The NoiseReduction in camera test (NR0, NR2, NR4). The best part is ISO4000 25p (18:58), log gamma at low iso 850 has poor result in lowlight + big gain at postproduction.
Samyang 24mm/f1.5, a very poor light, ISO850, ISO1600 25p (10:20), ISO1600 25i + deinterlace (15:56), ISO4000 25p (18:58), internal AVCHD+external Ninja2 recording.
Avid Symphony at postproduction, I was working with these versions of clips (in this order):
1. AVCHD in XDCAM long GOP HQ 35Mbps 420 codec
2. AVCHD in Avid DNxHD185 (422, 8bit. I-Frame only) codec
3. Ninja2 version in Avid DNxHD185 (true 422, 8bit, I-Frame only) codec
4. repeat "1." for better visual contrast with "3."
All these codecs are present with NR0, NR2 and NR4 versions, with three levels of ISOs. There were NO COLOR CORRECTIONs at post, I did only a minor black setup (with master pedestal) for the same start point in black and I increased (a lot) the gain level for canon-log clips with low ISO, nothing else (in higher ISO there was no need for such increasing level of gain in post, the canon-log result is much better in this case).
The result was exported in DNxHD185 (422, 8bit) and for vimeo this master file was transcoded in Sorenson Squeeze to H264, with 15Mbps in slow (high quality) rendering. I sugest to download the orig H264 file (DNxHD 185Mbps version is the best, but it is too big file for vimeo).
C100 has a higher noise level in black parts of pictures, the higher ISO level helps with this so the best result has cine1 gamma, NR2 and ISO4000 level version of clips (in this case of scene with a poor light). Also different gamma have a different noise levels (and 25p version is much sharper and better than 25i version). In the picture is also a small PIP with the 400pct magnification which helps to see the differences (also in chroma subsampling 420 vs. 422 on the test chart). ABB was made for all different ISO parts.
Look at these three pictures from NINJA2 at a full quality (NR0, NR2, NR4):
Thanks to Pavel LOPOLO Jirak for lending the Ninja2 recorder.
