Question

Why do nested sequences render so much slower

I'm finding that rendering a nested sequence of clips takes massively longer than opening the nest and rendering the video content within. But then the internally rendered content doesn't work on the parent timeline.
 
When I say longer- I tested on a 10sec portion; Open the nest and pre-render the clips in DNXHD, I didn't get the chance to start a timer. Same 10sec of the compiled nest on the parent timetime, it's taking about 2 seconds on EVERY single frame.
What's so different?

Eric,

Sorry for the error. I do need to know, though: Why did you nest in the first place? Are you adding effects to the nest? The answer to this question may lead to the reason as to why.

 

Thank You,
Kevin

I had started doing nesting because of added text captions, but I just spotted that I had a denoiser on the nest container. Disabled that and it's playing back okay now. I've completely given up on using Neat Video in Prem but hadn't removed from that sequence (I probably did but lost my change in the last crash)

NeatVideo provides excellent noise reduction, but - as you've noticed - is very slow to render.

 

Sometimes I'll apply it to clips that need it in After Effects and then let AE or Adobe Media Encoder render the clips while continuing to work in Premiere Pro and then replace the noisy video clips with their NeatVideo versions by using Replace Footage... in the Project tab.

 

Of course, this means havin a license for the Premiere Pro version and the After Effects version of NeatVideo.
