Want to add a sped up timecode to a video- is it possible?

[Orla38643777z5f6]

I have a 20 second video which was recorded over 72hrs and need to add a clock to it, counting up to 72hrs. I have tried to offset the Timecode but can't figure out how to actually make it count up faster than normal time. Is there a way to do this in Premier or After Effects? Thanks

Animate the effect's values with keyframes. Same for the Numbers effect.

Hi Mylenium,

I can't figure out how to animate the effect. Could you explain in more detail? Thanks.

You can use an expression:

source text:

seconds = linear(time, 0, 20, 0, 72 * 60 * 60);
hh = Math.floor(seconds / 3600).toString().padStart(2, '0');
mm = Math.floor((seconds % 3600) / 60).toString().padStart(2, '0');
ss = Math.floor(seconds % 60).toString().padStart(2, '0');

`${hh}:${mm}:${ss}`

Thanks for your response. I keep getting an error message back (attached below). I'm probably doing something wrong but can you think of why that might be happening? Thanks so so much for your help, I am very new to after effects.

On which property did you add the expression?

I created a keyframe midway and added it to that, and also tried adding it to a keyframe at the end of the clip.

You don't need to add keyframes or any effects.
A simple text layer with the expression on it.
