Honestly this post is a question to anyone why might know, as I have been running into something very frustrating with DaVinci Resolve, and that is, why when I duplicate a timeline do I lose the render completely and have to let it sit and re-render footage that is still rendered and has not changed from the previous Timeline (DaVinci’s name for a Sequence).
This is especially frustrating while working on my short film, which has full color corrects and a good deal of noise reduction, so a render can take hours and hours.
I looked for this on the DaVinci forums and don’t see anyone mentioning it, nor any posts on YouTube.
