Question

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.

Hi default9jgfnszskwy6!

Sorry about the trouble. Phone recording videos might have variable frame rate. This could cause performance issues. Have you tried transcoding footage through HandBrake and see if that improves rendering? https://handbrake.fr/

 

Let us know how it goes.

Thanks,

Kartika
