Hey guys,
Been trying to research this on my own, but I'm not having any luck. What do the grey boxes mean on certain clips in your timeline. There is a green dot over them, which I know means that the clip needs to be rendered, but I don't really understand what the grey box means. Its in the center of a clip on the timeline and there is a letter insde the grey box. The letter seems to change depending on the project I'm working in. The clip I'm rendering now has a "c" inside the grey box. Not all clips have them, and some do. I want to understand what it means.
Thanks!
