Is there a way to combine an audio source with an existing video source over SDI

Not sure what you mean but for example the Intensity Pro capture card shipped with a breakoutcable with analog in and output.

So with that card one way is to input the audio to the analog inputs and output the combined audio and video over the hdmi output.

There are cheap converters for sdi to hdmi and the other way around and audio de embedders. So you can for example output hdmi in to a hdmi to sdi converter.

The new Atem Mini has two stereo mic/line inputs thatvyou can hook up an unbalanced mixer to if you need to input multiple audio streams to hdmi.

So there are even a few pretty cheap ways of getting analog audio to a hdmi stream and sending it a long way.

Expensive ones I guess there are tons of but I have been doing amateur music recording for ever so I use the gear I already own.

Thank you for the input, I have a church that has a SDI video source going to a TV with a SDI to HDMI converter connected to the TV. They want to combine an audio source coming from the board to the same SDI cable to get audio along with the video on the TV. Im wondering if this is possible and what do you suggest equipment wise to make that happen if at all possible
