Thanks for the reply.
When I place video clips on the timeline, they play fine. However, if I add an effect (such as RGB curves) the preview is black/blank, with a red line over the clip in the timeline, and when I hit play or scrub the timeline the preview remains black, with only audio. Also, when i place an image (such as JPEG) on the timeline, same thing happens. Black. I have had these results using various clips: h264 in mp4, 3gp, avchd, uncompressed avi.
Rendering allows it to play (green line). Export video works fine.
After Effects seems to be working as normal. Could this be a problem with compatibility between the mercury playback engine and the intel hd 3000 graphics? I have updated to the latest and tested intel drivers from the Asus website. This is a brand new computer. I find it hard to believe that the integrated graphics won't handle this.
I have no third-party effects or codecs installed.
I am running no other software.
Here's more detailed system info:
Asus P8Z68-V LX.
- Intel Z68 chipset. Intel HD 3000 graphics. i7 2600k CPU. 8GB 1600Mhz RAM. HDMI output @ 1360x768px
- Using windows 7 ultimate SP1 64-bit. Adobe CS5.5 full suite. (inc. Premiere Pro CS5.5.2)
I find it hard to believe that the integrated graphics won't handle this.
I don't. Honestly, the first thing I'd do is get my hands on an nVidia graphics card with at least 1GB of onboard memory and install that.
I thought I wouldn't need a graphics card (I don't know why)
It figures the problem though - if i turn off the windows aero theme in i get a flickering video preview instead of black.
Very dissapointing but I'm happy that you could clarify what's happening.
Thanks for your help.
