GraphStudioNext is a DirectShow graph editor. It's an open source alternative to Microsoft Graph Edit in the Windows SDK with many additional features.
GraphStudioNext is a fork of RadScorpion's GraphStudio. Because development had stopped on the really useful tool GraphStudio, I started this fork. I use this application every day and I needed some new features to support my workflows and wanted to fix some really annoying bugs.
You're welcome to submit bugs and feature requests or just comment whether you like or hate the application here.
Thanks to the following for supporting the development of GraphStudioNext:
- ROOT6 Technology Creators of workflow automation software.
Release: graphstudionext.exe (.pdb)
Debug: graphstudionext.exe (.pdb)
Release: graphstudionext64.exe (.pdb)
Debug: graphstudionext64.exe (.pdb)

New Features:
- Create stream buffer recordings from Stream Buffer Sink filter property page issue #302
- Display IPin::QueryInternalConnections result in Pin PropertyPage issue #300
- Connect newly created filter to previously selected filter for faster graph building issue #265
- New option to reserve memory below 2GB/4GB for testing 32bit LargeAddressAware filters and 64bit filters for pointer truncation bugs issue #298
- Mediainfo information display for files created by file writing filters (similar to source file filters) issue #278
- Save text/graph information with graph and tweaks to text information issue #277
- Show current sync source in status bar
- Include frames per second in video media type details issue #295
- Implement loading from ipersistpropertybag option when loading GRFX files issue #284
- Added count*average column to statistics windows issue #270
- Integration with DirectShowSpy property frame helper in remote graph form issue #264
- Display filter merit as SDK constant (as opposed to numeric value)
Bug Fixes:
- Fixed bug in sync source selection in new graphs issue #291
- EVR renderer is no longer closed and recreated when graph is refereshed issue #293
- Fix to Analyzer Filter property page issue #289
- Filters having no valid CLSID are showing invalid tool tip with text from another filter issue #288
- Analzyer writer filter returns current position from IStream::Seek issue #281
- Fixed wrong loading of current sync source in GRF and GRFX files issue #268
- 32bit version running on 64bit OS no longer silently ignores exceptions that happen from user mode callbacks (e.g. key press handlers) issue #269
- Better robustness against filters that delete rather than Release() pins issue #115
- Better property page positioning issue #213
New Features:
- Navigate around filter graph using keyboard. Arrow keys navigate between filters, control-arrow navigates between pins, shift key extends the selection. Newly created filters are connected to the currently selected output pin. Escape key to clear filter and pin selection. Shift F10 or menu key for context menu. Enter or Alt Enter for properties. Delete or Backspace to delete filter(s) or disconnect pin(s). Shift Delete or Backspace to disconnect filter(s). (issue #217, #issue 252, issue #254)
- Connect pin offers popup menu of available target pins to connect to. If selected pin already connected, reconnect with the same media type (or use intelligent or choose media type modes if enabled). If two filters are selected, connect the filters together via the first available pins. (issue #222, issue #249)
- XML files now saved under new .grfx extension. .grfx file extension is registered with Windows (issue #152)
- Preview and filter DbgLog file output in property page (NB DbgLog works in debug filter builds ONLY). Also configure registry settings for DbgLog. (issue #61)
- Better support for creating filters directly from DLLs instead of CoCreateInstance. Scan for CLSIDs implemented by DLL, create the filter from the same DLL when graph is saved to .grfx file and reloaded (impossible to support this for .grf files though). DLLs appear on the File menu as recently used files (but don't clear the existing graph when 'opened'). Property pages are created directly from filters DLL class factory with fallback to creating via CoCreateInstance. Can be used to run two different versions of the same filter side by side in a single graph. (issue #31)
