TriCaster VT[5] Troubleshooting Third Party Products

Why do I not see my Mirage frame buffer output?

Q: After installing Mirage 1.5a and VT 4.6, VT is no longer an input/output option in the Video Grabber panel in Mirage so I see no output on the VT's buffer. Also, Mirage doesn't appear on VT's switcher panel. Why?

A: You must do a Custom Install of Mirage, and select the VT as its frame buffer.

Why do I get an error message, Vafxu.dll is missing?

After launching VT or any other app that does Quicktime, if you get an error that Vafxu.dll is missing, then at some point you likely had a Pinnacle/Avid product on your system but uninstalled it.

Go to C:\Program Files\QuickTime\QTComponents and delete all the Fast files from there. There may be other names, but it should be obvious and they were the only ones in there.

I can play divx files back in VT-Edit and DDr, but I seem unable to render out to DivX files; why?

That is because DivX is not a real-time capture process. It is a 2-pass record, which precludes working under VTs real-time expectation.

Can I use MXF in VT[4]? If so, how?

Reading an MXF file:

  • Drag the file into VT-Edit. This should support DV and MPEG2 (note that VT comes with a MPEG2 decoder plugin as part of DVD WS, so we should read MPEG2 MXF files as well.)

Writing an MXF file:

We only support DV MXF files directly from VT-Edit. If you need MPEG2, they you need to go via DVD WS.

  • Write a DV Type 1 AVi file from VT-Edit
  • Wrap this file using the Snell & Wilkox MXF wrapper.

I re-loaded an older project into VT and all my transitions are now at 4 seconds; why?

It is because you used some of the Hat Tricks DVEs in your project. You can easily set them back by using:

Tool Shed > DVEs > Adjust DVE

Can VT[4] help me with my After Effects projects?


NewTek provides a plug-in for Adobe After Effects support. This plug-in has two components: one provides After Effects read/write support for NewTeks uncompressed .rtv file format with alpha channel support. The other allows you to work in AE and benefit from the VT[4] hardware frame-buffer output to your video monitor.

NOTE: The directory structure of AE was changed by Adobe after NewTek provided this support, so if you are using After Effects version 7 or later, you must manually move the following files to the following locations:


C:Program Files >Adobe > Adobe After Effects 7.0 > Support Files > Plug-ins > Standard > Standard Effects


C:Program Files > Adobe > Adobe After Effects 7.0 > Support Files > Plug-ins > Standard >Format

To have RTV file support in a computer without VT[4]:

Copy the RTVIO.aex plugin file to:

C:Program Files > Adobe > Adobe After Effects 7.0 > Support Files > Plug-ins > Standard > Format

Copy the RTVlib2.dll file to:

C:Program Files > Adobe > Adobe After Effects 7.0 > Support Files

This will then allow After Effects to import and export NewTeks RTV uncompressed video format.

I just upgraded my system to VT[4], but now I cannot load my previous projects. What's happening?

If you have used any of the Bob fx plug-ins, that is your problem; contact Bob fx for their revised code, which makes your projects compatible with VT[4].

Why do I get a VTNTAPl.dll error when I start VT?
