These containers contain audio/video data encoded in various “codec” formats. Movie files can be in various “container” formats. Some Apple Quicktime MOV files (MOOV Files) can be a problem For example, we might crop the movie, or set a letterbox format. However, if there’s some alternate scaling desired, then sometimes it’s better to bring the movie in ahead-of-time, so that it can be adjusted to suit. This scaling can happen automatically at run-time. So, a movie which was (say) 400×300 pixels in it’s “normal” size, could be scaled to full-screen 1600×1200. The main consideration when scaling is the DA screen height: 1200-pixels. The Data Arena can play almost any resolution, and scale the movie to fit on screen. The movie does not need to be HD format 1920×1080. These movie players are used in the Data Arena. Movie players which use ffmpeg include: mplayer, vlc, and bino-3D. This is great because the FFMPEG library decodes most movie formats. The Data Arena uses FFMPEG as the base library to handle multimedia data. Movie Codecs: mpeg2, mpeg4, h264, quicktime, webm Standard HD Format Movies include: 1920×1080 or 1920×1200 pixels For example, the bacteria visualisation movie is shown in this way. If you’ve been in the Data Arena you might have seen some movies played in this format. The left/right sides of the movies are blended together (approx 100 pixels each side). With the audience standing in the middle of the theatre, each person typically has a clear view to one of the copies. One mode we like to use plays 6 copies of the same movie, replicated around the 360-degree screen. The most common HD formats easily play in the Data Arena. However, the Data Arena can display much more, including 3D Stereoscopic 360-degree Panoramic Movies, and movies designed for Virtual Reality (VR) Head Mounted Displays (HMD). If it’s a standard HD movie (eg TV resolution) then it’s pretty straight-forward. The Data Arena is able to display most of them, with varying amounts of setup. Please contact us to enquire further or to arrange a booking! How to prepare your data for this pipeline This immersive environment is an ideal venue to conduct a client review or launch event for VR movie projects. The screen resolution is “10K” Stereo (10K each eye). The Data Arena displays high-resolution 360-degree 3D-stereoscopic movie content with 16-channel surround sound.
