Generator removed in the end of video

Hello, I need to add some seconds of black screen in the end of a video. I'll use them to show the closing cards on Youtube. I am using a Generator effect
When I render, though, the generator is removed. Why?

Generators need to made into compound clips if you want to render them out.

No, it doesn't.
Check what is your Render Range setting on Deliver page? See figure, pls.

I'll use them to show the closing cards on Youtube.

As a YouTube viewer, I'd like to suggest you not do that. Those cards are very annoying. When the video is over, just end it.

I think everything for YouTube should be preceded by at least 1/2 a second (if not 1 second) of black, and ended with 1 second of black. Otherwise, there's danger in having the end chopped off by a few milliseconds.

I have not had problems rendering generated black or bars or anything else at the end of timelines with source clips, but this will happen if you have a timeline made up entirely of generators (titles, bars, ramps black, BG color, etc.). Changing them to compound clips (basically just a background render) solves that problem, as Tero says above.

Thanks, next time I'll check the rendering range. I was sure it included everything but I could have missed something.
