Hi,
Im shooting a music video tonight, and have borrowed an XL2 for the job. Ive done some tests putting it on a jib arm and shooting at 25p (im PAL) and 1/50 shutter. When I play the video back on my TV straight from the camera, I notice two bad things:
1. The 25p image is very jittery
2. In shots where there is bright strips of light (ex, sky through a picket fence, or a reflection on a metal drum stand (see pic), there occurs sort of small moving bars of a rainbow of colours, just near spot where the bright strip is.
The thing is, when I capture to PC, neither of these problems occur. Motion is great (I guess cus PCs are progressive scan), but the coloured artifacts are missing as well...there is a very faint sort of ghosting (see pic), but no colours. Please help me out, is there anything wrong with the camera? If not, what do I need to do to make it look better on TV?
Thx so much for any help, Im really running out of time!

EDIT: I just tested further, this may provide another clue: If I plug the camera in manual mode straight into the TV (thus not using tape) the image still contains these artifacts (mostly small moving transparent blue bars on bright areas during camera movement). It occurs in BOTH 25p and interlaced modes.
