ATEM Television Studio: AES/EBU BNC Input from Analog Sound Board?

[Doug Fish]

Camden, good to hear you’ve got it all straightened out. Most frustrating thing is to know what you are doing should work, but you can’t figure out. The last thing you would figure is for the unit to be defective right out of the box.

Mikhail, thanks for increasing the knowledge about what works to bring sound to the ATEM TVS.

Hi Guys.
I’m thinking of pluging a SPDIF ( RCA coaxial cable ) from my audio interface ( M-Audio ) straight to the ATEM TS with a BNC adapter.
I just can’t find the Behringer interface with XLR (AES/EBU ) outputs here in Brazil.

The thing is I heard that many people are experiencing out synched audio.

Does anyone know anything about it?

Doug,

Your recording sample looks smart

You might try the later switcher download v2.8 recently out. It uses different record programme much easier to record from within the switcher window.

This may fix your problem of keeping the sound synchronized when recording

John, I downloaded the 2.8 update last week. The 4-second video to audio delay was an aberration which hasn’t occurred again. Nonetheless, I do get about a 3-4 frame delay in my estimation between the sound and the video. I could fix it, but it’s an acceptable delay–it’s not perceptible to most.

I didn’t do anything to the sync in this week’s video, and I’d like to hear opinions. Do you notice the delay? Would you notice the delay if you weren’t looking for it? See the link below:

Hello Doug,
I looked at your recording. Good, I find the sound very acceptable as there is only 1 frame delay in the ATEM, I know what 4 frames looks like. You have to look very hard to see there is a slight delay that you and I know about. Well done.
How have you found v2.8 to use? My system is still in construction, It will be a mobile unit in the back of my van.

Thanks for the feedback, John. I know I have had to move the audio back 4 frames to get sync in the past, but you’re right, that particular video is barely off sync.

I’ve been using the ATEM TVS to record for about 3 months now, and I haven’t seen much rhyme or reason in the amount of delay that ends up in my video. I’d get a device to delay the audio, but I don’t know how much is necessary on any given Sunday, so I’ll continue to correct if necessary in post. Perhaps with 2.8 there will be some continuity.

Other than that, however, the ATEM TVS has been a wonderful piece of equipment, and very reliable, too. Amazing what $1K will get you these days. Since we began recording in August, I’ve only had one Sunday where we couldn’t deliver a recording of the sermon, and that was before we were even using the ATEM TVS. My camera operator confused the headphone and audio in jacks on the camera, so we didn’t get sound that week. Didn’t notice until the service was over.

Used 2.8 for the first time last week. It is very convenient to record from the software control panel. I believe that’s the extent of what changed from 2.7 to 2.8.

I am just wondering .. how is the latency problem
I know u can put a delayer for recording

but if for live consert … How do we provide
a out of sync video to the TV wall

And how do u guys pull your camera using HDMI
for this Atem

So do 2.8 solve the video delay problem

since audio is from the PA for live consert
and video go ATEM and when it goes to the TV screen will it delay

I am using osprey 460e and vidblaster I have this problem
Out of Sync ..

I think PC SEG is not for Live only record and streaming

Live remote feeds have never been a problem for me in terms of A/V sync. It is in the recording that I have had problems in the past. I will say I have not had any issues with A/V Sync in the recordings over the past month since updating to 2.8.

I can’t say definitively that your A/V sync will be better, as that depends on what the video has to do to get from your camera to the ATEM and then from the ATEM to the video display–any conversion of the signal along the path it travels from camera to display will cause some amount of delay. All things being equal, however, I would say you will be much closer to sync using ATEM than your current Vidblaster setup.

I’m not entirely sure what you mean by “pull your camera using HDMI.” If you mean how do we connect to the camera using HDMI, the cameras I use have a native mini-HDMI output which makes direct connection to the HDMI inputs of the ATEM simple. Remember, any converters you use will add delay, and since you are using the Osprey, I assume you are using analog composite, which would have to be converted to feed into the ATEM. I would recommend trying some cameras with native HDMI out instead.

Here’s our recording from yesterday:

Thanks for your your info
I am glad

The HDMI cable .. can it pull for 100 feet

you Mean your camera in your church to atem is using HDMI
what about atem to projector or TV
what cable do u use..

I am using the ATEM TV Studio but without the audio. I ordered the Behringer SRC-2496 but this is somehow a popular model and wont be available up until September.

My configuration is not using the sound from the ATEM TV Studio and I use a separate 12-input audio mixer instead; which I do have already. The analog audio output is then connected to an audio delay device and then into an Intensity Pro capture card installed on a MacPro. I used the ATEM TV Studio’s HDMI program output as my video source for the Intensity Pro video capture.

The basic configuration on my MacPro only allows NTSC capture so I upgraded my memory to 16GB and that fixed that problem. I can capture in any format now.

My next project would be to purchase the HyperDeck Studio so that I don’t have to drag the heavy MacPro to my location shoot.
