Have anyone experienced with video recording in 4K?

Hi,

I would like to ask if anyone have experienced with video recording in 4K and if so, which HW you used?


Thank you.

Using the video recorder to record 3600 frames (1minute @60fps) at 4K with an i5-9600K and GTX3080ti took 3-4 minutes. Resulting files are 350MB.

Hi,


and did you try recording in RTX mode with the same settings? This is where I struggle with the total time.


Thank you.

No - that's too high resolution to be done quickly with my hardware - as Phil says you'd want to reduce resolution or framerate and/or increase your GPU power to get improvements.

@Martin K5, I think it is a feature of graphic cards to create live podbroadcasts for gamers. There are also video grabbers available with a low latency to store video files through an usb interface. You find examples to use OBS Studio to record or stream live video games sessions. At the end it is a compromise of frame rate and available hardware if you get suitable data for 4K video.

@Martin K5 , Please don’t try recording on a notebook gpu. Their performance is limited or hardware encoder are disabled.
