I like to do calculations using SMPTE timecode.
These are times using hours:minutes:seconds:frames
Frames are parts of a second. In my case they are always 25 frames in a second. 00~24
I want to do calculations like:
16:23:17:14 + 00:09:09:15
and the the result should be:
16:32:27:04
How can i do this?
This macro so do the trick.
The calculations are complicated enough that it makes sense to me to do this in script, JXA in this case.
Please let us know if you have any further questions.

I am astonished.
And speechless.
just, wow.
Thanks a lot man! I will try to implement this in a macro i am thinking of. The goal is in ProTools to find a timecode spot within a file, so maybe i have to subtract instead of add, but i will puzzle on the script to see how to do that.
Just wow
Hmm. This is beyond my skills and smartness:
How do i change the script so that it subtracts âLocal__TimeCode2â from âLocal__TimeCode1â?
That would be an easy change in the JXA script:
//--- CHANGE This:
var totalSec = round(sec1 + sec2, 4);
//---TO This:
var totalSec = round(sec1 - sec2, 4);
// --- OR ---
//--- ADD KM Variable to Specify the Math Action ---
var mathAction = kmeApp.getvariable("Local__MathAction", {instance: kmInst}) || "ADD";
if (mathAction === "ADD") {
var totalSec = round(sec1 + sec2, 4);
} else {
var totalSec = round(sec1 - sec2, 4);
}
Questions?
questions? no, not yet!
After some tweaking it works here! So good!
I will make the macro better in the next days and later iâll post it here.
I am making a macro for ProTools that will jump my cursor to a specific original timecode within an audiofile. This is something ProTools cannot do.
I just managed with the help from you!
Hmm. Something is wrong in the calculator.
See this result.
The result of
16:22:09:11 - 16:21:36:00 should be 00:00:33:11
My apologies for this bug. It was caused by a JavaScript round-off error, which I should have caught and fixed. The bug is now fixed.
I also added the Math Action option to âADDâ or âSUBTRACTâ the timecodes.
Please give this a thorough testing, and let me know if you find any issues, or have any comments or suggestions.
I have updated the macro in the above post:
You keep on making me happy man!
It works here, i have to start using it for a while to find out how it performs in actual situations but it looks promising!
One question; I noticed that the variables you used get deleted after the whole macro is finished.
In the macroâs that i make the variables and their contend stay alive. They do fill up the memory a wee bit, but this way they can be used in other macroâs as well.
What makes it that the variables that i used in your script are deleted after the last action?
They are deleted because they are "Local" Variables, which you can identify because they have a prefix of "Local".
The script I wrote uses these Local variables. If you wish to retain the information for later use, the easiest thing to do is to add an Action that simply sets a Global Variable to the Local Variable.
I like to use the naming convention of "DND__" as a prefix for my Global Variables, which stands for "Do Not Delete", a reminder to me when viewing in the KM Preferences Variable pane.
got it!
Thank you @Fokke and @JMichaelTX for making this macro, Michael you are amazing, very neat this can be done.
I have uploaded a couple personal updates incase it helps anyone's workflow that comes across this. I am in America so 25 is not a frame rate I ever use. Not that 29.97 makes any sense for these calculations it works fine for this. Feel free of course to change to 24 or 30 or whatever.
The macro is designed to make text selections in another editor of a mix down (bounce) that has several songs in a single session. Give to a client/artist and have them give you time locations they want edits done. With this macro is helpful for finding where 2:30 seconds into a song is by placing your cursor at the start location of the mix down (which could be at any location other than 00:00:00:00) and finding the new location in the Pro Tools timeline.
Do note if you weren't aware that Pro Tools does allow you to just press
to add or (minus sign to subtract) from a current location. So for example if you were at 00:20:55:29 and ran the above you would then be at 00:21:44:29 which would be the same location as if you just ran this macro but with out all the steps. It does save you a little time but you have to highlight selections in your text document.

Hi Skillet,
Yes, i am aware of the fact that the main counter can be used as a calculator this way.
I needed a calculator like JMichaels made for me (us!) because i was looking for a method to jump to a user given âoriginal timestampâ position within a clip.
