Greetings. I'd like to have something like a bullet list on screen where I can add bullets as the video progreses

• Item one
• Item 2 after 5 seconds have passed
• Item 3 after 5 seconds have passed

etc. Right now, I only see a way to add one whole block of text.

can you provide an image about what you want to made?

if this is a very long list.. you need to use "rotoscoping" to add the "bullets" (with 2 images.. one is the text with empty circles ... and 1 , the rotoscoped with all the filled circles)

if the list is just 5-8 items.. you can make 5-8 images with gimp with the correct "animation" .. and just switch from an image to the next (transparent PNGs)
