I just purchased this new laptop today with 1.5Ghz independent video card and much faster processor than previous laptop I was having various troubles on.
On both laptops my HD video has horizontal lines, or distortions, running across the full length of the video. I have played the vidoe directly from the camcorder to the TV and it is fine. I also just used Media Player to play the video and it plays fine.
I have the most recent update to PD9. The only thing that is the same is that the software on both computers came off of the same disk.
I haad talked extensively with tech support when I was using the older computer and they had no idea what was happening. Now I have a brand new laptop and the same issue. (I haven't even tried to render vidoe on this new one yet to see if it is much faster than the 14 hours my old one took to render vidoe.)
Any ideas?
Thanks,

Can you post a screen shot of the distortion?
What is the file format of the video and what profile are you producing it to? __________________________________

Thanks for the response Jaime. I am now mystified! After rendering the video on this new computer the lines are no longer visible, but on the old computer they didn't go away??
I am attaching a few seconds of video so you can see what is happening. In this particular peice the video camera wasn't quite synced to the projector and I got the dark roll line, but that is not what I am refering too.
I am happy that this new laptop did render my video in 7.5 hours compared to the 12 - 14 hours it took before!
Hope this sample tells you something. I am going to ask tech support if I can download the software since I still feel that is where the problem is??

Thanks,

Jamie, I was wrong. The lines are still in the rendered video, but maybe not as noticable. I attached another clip for you, or others, to look at. This very same clip looks great when played from the camcorder to the TV, and also in windows movie maker.

I have another 10 minutes until tech support opens up.

Thanks again,

Thanks for the response rocket man. I don't know if that is it or not. How do I check to see what my camcorder is set too, and what PD9 is set too?
It is a very good idea to check, I just am not sure right off how to do it. I will explore some on my own, or until you, or someone else, gets back to me.

Interlacing is also what I was looking for. Try producing to 720p and see if the situation improves any. It may still look a little fuzzy around the edges, but the lines should be mostly gone. I don't know how to check the setting on the camera. Depends on what type of camera, I guess. On my Canon the is a menu where I can switch it from 60i to 30p. __________________________________
