Version 2.0.4 | January 24, 2003

  • Added G4 support for Mac OS versions. Twixtor now runs significantly faster on G4 machines
  • Twixtor frame rate conversion now works from within combustion 2.1 and Commotion 3.1 and later.
  • Fixed a bug that caused Twixtor to not add motion blur when speeding up footage in reverse

Version 2.0.3 | April 25, 2002

  • Fixed a bug that caused improper inbetweening when using multiple frame rates. This fix should affect users of Twixtor from within After Effects, using the frame rate conversion feature of Twixtor.

Version 2.0.2

  • Fixed a bug that caused unnecessary stuttering in certain cases when keyframing the Frame parameter.
  • Organized the buttons for combustion
  • into related groups (and now the last set of buttons spills on to a second page).

Version 2.0.1

  • Fixed a bug that corrects the following problem: when specifying output interlaced video, the fields were reversed (that is, when specifying Lower Field First, Twixtor generated upper field first video, and vice-versa).
  • Fixed a bug in which output with fields did not work with 16-bit per channel projects (Pro version only).

Version 2.0

    Currently only the After Effects version (for After Effects, Final Cut Pro, Premiere 6.0, Combustion and Commotion) has been updated to version 2.0.

  • We've renamed and replaced some of the options to make things clearer:
    • o Multiple Layers of Motion? has been renamed: Crossing Objects? (Conflicting motion?). This was done because we added the notion of foreground and background layers, and we didn't want to reuse the word "layer."
    o The frame interpolation mode Multi-Frequency has been eliminated and Motion Weighted Blend has been added. The Multi-Frequency mode was not very useful. From the 1.5 manual describing Motion Weighted Blend: When a new frame is created from existing frames it is often the case that some softening is introduced. This softening can more or less strong (depending on how far away in time the new frame is located from existing frames in the original sequence. This can result in a pulsing of what appears to be the Twixtored sequence coming in and out of focus. The Motion Weighted Blend option attempts to reduce this pulsing.
    o Time Warp Layer has been renamed Color Source. This is because you can now have color source and a tracking source that are different clips (see manual) so, in a sense, both the Color Source and Alt Motion Source (alternate tracking source) are part of the time warping input information.
  • We've added quite a few features:
    • o Alt Motion Source: Allows you to specify a different clip for tracking than the one used for color. (Previously, the same clip was always used for both tracking and color ).Of course, Twixtor assumes these two sequences line up in time.
    o Plenty Memory? (Cache last motion?): When slowing down footage, computation can often be sped up by keeping the last motion estimation vectors and reusing them. Please read the manual for approximate amount of memory needed and a few "gotchas."
    o Motion Sensitivity: Prior to version 2.0 you really had no choice to limit the amount of motion calculated for any motion estimation quality. The newly added Motion Sensitivity option now allows you to limit how much pixels can move once a particular motion vector quality is chosen. This can help eliminate the "gloop" in creating new frames that is seen when objects pass over each other in the imagery.
    o Finally, in Twixtor Pro, we allow you to specify (via a matte), a foreground layer that is separate from the background layer. The two layers are tracked, interpolated and warped separately. Twixtor uses proprietary filling and tracking techniques when working on the background layer, even when it is obscured by the foreground! Note: applying earlier versions of Twixtor to 2 layers (the foreground and background) and then combining them does not produce the same results, because in Twixtor Pro we figure out the motion for the portion of the background layer that is covered by the foreground later, an important part in reconstructing the background when the foreground moves in front of it.
    o We've optimized Twixtor so that it doesn't perform motion estimation when it doesn't need to.
  • Because we've added new options in version 2.0:
    • o You'll see that we've renamed the plugin, and that it will show up in the applications as "ReelSmart Twixtor 2.x." That way, your old projects will still run and load (using pre-2.0 Twixtor).
