I've got my Asus yesterday, I did upgrade to Win 10 Already and installed vMix free trial for now. I was able to get input to vmix from Gopro 3+ via BM Ultrastudio mini recorder via HDMI. However Ultrastudio management shows me 1080i 50, but I think I set camera to 1080p. I can't change it in BM software, but hope it is 1080p in real. In vmix at start I set 1080p 25fp and I am able to see the video, just don't know what is the real resolution.

CPU is at 3-4 % by using one camera - that's perfect. Do you think that Magewell eats more CPU?

I am really surprised by vmix's low using of cpu. In that case even Macbook with geforce 750 with 4 camera has to be good enough!

Yes you are right but via hdmi I can't see option to set it on 1080p 25 or 30, only 50i.

Regarding heavy encoding, am I rigjt when I think I will not need to do that because through external output video will go to teradek bond II - hardware encoder?

Bond II is device which combine both encoder and bond capabilities. Bond I was just a bonding machine without encoder (cube was needed). Vidiupro is something like Bond II but can use only one USB modem, so if you need more cellular connections to bond, you need to use iphones - and I don't believe that it can be stable by bonding mobiles phone's 3G/4G connections. However the price of Vidiupro is really the best - 1000 USD (Bond II is about 3,500 USD).

Btw. I returned my Asus already - it uses 19.5V and 9.23A - so not able to use additional battery pack (for example one produced by Lizone). For macbook pro I can use it so now it's totally clear for me - I have to use macbook, ordered already - I also made an agreement (just to be 100% sure) that I can give it back in two weeks without penalty.

On Asus 2 days ago I tried to use Multiview with 2 inputs (one gopro and second was HD Asus laptop's webcam) and GPU utilization increased to 40% (from 11%).

Hey Guys,

I have AJA Io 4K 4K and HD I/O for Thunderbolt 2 and Vmix now I want buy laptop which one can support HD live streaming and Live Recording kindly advice between

MACBOOK PRO 2013 15.4'' I7 2.3GHZ 16GB 512GB NVIDIA GE FORCE GT 750M 2GB DDR5

or


Asus ROG G751JL-DS71 17.3" Full HD i7-4720HQ 16GB 1TB 2GB nVIDIA GTX 965M


Plz advice.

Hello Gemain, believe or not, I faced against the same dilema. At first, I bought Asus which you mentioned.
It's good computer and maybe better choice for you if you don't plan to have portable solution at all. I had to return this Asus as it uses very unusual electric power (9.25A) and I was unable to find external battery bank which can carry 9.25A. So I bought Macbok pro 2014, the same as you described but slightly better processor (2.5Ghz) - because for macbook you can buy Lizone 60000Mah battery bank which can power your macbook for another 2-3 hours during the streaming.

Asus is for sure more powerful, but it's really huge and it's not so easy and comfortable to wear it, to manipulate with that. But, if you really don't care about portability (probably not if you bought AJA Io 4K which is not portable and needs wallet outlet) go for Asus.

For me, only choice was Macbook as it can be powered via battery bank and have 2x thunderbolt ports so I can use 2x Blackmagic Ultrastudio mini recorder + 1x Magewell XI100 USB 3.0 - so 3x camera inputs at all.

I will post new topic once I will have all the equipments. At this moment I tried MBP with only one mini recorder. However I started to use OSX for "sofa surfing" because it's really comfortable and don't need to use mouse and battery life is better :)

In Q4 Lenovo will start to sell Laptop with XEON processor, windows inside and 2x thunderbolt ports!!! :) However I expect battery life to be 1 hour :)

Responded to this via private messages. I usually work with 1080i50 inputs. However I do use 1080p60 on gopros.

If I have used two go pros @ once directly to the MBP it's been by accident or just quickly testing something and not in production mode.

So I have not tested 2 x 1080p60 into a MBP.

I have tested 1 x 1080p60 and 1 x 1080i50 for long periods of time.

Also tested.

3 x 1080i50 + 1 x 1080p60 for long periods with the aid of a Belkin Thunderbolt 2 Dock to get the extra 3 x USB3 full speed usb ports.

I did do another input, but that is where my MBP ran out of grunt. It worked for about 10 minutes, but my cpu was to high so I put the 5th camera away :)

So with the Belkin Dock and a MBP:

4 x 1080i50 + 1 x 1080p60 works, all via Magewell capture devices works but the i7 quad MBP 2014 really didn't have the grunt to do that and encode my stream as well at "safe" operating levels.

My advice @ 4 inputs, put your laptop away and move to a desktop :) I also have a Desktop with 10 Inputs, 4 x HDMI via Magewell Card, 4 x SDI via Magewell Card and 2 x Aver Media. If something needed all those inputs I would use that instead. MBP is good on smaller jobs. 2-4 Cameras.

5 is "possible" but you are pushing your luck. I can not foresee any reason why you couldn't run 2 x 1080p60 signals in @ once considering I've run 4+ 1080i50 signals in without a problem. I have not tested that config, so geniusweb you need to do your testing. I'm saying in theory it should be OK. In practise, you need to try it and post back to the forum.
