Software for multitrack audio and video recording

Postby Mike Senior » Sat Apr 18, 2020 5:32 pm

Hi all,

Hoping this is a quick question, but we'll see... I'm wanting to record a screencast I'm doing on my main PC to a separate laptop, so I don't stress the audio PC with video stuff, and I don't lose the screencast recording if the audio DAW crashes. To that end, I want to capture HDMI video from the screen feed, ADAT/SPDIF digital PCM audio from the DAW software, and balanced mono audio direct from a separate voiceover mic. On the laptop I already have a USB3 capture dongle (which will take the video input) and an audio interface (that'll accept the DAW digital audio and voiceover analogue audio).

So my question is this: is there a simple piece of capture software I can use to simultaneously record all those three signals (HDMI and two audio streams) in real time, in the same way that I might record multiple audio streams into a DAW. In other words. I want them all to record in sync within a single interface, but I don't want the software to mix the DAW and voiceover audio together for recording. Hope that makes sense... I already have video-editing software (Vegas), so I'd rather not invest in a whole new editing platform if possible.

Thanks in advance!

Have you looked at OBS? it should allow you to have as many input devices as you need... I haven't tried with two audio feeds but having multiple video and audio stream is one of its design reasons - e.g. the soundtrack from a game plus commentary from the gamer's mic (and of course both the game screen and a camera with the gamer in PIP).

Replace "gamer" with "guru audio engineer" and there you are. :)

As a question, why not running everything from one machine? A DAW crash shouldn't really be a big deal - modern machines seldom crash in blue screen mode nowadays?

I would have thought that Vegas could do exactly what you want as it started life as a multitrack audio recorder that added video later. However, it depends on whether Vegas supports your capture dongle.

Tried this already, but it seems to consolidate all the input sources into a single output file, rather than keeping them separate

:lol:
Great one!

:roll:
...but seriously, I just trust computers about as far as I can throw them, and have had bluescreens from time to time on every machine I've ever owned, including ones set up specifically for audio by specialist suppliers. And I just want to avoid ever having to redo stuff, especially if its like and hour's work or something. It's really depressing...

Thanks for the tip, though! :)

I tried, but it does its live video recording via a separate 'capture' window, rather than directly from the 'arrange page', as it does with audio. I'm running quite an old version, though, so maybe that's possible in newer updates...

Maybe vMix? https://www.vmix.com/. I haven't used it in exactly the way you are asking about, but it can certainly handle the sources you're talking about and send them to different outputs. There's a demo on the website ...

Looks promising. I'll have a closer look... Thanks for the tip!
