CANNOT EXPORT MEDIA from Premiere CS4

I'm working on a trial version of Premiere Pro CS4 and it's been great till I got to exporting the project! The encoder opens, no problem but it only encodes one clip. Any suggestions?

Seems to bea vista problem ???
Can't get it working on my Vista PC (not even by installing a new user ...)
But it works on my XP SP3 machine.

I made a shortcut on my desktop to the preference folders.
If one of the Applications don't export, I can easely access the preference files and delete them.
The bad side of doiing this is you lose all export presets.

This CS4 issue with media encoder seems indeed caused by files/preferences of earlier versions. But just re-install CS4 did not work for me:

first try: Remove all CS3, install CS4 >> media encoder failed.
second try: Remove all CS3 with preference folders, registry; install CS4 >> media encoder failed.
third try: Make a new user account in Vista and run under this account >> worked!!!

So, in my case media encoder still tries to use some old settings/preferences and cannot run a new timeline. (It basically cannot handle the prempro project file.) I now kept the new user account and threw away the old one; I couldn't find which settings confused the encoder.... It works now. (thanks for pointing into that direction Menno)

I am again very surprised how unstable Adobe made this product. I had similar issues in the past; esp. with Vista. Maybe Microsoft is to blame too, but other video products seem to be tested better or are far less fragile. Luckily I had just a trial version which I will remove again; not worth spending so much money on.
Also surprising to see that Adobe has no official fix although this issue has been on the internet for months. And it's a serious issue. It basically makes prempro useless.
(and it's a pity, because I really like the product, when it works....)

ok after some speed digging i found a solution :-)

here is is and I hop it helps for you too Wes..

He he I noticed later that this was the premiere forum.

BUT the issues are the same.. No export from premiere eighter!
The media encoder will hang Premiere.

I reinstalled CS3 and still not working!

WTF? It seems that I have to reinstall my whole system??
I dont have time for this. :-(((

Perhaps you want the AE forum?

I have the same issues with After Effects CS4 on Vista x64. It started with AE CS3 where I had to render a sequence. It failed (won't start).
After that EA CS3 AND CS4 won't render anything anymore. Even a simple timeline with a tiff sequence. The media encoder window will come up, but when choosing "quicktime" or "windows media" AE CS4 locks up.

Currently unstalled CS4 and CS3 and reinstalling both... hope it helps.

Thanks Jamiehurt that worked for now!!!

Hello,
I'm on a Mac running a clean install of Adobe CS4 Master Collection - and I have the same behaviour from Adobe Media Encoder CS4 refusing to render/compress any clips from Adobe Premiere Pro CS4.

It puts the "source file" in a temp folder -and the error log says "Could not read from the source. Please check if it has moved or been deleted."

During my troubleshooting I've restarted the machine, moved the cache file, output files and changed caching preferences. I've fixed "permissions" on the Start up disk (a Mac-only phenomenon)

No luck.
I don't have and have never installed CS3 on this system - so it doesn't have that "uninstall CS3 issue."

I DID, however, run an update from Adobe that seems to correspond with this issue. The Encoder worked before anyhow. My current version of Premiere is 4.0.1, Media Encoder is 4.0.0 from the OS, but shows 4.0.1.078 in the "About" dialog box.

The Adobe Updater claimed that this 4.0.1 update would fix issues with the Media Encoder - I didn't give it much thought until now.

-- WORK AROUND ANSWER --
Since I don't have a lot of time to beta test the Adobe Software, here's what I did to work around the stubborn issue today. Open up your Premiere Sequence in Adobe After Effects CS4 and use it's Render Que instead. -- For the most part, it looks like this will solve my issue for today. Be sure to check your work. Audio levels, transitions, Title/CG effects might get all whopper-jawed from this backdoor approach.

Fortunately, the project I have to output today is a simple video edit.
