Hi, i have various devices which i use to watch films. To avoid transcoding i would like to store optimized versions for iPad and iPhone. When i try to create a optimized version it fails all the time. Can i create optimized version by my self? How are the naming conventions? I would like to have from a film 2 versions, one with 1920_1080 resolution and another version with 1280_720. Both have the extension _.mp4. The only difference is the resolution, because 1920_1080 works on my tv’s, while 1280\*720 works on my iPad and AppleTV. ---

While definitely not the ideal way, you could simply name your movie files the same and then add additional information in brackets after the year. For Example: Dr. Horrible’s Sing-Along Blog (2008) [1080p].mp4 Dr. Horrible’s Sing-Along Blog (2008) [1080p Optimized].mp4 Dr. Horrible’s Sing-Along Blog (2008) [720p Optimized].mp4 With that the server should automatically combine the 3 files into 1 movie entry with blue circle in the corner with the number of movies in the entry (in this case a blue circle with a 3). Now some apps will prompt you to select a version when you hit play, other apps if they have specific requirements should be trying to use a file that will direct play over others that would require transcoding. ---
