How can I create a varying letters in size effect in davicni

I want to create an effect like this in DaVinci
Where the size of the characters slowly falls off
Can Someone help me on how I can create this


Thank you so much in advance

I don't know about Resolve but in Fusion you should be able to achieve that with a simple expression in the text size control based on, subtracting the frame number (time) multiplied by a suitable constant, from your initial text size. It would also need to be synced to the write on. If I was more familiar with the text node I would post a example but I don't want to give you a bum steer. in a manner of speaking.

OK....so, this may not be the most elegant, nor efficient approach....but.... you could do something like this with a particle system ("no snickering at the back!")

I quickly put something together (just copy and paste it into fusion). In this comp, the effect (at least part of it) is done 1 letter at the time (hence slow, not efficient etc). The advantage is that you can place every particle (letter) exactly where you want it to be (combo of sine, cosine and then an offset in the z-position to give you the spiral).

For performance purposes I gave the particles only a life of 1 frame (reduces calculation) and then used a trails node at the end to "capture" all letters. So, this only works well if you play it from start till the end; you can't play it from somewhere in the middle. If you play with the parameters of the pCustom, make sure to restart the trails node.

Hopefully someone will come up with a (much!) better approach, but if not, maybe something like this can be of use to you.

I wasn't snickering, but if I turned reading your replies into a drinking game where 'particle systems' was the word to watch, I'd be drunk a lot.

lol! Yes, and throw pCustom into the mix, and you'll be legless!
