    First off I admittedly am a complete rookie when comes to all of this but not an idiot by any means -- still I am stumped...

    I've been shooting an Indie film and have shot a lot of crisp, detailed footage for transitions etc that looks excellent. However, we filmed a few scenes and when we were looking at the footage on the big screen it didnt look as crisp and had a lot of grain / pixelation going on.

    My thoughts were maybe that the lighting we were using was inefficient but we shot some great low lighting test footage when we got the cam, that still looked very crisp.

    Our scenes however just dont look like they were shot in HD when we go to put it up on the TV. We are running through the camera with HDMI to 1080P DLP 46 Inch TV and like I said some of our footage looks amazing but some of the other stuff looks awful and unusable.

    The information I've given may be too vague for a diagnosis but perhaps someone can give me some scenarios, tips or pointers. I would greatly appreciate it.

    Thank you.

    It sounds weird. I´ve used the camera a few years ago when it came out for a TV show and altough we had technical problems with it it produced good footage.
    I presume you shot in 720P?
    If so there is upscaling going on somewhere and that could increase the damage to the footage.
    It would be good to know what kind of scenes looks good and what looks bad.

    Could it be that you have used a lot of gain in low light situations, with or without purpose?
    That could look good on a small screen, but turn up pretty bad when shown on a big screen.
    Maybe if you can post some footage for us to look at?
    That would make helping you easier
