It’s basically an executable file designed to resemble, in its style, a DVD or Blu-ray. Don’t worry, I intend to make sure these files are safe for viewing. In fact, if I didn’t believe the video files generated in Godot Game Engine were safe, I wouldn’t have even proposed it in the first place.
As for the EDL potential, that’s one of the things I’ll look into after I prove the concept. Also, I’m thinking of standardizing the format, so that people will have a better understanding of what GVS modules are supposed to be. One thing I’m researching is the resolution of film, so I can work out standard resolutions for each original medium (e.g. 35mm Academy format, 5/70 Todd-AO, 15/70 IMAX, 16mm, even certain videotape stocks) and ensure that every film will be made available in its original theoretical resolution. The sooner standards, including the code, video, audio, subtitles, and export format, are reached for open home media, the better.
