When you animate,
Maya Creative needs to keep track of the timing of keys. Maya internally converts each frame's time value to a 64-bit whole number representation, which is called a
tick.
Ticks
Ticks are the smallest increment of time in
Maya Creative and each represents 1/ 141,120,000 of a second. This means that
Maya Creative counts 141,120,000 ticks per second (tps), at a rate of 24 frames per second (fps) – that's 5,880,000 ticks per frame (tpf).
Even though
Maya Creative always uses the same number of ticks per second, the number of ticks per frame varies depending on which playback speed you choose. To calculate how many ticks per frame
Maya Creative uses at your selected playback speed, divide the tps (141,120,000) by the playback speed you're using.
For example, at 15 fps, you have 9,408,000 tpf (141,120,000/15).
When you use this formula on non-integer (or round-number) frame rate, for example 29.97 fps, you won't always get integers (for example, a whole number, like 5) as a result. This is because
Maya Creative cannot represent every fractional frame rate (such as 25.55). Any time
Maya Creative needs to approximate a tick value, the time is displayed with an asterisk *.
However, the
Maya Creative tick is so small (1/141,120,000th of a second) that it is extremely precise even when you use fractional frame rates (such as 24.976 or 29.97 fps).
Note: To avoid issues with numerical over or underflow, ticks are forced to lie in the range of 64-bit (signed) integers.
Time precision and binary file formats
In order to be backward-compatible, we recommend that you save your scenes as
Maya Creative ASCII (.ma) files.
