So my problem is video does not playback in the Composer Window, either side. You hit play and the video stays frozen on the first frame while the audio plays. Hit play again and the video updates to the current frame.

You can drag your mouse around and it updates frames quite fast, but will not play back at normal speed or any speed

I'm kind of our of ideas of what to try next.  So yeah, I got no clue and any help would be wonderful. Specs below.

Thanks so much,
Remondo

 Kinda hard to help without system specs, but I would suspect it is a video card issue, meaning that you are not running a video card that is on the recommended list, or you if you do have a recommended video card, then you are using a non-certified driver.

I had this same issue when I first got MC...I was trying to run it using an ATI card and MC didn't like it....the workaround at first was to use the Legacy video overlay feature in the console (I don't remember the commands, but a search in the readme mentions it I believe), I then purchased a QuadroFX 3450 and everything ran smoothly.

I found this on the legacy video overly...here is a copy and paste from the original post from BAKLAP:

Legacy Graphics Cards (Windows Only)

With some older generation (or legacy) graphics cards, you might find that desktop video
runs very slowly or that a “Serious Error has Occurred” error might appear on startup. Some
systems with legacy cards might run better if you use the old legacy (DirectDraw overlay)
code instead of the current OpenGL shaders. If you receive the “Serious Error has Occurred”
error upon start, hold down the “L” and “O” keys when launching until the first dialog box
appears. This turns the Legacy Overlay feature on until you restart the system again.

To turn the Legacy Overlay feature on:

1. Select Tools > Console.
2. In the Console command line, type:
legacyoverlay on
3. Press Enter.

You can turn off the feature by typing “LegacyOverlay off” and restarting the
application.
On some legacy display cards, especially when they are set to higher resolutions, you might
need to disable the OpenGL effects to get the overlays to function. This can be done by
holding down the "O" and "G" keys, or using the disable3d console command.
Qualified Graphics Card Setup (Windows)


The following features are affected when you set the Legacy Overlay feature on:

• No Full Screen Playback.
• Full resolution HD does not work due to Direct DrawOverlays size limitations.
• On some cards, driver versions, and resolutions, overlays don't work, so you won’t see
video playing.

Video card: mobile intel 965 express chipset family with latest drivers

Is this the problem?

I've tried Legacyoverlay but it still doesn't work[:'(]

Remondo,

 I very highly doubt that Media Composer will run with that card. On the PC it is designed to run with QuadroFX cards.

I ran into this yesterday. It was with content edited into a duplicated template. I don't know if this is your situation, but this is how I fixed it.

There was a problem with with the duplicated template, I guess, somehow, it got corrupted. I used the content from that template and edited it into a new duplicated template. That fixed it.

You can also create a new sequence (if you are not using a template)  and try editing your already cut content into it.

If you are on an Adrenaline, you may want to power cycle the box as well.

Technology, eh...

Good luck

thanx headscutter,

but i tried too create a new sequence but still the same problem

maybe you have some other suggestions?

thnx Remondo

Hi,

Like Mark said above, you're probably not going to get that card to work.  Here's a link that might help, but you're probably better off on another system with a Quadro FX card.

good luck,
Carl

but i'm working on a notebook

is that a problem?

Hi,

The problem isn't that you're on a notebook, it's that you're on a notebook that has a graphics card that doesn't work with Xpress Pro.  As you're finding out, there are very specific system requirements for Xpress Pro.

Sorry I don't have better news for you.

good luck,
Carl

the problem was quicktime when i installed quicktime 6 the problem was solved

thnx

Remondo,

That's why it's important to tell us your system specs, including QT, when you post.  Had we known that, we might have been able to help you sooner.
