Hi, fellow video editor for years now. (4 years in professional and casually since I remember using Windows Movie Maker at the age of 10 or something)

There are many ways to achieve this editing, but I'll share the 2 methods I would try to do.

Level 1 - The quick way
1. Go onto Giphy or Google, search the effects that you want.

Ex: If you want "smoke", search Giphy on Stickers, usually it's already in .GIF or .PNG.

2. Save the image and import it into your software editing.
3. You place it above your actual footage, in terms of video layering (timeline).

Level 2 - Related to Premiere/After Effect/Davinci Resolve softwares way
1. If say Google PNG and Giphy don't have the effects you want, you search on YouTube.

Ex: If you want "smoke", search by "Green screen smoke" and go into the rabbit hole of finding the right one you want.

2. Certain YouTube videos of VFx (visual effects) have direct download link for you. So you don't have to find convertors online. Some doesn't.

Ex: Search "download youtube videos" on Google.

3. Import your assets into your software editing and place them above your actual footage, in terms of video layering (timeline).

If using Premiere:
4a. Search "Color key" in your Premiere's Effect window.

If using Resolve 17:
4b. In "Edit" tab mode, go to "Effects Library", go to OpenFX, search "3D keyer".

Davinci Resolve 17 - Green screen tutorial

If using After Effects:
4c. After Effects - Green screen tutorial

5. Apply the effect to "smoke" footage. Use the eyedropper tool and pick the green screen colour. You may need to play around the settings yourself; threshold & softness.

Level 3 - Money can buy not headache way.
1. There are many professional VFx available to be purchase. You can try those and not gaining a headache. Depending where you are and the currency and financial you have, you can choose this option.


I like to use the first option and then only moving to level 2.

Hope this helps!
