100+ Hours to Export 3 Hours of Footage

[alldread]

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.

I could reduce the settings on the bitrate, but I don't think it would cut my time to even 8 hours, which I would still say is quite a ridiculous amount of time to basically re-encode footage.

Yes, I just want to clip off the ends of the footage and nothing else.

Nothing is added to the sequence at all besides the video that was automatically stitched together in camera.

Is this just not the way to be doing this? I don't know what else I would do to speed this up because I'm not going to have my computer render the rest of the footage I have for 600 hours and watch it next month.

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.

The computer is using a regular data ssd for th boot drive and I have the files on an ssd plugged in with usb 3.0 and exporting them to another ssd with usb 3.0

The USB3 drives can be quite varied in actual data transfer times ... the Samsung T3 and later drives are very fast, some others rather slow comparatively. Which drives are they? And have you run one of the disc read/write sustained test utilities on them?

I'm doing the same video on three different computers. One just off the base hard drive and that time is also 100+ hours.

The file has been exporting for 13 hours so far now and it's only maybe 15% done with another 80 hours to go. There's no way that people wait for days to export a lower than 720p video even if it's a USB 2 drive. I've never had this issue before rendering any files using any combination of harddrives.

I unchecked "VR" for one video and it still gave me the same estimated time.

Those times are so long, it's maddening for you and I don't understand why you are getting them.

I would suggest going to the Hardware forum linked to the right side of the Overview page.

Also, Bill Gehrke has his PPBM8 page with info on hardware that just works, plus the benchmark test that gives you a definitive and detailed look at your hardware working actual PrPro processes. That would show your bottleneck.
