![]() ![]() ![]() If the ATEM mini could output a 720p 30fps stream over usb to a computer, then a lot of us could have avoided buying a whole new computer just to handle what the ATEM mini could do. Unfortunately the value of offloading the video processing vanishes if your computer needs to re-encode the stream in order to use it. You don't need software like EEcam, and you can use much nicer cameras. This delay is entirely because the computer can't keep up with the encoding.Ĭhoosing to use a device like the ATEM mini means you get to offload most if not all of the video processing from your computer. Both of these systems lag horribly, and participants see video on "satellite delay" while the audio comes through on time when using the ATEM mini as a webcam source. For instance, Zoom manages this trick with 120% CPU usage, while MS Teams uses 280% on my older MacBook Pro. This can put a huge CPU load on the host system.Īdditionally, not all software is equal. ![]() It is important to note however, that the way many support 1080p, is often to down convert it to 720p on the presenter's computer prior to uploading the stream. Yes, some of them support 1080p, that is not in dispute. has native support for 720p for participants, primarily because that is what resolution camera is built into nearly every laptop today. Nearly every video conferencing application that I have to use (and no I don't always get to choose), Skype, Zoom, MS Teams, WebEx, GoToMeeting, Join Me, Google Meet, etc. I use the ATEM mini Pro for video conferencing and presenting, and out of the box it does exactly what I need as a presenter, but is on the border of bing un-useable for live streaming. The use case here is simple, and has nothing to do with whether or not 1080p at various framerates and bitrates are better or even supported by one platform or another. I'd also like to put a vote in for 720p output over USB when connected to a computer (if it is even possible given the chipsets within the device). It's frustrating that OBS gives options all the way down to SD but the Mini Pro does not. The whole purpose of trading our ATEM Mini for the Pro model was to use the built-in encoder and bypass OBS. Since the Mini Pro already has multiple encode quality options and frame rates, is it possible to write a script to create a "baseline" quality option? Forgive my ignorance - I'm a producer and not an engineer, so I'm not educated on how this works. What I think the OP is getting at, and I want the same thing, is the ability to output the encoded stream directly from the Mini Pro at 720 / 30fps / 2000Kbps (I think YouTube Live gives error messages when the signal is less than 2000Kbps). OBS can downgrade the signal to 720 / 30fps / 2000Kbps, but as anyone who has used OBS with a newer MacBook knows, it's a horrible experience. I'm in a similar situation, where I am now streaming weekly from my church during the COVID pandemic, and the internet signal from their ISP is unreliable and often insufficient to support even the "low" (3500/Kbps) stream setting from the ATEM Mini Pro.Īt the moment, we're bringing the signal over to my MacBook Pro via USB-C and encoding the stream with OBS. ![]() Please let me know if I've missed a setting in the ATEM control software or if I can use some method to constrain my stream output to 720p/30. The cost is about the same, however without the ability to downscale the stream resolution the ATEM is a downgrade in capabilities for my use-case and will be left at home instead of providing me the more reliable and efficient mobile stream studio that I was hoping to achieve. The Mini Pro is a great product and it helps me get twice the battery life out of my mobile backpack than what I could achieve with an Intel i5 NUC. Creating a custom streaming profile does not reduce the frame rate or resolution as I expected. However it appears that the stream output selects the highest frame rate and resolution provided to the device. In the product specs I saw that the ATEM Mini Pro is able to scale the camera output as needed. In order to keep up with a moving shot this means that I cannot shoot 60 fps full HD. In many situations I do not have funds for a Live-U or despite having that device the network connection is poor enough that I would like to stream at a rate as low as 1 to 1.5mbps.
