Film Frame Calculations
Pamela Harvey-White A friend had the same issue and asked for my help to calculate the duration between two cells in hh:mm:ss:ff (ff being the frames) format. I've created a formula that does the trick with precise results. It first subtracts hh:mm:ss and then adds the frames. If the subtraction between frames is less than 0, it subtracts a second and then adds the frames. Then it trims the text to ensure negative values aren't preceded by a minus sign.
This thing is not allowing me to attach files, so I'll just paste the formula here. In a table which has the starting time in cell A2 and the ending time in cell B2, it would go like this, with the duration in C2:
A2: 00:02:08:19
B2: 00:02:37:18
C2: =IF((RIGHT(B2,2)-RIGHT(A2,2))<0,TEXT(LEFT(B2,8)-LEFT(A2,8)-1/86400,"HH:MM:ss")&":"&RIGHT(TEXT(24+RIGHT(B2,2)-RIGHT(A2,2),"00"),2),TEXT(LEFT(B2,8)-LEFT(A2,8),"HH:MM:ss")&":"&RIGHT(TEXT(RIGHT(B2,2)-RIGHT(A2,2),"00"),2))
The result in C2 should be 00:00:28:23
- Hello! I'm loving this because I've been dying to find a solution for the same problem. I tried using your formula, but I don't have the right format for the cells with my start and end times. It's reading as text and cannot calculate as a result. How would I format the input cells A2 and B2 in this example?
Thank you!!If in A2 and B2 is something like this
values are always texts. One in A2 means 2 min 8 sec and 19/24 sec. Excel doesn't support native formats for them, we need to transform by formulae. If you are on Excel 365 or 2021 duration in C2 could be calculated as
=LET( st, A2, en, B2, frames, $A$1, k, 1/60/60/24, start, TEXTBEFORE(st,":",3)+TEXTAFTER(st,":",3)/frames*k, end, TEXTBEFORE(en,":",3)+TEXTAFTER(en,":",3)/frames*k, duration, end - start, TEXT(INT(duration/k)*k,"hh:mm:ss") & ":" & ROUND(MOD(duration/k,1)*frames, 0) )and result is also returned as text.
Hello,
I would like to thank you for the formulas you've created. They saved me a lot of my time.
I was wondering whether there is any formula which can find clip based on the name, count both durations and round it up to seconds?
For example:
EDIT_Clip_01
00:00:03:00 + 00:00:02:19 = 00:00:05:19 ≐ 00:00:06:00
Does it make sense?
Many thanks in advance for your help.
Best,
T.
