GoPro 4 with ATEM Switcher - Not Recognized 1080p

PostThu Oct 23, 2014 10:43 pm

Hey Guys,

Having an issue with the gopro 4 working with the ATEM switcher @1080p, currently the only settings that work are the ATEM at 720 59.95 with a gopro setting 720 @120fps and unfortunately none of my other cameras work at those settings.

Still on the older switching software, anyone try this with the firmware upgrade? For now I am going to stick with the GP3 and my other cameras until we can find a solution.

Thanks!

Which ATEM switcher do you have? The Television Studio and original ATEM 1 M/E and 2 M/E didn't support 1080p60 (only 1080i60). It's possible that the GoPro 4 is outputting 1080p out of its HDMI port.

The newer ATEM 4K models should support 1080p.

Are you connecting the GoPro directly to the ATEM via HDMI or are you going through an HDMI to SDI converter (and SDI input into the ATEM switcher)?

I have the ATEM Television Studio and had tested the GoPro 4 on the ATEM 4k with no success for any of the input settings. I have also tried both direct connection and input via the 4k and battery powered hdmi to sdi converter.

I know for previous gopros there is a workflow to follow however this new one doesn't follow the same pattern.

For your reference, the following link shows you the tech specs for the ATEM TVS and the supported resolutions for it.

I don't have a GoPro 4, but my experience with the GoPro 3 was the following:
  • Setting the GoPro to 720p120 seemed to get it to output a 720p60 signal over its HDMI port
  • Setting the GoPro to 1080p60 (or 1080p30) would cause it to output either a valid 1080i60 signal or a messed up 1080p60 signal out of its HDMI port (depending on the device it is connected to)
I believe this is because there is some negotiation that happens with the HDMI output. So if the receiving device only says it supports 1080i, then that is what the GoPro will output. For example if I connect the GoPro directly over HDMI to the ATEM Television Studio (which only supports 1080i) this seems to cause the GoPro to send a 1080i signal which shows up fine on the ATEM.

If instead I connect the GoPro to one of the HDMI to SDI Battery Converters (or HDMI to SDI 4K Mini Converter) both of which support 1080p60, then the GoPro will output a 1080p60 signal over HDMI. The HDMI to SDI Converters then output a 1080p60 signal over their SDI outputs (3G SDI). On an ATEM TVS (which doesn't support 3G SDI) or an ATEM 4K set to 1080i mode, it will not see this 1080p signal.

Furthermore, this 1080p60 signal output by the GoPro seems to be messed up in some way, and even connected to a device that supports 1080p like an ATEM 4K (set to 1080p60), I get a flickering/intermittent signal (or sometimes no signal at all).

Some people have used a device like the Gefen HDMI Detective inserted between the GoPro and the target device to force the GoPro to output 1080i or whatever the desired format is. I don't have a GoPro 4 yet, so it's possible that its HDMI output is different, but at least with the GoPro 3, the best advice was getting things working was usually:
  • Use 720p if you can (setting the GoPro to 720p @ 120fps for NTSC or 720p @ 100fps for PAL)
  • If you need 1080 resolution, connect the GoPro to a device that will force it to output 1080i
If you have both a GoPro 3 and GoPro 4 it would be awesome if you could try the different configurations with both cameras and report back what works in each case (720p60, 1080i60, 1080p60).

Gopro3 1080i...

I've had success using the Aja ha5 hdmi to sdi converter (doesn't support 1080p), and using an hdmi detective between the gopro and the BMD hdmi to sdi battery converter. Seems like I remember any recording frame rate at 1080 on the gopro worked to produce video out the ATEM would accept with these devices.

I have no purchased a gopro4 yet, sorry...

GoPro 4 does not work with the 720p work around.

I have been borrowing a GP3 because of this. Please send a solution only if you have worked with a gopro 4 and figured out a solution for a 1080 ATEM setting.

Thanks!

