I can't record 60fps with screen capture

Question

cpu: i5 2300

m/b:asus p8h61-m

ram:2g*2

vga:hd2000

hdd:s470+seagate 3tb

os:windows 8 pro x64

When I record desktop, screen felt so freezing, so i recorded few seconds and i found

fps stuck in 20 fps and cpu usage was below 5%.

My setting was 60 f, 5000 kbps, 80 quality, capture mouse point and the others were default.

so what should i do?

Answer 1

What screen resolution are you trying to capture?

Are you recording a static desktop, or is there motion such as a video or animation playing in an open window?

What is the current write speed on your hard drive?

Answer 2

i need 1024x768 and i captured dragging a window.

my ssd has 250MB/s of seq read, 160MB/s of seq write, 20MB/s of 4k read, 38MB/s of 4k Write(qd=1), and the capture file was saved at ssd, and the ssd write speed was 200kB/s maximum which indicated task manager's performance tab. it product same result when i save at hdd(178MB/s of seq read, 162MB/s of seq write).

and i just found that capturing at 320x240 product avg 50f (wave 30f~60f), at 800x480 product avg 30f, but i can't capture all screen with these resolution. 

Answer 3

first off, change the 5,000 kbps back up to the default (30,000) and try again. The bitrate can be set up to 300,000 kbps, so feel free to try higher bitrates also.

Another thing you can do to improve frame rate is disabling Aero. Are you capturing the screen while in a Metro style application (the new tablet like apps) or in a more conventional Windows application? I don't know if that makes a difference, but it's something to compare against.

All that being said, if you ever want to record at higher resolutions and want to keep that framerate, you'll have to turn to one of the many hooking type video capture applications. EE Screen capture is not capable of capturing, let's say, 1920x1080 60 fps video even on very powerful systems.
