There is one step in the live streaming process that absolutely cannot be overlooked: video encoding. Businesses, schools, and other organizations live stream conferences, webinars, classes, and events to connect with their audiences. Well the difference between myself and a lot of the resellers out there are that I do this for a living and has done that for the last 20+ years.Live streaming is a business practice that is on the rise. 1 computer for mixing and streaming and recording with the shuttle. You could use a hyperdeck shuttle as a recording device instead of using 2 computers. With only 1 you have put all the eggs in the same basket. If you have 2 computers and something happens with the streaming you still have the captured signal from the other computer for later use. If you also uses the same computer for capturing the H264 signal you must make sure that your computer is powerful enough. It depends of what settings you use for streaming, HD uses more than SD. Second problem are that the task of streaming uses a lot of the available cpupower of your computer. In this case the streaming software will be in the background, you will also have some problems monitoring the stream because the other window will be on top covering it. I prefer to use 2 computers since if you only use 1 you get 2 problem.įirst problem are that 1 software need to be run in the background so you need to make sure that it still working when you switch to running the other software. If you have the extra money I would go for an extra card on the streaming computer to let that computer only handle the streaming and record the H.264 stream on the same computer that handles the mixing. I suggest to try to have 1 computer doing the streaming/recording and 1 computer doing the mixing. If you only need 1 input then you can use a input card instead but using more take a computer with much more cpupower. The point of using an TVS are that the load of mixing several signal (in TVS up to 6 inputs and 2 internal stores) are taken away from the computer. PC or MAC doesn´t really matter, use what you are more familiar with. You can record at the same time depending of the software you are using. There are cheap solutions if your software does´t support it, for example the mini recorder if you have MAC. Some programs like Wirecast can´t use the H.264 as an input but other softwares can, MXlight for one. You will still need an encoder to be able to stream. To answer your questions, no the ATEM doesn´t do the encoding it just produce a H.264 file in real time. Look forward to your replies - Many thanks! We also need to buy another couple of camcorders and HDMI cabling etc with our budget, so a Tricaster is out of the question. If somebody can help me on these questions above it would be a great help. If it doesn't stream, what's the point of it? Would it work better with a Mac or PC as the live mixing controller? Will recording it locally mean we should use two computers - one for live mixing/encoding and one for recording? Can it record locally at the same time? We may want to do post-production on the video files. If it can stream, can it just send the live stream to a computer directly or will I need some kind of BMD shuttle to convert it from HDMI to web-ready format? Can the ATEM do the encoding (much like FMLE) or does it just create H.264 files in real time, therefore meaning we still need to use an encoder like FMLE? We will be using Streamwolf as the platform (much like Livestream, UStream etc) and we have a few software live encoder solutions (FMLE and Streamwolf's own web plugin). We are looking to produce good quality multiple cam live webcasts. I am getting conflicting opinions on the best way to go here and hearing different things about the ATEM Television Studio's abilities.
