you are right, any recommendation where i can go to learn ?

Why don't you contact directimaging or tegas broadcast as they can be one stop store for everything related to broadcast equipments,I'm sure the salesman or manager will gladly take you through what to buy.Tegas is the more high end stuffs while directimaging has wider selection of midrange price products.The camera is the least of your concerns as the live stream system is more important,any camera with hdmi/sdi signal can be use. For the money any midrange Handycam should do the job. If you are diligent enough ebay can open up the door for used equipments.
From experience don't skimp on audio as the cheap one really will give you more headache than solutions.
Most of the capture card comes with their own software,it's a matter of choice and some prefer to work on other softwares.
If you are looking at TV broadcast quality,be prepared to look at 100s of thousand price tag. It's not the camera that cost so much but the system of switchers,decks,monitors,media stations,editing bay and storage that are costly.

Thanks for recommendation, i will look into that, im not looking to build high end broadcasting TV.
Honestly from what u listed like decks, monitor, media stations, editing bay and storage, i am
Im trying to find suitable rig for Mac platform that enable me tor stream with chroma key technique, after some search, the newtek tricaster mini seems can get it done for me, but i dont know if that what i need.

Don't worry about the TV broadcast standard, it's more for those armchair critics who thought production begin and end with camera lens and body.
Tricaster mini is expensive,look at blackmagic atem instead.The basic one is around usd1k.If remember correctly it comes with firewire output port. Make sure imac max out ram and hope it can handle the heavy process. or use imac for control deck while built a fast pc with ssd, max ram and reasonable gpu power to handle streaming. There are plenty of YouTube video for blackmagic atem.

Yup. I am currently looking at blackmagic atem, quite number of people recommend me that too. This is what i need i guess.
Really appreciate your guide.

Is this what are referring into?

Sorry just stumbled upon this thread. All the discussion so far on hardware. What about the software or expertise?
I worked on a project with NatGeo before and I can roughly tell u what they use for videography. But it also depends on what u wanna do... your workscope etc.

When I am not too busy, u can come and talk to me. I have my own studio etc.

Hai, cool. Right now i am focusing on the hardware to give my company management knows, what kind of tools that i want to use.
But in terms of sofware for audio i plan to use Audicity and for video, is Adobe premier (or should i use final cut pro?) because i want to be able to do chromakey while live streaming

Its actually not a big studio at all, just a small setup for a start up, that got the hardware needed. I still trying to figure ou the architecture from Mac to ATEM Television Studio to camera.
Do i need to connect it to audio mixer? what kind of hardware that i left?

You can use any external monitor to go with ATEM so you don't buy the BlackMagic monitor.
You can hook up to 4 hdmi or sdi camera to ATEM.
Audio mixer hook up to ATEM via XLR to SDI conversion.So all your audio feeds are balance via mixer and in sync to footage.
ATEM connect to control deck which can be your IMAC or any laptop via hdmi/usb (still unsure about firewire).
ATEM output HDMI/SDI to streaming PC.
During streaming,try not to use the streaming PC for any other apps.
Your IMAC and Streaming PC will be media station for anything about photoshop,premier,jpgs,ppt,audio,etc....to be use during filming.Need to prepare all your files beforehand.
ATEM came with it's own software or get telestream wirecast on trial before purchase. It may look complex to use, once you grasp what does what, it's quite easy. Study the flow of game shows, concerts or even news programme. How they switch angle during narration so you get the hang of what to do.
The software and hardware is the easy part.
The most challenging of it all is the actual filming of your stream.Duration, template, direction, music, script, engaging speaker/presenter, teleprompter, manpower and logistic will be the next hurdle to overcome.

So i need to have audio mixer too. Can suggest any?
For the audio part, when im using wireless mic and it attached to the person who streaming or even using a wired mic, is it go straight to my audio mixer and then connect it to my ATEM using XLR to SDI conversion?

Audio mixer not my expertise as I usually the one overlooking the filming.You can check out some of the youtubers set-up or back to that adorama video I posted, they look pretty legit. As for wireless mic there are few options to go about as in ear buds, clip on,or commando. Wired mic is messy to use as you do not want wired running around filming area. Usually on my end, I just hired a proper audio operator on the job so I have one less thing to worry about and within my budget.

Cool, now i need to find suitable audio mixer for my setup.
I am planning to use wired mic to be used as a recording setup, not to be used as a streaming setup.

A lot of my juniors make the mistake of making heavy investments on equipment, hardware, overheads etc when starting a new biz.
I am more a marketing person so perhaps I can share this with u another way of looking at the biz so that you can avoid mistakes right from the start:

1) Who is your target audience? Your potential clients?
2) What kind of money do you think your clients can spend on your services?
3) Why would your clients spend with you vs yr competitors? If you have a good network, or your dad is a VVIP, then maybe half that question is answered. But how far can you go on relationship mktg? Is here a point when you can compete on your own?
4) Who are your competitors? What can u do that they cannot do?
5) Who will be your frontline mktg team and how capable are they to reach the target revenues u set?
etc

I would attempt to answer all the above questions which would then determine how big your outfit should be, and what kinda hardware you should invest in. Cheers!

Basically the studio wasnt for me, and it is intended to be as a in-house studio for my company. To shot products and livestream that need to be air through mobile apps.
In terms of client, we already have the client that will use our products. The only worry I need to have now is the setup of the studio and how i can use them, I have very limited knowledge about broadcasting, and I want to learn, the setup and all.

Oh... I see. In that case, because the videos are only for mobile apps u may not require such high-end eqmt... just saying.
For us, we typically shoot 4K and downsample to 1080 because we want the details. And also partly because that's where the future is headed, 4K.

I'm curious what you will be live streaming? most just take a video then edit it then upload it online. what do you need shot live? Fo. Live tournaments or something?

Im not looking for 4k either, 1080 will be enough, we also planed to stream it on web. from what i gathered, maybe the architecture something like this, just that the camera, mic, and audio is different.


What do you think? any changes i should make?

An educational apps streaming, post video online is easy, but to record it online, plus with chromakey technique, its a bit challenging to me.

I still haven't figure out yet how to stream it? using livestream.com?
