more info on the metavid extension. For more info on the metavid project you can visit metavid.org. Metavid integrates semanticMediaWiki, interfaces for editing temporal text data such as transcripts and semantic annotations, and interfaces for searching this temporal media metadata.

Add Media Wizard 
Add Media Wizard is the tool for adding media to pages or sequences. Abstracts the remote repository architecture to work with the new upload api.
- See Add Media Wizard for more info.
Shouldn't this page mention Extension:UploadWizard?
How does it fit with these other things?
Firefogg integration 
New Upload API 
Based on the initial work by vodaphone and then Bryan Minh; the new upload api abstracts out the Special:Upload page into a few classes and then extends the mediaWiki an API to support upload contributions. My work is focused on bring that branch up-to-date and adding chunk support for breaking POST requests into 1 meg resumable chunks. The chunk support enables firefogg to progressively upload video content with resume on reset POST requests. also see the new-upload branch
Sequencer / Video Editor / Slide Show Maker

Wiki@Home / derivatives extension 
The Wiki@home extension provides distributed transcode and sequence flattening infrastructure.
Clip Edit 
Can be thought of as the figure editor or "clip" editor. We eventually want to this to be a feature rich layout and layer manipulation tool. Manipulations will be stored in a "stack" and not modify the underlining assets. This lets collaboration occur around the figure editing process. It will be usable inline figures in articles and for building "key frames" in sequences.
Currently just crop & video trimming is supported but the base pixastic-lib has been imported with plans to add in hooks to that library.
The same export mechanism for frame serving and exporting video sequences will drive the "flattening" of these figures (since the edit stack will likely include canvas manipulations we will render the figure server side or on the client and use that for display.
These "figures" or "clips" will be template for localization and reuse. All manipulations will be stored in floats (rather than pixel positions) to facilitate seamless scaling up by using higher resolution image assets. This documentation will be fleshed out a bit as the code is ;) We will try and use SMIL like descriptions for crops and filters.
SVG parametrization 
Also part clipEdit system we will want to support svg parametrization. ie highlighting a map element by chaining its color or translating text in figures.
