    • Iron Man.Use of text - Interactive Menu.Brief Description.•Characters are going across the screen. There is colourful imagery used as it’s attracting a childrenaudience. Layers used (compositing video).Techniques Used•Animation, visual effects, computer generated animation, graphics and animation used as the filmis live action and computer animated. Dark colours like dark red and grey are used, I think this isbecause obviously they are aiming more for a male audience with this interactive menu so they arechoosing colours that appeal to the male audience, if they were to use colours such as pink and lightblue that are classed as more girly colours then people wouldnt perceive the interactive menu in theway they want.Advanced Techniques•The images don’t look very sharp to me, but this is most likely as we are watching this off YouTube.They would have to be of a professional standard so it doesnt look amateur to the audience as thatcould make them think less of it and not take as much notice. Quite dark music in the background,this could be to make the audience aware of what type of film it is. From listening to the music youget the feeling that its quite gloomy and action packed.Technical Comments•480 pixels Display aspect ratio: 16/9 Frame rate: 29.970 fps (23.976 Internal) standard.Pixels:In digital imaging, a picture or pel (picture element) is a physical point in a raster image or thesmallest addressable element in a display device; so it is the smallest controllable element of apicture represented on the screen. The address of a pixel corresponds to its physical coordinates.Resolution:The aspect ratio of a screen or image describes the proportional relationship between its width andits height.Frame rate:Frame rate (also known as frame frequency) is the frequency (rate) at which an imaging deviceproduces unique consecutive images called frames. The term applies equally well to film and videocameras, computer graphics and motion capture systems. Frame rate is most often expressed inframes per second (fps) and is also expressed in progressive scan monitors as hertz (Hz).Video formats:A video format defines the way in which video is stored and recorded. It normally specifies:
    • Codec/compressorFrame rateFrame sizeFrame aspect ratioPixel aspect ratioScanning method (interlaced or progressive)Common formats are DV/HDV and AVCHD.Compression:Codec is short for coder – decoder and describes the method in which video data is encoded into afile decoded when the file is played back.Transcoding is the process of converting from one process to another.Codecs can be lossless which means that they don’t throw away any data, or lossy which means thatdata is lost during encoding. Lossless codecs are higher quality than lossy codecs, but produce largerfiles.
