  • Adds direct Scratch GPU memory support for faster processing in Scratch 8.6.947 and later

Version 6.0 | March 21, 2014

  • Initial 6.0 release with GPU acceleration.

Version 5.2.2 | January 4, 2013

Version 5.2.1 | November 1, 2011

  • Fixed a bug where red frames were displayed instead of the last frame found in the media or video event. Documentation and tutorials updated appropriately.

Version 5.2 | June 30, 2011

  • Initial Release
  • Known bug in Vegas Pro 10.0d (fixed in 10.0e): deleting an event with Twixtor can cause Vegas Pro 10.0d to crash. The solution is after scrubbing the timeline, wait several seconds before deleting the event with Twixtor (essentially you need to wait until Vegas finishes rendering the 8 or more frame it may be calculating in the background after you move the current time pointer).
  • Similarly, if you scrub within the timeline or move the current time pointer, wait several seconds before exiting Vegas Pro or it may crash. We are working with Sony and hope to have this fixed in an upcoming release of Vegas Pro.
