That seems to be a recurring issue with dual-core and nVidia setups, especially "new" machines and Vista (you didn't say your OS, but I'll bet Vista...). One quick and cheap possibility that worked for me with the exact same issue: reboot to CMOS, look for "Plug and Play" and change the toggle from "OS" to "BIOS" (or, if already set for BIOS, change to OS), reboot and try again.
I have no clue whatsoever why that works, but I tested it back and forth: if Plug and Play is set to OS, no video. If set to BIOS, video.
Thanks for theissue, but it didn't worked for me :(. As you said, I'm using Windows Vista x64.
I searched a long time on google and I don't thing that my computer's resource are the cause of my problem. However, I found the Sherlock utility that scans all the codecs installed on the computer. Here what it said to me:
1. "MainConcept (Adobe2) AAC Decoder ("C:\Program Files (x86)\Adobe\Adobe Premiere Pro CS4\ad2daac.ax")
2. "MainConcept (Adobe2) MPEG Audio Encoder" ("C:\Program Files (x86)\Adobe\Adobe Premiere Pro CS4\ad2mceampeg.ax")
1. "MainConcept (Adobe2) H.264/AVC Decoder" ("C:\Program Files (x86)\Adobe\Adobe Premiere Pro CS4\ad2dsh264.ax")
2. "MainConcept (Adobe2) H.264/AVC Video Encoder" ("C:\Program Files (x86)\Adobe\Adobe Premiere Pro CS4\ad2evh264.ax")
3. "MainConcept (Adobe2) MPEG Video Encoder" ("C:\Program Files (x86)\Adobe\Adobe Premiere Pro CS4\ad2mcevmpeg.ax")
After, it tells me that the driver file for the codec was not found.
I tried to download the codec, but it did not worked.
I can try to reinstall Premiere, but it takes a lot of time...
Do you have an idea?
Sherlock is providing a false error. The error results from these codecs being added in the Windows registry with quote marks around them - the usual for such things is no quote marks. This does not create any functional problem with the codecs. You will see that Sherlock is saying that the file is not found (and it is looking for a name in quotes). Note that the codec list available in GSpot reports the same false error.
One of the original messages I posted on this is no longer available (in the Encore forum changes), so I am restating the details here. My guess has been that this registry style was introduced in CS3 (it does not occur in CS2), and based on your results appears to still be true in CS4.
The location of the correct codecs is in the main directory for each program (e.g. PPro CS3, Encore CS3, each has each codec they need in their directory - for me c:\program files\adobe\adobe premiere pro cs3 etc.). I think someone once confirmed my suspicion that adobe is not looking at the Directshow merit ratings for the encoder to use. I really don't know.
The "DirectShow Filter Utility" lists these codecs out of alphabetical order (due to the quote marks), but correctly indicates that they are installed. Be careful, it allows you to change things!
When I reported this about April 2008, I found no references to this in the forums or the adobe support searches, and only one reference elsewhere, so I entered a bug report. Because it does not impair functionality, I do not believe it is classed as a "known issue."
Are those the only codecs it found on your whole machine? By the way, I find that Sherlock always tells me that the Main Concept codecs have no drivers.
Were you able to see video on your computer prior to the installation of CS4?
I have many others codecs that are installed but Sherlock only tells me that Main Concept codecs are not properly installed.
I had Master Collection CS3 last week and it used to work very fine. I really don't know what to do.
I also tried some others video type and none of them are working... I even tried some video that I made from my old DV cam. There's nothing to do.
I will try to reinstall CS4 suite to see if something will change.
I have the same problem. Can't see video in main window, but when I choose Export>Media... It displays Video in output window. I've tried settings in BIOS - no effect.
System: Windows Vista Ultimate SP1 x64
Intel Qore2Quad Q6600
nVidia GeForce 8600GTS
No additional codecks were installed.
Good news!! It seems to be working, for now. After a few researchs, I found out that some Adobe softwares are dealing with video drivers differently in the CS4 version.
I downloaded the latest version of my graphical adapter (EN8500GT). I then updated my driver to the 126.96.36.19920 and it seems to work with all kind of video.
I'll make some tests and I'll give you some feedbacks!
