I'm trying to encode some VP9 webms, but they're taking forever to encode for some reason.
VP8 encodes just fine. I'm just trying to encode a 01:30 clip with only about 2000 frames and a bitrate of 3000 kbps, but it takes like 3-4 minutes just to get to 1%. I'm using XMedia Recode 3.3.3.6.
For some reason, the CPU usage is locked at 25% at VP9, even if I set it to high priority. What am I doing wrong?
what program are you using to encode?
can you post a screenshot of your cpu usage via task manager when it's peaked?

I've never used XMedia Recode so I'm not sure about any of this.
See if there's a way to increase the number of threads used. It sounds like it's only using 1 thread instead of presumably 4.
If there's a speed setting, set it to a faster speed. Most encoders should have this.

Sorry for the late response. Pic related shows all relevant information:
Left is the video encoding settings. Middle is the encoding process after about a minute. Right is the task manager.
The first pass of the encoding breezes in about a minute using about 40% of the CPU, but once the second pass starts, the CPU usage is locked at 25% as seen in the screencap. I'm making this post about 5 minutes after taking the screencap, and the encoding is now 52.91% done.
Am I missing something obvious? VP8 doesn't have this problem.
vp9 encoding is currently ultra slow , try setting quality to "good", threads to 32, and tile columns to 64, it should give a speed boost.
VP9 support on 4chan when?

25% is 100% on one core of a four-core processor.
If you want it to say 100%, you need to find a way of turning on multithreading, or just encode four videos or more at a time.

>Why do I get 100% on VP8s
That encoder probably has multithreading implemented properly while the VP9 encoder doesn't
use ffmpeg

xmedia recode is basicaly a gui for ffmpeg.
