We're trying to replace a very old TriCaster with VMix. Currently we have three Sony BRC-300 ptz cameras which we have been recording via the TriCaster.

Vmix would allow us to add an HD camera or replace the Sony cameras as we could.

The system is set up using a hex core AMD processor with a ssd operating system drive and 1T storage drive along with 16G ram. We first tried to use the system this Sunday (20, Jan) and had several crashes in a row which we think are attributed to using the desktop capture on one input. The vmix computer is connected to a gigabit network and we get very good looking screen capture of our presentation computer, but we can't deal with mid service crashes,

How can we trouble shoot the crashes? Is there any solution to keep the desktop capture working?

We have three BlackMagic Intensity Pro cards and we are using S-video inputs with our three ptz cameras. Right now we are using the basic HD version of vmix, but I certainly can't see upgrading to the pro version I'd the software won't remain stable with only four inputs.

We're also experiencing progressive audio latency while using the system to record. What can we do to troubleshoot the audio latency?

Can you help?

Thank you.

I had another operator running the machine. He says one crash completely shut the machine down and it restarted. The other crashes just booted him out of the program without error messages. He says he had widows crash error message with a request to debug the program.

The operator says as soon as he shut down the desktop capture Vmix didn't crash again.

We were capturing from a iMac computer running ProPresenter 5, so we were capturing the secondary display of the imac presentation computer.

We want to record our services to post to Vimeo. As a possible feature request is there any way to record to mp4 H.264?

Thank you

Hi Jeremy,

What graphics card do you have in the machine?
System crashes are generally caused by either faulty hardware or buggy drivers, so I would make sure you have the latest drivers for everything
as well.

Jeremy,
It's most likely a band width issue. You should avoid recording to the system drive and use a separate drive or a stripped set of drives would be better depending on the bit rate you are recording. You can use the BlackMagic speed disk utility to check this. The utility will tell what a drive or drives is capable of handling.

I personally never use AMD based machines Only Intel and Nvidia for graphics. I do have a lot of experience building these systems. You can see them at www.streambreeze.com

Update

I made some bios changes and settings changes to V-mix and was able to successfully record about 1.5 hours of sermons and worship today while screen capturing our graphics computer output as another input on Vmix. I set memory speed to 1333MHz, and processor speed settings to default. I also changed the WMD codec to wmv1. It was wmv3 and would crash when trying to record three sd cameras and the screen capture input.

A big win for me is being able to upload the capture directly to Vimeo after service. With TrICaster I had to convert the recorded file from NT25 codec to a more generic avi, then "un stretch" the 4:3 output to 16:9 and convert to mp4 for upload to Vimeo. Because the old Tricaster is a Pentium4 computer, munching on 40Gig avi files consumed much time and space. It took me roughly six hours each Sunday afternoon to Prepare for VCR and then unstretch and convert to mp4. I would log into the TriCaster remotely using splashtop to start the tasks and check in later to see if they were done and finally upload to Vimeo.

Also, with Vmix, I'm hoping to use a HD camera as one input to further increase the quality of our videos.

I do need some help getting audio from our sound board into the Intensity Pro capture cards. Presently I use the line in of the computer, but that seems wrong; shouldn't I be able to use a capture card audio input along with the video input?

As there is no editing capability in vmix I'm trying to fade in and out of my show using vmix. How may I do that?

I used one input of the basic HD vmix software for screen capture. Our presentation computer feeds a Matrox TripleHead2Go and we use two-wide output, so I have to crop and pan the screen capture input to show only one screen of the presentation computer, I don't mind this so much, but it would be nice if the vmix preset saved the crop and pan settings and the secondary monitor input settings. Is there a way to do that?

I'm looking forward to stablizing the system with vmix pro and figuring out how to multicord for post editing if we choose. I'll see if there is a 6Gbps sata port on the motherboard and look into a raid array for multicord. But this Sunday was a success for us...
