ATEM 1 & HyperDeck Studio –> Audio Delay

[Carlos Morales]

The video is running faster than audio. Strange. I have found tons of solutions to slow down the audio, but that will not work for us. The audio is already running too slow.

We are running the latest stable firmware on both the ATEM 1 and on the HyperDeck Studio (not the beta).

To fix it, we can bring it into Premiere and move the audio track ahead by 6 frames in post. But this fix does not help us in a live/real-time scenario.

Well,

then I think your camera produces the delay because the Atem only has 1 frame of latency when using non genlocked cameras.

You can try that by using two monitors:

1st monitor (or Ipad or similar) displays a running timecode.
2nd monitor is connected to your camera via the prefeered interface (in this situation HD-SDI). It displays the camera signal.

Record in camera both monitors framed.

Play back you video. Now you can see the latency. Actually you have to include some monitor latency in this setup as well but you get an idea on how much your camera delays the output of the video. I’ve cameras that produce 1 frame and others that produce 3 frames. So maybe the AF100 produces 5 frames (+1 Atem).

Maybe other users of the AF100 could chime in and answer that question.

Hi All,

We have 6 AF101’s (PAL version of the AF100) and there is a video delay of approx 3 frames. I know this is a huge delay but luckily for us we have 6 so we have no issue’s except we have to insert a delay between the mixer and the recorder.

But it is a video delay on the AF101, not an audio delay.

By the way the AF101 is not the right tool at all for multicamera jobs but hindsight is 20/20 and thats not what the were mainly bought for.

Thank you all!!! Based on everyone feedback I was able to solve the problem. I took the audio from wireless mic and fed it into the camera and then took the video and audio feed from the camera to the ATEM 1. The end result is dead-on accurate.
