Who - me I’m a professional dj based out of Vancouver Canada.



What: I produce a radio show online.



When: asap start once I am assured all the specs will handle my concerns. With zero issues.



Where - recorded in my soundproof recording studio.



Why: as a professional dj. I am going to run a radio station show out of my studio.

And I wish to use 3 cameras (one GoPro hero 5, an iPhone 11 and and iPhone X (two obs webcam apps let me use iPhones as webcams and cam link hdmi to usb adaptor allows the GoPro to be a webcam). There are two green screens one for each scene. And visuals will play in the background. One scene is an overhead GoPro and a in front iPhone 11 dj set up with visuals behind dj and animated overlays in front of dj.

Other scene is on the couch with green screen behind snd used for commentary.



How: here is my gear and issues:



So my computer specs:

  1. CPU= intel core i7 -3770k cpu@3.5GHz
  2. Graphics card = NVIDIA GeForce GT 640
⁃ both were running at 70-75% when streaming live 3 cameras no visuals



Directly plugged into internet no WIFI.



Internet speed:

Shaw website speed tester:

download = 75.5mbps, upload = 14.4mbps



Shaw internet speed testing website Said:

Internet connection is very fast

  • should be able to handle mutiple devices streaming HD videos, video conferencing and gaming at the same time.




I'm running

OBS

- streaming to twitch.



Into computer:

1. Camera 1 - Have GoPro 5 filming at 4K 60Hz into a elegato can link 4k hdmi capture card into usb3 port

2. Camera 2 - iPhone 11 filming 4k 60Hz running into usb 3 hub into computer usb 3 port

3. Camera 3 - iPhone X filming 4k 60Hz running into same usb 3 hub into computer usb 3 port

4. Steinburg UR44 audio capture device usb 2 running into usb3 port. (Capturing mics and dj gear)



Running apps on desktop:

- iTunes to get iPhones working as webcams

- OBS - to record and stream

- Internet chrome - for twitch





OBS has Mutiple scenes:



1. Dj scene

- contains GoPro overhead camera

- iPhone 11 in front camera

- visuals (moving video) on the green screen.

- audio capture



2. Couch scene

- iPhone X in front camera

- video look on green screen

- audio capture





I'm worried my computer is not fast enuf to handle the recording and streaming at the same time.

  • During testing when streamed live and recorded video thru obs at same time video was glitchy. This was without the green screen videos in background which I wish to add.


Is my computer specs good enuf for overlay visuals for streaming ?



computer specs:

  1. CPU= intel core i7 -3770k cpu@3.5GHz
  2. Graphics card = NVIDIA GeForce GT 640
⁃ both were running at 70-75% when streaming live 3 cameras no visuals



Is this good enuf / fast enuf ?

Or should I consider upgrading and if so to what ?



Can a new graphics card run well on my cpu intel core i7 -3770k cpu@3.5Ghz ?



Or would both need upgrading ?



All my fans and power work and be fine or do these need upgrading too ?



♂️♂️♂️



I have no idea. I’m not a computer expert.

But when I build this computer years ago it was too if the line for music production.



Will this meet my needs ?



Any obs setting I should consider ?



Any help is much appreciated

And I’m a newbie. I don’t speak computer language. So go easy on me

please post an OBS LOG of an Session

but
2. Camera 2 - iPhone 11 filming 4k 60Hz running into usb 3 hub into computer usb 3 port

3. Camera 3 - iPhone X filming 4k 60Hz running into same usb 3 hub into computer usb 3 port

only one 4K Device on one USB 3 root HUB !

a New Nvenc Gracard can help to save the load from the GPU what encoder did you use software or quicksync ?
hope you didnt use it to stream and make music at same time !?!?

Thank you for your response cycleMatt

the two iPhones seem to work fine in the single usb3 hub. But I will try separate.

no not producing music. Stream is just for djn music. Radio show. Live.

I do not know how to post aOBS LOG of an Session

I just switched to the Nvidia encoder but I was using the x264 encoder for the issues I stated.

do you think my cpu
(CPU= intel core i7 -3770k cpu@3.5GHz)

can handles new updated Graphics card NVIDIA GeForce GT model ???

short version -yea, that CPU is too old, therefore under-powered, for what you are trying to do [assuming you don't intend to become technical expert on PC, OS, OBS, and more to get this to work]
real-time video encoding is demanding work. That is an 8 generation old CPU... yes it can stream, but dealing with 4K @ 60fps seems unlikely (but I never tried on something that old...). TO get something to work, most likely you'd need to learn to optimize OS and OBS for low resource streaming, which means limiting effects/filters and other apps running at same time (most likely).
Please take others input over mine, but I be REALLY surprise if you managed to get real-time video encoding working with a bunch of cameras and green screen (chroma keying) working on such an old CPU, regardless of encoding offload to GPU.
What exactly you need, I suspect, is VERY hard to specify, as it will depend heavily on the effects you want to use. And how long you want the system to last. For example, most streaming today is at 720p/1080p, though 4K streaming will become more mainstream over time. If you buy something, do you want it to last 4+ years [and handle increasing sophistication as you learn more over time]? Do you want to be able to do video editing on this same PC (similar, but slightly different requirement). etc

Using something like an Atem mini (Pro) could help with your current setup, as video terminates into Atem unit, and only single video stream sent to PC... but means you have to control both Atem (or other video switcher) and OBS... like so many things, each has its own trade-offs
