Important Matrox Info - v5.0 public beta drivers for CS5, Aug '10

Matrox has released a public beta of the drivers which will support the RT.X2 under Adobe's CS5 version of Premiere Pro. Whilst they are useful for adding support to CS5 for the playback of Matrox AVIs containing HDV video (which requires the Matrox hardware for decoding), the drivers are far from bug-free and should not be considered to be "production-ready". They definite reduce the stability of CS5, and have various field-order issues with PAL SD video.

v4.2 drivers released, Jan '10

Windows 7 is now with us, along with Premiere Pro CS4.2, and as usual this requires a new driver from Matrox to support their cards. The good news is that Matrox have now released new 4.2 drivers via their web site. These drivers are designed to work with Adobe's recently released 4.2 & 4.21 updates to Premiere Pro CS4, which you should not install until you can install the Matrox 4.2 drivers at the same time.

Earlier in 2009, the Adobe Premiere Pro CS4 4.1.0 update introduced major issues with Axio and RT.X2 systems if you updated to it from v4.0 without updating your Matrox drivers at the same time. Matrox has v4.1 drivers that support the Adobe 4.1 update, and which can be downloaded from the Matrox web site.

If you have already installed the Adobe Premiere Pro CS4 4.1.0 update without the new Matrox drivers, you will loose transparency when using Matrox effects or videos containing alpha. You will also experience instabilities when using the Matrox chroma key and during rendering. If you wish to revert back to Adobe Premiere Pro CS4 4.0.1, you must first uninstall Matrox Mx.tools or Axio.utils and Adobe Premiere Pro CS4 4.1.0. Once the Matrox and Adobe software has been removed, re-install Adobe Premiere Pro CS4 4.0 and then re-install the Adobe Premiere Pro CS4 4.0.1 update which is still available on the Adobe website. After the Adobe software is re-installed, re-install Matrox Mx.tools or Axio.utils.

         V4.0 RT.X2 drivers are for Premiere Pro CS4.01 only

Matrox RT.X2 release 4.2 is now available from the Matrox website, explicitly for the 4.2/4.21 versions of Premiere CS4.

  • Matrox v4.0 drivers support Adobe Premiere Pro CS4, version 4.0.1 (earlier versions of Adobe Premiere Pro are not supported). Both 4.0 & 4.1 versions include the following new features:-

  • Support for the 64-bit version of Microsoft Windows Vista Business or Ultimate allows users to break the memory limitations of 32-bit operating systems and install more than 4 GB of RAM on their system for improved stability and performance. Vista 64-bit also breaks the 2 terabyte disk-size limitation which exists in 32-bit operating systems. Microsoft Windows XP Professional, Windows Vista Business, and Windows Vista Ultimate (32-bit versions) are also supported.

  • New DVI monitor calibration utility that turns your DVI monitor into a true-color video display for use with SD and HD video. Controls for hue, chroma, contrast, brightness, and blue-only let you adjust and control your DVI monitor exactly as you would a broadcast HD/SD video monitor. (Not applicable to RT.X2 LE or RT.X2 SD.)

  • WYSIWYG support for Adobe Encore CS4 that lets you preview video played back from the timeline on your video monitor by setting the player for your project to Matrox Player (available on the Advanced page of the Project Settings dialog box).

Please note that in order to offer CS4 and Vista 64-bit support as quickly as possible, there is no support for Matrox accelerated exports in v4.0, and some support in v4.1 (for Matrox AVIs). Otherwise, exports are only supported in VFW mode. These Matrox accelerated exports are available via a custom Tab in the Media Export settings when running the v4.1 drivers. This export will be performed in a modal fashion (like in CS3) so users save the setup time and disk space required to run the Adobe Media Encoder. However, they will have to wait for the export to complete in order to continue working.

Matrox Axio v4 drivers now available too, with similar support for Adobe CS4.01 and new video file formats like XDCAM HD 422

Extras for use with RT.X10/100 & RT2000/2500 & Premiere

Magewell have cancelled their travel plans to ISE and we will be helping to man their booth - number G475 in Hall 8.

As a result, the ZEN office in Salford will be closed from 1pm Monday 11th and
open again on Monday 17th February. During this period, email response may be
slower than normal, and no outbound shipments will be made.

What we're about . . .      ZEN is not a traditional Audio-Visual dealer who started selling computers, nor is it a computer shop that also sells video products. You won't get any salesmen giving you the "hard-sell" when you call, just straightforward advice and information - which for some callers is the knowledge that they don't need to buy whatever it is they thought they needed! Above all you'll be dealing with someone with a wide range of experience and knowledge of both PCs and video production. We're not the biggest, nor necessarily the cheapest, but we are one of the longest established computer/video specialists in the UK.

Company history . . .      ZEN was started in the 1980s by Martin Kay, then working for ITV at Granada's Manchester studios, who built his first 6502-based computer in 1979 from an Ohio Scientific kit, bought in the USA whilst working as a Sound Recordist on a film shoot for World In Action. With the advent of the Amiga, which could be gen-locked to a video source, Martin started writing a variety of video-related software. This included subtitling & tele-prompting, ident clocks, scoring software for sports & gameshows, and specialist software to mimic other computer displays for use in TV film dramas like Cracker, Prime Suspect and A Touch of Frost. Martin left Granada in 1993 to concentrate on his computer-video activities with ZEN, following a natural path into non-linear editing systems, for many years the main business activity, although he still maintains an active interest in video production.
