Vegas Pro 12 ; No video preview

I just upgraded to Vegas Pro 12 .

There is no video preview during playback or when stopped.The only way to get video to show in the preview window is when you resize the preview window but it disappears as soon as you let go of the mouse. If I click the "preview button on external monitor" button the preview works in the small window as well. But as soon as I disable external preview there is no preview at all. I'm using AVI 1920x1080 Techsmith codec.

Are you saying there is no preview only with a particular clip ?

I would look at the Trimmer display button; the Split Screen preview button and track muting seem OK.

I get no preview with any AVI clip and no preview with MP4 clips. I noticed that if I click the overlay button the image appears although it has grid lines on top which I can't get rid of.as soon as I turn off the overlay button the video image disappears.

They all seem to be OK. This is a fresh install of Vegas Pro 12 so importing a video should automatically display it in the preview window yes?

I would disable GPU acceleration and see what happens.

OK I figured it out. I uninstalled it and reinstalled and ticked the "run this program as administrator" box and now video preview is working. I guess I should have realised that. Sorry to waste your time and thanks for your suggestions.

I had this problem too, just got rid of it by downloading the latest beta drivers from Nvidia, using 470 GPU cards

I know I'm way late coming into this, but this might help someone. I had the same issue and I had a workaround and a solution. In my case: The workaround was, I could turn on the Safe Zones and the video would appear. The solution was that I have two video cards installed, and I could click on the preview window and select Video Preview Preferences. Then in that dialog next to GPU acceleration of video processing: there is a drop down. I had the wrong video card selected in that drop down. When I selected the correct one and restarted the application it started working.