I can confirm as well that the Go Pro 4 silver addition does not work with the ATEM TV even just connecting it directly with a 3 foot micro hdmi cable which is odd seeing the Go Pro 3 black works with a direct hdmi connection to the ATEM. I run the 3+ black edition into a AJA HDMI to SDI converter and it works great though it took me 4 trips to B&H to finally get the right setup. I wanted to add one more go pro to my ATEM setup which is 3 Sony ex 1s via SDI, the go pro 3 black via Aja sdi converter, and I thought for sure the 4 would work but it doesn't on any setting, so I am returning it and getting another 3 black, which sucks :| go pro tech-support say they are not made for use with live broadcasting, well obviously a lot of people want and do use them for broadcasting so why don't they freaking make one for broadcasting and up the price ladies and gentlemen introducing the new Go Pro Pro addition!!. It's a shame because the 4s quality is s step up from the 3. I only have two open hdmi ports on my switcher, I tested the hero 3 black yesterday running it hdmi into Aja out sdi into another Aja sdi to hdmi then into the hdmi port on the ATEM and it works. I first tried this with the new 4 silver and actually got some signal but it was all screwed up. But direct hdmi I get know signal at all. Plugging the 4 into an hdmi tv it says the signal is 1080p 60hz which is the same thing my nikon d5200 says and the nikon works with the switcher as well. Everything I plug into the switcher works except the Go Pro 4. I know there is another sdi to hdmi converter that has dip switches on it and perhaps that might work but I am done running to B&H it is not made by black magic or AjA but the name starts with an A as well. It might be able to convert the go pro 4s signal from 1080p to 1080i but I give up and will stick with the 3 black.

If you're looking for a GoPro alternative for live usage, you might want to check out the Marshall CV500-MB2 (http://www.marshall-usa.com/optical/cam ... 500-M2.php).

It has a built in SDI port (so no need for an HDMI to SDI converter) and supports true 1080i5994 output. Size of the camera is actually a little smaller than the GoPro and video quality seems comparable (at least at 1080 resolution). Pricing is about the same as the GoPro as well. Even supports interchangeable lenses (M12 mount).

Main downside is that there is no internal recording (no micro SD card slot as on the GoPro), so it's strictly for live use. Also lacks the GoPro's 4K and high frame rate 720p modes, but these seem less useful for live usage anyway.

Ive successfully connected my GoPro Hero 4 Black to the Atem Production studio 4K at full resolution

Heres what i did.

The HDMI/SDI converter i used is the Decimator MD-HX It is a wonderful piece of equipment. it is also a scaler which allowed me to get things working right.

If you want to convert to SDI set the ATEM to 1080i 59.94 mode
set the decimator to 1080i
set the GoPro to 1080S 30FPS

Thank you for the hint on the Decimator, Miguel! That's a huge find. I looked it up & it's even cheaper than some of the newer BMD converters. Maybe BMD will learn from it. We were able to rent a couple from a local distributor & will be testing them out for a live production environment with GoPro 3 blacks. THANK YOU!

I own 3 decimators and they are the best...very versatile and best bang for the buck!

The last post in this thread is about one year ago. So maybe there is some changes. Also my use case is about ATEM Television studio.

Configuration of my planned use case:

[1] ATEM Television Studio
[2] 2 x GoPro HERO4 Silver Edition cameras

Would the above system work flawlessly at 1080p ?

Will ATEM TV Studio be able to read in audio also which comes from GoPro?
(I read somewhere, some HDMI-converters may have problems with GoPro's compressed audio in HDMI.)

The ATEM TVS does not accept 1080p signals. The Tech Spec page for the TVS gives you the information as to which formats it supports exactly.

It was not quite clear.
It says:
HDMI Input Resolutions for Computers
720 x 480 59.94Hz,
720 x 576 50Hz,
1280 x 720 59.94Hz 50Hz and
1920 x 1080 59.94Hz 50Hz.


there is no "i", nor "p" in those.

And then there is:
HD Format Support

720p50, 59.94
1080i50, 59.94


I think to be clear, there should be "p" in the first line, and "i" in the second line of "59.64" (but there it can be assumed)

The camera setup is what we're addressing as this is the most common input to our switchers and that information is listed on the format support you see on the tech spec page. Cameras don't list their output in Hz but in fps as you see mentioned in the format support.

The reason for the computer resolutions is that there are some supported resolutions for computers to use to ingest into the switcher and they are limited to the ones mentioned in that area.
