Newsmeldung von slashCAM:Test: Test: Panasonic AG-HPX301E - Extremely HOT & Handling of top-rob - 27 Aug 2009 17:29:00 > With the Panasonic AG-HPX301E leads a series of premieres in the line-up of his professional HD camcorder-a: For the first time (on the so-called HDMOS sensors, CMOS-related) set the 100 Mbps AVC Intra codec is the first time in the professional entry-level segment and is also used for the first time provides a model AG-pixel shift but not full raster HD. Since we already have the pre-series model may undergo a short test, left a positive impression of the (; exception of the somewhat weaker lowlight performace), we now had a couple of days a series of execution for a visit.

Antwort von Bernd E.:
... As an indication of the relation of image quality and data rate is one of approximately 50% efficiency of AVC Intra made of tone compared to DVC PRO HD. Will: DVC PRO HD at 100 Mb / s provides roughly the same picture quality as AVC Intra at 50 Mbit / s hot for the same image intensifier ... Small s.Rand Note: If AVC-I, twice as good as DVC PRO HD is compressed, then the efficiency is 200%. "50%" would mean that it is only half as efficient.

Hello Bernd,
Thanks for pointing - is currently being re-played.

HDMOS sensors (; CMOS-related) "HD" MOS CMOS is not only related, but synonymous CCD.
Even "tighter" than with CMOS, because it has no structure combined ..
The term CMOS refers to the manner in which the sensor is manufactured and is therefore not a special recording technique dar.
CCD, however, describes the underlying operating principle of the camera.
Herstellungsseitig CCD is certainly also an MOS.
Only then supplementing that there be no misunderstanding ...
The yellowing of the lens you get very effective way, with the white shading correction setting. This leads synonymous not mean that the white balance of the blue channel needs to be strengthened so disproportionate. (; or the R / G channels so strongly damped and reinforced the overall signal, which is actually the case). The noise values are then balanced and the darker images are no longer synonymous of the "Rotnatur", as shown in the test.
The many settings of the Camera should like to use. The images are still a good bit better.
Because the test only from 1 / 3 "is mentioned, should be additionally noted that it is in the sensor, at a 16:9 design, so do not compare with is the usual" normal "4:3 sensors.
The custom design and the newly developed chip leads not only to approx. 17% more pixel area available, but synonymous with a changed "Filed of View" and thus a change in equivalent focal length of the lens.
The relative distance to the traditional 1 / 2 ". A simple size comparison 1 / 2". /. 1 / 3 "is not of the case.

I find it extremely difficult to portray such an artificially überschärftes image signal as a positive criterion - such overshoots s.allen edges of the image, I only know of amateur cameras and from U-Matic unhappy times.
If one were to cut back Anschärfung, would be the picture might be compared with that of the EX1, but it is at LowLight dramatically worse.
I tried the camera recently - with only succeeded with difficulty, with which it sharp serienmäigen viewfinder.
Quite different with the 700s of JVC, it was me without any problems.
I have been working 25 years with professional 2 / 3 camcorders and trust me, therefore, to a verdict.
