The Scheduler

TitleCardMaker runs all core tasks on schedulable intervals. These can be adjusted by accessing the Scheduler page under Settings > Scheduler (or at the /scheduler URL).

The Scheduler can be in one of two modes: basic (the default) mode, and advanced mode. These two modes can be switched between at any point by clicking the green button at the bottom of the page. All intervals are reset when switching from basic to advanced mode.

Minimum Task Frequency

In both modes, the fastest a single Task can be scheduled is once every 10 minutes.

TCM will also not start a Task while it is already running, so if a given Task takes longer than its assigned frequency, the second run will be skipped.

Basic Mode

While in basic mode, all scheduled Tasks happen on fixed intervals. These intervals are relative to whenever you first launch TCM (i.e. they are not guaranteed to start at the top of the hour). In addition to this, only a subset of the total available Tasks (the most commonly adjusted ones) are displayed.

How often these Tasks occur can be changed by editing the text in the Frequency column of the table. This information can be entered as text, and any combination of "seconds", "minutes", "hours", "days", and "weeks" are supported.

Example Frequency

A frequency string can be as simple as 4 hours, or as complex as 1 day 4 hours 12 minutes 23 seconds.

Advanced Mode

In advanced mode, scheduled Tasks happen according to a "cron" expression. These are expressions which allow for succinctly describing when something can occur, and can be as simple as */30 * * * * - meaning "every 30 minutes" - to as complex as 0 2 * * 1-5 - meaning "at 02:00 AM, Monday through Friday".

Advanced mode also make all Tasks available to be rescheduled.

When Tasks run can be adjusted by editing the cron expression in the Schedule column of the table. A live human-readable description of the expression is given in the next column. There are many online resources to creating cron expressions, but a helpful resource is linked at the bottom of the page.
