12/25/2023 0 Comments Settings for twixtorThe Frame Number slider is only shown when Time Remap Mode is set to Frame Number. Time Remap Mode:Frame Number If Frame Number is chosen, then Twixtor knows you'll be keyframing your time resequencing by exact frame numbers. In general, if you want to play the whole clip backwards (and slow it down as well), we recommend you reverse the clip first using MCs tools, and then apply Twixtor to make the speed change. If you play the clip at 100% for a while, then put in a 30% keyframe (or other negative value) at the place where you want to start playing backward you will see proper results. That's why you will not see a result with a negative speed as the first keyframe. If you are at the beginning of the clip and you tell the machine (Twixtor in this case) to start playing backward, then there's nothing before the clip starting position to play. Note on negative speed: A Speed% of -100.00 does not simply flip the original sequence so that it plays backwards starting at frame 0. Note that you can type in a higher value even though the slider shows a smaller range than the valid range. However, the initial slider display in most host applications will be -1000% to +1000% (-10 to +10 original rate). Valid Speed% settings are from -10,000% to +10,000 (that is -100 to +100 times original rate). ![]() You may ask "I know that I want to change the duration of the clip by a certain amount, how do I figure out how to set the Speed setting?" In general, if you have a constant factor for a duration change, set Speed% to: 100 / (duration change)įor 2X duration change, set Speed% = 100/2 = 50% For a 0.5 duration change (speed up), set Speed% = 100/0.5 = 200% ![]() A value of 50 (percent) tells Twixtor to play the clip 1/2 as fast as the original, a value of 300 tells Twixtor to play the original clip at 3 times its normal rate. To obtain the speed of the clip, Twixtor gets the value from the Speed% slider. The Speed% slider is only shown when Time Remap Mode is set to Speed. Time Remap Mode: Speed When Speed is chosen as the Time Remap Mode, then you can set (and animate) the speed of the input clip. How do I retime my clip? Time Remap Mode: This menu has 2 options for the retiming method: This setting is particularly useful when setting Twixtor's Mark Segments setting.Ĭhanging sequence timing.Okay, now here's the meat of the plugin. Display:Source: This setting displays the original color source with no retiming done. Display:Twixtored Output: This setting displays the final Twixtor time-remapped result 2. Usage of TwixtorWe now describe the basic Twixtor usage. Later in this manual we will discuss how and where you should apply Twixtor, so keep reading! Then to apply Twixtor to a clip in the timeline, select it in the Effects Browser and then follow these instructions from the FCP manual (in this case the effect in question is Twixtor). Then youll see Twixtor in the Video Effects, under the REVisionEffects category. Locating TwixtorTo locate Twixtor, first show the Effects Browser, which can be done by clicking the Effects button in the toolbar. Twixtor can handle different frame rates for the source clip and the output by using certain workarounds. This is useful to know when trying to figure out why Twixtor doesn't apply proper processing to frames from a 3:2 pulldown sequence or animation done on "2"s, etc. If there is no motion between two frames then there will be no inbetweening. If you have 3:2 pulldown in your source clip, you will want to remove 3:2 pulldown before processing with Twixtor. Twixtor works most intuitively on both progressive material and interlaced material. Ability to mark cut points so that material with edits can be retimed or transcoded without breaking the material into pieces firstįCP X version of TwixtorTwixtor is an FxPlug plugin that works with FCP X (see website for exact versions)The Twixtor plug-in is installed into /Library/Plug-Ins/FxPlug Twixtor Features:Ĭalculation of motion vectors at each pixel Warping and interpolation of frames to "time warp" input footage Stretching of a sequence using a single speed scaling parameter Keyframeable retiming for complete control on a frame-by-frame basis. employing RE:Vision's proprietary tracking technology that calculates motion for each individual pixel. In order to achieve its unparalleled image quality, Twixtor synthesizes unique new frames by warping and interpolating frames of the original sequence. ![]() ![]() Twixtor enables you to "time warp" your image sequences with visually stunning results. What is Twixtor?Twixtor intelligently slows down and speeds up your image sequences.
