It really depends on the lights. Proper high speed flicker free florries will be OK, but normal office lights will quite likely flicker.

FCP 7 is very poor at handling any kind of Mpeg 4 file. I would use a different edit software for mpeg 4. FCP-X or Premiere is much better for mpeg 4.

You probably want a switcher with HDSDI but without knowing more about exactly what features and functions you need it's impossible for anyone to suggest a specific model.

This is probably due to the use of a blue LED as the backlight source. Blue LED's emit light well into the ultra violet spectrum and this intense UV light causes problems for most cameras. As yet I don't know of any fix for this. It also occurs with blue and purple LED lights used for stage lighting.

What are you editing with. I've not seen reds blow out like that. It may be your edit software clipping the luma as it looks a little over exposed. Also your knee settings may need looking at.

In case you didn't see it Sony showed a pre-production PMW-400 at NAB. The PMW-400 (available August??) is basically a PMW-350 (2/3" CMOS) XDCAM camcorder with the addition of an extra HDSDI output and flash band compensation. More importantly there is the addition of the XDCAM HD422 50Mb/s cod...

Yes this is normal. There is a maximum number of files that can be stored on a single card or optical disc with XDCAM.

For your pleasure and delight I have uploaded a couple of short 4K raw files for you to play with. Deliberately push the exposure to the limits. You can use the free version of Resolve Lite to play with the clips.

You'll find my review of the JVC HM-650 here:

The F3 has a backfocus adjustment screw. Maybe the F3's backfocus is out?
