720P Video Requirements Specification for Ingest
V 1.1 October 16, 2020
These are the current recommended specifications for uploading video into CORE. Video not matching these specs may take longer to be playable or may have difficulty processing.
Processing times for files not in the optimal specification will be processed at a rate of approximately 3-4x real-time.
This document will provide the current recommended specifications, descriptions of each parameter, and will give a sample encoding example to use.

Description
Video Resolution - Optimized Video Resolution setting for CORE at 1280 x 720.
Data Rate - Optimized Data Rate at 3300 kb/s or 3.3 Mb/s. If the Data Rate is higher than the spec mentioned will result in longer delays for the video to be playable on CORE.
Frame Rate - Frames Rates will be the same as source. It is preferred to be 24 frames per second.
Encoding Profile - Baseline - The Baseline profile is the simplest profile, and supported by most decoders.
Pixel Aspect Ratio - (often abbreviated PAR) is a mathematical ratio that describes how the width of a pixel in a digital image compares to the height of that pixel. CORE requires the square pixels type.
Color Space ITU - Color spaces are mathematical models describing the way colours can be represented. CORE specs recommend Rec. 709 or sRGB LUT.
Compression Type - CORE uses the H.264 compression type. H.264 is the well-known video compression standard for high-definition digital video (Also known as MPEG-4 Part 10 or Advanced Video Coding (MPEG-4 AVC).
Container Format (Wrapper) - CORE’s recommended container format is .MOV (quicktime).A container format is a type of file format that contains various types of data compressed by standardized codecs.
Encoding Audio Format - CORE’s recommended Encoding Audio Format is AAC. An encoding Audio format is a content representation format for storage or transmission of digital audio.
Audio Bit Rate - CORE’s recommended Audio Bit Rate is 192 kbit/s or below.
