The blocks that make up the number 4 seem morebolder and stand out more than everything else in the clip.Technical comments:Video Format, Screen Ratio, Resolution,Frame rate, CompressionMost idents are created from 720p or 1080i sourced captures. The codes that idents use are1:8 and the resolution is standard.
  2. 2. Salford City CollegeEccles CentreCreative Media Production2GlossaryMotion graphics - Graphics that use video footage and/or animation technology to create the illusion of motion or rotation, graphics areusually combined with audio for use in multimedia projects.Compositing video - When there are several different clips of video are layered over one another to create a single image.Interactive Menus – DVD Interface or Interactive Menus on a web pageIdent – The ‘call sign’ of a channel or production company to identify themselves on screen, usually shown before a programme.Animated Captions – Animated Graphics layered over an image / videoWeb Banners – A form of web advertising that is embedded into a web page. They are used to attract a viewer to their website. A WebBanner usually a mix of motion graphics and videoVideo Format - 3 Main Formats HD, PAL, NTSC. HD is the highest resolution (720 or 1080 vertical lines in the image). PAL is the UKStandard definition image (576 vertical lines). NTSC is the US Standard definition image (480 vertical lines). Now in thedigital age we now look at video format in terms of pixels (i.e. High definition 1080; 1920 x 1080 or 2,073,600 pixels)Screen ratio – Standard TV ratio is 4:3; this means that for every 4 units wide it is 3 units high. It is likely that the screen ratio will beWidescreen (16:9) in a cinematic sequence.Resolution – The amount of detail in an image or signal, such as Standard TV Definition and High Definition. See Video Format.Frame Rate - The number of video or film frames displayed each second (frames per second; fps). PAL frame (standard UK TV) is 25fps, NTSC (standard US TV) is 30 fps, film is 24 fps. This means as NTSC updates more regularly there is less strobing(jerkiness).Compression – The use of Codecs (WMV, DivX) to reduce the file size of a video by a variety of methods. This sometimes means a loss inimage quality (a “lossy”). Codecs are found in Video Cameras, DVD players / recorders, Editing Packages, Video uploadsites)
