Question

100+ Hours to Export 3 Hours of Footage

I have an i7 6700k @ 4ghz and exporting a 360 clip at 1920x960 takes 180+ hours and 1280x720 takes 100+ hours.

I'm not understanding why it would take this long to do this as I've added literally no effects. Is there maybe a way to just cut off the ends of the footage without having to re-render the entire thing, because that's all I ultimately want to do.

Hi alldread,


So to confirm, are the only edits trimming the start and end of the video clip? You do mention 360 cilps. Are you joining them?

Looking at your screenshot, the video is over 3 hours right? Have you tried exporting say 30 minutes to see how long that takes? Your settings of Target 11 Mbps and Max 12 Mbps will create a massive file. Try go down to Target of around 5 and see how that works.

I had a project that was taking a long time to edit provided by another person and it ended up being that he had inserted very large image overlays over 5,000 pixels wide that were resized in the video to around 1,000 wide. So, something that seemed relatively minor was becoming a major render hog.

Provide more information on what you're doing and that can help with further advice.

Also my CPU only has 25% utilization and my gpu is only at 10%. Not sure how to get these any higher, but that seems like a big culprit to me.

What's the disc setup on that computer? Normally when those numbers are so low, there's other issues going on. And ... you need to have minimally 4-5 times the final size of the file as it will be when fully exported clear on the drive you're exporting to.

Further ... if you're not resizing nor doing any effect using color correction or warp stabilizer, a few other things, the GPU isn't going to be involved as basic encoding is more of a  CPU thing.
