What the "VTEncoderXPCService"

Thanks. When I turned off iPhoto in iCloud, the problem resolved. I'd rather not have to do this, obviously, but unless Apple devises a fix for this (which seems unlikely since it appears to mainly impact older MBPs), it seems that I'll have to manually toggle iCloud Photos only when I actually have something that needs to be added.

This happened to me when I changed the location of my Photo library AND import a whole bunch of vacation photos/videos and gopro vids... So not sure which really causes this process but your idea about the "processing in the background" sounds about right. No issues other than the CPU running 120% on my late 2009 iMac.

By the way, I also have the VTDecoderXPCService running with quite a hight CPU rate

Kill the process in Activity Monitor and see what happens.

Same here but only when running Photos. VTEncoderXPCService consumes over 300% of CPU and the fans ramp up within a minute or so of launching Photos. Killing the process only results in it relaunching within seconds.

FWIW the 25GB Photos library contains mostly videos (many are slo-mo) taken with an iPhone 5s.

EDIT: And it doesn't happen on all Photos libraries. For example, I just opened a 97GB library and then a 157GB library. VTEncoderXPCService did not launch and the fans didn't ramp up. These large libraries have mostly still photo and standard video shot with a Canon elph.

MacBook Pro 15" (early 2011) with Intel HD Graphocs 3000 and AMD Radeon HD 6750M graphics running OSX 10.11.1

I have a MacBook Pro 15" (early 2011) and I'm having this exact issue with Photos. When I plug in my iPhone 6s, it opens Photos along with a heavy load of CPU from the VTEncoderXPCService. I feel like it only started happening recently. Once I disconnect my phone from Photos, VTCEncoderXPCService cools down.

The Photos Library that causes my MBP (early 2011 w/ HD graphics) to get too hot to handle was created by importing 355 photos and 381 videos, taken by an iPhone 5s, by dragging them into the Photos windows via the Finder. Almost immediately after import the VTEncoderXPCService jumped to 300+% of the quad core CPU and the fans crank up to max. Even with the fans on high the MBP’s case became very hot in the upper left hand corner.

When a clone of this Photos Library is opened on an iMac 27” the VTEncoderXPCService jumps to the top the CPU list BUT it consumes less than 100% of the iMacs Quad core CPU. After scrolling around and viewing a few of the videos on the iMac, then opening the clone on the MBP VTEncoderXPCService still occasionally becomes the top CPU process but it stays below 100% and the fans are quiet.

Comparing the package contents of the original Photos library to the clone after it was opened on the iMac shows that Photos on the iMac added over 4.3GB of Thumbnails, Previews and resources. So it appears that Photos is using VTEncoderXPCService to “process” the library in the background when new photos/videos are imported. This background processing is no big deal on our iMac but it causes our MBP to get much hotter than I think is good for it*.

You can reduce the volume of photos/videos being imported from an iPhone into the Photos app on the MBP by using Image Capture to copy the photos to the MBP. Then you can import the photos/videos in small batches.

* I’m sensitive to the heat and high fan noise because Apple recently replaced the "Logic Board 2.2 GHz" and "MagSafe Board" on our MBP. The symptoms in the days before the logic board failed were frequently running hot with the fans on high.

Likewise. The "VTEncoderXPCService" process starts as soon as a I drag a large video file from Photos to the desktop. The fan starts humming immediately. Ironically the video will not copy to the desktop. Photos just hangs in the process. No crash, and the app is functional. But the export progress circle does nothing, and the video does not export to the desktop. Running the latest of everything, 10.11 and Photos on a 2010 MBP.

it restarted all by itself

VTEncoderXPCService (1218) Parent Process launchd1

Its using 315% of my CPU. My macbook is hot and I'm afraid it is going to burn up.

These are the open files:

/System/Library/Frameworks/VideoToolbox.framework/Versions/A/XPCServices/VTEncod erXPCService.xpc/Contents/MacOS/VTEncoderXPCService

/usr/share/icu/icudt55l.dat

/usr/lib/dyld

How do i turn this service off ? A force quit and it automatically starts up again.

It's 100% Photos. After reading all the responses I went digging in Photos myself. In my case, I had Photos connecting to iCloud Photo Library in preferences.

The second I removed this connection, VTEncoderXPCService was virtually gone.

I guess the point I'm making is this appears to be centered around the Photos application.

VTEncoderXPCService and VTDecoderXPCService are associated with Photos App.

The best that I can come up with at the moment is a corrupt video file. In my case it appeared to be a slow motion video causing the issue. Deletion of the slow-motion video from Photos resolved the issue.

Look for corrupt videos in your Photos App.

I had the same problem.

Then I found out that I had closed the Photos app while it was importing some photos and slo-mo videos from an SD-Card. I restarted the import and when it finished everything was okay.

So I don't know what program you are exactly using when this started happening, but as far as I know VTEncoderXPCService runs, and runs at a high CPU usage amount if you use quicktime for recording, make sure you don't have quicktime running in the background.
