Thank you. I have also discovered that video monitors often have this functionality built-in. For example the BlackMagic Video Assist 4K and the Video Devices Pix-E5.

<p>I would like to live-stream from a camera, but replace the audio from the camera with a higher-quality mixed soundtrack, ready for sending over HDMI to a transmission device.</p>

<p>How can I do this?</p>

<p>I know that the Tascam DR-701D has two HDMI ports (in and out). Could I use this as the mixer to replace the soundtrack on the HDMI video feed, ready for transmission, or is there a better way?</p>

<p><strong>Details</strong></p>

<p>The video will come from the micro-HDMI port on the camera.</p>

<p>The audio will come from one of three sources:</p>

<ol>
<li>XLR stream from the event</li>
<li>Directional XLR mic</li>
<li>MP3 player</li>
</ol>

<p>The audio will be mixed together by a mixer during the event as appropriate.</p>

<p>I now need to mix the audio from the sound mixer with the video from the camera’s HMDI port (which will have an unusable poor-quality audio track from the camera). How can I do this?</p>

# Mixing audio with HDMI video to replace the sound from the camera

(Asked by: username_0 on 2018-09-06)

I would like to live-stream from a camera, but replace the audio from the camera with a higher-quality mixed soundtrack, ready for sending over HDMI to a transmission device.

How can I do this?

I know that the Tascam DR-701D has two HDMI ports (in and out). Could I use this as the mixer to replace the soundtrack on the HDMI video feed, ready for transmission, or is there a better way?

**Details**

The video will come from the micro-HDMI port on the camera.

The audio will come from one of three sources:

1. XLR stream from the event
2. Directional XLR mic
3. MP3 player

The audio will be mixed together by a mixer during the event as appropriate.

I now need to mix the audio from the sound mixer with the video from the camera’s HMDI port (which will have an unusable poor-quality audio track from the camera). How can I do this?

It seems that what you are looking for is an **HDMI audio embedder**.

It seems that the Tascam DR-701D offers this functionality as described in [Outputting this unit's audio as the HDMI output audio](https://tascam.jp/downloads/tascam/896/e_dr-701d_rm_vb.pdf)
