I’m having the same problem, but worse. My computer isn’t particularly fast, but in CS3 I was able to render videos with a fair amount of speed. For some reason, Adobe Media Encoder is taking an hour and a half to render a minute and thirty seconds of plain and simple sd footage. I’m exporting to h.246, which I understand is slow to encode, but not THAT slow, and other formats take similar amounts of time. While rendering, Task Manager tells me that Adobe Media Encoder is usually using ZERO PERCENT of my CPU, and never going above 25%. Idle Process is using most of the CPU, with PProHeadless using the remaining bit (Although Headless sometimes reaches up to 50%)
Any help? Thank you. 🙂
