Rendered AVCHD from Vaio to projector: HELP!

I have tried numerous ways to foind a solution to my AVCHD issue...I CAN"T believe I'm the only one who wants or has tried to do this!!

Simply, I have taken AVCHD files I shot on a SONY HDR-SR1 1080i camcorder. I've made simple edits in Vegas Pro 8.1, rendered to AVCHD....all successfully. The whole purpose of all of this is to be able to edit and stream
my Family HDV material via the Vaio AW190, HDMI out to my 3 chip/1080p Runco VX-22d projector. When I do this I get what appears to be horizontal noise of some kind ONLY when there is motion in the video field. When it plays back and there is no motion or very little it is fine.

I have no clue what it is. Any one have any experience with this?

Thanks

sounds like you're describing interlacing artifacts. Your projector may not have a good deinterlacing system, if any at all.
Run a test on a short segment, rendered to progressive, see if you still experience the lines in the motion.

Two questions, what are you switching HDMI with and how long is the HDMI to the projector

On a side note do you have a PS3.

Hi Hunter.

My HDMI goes into a Lexicon MC-12HD. The HDMI out to the projector is only about 15'. I wouldn't expect that either would be an issue. I'm wondering if it has something to do with the video card in the notebook....or the HDMI in the notebook. It's very puzzeling and even more frustrating because I don't know how to figure it out!

I do not have a PS3 but i do have a couple of Bluray players. I watch alot of Bluray movies Thru the Lexicon via my Runco projector.

Anyone have any suggests? There's gotta be someone who's had these issues to deal with....

Your PC is not deinterlacing the material on-the-fly like a Blu-ray player would. You need to render progressive as Spot suggested. I would also not render to AVCHD as it's very difficult for PC's to play this back smoothly (at least my QuadCore can't).

Render progressive to mp4 or wmv HD and you should be fine.

Thank you for your reply. I will try this tonite. Will I loose any quality by rendering to mp4 or wmv HD? Are there any down sides to doing this? I know these are simple questions but very helpfull to me. Really appreciate it!
