What is the best tool to make animated product thumbnail for PH Launch?

Keyshape is great for any kind of svg or gif animations https://www.keyshapeapp.com/

For https://www.producthunt.com/post... (and most of my other products) I created the thumbnail with HTML and CSS and then used https://getkap.co/ to record the animation and trim it so that it loops. From there I used https://ezgif.com/resize to resize and change the speed until I was happy with it.

I've just found this one: https://crello.com/templates/pro... Looks promising to make simple animations

www.get-leap.com make simple product gifs with quick edits like zoom into a feature, speed up parts of a video, and compress the final output
