One second of real life will take four or more seconds to playback. If your camera actually shots 120 fps then there is no need to do anything but adjust the interpretation to 30 fps or less to achieve a 4X slow-motion shot. Twixtor can take a very long time to render and it will not perform miracles on footage that is not suitable to slow down. With other types of footage, you have to do a ton of customizing with the controls. Also, you should be aware that if your material has 3:2 pulldown you should remove it beforehand. RE:Vision Effects, acclaimed effects plug-in industry leader and makers of Academy Award winning software, announces the initial release of their Twixtor plug-in for Vegas Pro by Sony Creative Software. As such, you will need to remove duplicated frames before the application of Twixtor. With the right kind of footage, this works amazingly well. Duplicated Frames: Twixtor does not provide automatic duplicated frame detection support. Twixtor makes a good estimation of the movement of the detail areas (luminance) and predicts where things in the scene will move then creates new frames with these estimates. If you put 120 fps footage interpreted at 30 fps in a comp that has a frame rate that is 24, or 23.976, or 60, then some frames will be blended, dropped, or duplicated. If you put your footage in a 30 fps comp or 30 fps sequence you will see every frame. If you shoot at 120 fps and change the interpretation to 30fps in AE then, no matter what the frame rate of the composition, one second of recorded action will take, do the math, 120 / 30, 4 seconds to playback. This happens because NLE's and compositing and VFX apps like AE try and maintain real-time sync which is critical for sync sound and a bunch of other things. If you shoot 120fps footage and load that footage in After Effects or Premiere Pro and put that footage in a 24, or even a 12 fps composition then one second of action captured by the camera will still take one second to playback, you will just be skipping frames. If your camera frame rate matches your playback frame rate then one second of the action you record will take one second to playback. Games can run at much higher frame rates but games really have very little to do with movies or video. Digital projection is also sometimes running at 48 fps. Occasionally, and usually a waste of bandwidth the playback speed will be 59.97 or 60 fps. That is usually 23.976, 24, 25(in PAL countries) and 29.97. Twixtor changes speeds and frame rates of clips by a process of interpolation and warping of frames from the original sequence. The first consideration is your playback frame rate. Throw in interlacing, comp frame rates, and file interpretation and it's really easy to get confused. Most folks that have not shot with a real motion picture camera don't understand frame rates and slow motion. Twixtor is a plug-in program for the After Effects software that allows you to create slow-motion effects from any video clip by adjusting the settings of.
