         DirectShow support is here! Granted there are a few issues with reading the file contents (does anyone know how to get the frame rate of a clip in DirectShow?). Tonight I also added support for loading and saving user preferences. Next is a render pipeline overhaul, and adding more node types!

         DirectShow support is %75 done! This will allow Win32 builds to import .avi, .wmv, .asf, .mpg, etc. files at blazing speeds. And more good news. We have procured a PowerMac G4 to develop on. Not a speedy machine (800Mhz with 512 MB RAM) but it will work for a testing builds. And we also have a SGI O2 on the way, so we may now begin building ports for Linux, Irix, and OSX. Forums are up as well!

         Speed issues solved! Video clips can now be played back at faster than real time! PyInline is a great tool, it allows us to inline C code directly into the Python code. FreeImage is now used for playback as well. Next up, fixing a few issues with PNG and TIFF files, and then adding full featured nodes. Color Grading included!

         Nodes can now be linked, and all the data is automatically updated in the database. Rendering now follows the node paths as well. The main framework is almost done. Tomorrow's coding project will be a GUI interface to the node properties, and making sure that all node properties are updated on the server.

         Big speed boost in the GUI code last night. After banging my head on the wall for awhile I came to the understanding that streaming every thumbnail for the GUI to the GPU every time it is needed is going take way too much power. It is better to stream the data to the card once, and use the memory on the video card as a cache. Tonight I plan to put all of this in a single class that will manage the video memory and automatically stream data to the card as needed. There will also be an option to limit the video memory being used by the application. Still the average gaming card should be able to cache a full 190 frames of SD video. The release date may be a bit delayed. But if nothing else, CVS will be up by March 1st.

         Finally I have taken the time to update this page a bit and start blogging on the progress of Positron. Since node based compositors and NLE systems both share allot of the same code, I decided to start with the node based compositing end of things and work from there. Currently nodes are visible and movable in the node viewer. They also correctly show the data that is being calculated by them. We have a few performance issues that need to be worked out, but so far things are going well. Still looking for the end of the month for the next version. Stay tuned for more info!


You don't need a supercomputer to use Positron. Unlike big-name products on the market today, Positron smoothly and easily runs on most high-end consumer systems available today. Designed to be cost-effective and easily accessible to studios of any size, Positron's system requirements deliver an amazingly powerful punch for a very low cost!
