![]() ![]() This means we can now use much greater levels of compression to make files smaller, and yet still decode them fast enough to keep up the frame rate. The next generationĬomputers and processors have become cheaper and much more powerful since MPEG-2 was specified in the 1990s. As with MP3 audio files, there are just too many around. It is much more efficient (smaller files) and sounds better than MP2, which is antique – though, sadly, it's still used in Britain's antique DAB radios.įor future-proofing, MPEG-2 files are the next best thing to ISO images, and I don't foresee a time when PCs will be unable to play them. MP2 and AC-3 are the most common, and if you have to pick one of those, choose AC-3. DVDs can have audio tracks in PCM, DTS, MPEG-1 Audio Layer II (MP2), or Dolby Digital (AC-3) format. However, you will probably have lost any extras, including VMG (video manager) files, subtitles, hidden files, adverts and alternative audio formats. ![]() What you have done so far is to rip a couple of DVDs to MPEG-2 (.mpg), so you may have the full original video, but de-interlaced so it is now in the progressive display format used by computer monitors and HD TVs. You could also play the ISO disc image using a software DVD player, including VideoLan's VLC, or rip it using your choice of DVD ripping software. You could burn this copy to another DVD for backup purposes. If you want to preserve everything on a DVD, then the simplest option is to copy the whole disc as an ISO disc image. The 720 x 480 format came from America's NTSC television system and 720 x 576 from Europe's PAL. MPEG-2 was the obvious choice for DVDs as it was already being used for broadcast and cable television. The result is a resolution of 720 x 576 pixels at 25 frames per second, for 50Hz TV sets, or a resolution of 720 x 480 pixels at 29.97 frames per second, for 60Hz TV sets. The video is interlaced for display on ordinary TV sets. The video is held in VOB (Video Object) files. You can also use the dynamic HDR conversion method if you don’t know which LUT to use.Most DVDs store movies in the standard MPEG-2 format (aka H.262) defined by the Motion Pictures Expert Group, though MPEG-1 is also supported. SDR content can be converted to HDR, and HDR to SDR, during restore by selecting a 3D LUT profile. XFile3 is capable of up-converting the resolution during the restore process, so legacy content can be restored towards 1080p or UHD servers, without the need to define your profile. What has always been important for EVS is maintaining the clip metadata and the superslomo frames which you want to use for the next show and which you'd like to keep with your archived media.įor Multicamera recording, XFile3 allows real-time streaming of all camera angles from the server to your storage using an intuitive user interface and including crash-record capabilities and time-based scheduling of these streams.Īs more and more shows are being produced in HDR and with higher resolutions, conversion from and to various standards and formats has become very important. ![]() ![]() This way, EVS solutions can be easily integrated with each other as well as with other 3rd party systems and post-production tools. To facilitate this, EVS has been increasing the codec compatibility. Replay operators or media managers need to be able to not only import last minute content but also to import content coming from other shows. In the last years we have seen the increased need for more tools in XFile. "At EVS we know that XFile has been a great tool in live production environments for years now, as there is always someone walking into the truck that wants to play back clips just seconds later"īrady Jones - Lead EVS LSM-VIA ambassador ![]()
