Hi everyone,
have been a long time reader of this forum as unregistered user. We use vMix in our company in so many different ways and we are always trying to do even more... and we encountered an issue today.

We are trying to record via vMix a multichannel file in .ts format: first of all is it possible?

Here's the setup and the idea behind it: we want to feed into vMix an SDI signal via Decklink 1 embedded with 4 separated audio channels, that needs to stay separated trough all the process; we then want to record a multichannel .ts file for a delayed playback in the same vMix instance, outputting that as multilayered SDI signal via Decklink 2. Essentially, vMix will serve as a delay on our brodcast. We then feed the external output to a different computer where different webstreams are made, one for every audio layer.

We already successfully tested the playback-while-recording thing on the video .ts files, but the issue is that vMix appear to "flatten" our 4 audio channels into a simple stereo video file, loosing the multichannel aspect of it.

Hope i've been clear enough and i thank you in advance for your attention and, hopefully, help.

Cheers! :)

Thank you! I'll +1 that.
