The following video specifications can be used as a guideline in order to provide video files that will allow the MediaStore platform to generate optimal-quality online screening proxies:

  • Video
    • Codec: MPEG-4 Layer 10 (H.264/AVC)
    • Resolution: 1920 x 1080 pixels (HD) or 3840 x 2160 pixels (4K)
    • Framerate: 25p (PAL) or 24p / 30p (NTSC)
    • Bitrate: 5 to 15 Mbit/s (HD) or 10 to 30 Mbit/s (4K) (for optimal results, use the suggested maximum bitrate based on resolution)
    • Use 2-pass encoding for optimal results
  • Audio
    • Codec: AAC
    • Bitrate: 256 kbit/s
    • Sample rate: 48 kHz

Of course, MediaStore will generally accept most video formats and qualities. Be aware though, that the platform cannot enhance inferior source material, and will compress higher-spec files down to an ideal streaming quality. In any case, your originally uploaded video file will be retained as a downloadable asset, and any platform-side compression will only serve to provide a screening-quality proxy file.
