Check a Video Coding Format

• Check supported video formats
• FFmpeg is recommended to convert files and check formats. https://www.ffmpeg.org/
  • Bitrate General recommendations (WMV/H.264):
    • SD 480p: 4-8 Mbps
    • HD 720p: 8-12 Mbps
    • HD 1080p: 16-20 Mbps
    • 4K 2160p: 30-40 Mpbs
  • Profile and Level General recommendations (WMV/H.264):
    • SD 480p: Main Profile, Level 3.1
    • HD 720p: Main Profile, Level 3.2
    • HD 1080p: High Profile, Level 4.1
    • 4K 2160p: High Profile, Level 5.1
    • Use Main Profile, High Level for HD MPEG 2.
  • Additional Encoding Tips
    • Pixel Aspect: 1:1 (square).
    • Fields: Progressive (ie: not interlaced).
    • Closed GOP.
    • For H.264 encoding, use CAVLC (not CABAC) for best software decode performance.
    • Key Frames: Every 1 sec (30 frames).
    • Frame Rate: 30 fps NTSC, 25fps PAL.
    • 29.97 fps is acceptable for NTSC.
    • 60 fps possible with high performance PC.
    • Audio: AAC 192-224 Kbps CBR, 44KHz or no audio at all if the screens will not have sound or no audio was in the source.
    • If the encoded frame rate isn’t a match or multiple of the screen refresh rate, you may see stuttering on some videos, especially on horizontal motion. For example, content encoded 24 fps may stutter on screens that operate at 50 or 60 frames per second. This can be avoided by re-encoding the video with a frame rate that is equal or an even multiple of the screen. For example, 30 fps for a 60 fps screen.
