[NEED HELP] 4k - 60 FPS Recording

[XXYXYYXY]

Hi guys

Im trying to record GTA V at 60 fps ( or 50 i dont care ) at a resolution of 3840 x 2160 . But i cant figure out HOW.
When i try to record my PLAYING frames drop to about 55- thats ok. but the VIDEO FRAMES never get higher than 15. in the pause screen or in the start menue it goes up to 30 or 20.
But my cpu never goes higher than 60 %. So there HAS to be a way to push my recording Frames up ....

I have a intel 3770k - Nvidia Geforce 680 2GB - and a Samsung SSD 830 Series or Samsung 840 EVO ( no difference which one )

Im using the Lagarith Lossless Codec- Frame rate is 60 fps- Scaling 100 % - Multihtreading allowed. and at Advanced settings i "use all logical Processors" -> 7.


PLEASE could you help me...

THANKS



EDIT :        Same problem with FIFA

So it has to do something with Processor or Hard Drive

Try utvideo: http://www.videohelp.com/software/Ut-Video-Codec-Suite

Or magicyuv: http://www.magicyuv.com/

Those are the two fastest lossless codecs (on encode side) I know of. If you can't get to 4k60fps with them, then most likely your processor or hard drive isn't fast enough.

first of all. Thank you so much for your help.

I have small improvements with these programs- but i cant imagine that my processor is too slow. i have a i7 3770k and the utilization never goes higher than 50 oder 60 %...
What writing speed does my ssd needs to record it properly in 30 or 60 fps ?

[aznricepuff]

Your hard drive needs sequential write speeds greater than or equal to the bitrate of the video you are recording. For 4k60, you will probably need around 500 MB/s write to be able to record in RGB format, 33% less in YUV422, and 50% less in YUV420. For 4k30, just divide those numbers in half.

If you have not already, try dedicating two threads to dxtory. I did not read the log so I do not know if you already did. The only other thing I can think of is your write speed needs to be very fast and make sure it is the only thing being done to that drive. So try not running games or programs off the drive you are recording to.

math time:

3840 * 2160 @ 60fps = ~1.4GB/s for RGB lossless. Even with magicyuv/utvideo/lagarith compression being somewhat good, you'd still probably need atleast 1GB/s storage. Lowering your colorspace could help a bit, but you'd still need very fast storage.

OR, you'd need pretty ridiculous cpu to use a codec which could compress better with consistent 60fps.

OR you'd need some gpu accelerated video capture, like shadowplay or such.

edit: the math if you are so inclined

Code Select Expand


3840 * 2160 = 8294400 pixel/frame
8294400 pixel/frame * 24 bits/pixel / 8bits/byte = 24883200 bytes/frame
24883200 bytes/frame * 60 frames/second = 1492992000 bytes/second = 1423.828125 MB/s
