Two grabs, first is BOOM without CC and second BOOM with CC and ADB effect.- Soon ill post the entire video. Boom works great with this technique thank you very much Nick.-
Hi Nick @driftwood! :-)
I take care so that it may not become your obstacle, but how should I do?
sorry for the pic had to delete video do to privacy issues,the pic is of my homemade dolly I used in the deleted video.
Cluster DREWnet (12/15 GOP) v9 Boom 12/01/2013
Featuring;-
Cluster v9 'Nebula' 6 GOP 'Boom 4444 Matrix' variation with tighter i frames - Coming soon!
Driftwood the GH2 'Low Rider' trial Setting and report back any findings. :-)
With Low Rider we are using Quantisation to drive the bitrate and quantisation together with Chris Brandin's excellent AQ routines on top of a fairly mid-range lowpass frequency CQMatrice.
The whole idea of Low Rider is to see how low we can get QP (and how to balance the CQM with Initial Q) for most sorts of pictures without introducing artefacts etc... Subsequently, the encoder resolves great picture detail at Low Rider's Intra modes (and 3 GOP on 720p) without neccesarily over taxing the encoder with an intensive matrix.
The Low Rider matrix is tighter than stock levels but nowhere near as 'pushy' as some of the other Intra matrices of the past. I initially chose a IQ of 16 but felt 17 offered a more balanced overall picture quantisation without greater degrees of DC range.
The result is macroblock QP ranges of 9 to 20 (often lower) for most pictures and perhaps the best overall Intra yet. However, you decide and test.
Low Rider test 2 and 3 have been shelved and the research now forms part of the newer Cluster X series.
Currently, Low Rider eats the following out of your precious (decent) SD card;-
Info for Testers:
Quantum GH3 Matrix Setting Test 2
Recommended: Good for Intra documentary making.
Low mem cost - Great quality 1080p24/25p/30p Intra utilising the .mov GH3 matrix scaling tables & deblocking simply inserted into the GH2. Plus 3 GOP PAL 50p and 6 GOP 60p 720 modes. cbrandin's AQ1 and AQ2 is back in use here providing avg 14-16 Q for 1080 modes and lower for 720p modes. Experimental Setting requires testing.
Cluster 'DREWnet' GOP12/15 (LongGOP) Test 4 version of the GH3 Matrices. Including:-
Note: The GH2 does not employ adaptive 8x8 & 4x4 Transform as does the GH3.
*** NEW ***
Cluster v8 'DREWnet' (12/15 Classic PAL/NTSC GOP) variation with cbrandin 'Cinema Smooth Matrix' Released 11/01/2013

Cluster v8 'Nebula' 6 GOP TBA
Apocalypse Now - Settings
Apocalypse Now 'Intravenus' v2 With cbrandin 'Smooth Cinema' Matrix
• Intra GOP1 24p & HBR/FSH +3/ 6 GOP 720p Modes - Released 29//12/2012
Another experimental setting in the Apocalypse Now suite. Not really a version 2 but a variation utilising Chris Brandin's other low pass frequency matrix. There are subtle differences between 444 matrix (see Intravenus v1 on other thread) and this one.
The main goal in tuning these settings was to achieve high PSNR (Peak signal to noise ratio) averaging around at least 50dbs on all modes whilst looking at ways of knocking out artefacts. We all know that PSNR shouldn't necessarily be used to judge picture quality, however, elecard's Q results continually prove that a high PSNR is fairly reflective of decent signal to noise whether or not human visual perception 'sees' not much difference. It certainly helps in the grade. A higher PSNR would normally indicate that the reconstruction is of higher quality.
Once again this setting pushes things to the limit and you will need a decent hi-speed SD card to make use of not only very high Intra 24p but also 80Mbps+ averaging for HBR/1080i and 720p modes.
Once again, a big thank you to @cbrandin in analysing and developing the 'Cinema Smooth' matrix.
