Content Deadlines, Configuration Updates, and Changes

Trison requests 3 weeks notice before installation date for final on-screen content direction, including all linked urls and screen ordering for live testing.

If there are any design changes that require a change order, Trison will provide best effort to accommodate the requested installation schedule where any delays due to parts ordering, configuration, shipping will be communicated to the construction/installation teams. Please provide any design changes to Trison ASAP to mitigate any scheduling delays.

Updates to the installation schedule will be contingent upon supply chain, configuration, and shipping timelines and in accordance with the site location. Any additional costs related to parts changes, restocking fees, reconfiguration, and/or expedited shipping will be communicated back to the client construction/installation teams for approval.

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.

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).

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

60 fps possible with high performance PC such as the ZI.1XRG

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.
