HI there, brand new..just downloaded the software for a trial.
My main question is can you record 4 HD-SDI inputs at once in multicorder
mode using the Decklink quad? In other words, hit one record button
and start recording 4 clips in sync..? Or does multicorder
only let you switch between four inputs while recording?

Also, has anyone tried (2) Decklink Quad cards for (8)
simultaneous HD-SDI record clips at once? Of course on a screaming system
THanks

Hi Matthew,

Welcome to the vMix forums.
Multicorder is designed to record multiple selected inputs.
These inputs cannot be changed 'on the fly' or during recording, AFAIK.
BUT THAT WOULD BE A VERY DESIRABLE FEATURE!
(I'm only shouting and writing in blood because my previous post on the subject remains unanswered)
I shoot live music events in 50mbps HD with 6 cameras and I'm pretty sure even vMix, as amazing as it is, could not record 7 such streams on current affordable hardware.
Even if it could I wouldn't want to carry the disk array.
But a back-up shot, or shots, is essential to correct mistakes or to improve the mix.
If vMix could record even one back-up stream, or "alternative mix", it would make an old man very happy, and quite a few young 'uns too, I suspect.

Brian, thank you for the response.
Still unclear here however, my apologies for any confusion..
My question is :
Does Vmix allow you to record 4 individual clips SIMULTANEOUSLY, each coming
from a separate input, by simply hitting the "record" button one time.

I want to record a live event from 4 (or more ) cameras and then
edit those 4 angles (recorded clips) later on an edit system.

THank you
Matthew

best bet would be to record on the cams themselves no ?

I almost forgot: and you can use this to re-sync your clips:

Hi Matthew,

I don't have vMix Multicorder but, as I understand it, you can record 4 separate inputs to four clips simultaneously.
Subject to PC spec, of course, or number and speed of hard disks, or SSDs more likely.
The "trigger" control is likely to be similar to the record option, which is not simply a button to hit, as I'm sure you have discovered.

Hi Luc,

Recording to cameras is certainly an option and a sensible back-up back-up plan ........ BUT .......

1) my cameras cannot record at 50 mbps MPEG so there would be a drop in quality.

2) access to cameras to change tape or cards is not always possible except between music sets.

Thanks for the link to pluraleyes. I've heard of it, and had always meant to try it, but old habits die hard .... old dogs etc.
I rely on the time-tested method of lining up the audio. I can hear 2 frames difference on most audio, then just slide it back and forth until I give up trying to "see" the difference. It doesn't take long ;-)

Brian
