Hello, fellows,
I finally configured my PC/OBS for recording 4 sources independently ( 4 cameras ), in order to edit later on Adobe Premiere.
That was made using the portable version. I created 4 independent OBS desktop shortcuts with their own settings.
It works like a charm, except for the fact that when recording 4 instances, the CPU goes to near 100%, although in iddle each
portable version consumes only about 2%. So, the problem is the computer which is too old for such a work, BUT...
There may be a reasonable codec setting thay I could use to improve.
My current PC and OBS recording settings:
i7 2600k ( 4 cores - 8 threads ), overclocked to 5Ghz, watercooler, 16GB RAM, SSDs, etc.
Recording disk: Seagate hard drive 8TB, 7200 rpm, sustained transfer rate around 220MB/s measured with crystal Diskmark.
OBS configured to 1080p canvas/1080p output, recording standard MP4 x264 CBR at 4000 on "veryfast" mode.
Although this is not the ideal recording for editing, if I raise from 4000kbps to let´s say, 6000, I can´t even run four instances at the same time,
My video card is old, an nVidia GTX 780, perhaps it doesn´t support the new NVENC that people talk so much about it, does it ?
So, after reading many posts on this foruns, I think there may be a reasonable CODEC settings for an optimal recording.
The recorded files are not big ( On this config, about 3GB/hour ), but I have plenty of space, I wouldn´t mind it the files were bigger but OBS don´t pound so much on compression. Should I use "ultrafast" instead of "veryfast" ? But that won´t have a worse video quality ?
Can´t I improve video quality by forcing a target video quality independently of the filesize without pounding on CPU ?
What about using VBR intead of CBR ?
I don´t know, but some of you may know, fellows.
Thank you for any ideas and suggestions.
