Really bad aliasing and moire but is it from my HMC150?

I was asked to shoot a 4 games series for my daughter's soccer team in Santa Barbara this last weekend. I did so, and am now working on producing several videos of her team mates to help them in getting a sports scholarship. All seemed to go well and the footage, when played back in-cam, looks really good. However....once I load it into Premiere Pro 5.5 to edit, I see such bad aliasing and moire that it really renders the footage useless. It is seen in the goal netting, and vertical fence posts. But only on the Premiere Pro timeline, NOT in the footage when played back in the camera or when clips are played back in Windows Media Player. Then it looks just beautiful. It was shot at the fields at UC Santa Barbara. I don't understand why the footage could look fine in-cam, yet be soooo bad on the timeline. Never seen that happen before, where there was such a huge discrepancy in what I thought I shot, and what I get on the timeline. All footage was shot at 1080/60i. Timeline is also same. What's going on??? Any ideas / comments on what do do next would sure be appreciated!

The reason you're seeing the aliasing is because you shot in 60i. Aliasing and moire is just a bi-product of shooting interlaced footage. If you shoot in something like 1080/30P or 720/60p it should fix your issue since it's progressive.
Also, watching interlaced footage in Premiere's tiny preview window may accentuate the presence of the aliasing. If you watched it in full screen in Windows media player the moire wouldn't be as noticeable. You also may not have noticed it in the camera's LCD because it is only 230,000 pixels and High Definition is somewhere around 2 Megapixels so the HMC's LCD resolution wouldn't be high enough for you to notice any artifacts.

Could you maybe post a link to some of the footage you shot?

Also, what scene file settings were you using when filming the footage?

Hope this helps! :beer:

Thanks Mountain Wolf, you were right. I first took the worst case clip and just burned an mpeg 2 file, since these customers just want SD anyways. I played that file back on my Panasonic plasma, and saw no sign of all that aliasing. It did scare me because I'd never seen this camera do that before.
