Try without anything Matrox, just a standard Adobe project. That will likely solve it.
I do not recall a lot of issues in CS3, that were specific to Matrox, but CS4 and its updates pointed up tons of issues with Matrox drivers. Matrox had play "catch up" with every iteration of the CS4 updates. However, there almost always seem to be some issue with Matrox and Adobe, so that would be a likely "candidate," as Harm points out. It might not be the correct one, but would be worth a look with a test on a totally non-Matrox Project.
It seems that when everything (and I do mean everything) is set up perfectly at all levels, the Matrox cards work well for many, even with PrPro, but there are just so many, who have little problems in the setup (drivers, etc.) and things go south in a big hurry.
Please report your findings, as they will likely help others.
Thanks for the suggestions guys.
Just to be sure of everything I have;
Uninstalled all of CS3 Suite (used the ScriptClean also) & Matrox Tools.
Reinstalled CS3 Suite, updated CS3... then Reinstalled latest Matrox Tools
After clean installs, I have tried using the sequence file by all of the following methods with results shown;
File>Export>Movie ------ allows settings and encodes
File>Export>Matrox Media Encoder ----- closes Premiere with no message
File>Export>Adobe Media Encoder ----- closes Premiere with no message
File>Export>To Encore ----- brings up 'Export to Encore' but selecting "settings" button closes Premiere with no message... accepting default settings continues and encodes file
Thanks guys for the brain power... I'm puzzled.
Hey Harm... maybe I don't fully understand your suggestion.
If I tried 'File>Export>Movie ------ allows settings and encodes'
'File>Export>Adobe Media Encoder ----- closes Premiere with no message'
is this not eliminating Matrox?
Also, help me here, how do you select/set-up the encoders for 'export to encore' so that I can eliminate Matrox intervention?
Thanks for your patience and help.
Start a project and sequence settings using standard Adobe presets, use standard non-Matrox source material but standard codecs. Then try again.
