Frame Generation
Motion interpolation, motion-compensated frame interpolation (MCFI), or frame generation is a form of video processing in which intermediate film, video or animation frames are synthesized between existing ones by means of interpolation, in an attempt to make animation more fluid, to compensate for display motion blur, and for fake slow motion effects. Hardware applications Devices Motion interpolation is a common, optional feature of various modern video devices such as HDTVs and AV receivers, aimed at increasing perceived framerate or alleviating display motion blur, a common problem on LCD flat-panel displays. Difference from display framerate A display's output refresh rate, input drive signal framerate, and original content framerate, are not always equivalent. In other words, a display capable of or operating at a high framerate does not necessarily mean that it can or must perform motion interpolation. For example, a TV running at 120 Hz and displaying 24 FPS con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interframe Motion Interpolation
An inter frame is a frame in a video compression stream which is expressed in terms of one or more neighboring frames. The "inter" part of the term refers to the use of ''Inter frame prediction''. This kind of prediction tries to take advantage from temporal redundancy between neighboring frames enabling higher compression rates. Inter frame prediction An inter coded frame is divided into blocks known as macroblocks. After that, instead of directly encoding the raw pixel values for each block, the encoder will try to find a block similar to the one it is encoding on a previously encoded frame, referred to as a Reference frame (video), reference frame. This process is done by a Block-matching algorithm, block matching algorithm. If the encoder succeeds on its search, the block could be encoded by a vector, known as motion vector, which points to the position of the matching block at the reference frame. The process of motion vector determination is called motion estimation. In most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strobing Backlight
In modern displays, motion blur is an unwanted artifact caused primarily by: # Retinal blur resulting from your eyes ''continuously'' tracking ''discrete'' movement. While your eyes move, the object you're tracking remains stationary throughout each frame, causing it to "smear". This does not happen in real life where both move continuously. # Slow pixel response times, which lead to visible ghosting or smearing. The faster the motion, the more pronounced the effect is. Cause Displays work by rapidly showing frames, each one slightly different from the previous, thereby creating the illusion of movement. Let's take a normal computer monitor with a resolution of 1920×1080 and a refreshrate of 60 Hz. If an object were to move across the display in 2 seconds, there would be 60×2 = 120 "steps", each one translated by 1920÷120 = 16 pixels. Your eyes, however, would not start and stop, over and over again to track the object, quickly moving the fovea to the "new" position ...

Plug-in (computing)
In computing, a plug-in (also spelled plugin) or add-in (also addin, add-on, or addon) is a software component that extends the functionality of an existing software system without requiring the system to be software build, re-built. A plug-in software feature, feature is one way that a system can be customizable. Applications support plug-ins for a variety of reasons including: * Enable third-party developers to extend an application * Support easily adding new features * Reduce the size of an application by not loading unused features * Separate source code from an application because of incompatible software licenses Examples Examples of plug-in use for various categories of applications: * Digital audio workstations and audio editing software use audio plug-ins to generate, process or analyze sound. Ardour (software), Ardour, Audacity (audio editor), Audacity, Cubase, FL Studio, Logic Pro, Logic Pro X and Pro Tools are examples of such systems. * Email clients use plug-i ...

Video Editing Software
Video editing software or a video editor is software used for performing the post-production video editing of digital video sequences on a non-linear editing system (NLE). It has replaced traditional flatbed celluloid film editing tools and analog video tape editing machines. Video editing software serves a lot of purposes, such as filmmaking, audio commentary, and general editing of video content. In NLE software, the user manipulates sections of video, images, and audio on a sequence. These clips can be trimmed, cut, and manipulated in many different ways. When editing is finished, the user exports the sequence as a video file. Components Timeline NLE software is typically based on a timeline interface where sections moving image video recordings, known as clips, are laid out in sequence and played back. The NLE offers a range of tools for trimming, splicing, cutting, and arranging clips across the timeline. Another kind of clip is a text clip, used to add text to a video ...

Trimension
Trimension is a framerate enhancement software by Philips for video, primarily DVD. The software utilizes both picture and stream information to render new frames between the original frames of video (tweening), thus increasing the framerate and enhancing the smoothness of motion. Currently, Trimension is capable of enhancing frame rate from 24 to 48 (for 60 Hz displays) or 72 frames per second. The motion interpolation produced by Trimension is not entirely natural, but can be pleasing in many respects. The software has been criticized for artificial look and has been said to make film seem like video, and potentially to degrade the movie-watching experience. There is also a slight cropping of the video to allow for good edges of the smoothed picture. Framerate enhancement can provide an interesting benefit if it is performed after upscaling. If the picture is scaled to a high-definition resolution and then tweened, the tweened frames will have motion that exists in th ...
