Error Code:
TimedText-InvalidTickRate (The tick rate is invalid)
Error Message:
The conversion of 1142270000t using the current tick rate defined is invalid. Please add or correct the tick rate (ttp:tickRate) in the source asset.
Definition:
The source asset does define a ttp:tickRate value, but converting one or more tick-format timecodes using that value produces a result that is invalid, for example a timecode that falls implausibly far into the runtime.
This typically means the tick rate defined in the source does not match the rate the timecodes were actually authored against.
Solution:
Review the ttp:tickRate value against how the tick-based timecodes were generated, correct it if needed, and redeliver.
