1920 X 1080?

” The Panasonic Varicam and HVX900 cameras are 720 “native” imagers, as distinguished from the Sony 1080 imager;”

To clarify, the Sony f900 750 f950 imagers are progressive.
However the frame is split into psf for on board recording.

Take a frame grab from f900 or Varicam or film and in respect to motion capture, they are pretty much identical.

XDCAM HD and X300 cameras use what I call (!) an interlace imager with on chip processing to create progressive frame.

I don’t think it matters. I have attended IBC and seen Varicam on a large screen and no one could tell if they watching 1080 or 720? It just looked stunning.

Hi – I know this is an old thread but it raises a question I have.

I ahev been using the X400. Whilst this has 720 sensors it upconverts in teh camera to 1080p as you know. Does the varicam do the same thing? We are currently converting 720p varicam footage after the event. I though the cmaeras had similar insides. Can you tell the varicam to up convert in camera to 1080p?

Many thanks.

You have to understand that there are differences both in the native imager and in the recording format that return us to the old 720p vs. 1080 PsF arguements. The Panasonic Varicam and HVX900 cameras are 720 “native” imagers, as distinguished from the Sony 1080 imager; the recording format is also 720 vs. 1080, so that the Panasonic is forced to “crossconvert” or as some might say “upconvert” the 720 signal to 1080 when directed to do so. That is not to say that it is any worse or better!

Many folks make the point that an particulat 720 field has more resolution than a 540 “field” in the HDCAM, and the ultimate quality assessment is very subjective, especially as regards use in television where transmission and HD display characteristics inly “dumb-down” the picture.

The only time this discussion really has any merit is when the intended use is for “film-out”, namely conversion to motion picture film for exhibition in a conventional cinema; here a native 1080 imager and recorder will show a slight benefit.”
