ThumbGenie 1.2 Now Supports Bilinear Image Resampling (improved scaling in non-geek speak)

One of the things that’s sort of sucked about ThumbGenie has been the quality of scaled thumbnails. The 640×360 image below was generated from a 960×540 video frame. Notice the edge degradation (jaggies) and poorly rendered text that results from the nearest neighbor scaling.

ThumbGenie 1.2 makes some very noticeable improvements to the quality of scaled thumbnails, as seen below, by doing bilinear resampling using a Pixel Bender kernel.

The update also includes some bug fixes:

  • Fixed bug that caused aspect ratio to be incorrectly displayed in the output dimensions field when “retain” was checked and video of a different aspect ratio was loaded. Because this bug has been fixed the “R” reset button has been removed from the UI.
  • FIxed bug that prevented text from being pasted into the embed code window when the the keyboard shortcut for paste was used.

If you’re dying to get your hands on ThumbGenie, or have no idea what it is, check out its home page for an overview and some helpful videos:

    Hello,
    Can you also post the pixelbender filter please :)
    Something like that could be usefull for the flash comunity.
    Thanks

    What framerates are you getting in pixel bender CPU mode?
    also source code would be very great to have. It would definitely help the flash community.
