Accepted File Types & Encoding Tips
File types accepted as-is:
Still: .jpg, .png (both in RGB Color Profile)
Video: h.264 .mp4 (10 Mbps constant bit rate – cbr)
All other formats must be reformatted to the above specs and resolutions.
Profile and Level
Most encoders let you choose something called a profile and a level. These are pre-set categories that specify limitations on resolution, compression and bitrate.
General recommendations (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
Pixel Aspect: 1:1 (square).
Fields: Progressive (ie: not interlaced).
For H.264 encoding, use CAVLC (not CABAC) for best software decode performance.
Key Frames: Every 1 sec (30 frames).
Frame Rate: 30 fps
60 fps possible with high performance PC such as the ZI.1XRG
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.
Most Zero-In display solutions operate at 60 fps.
Additional Sync Guidelines
Content should not have audio, all audio tracks and component must be removed prior to uploading to Scala.
