Smpte Text Overlay

[iconoklast]

I am creating a mocked-up security camera view and I want to display the date and time as a text overlay. I can easily display the current frame of course, but I want to format the text like smpte (HH:MM:SS). Can anyone point me in the right direction? I am using Nuke 5.

push $cut_paste_input

Thanks so much Diogo!

I am new to Nuke, and I am trying to modify the script to include hours (and not include frames). Here is my attempt to edit

Text {
message "[format %2.2d [expression int((frame+offset)/108000)]]:[format %2.2d [expression int(fmod(floor((frame+offset)/1800),60))]]:[format %2.2d [expression int(fmod(floor((frame+offset)/root.fps),60))]]"

For this project this is perfect, since it is only a mock-up.

Can I also use this script for accurate timecode window burn, or do I need to modify it to be truly accurate at different frame rates? For instance, would I just swap in 1440 instead of 1800 if I am working at 24fps?

thanks again!

Hi David,

You got it right.

I think if you replace the 1800 for [expression (root.fps*60)] and 108000 for [expression ((root.fps*60)*60)] the expression will update according to the project frame rate.

Cheers!
Diogo
