Matrox & Pinnacle both have individual +ve points.
U have to look what suites U.
Matrox solutions is more matrox hardware & less PC &/software dependent
while Pinnacle is 99% software/PC hardware dependent & independent
of any dedicated Video Hardware EXCEPT EDITION PRO which
is actually a VGA card with a AV in/out CHIP to get U
Analog AV in & out only.Other than AV in/out it does not effect
any REALTIME capability.
If U get Liquid Edition U can upgrade your computer & software
& get more features in future becos its 99% software based NLE
So its more scalable than MATROX RTX.
But Matrox does have some cool features which U may need
AT THE MOMENT
like REALTIME SlowMO
RAM Preview in 3rd part applications like AfterEffects & 3D MAX
which PINNACLE EDITION does not have.
But yes Pinnacle Edition is more powerful in LAYERs
U can have more VIDEO & GRAPHICs layers in REAL TIME in Edition
but FIREWIRE OUT IN Edition is not REALTIME while its realtime
Pinnacle Edition is more STABLE rather ROCK SOLID STABLE
& instant responsive for every command
whether U R doing a small or long form PROJECT.
While Premier(i tested 6.x/5.x) gets slower & slower
as your project gets bigger & bigger.
INTERFACE of Pinnacle EDITION is more EASY
as compared to PREMIER PRO.
if U want PREVIEW in 3rd part apps like AfterEffects & 3D S MAX
then there is not other choice except MATROX RTX or canopus DV STORM.
So Narrow down your requirments & then choose the product.
I personaly would go for a VIDEO TOASTER hardware
& other than that would go for Pinnacle LIQUID EDITION software only
& Adobe Premier PRO software only.
Becos the MOST POWER FUL hardware software combination
at the moment is Newtek VIDEO TOASTER VT3
where there is no boundry to your requirment
& Newtek never SAYS no to any feature u want in Videotoaster.
since its a record that NEWTEK VIDEO TOASTER is only hardware
in video industry which has been never OBSOLETE rather
just kept on hardware & softwareADD ON s & ADD ons which
increased its features to an incredible level.
So in my RESEARCH.
PRemier PRO & PINNACLE LIQUID edition R EXCELLENT softwares
to work with & NEWTEK VIDEO TOASTER is the best HARDWARE I have every found with EVER INCREASING REAL unlimited features & lifetime
