Video Quality Studio 0.4 RC1 2005-02-26 17:46:44 Hello,Version 0.4 RC1 of Video Quality Studio was released a couple of days ago. Download here Changelog:Objective: * Reworked VFW and DirectShow decoders. YUV (YUY2/YV12) is preferred over RGB and is converted internally to 4:4:4. This should minimise calculations and thus enhance performance greatly. * Single precision floating-point numbers are now used instead of double precision as they provide a better balance between accuracy and speed. * Added Structural Similarity (SSIM) Index metric. Note that it is a basic implementation and not complete with motion estimation! * PSNR was optimised for speed and as always validated with Matlab. * Internally re-worked GUI which should run more smoothly now. * Added XML batch file support. For format see this example. * Average and Standard Deviation values are written to the output. * Misc changes. * Known issue: Decoding of HuffYV12 (Ffdshow) videos produces bogus results when using VFW decoder!Subjective: * Transition between clips is smooth and does not display a white window. * Additional error checking * Added option to shuffle playlist * Fixed bug that allows to restart the test if you abort it * Easier to use GUI. Complete internal remake of the GUI, this should work more smoothly. * Added option to allow different length videos. Defaults to disabled! * Improved DirectShow support, fixes issues with broken/incomplete source filters, fixes issues with overlay with some decoders. * Improved Avisynth support. * You can select a range from reference videos instead of viewing the whole video. * Results are shown after the test ends and you can save them in text or comma-separated formats. * Tests: Save to / Load from XML files functionality. * Playback is stopped when the test is aborted. * Performing a test twice does not cause a crash. * Aborting the test before playback does not cause a crash. * Option to disable topmost style of video window. * Other internal changes.
