Extremely slow rendering in Rush Hi,I have edited a video of a mobile phone recording, added some added graphics and background music. It's about 6 minutes long and impossible to render. The first couple of raw edited versions were fine, I didn't think it took too long to render - maybe 15 mins? But now, it suddenly would take over 4 hours to render the same video! I started searching for an answer to what had happended and tried a few tricks like restarting the computer, clearing old cache in Rush, syncinc the project, checking CPU activity, etc. Nothing did any good. Because now that I tried again - it suddenly says 13 hours to render !!! What is going on? Using a Macbook Pro 2020, Big Sur 11.2.3, with Intel Core i5 and 16 GB ram. Would appreciate quick reply. Thanks.
