Use this accurate free stopwatch to time the events you wish to animate. Begin by typing in the framerate you desire in the F.P.S. (Frames Per Second) box. Once this is done you can time any action (like the bouncing of a ball) using the Start/Stop button. The result will display how many Seconds the action took and the number of Frames that you must use to animate the timed action at the selected frame-rate. To start over, be sure to push re-set to Zero-out.

Even though this is maybe convenient as an online animation aid; it is better that you have a Stopwatch in your hand to time actions, movements & motion. You convert elapsed minutes into total seconds, then multiply that by Frame Per Second rate, either, 24Fps, 25Fps, or 30Fps (video in USA). Or you can make FPS to Decimal breakdown of frames, reference Charts.

Real easy one: Minutes to Frames

First convert minutes to seconds, example: 2 minutes x 60 seconds = 120 seconds, then ....
For 24-fps, 120 seconds x 24 = 2880 Frames (= 2 minutes of time)
For 30-fps, 120 seconds x 30 = 3600 Frames (= 2 minutes of time)
If you want to know fractional-decimal parts that is less than One second, then use our handy-dandy Frames to Decimal chart which you will see, as you scroll down.

Converting FPS to other FPS

Converting 24-fps to 30-fps, example: 12 frames (@ 24-fps) to 30-fps rate ....
12 frames X 1.25 = 15 frames, which is 1/2 second of time @ 30-fps

Converting 30-fps to 24-fps, example: 15 frames (@ 30-fps) to 24-fps rate ....
15 frames X .80 = 12 frames, which is 1/2 second @ 24-fps

Converting 25-fps to 30-fps, example: 13 frames (@ 25-fps) to 30-fps rate ....
13 frames X 1.2 = 15.6 frames or about 16 frames (rounded-off), which is close to 1/2 second @ 30-fps

Every Animator needs to use a STOP-WATCH

Frames TO Decimal Fractions of up to One Second when using STOP-WATCH. Let's say your digital Stop-watch says, 1.34 seconds. We know that 1 second is either 24 frames or 30 frames (whichever frame rate you are using). So for the .34, you would look at 24 FPS chart below and we can see that .34 is close to .33 = 8 frames, and so, 1.34 seconds would be about 24 frames + 8 frames = Total 32 frames @ 24-fps. In the 30 FPS chart, you see that .34 is close to .33 = 10 frames, and so, 1.34 seconds would be about 30 frames + 10 frames = Total 40 frames @ 30-fps.

I did not do a 25 FPS chart. Easy to calculate and make. Example: 5 frames ÷ 25-fps = .20
You do that formula for each frame ( 1, 2, 3, 4, 5, 6..... ), up to 25 frames ( = 1 second). Round off to TWO decimal places, as you see in below charts.

The 'Metronome': A valuable tool for Animators

Converting Metronome Beat Numbers to Number of Frames @ 24-fps, example: We want to know the number of frames at the Metronome Beat "# 120" setting ....
A) Establish the constant divisor factor, 60 seconds x 24-fps = 1440 (frames)
B) 1440 ÷ 120 (metronome beat #) = 12 Frames @ 120 Beat #
When you set the Metronome to #120, the time-space between the tick sounds is exactly 12 frames (1/2 second), which for example, @ 12 frames per step/stride, can ----be the pace of a brisk animated walk. You can audibly hear the timing which helps ----you learn, feel and sense the timing, quicker.

Converting Metronome Beat Numbers to Number of Frames @ 30-fps, example: We want to know the number of frames at the Metronome Beat "# 120" setting ....
A) Establish the constant devisor factor, 60 seconds x 30-fps = 1800 (frames)
B) 1800 ÷ 120 (metronome beat #) = 15 Frames @ 120 Beat #

For 25-fps,same Metronome to Frames formula by first establishing the divisor factor .....
60 seconds x 25-fps = 1500 (frames), and so on (you know what to do).

Using above very simple formulas, you need to ROUND OFF decimal fractions. If decimal fraction is 5 or more, you go up the next whole number. If it's less than 5 you stay with existing whole number. Examples: 10.22 is rounded off to 10, but 10.55 is rounded off to 11. Get it? If not, take basic math refresher course.
