I found what appears to be a rounding error in the formula for converting time to timecode. It could be that the error is introduced because the routine is a base 29.97 fps and I’m using 30 fps. Whatever the reason, when a number on the hour such as 12:00:00 AM was used the formula would convert it to 11:98:99:00 during the conversion. This wreaked all sorts of havoc every few rows and screwed up the frame count but only on even time stamps such as my example. The solution I found which looks like it’s going to work is to change the formula in the formula bar to:
=timetoTC(A2+0.00000001) rather than =timetoTC(A2).

If you’re having this problem try that. Thanks again to the site owner and the person who created this routine. Hopefully my responses here will help pay back their efforts

I had a problem where I had to sync a device with a time stamp to a camera running TC at 30fps. The format of the device is hh/mm/ss. The time code is hh/mm/ss/ff. The device time is needed to do an animation in Adobe After Effects that will sync with the camera TC. The problem was that AE needed frames (eg. Cam TC 00:00:01:00 = 30 frames) but when the time stamp data (00:00:01 = 1 second) was used the seconds were interpreted as frames. The above example would end up on the timeline as frame one rather than thirty. With me? I’m plotting thousands of frames and can’t manually type in frames into the time stamp in Excel. But Excel won’t allow (or I don’t know how) frames in its time formats. Here’s how I solved the problem:

I loaded the macro per instruction and hit ctrl t. I also made sure it was activated in Tools>Add Ins.

I made 3 columns.

Col A — First you need to Format>Cells>Time> 1/35/55 AM/PM (h/mm/ss AM/PM) The Macro understands and drops the AM/PM during conversion

Col B — Second you need to Format>Cells>Custom>00\:00\:00\:00 (or drop frame)

Col C — Third you need to Format>Cells>Number>Number w/no decimal places

Paste your time stamp info in Col A. I am using 12 hour based with AM/PM.

Select Cell B1 and goto Insert>Function>(select all)>timetoTC>select A1 Column cell from helper and that should return the time stamp with frames now added to the end as 00. (eg 20:57:55:00)

Select Cell C1 and goto Insert>Function>(select all) TCtoframes>select
B1 Column cell from helper then fame rate and it should return 2264250

That should work – if it doesn’t check to make sure you’re formatting the columns properly. That’s the most important thing and it may take a while for you to figure it out for your own project. Just noodle it till it works. Nice little plug in saving me lots of effort. Thanks

If you haven’t tried it go to Tools>Add-ins and check the Tc box.

I missed that part but eventually figured it out.

Also, the formula instructions indicate semicolons where a lot of users will actually use commas. This is because a comma is a decimal in many countries, so the semicolon is used there instead. If you’re in the US you probably want to use commas.

E.g. “=TCplus(TC1;TC2;fps)” should actually be “=TCplus(TC1,TC2,fps)”

The formula I can’t get to work is TCtoText. I input “=TCtoText(1154325)” and should get “01:15:43:25″ back as a string but I always get “0″.

If anyone has any advice on that function please post here.
