Boson

apefos

WorkHorse Boson

highest possible careful tweaked settings for very high image quality with enough stability for short takes up to 5 - 8 minutes.

Improved for best low light noise and textures in all modes, perfect for high iso, and excelent image texture in good light.

Arri Alexa image quality inside the GH2, (just missing the Alexa dynamic range of course)

default version:

*SH and H slots are better for good light in low iso and for more detailed scenes in good light

*SH slot is higher quality and more stable with manual focus legacy lenses

*H slot more stable with native lenses with electronic contacts

*H slot also better for use with image stabilization

*hbr is better in good light than in low light

*default version is more stable in SH and H 720p and in HBR than the boson version

*24p 24H and 24L are the same of boson

*great quality in all modes

boson version:

*SH slot improved for low light textures and noise

*H slot better for good light in low iso, better for more complex details scenes in good light

*H slot is more stable for native lenses

*HBR does the low light / good light balance automaticaly for better noise in low light or better detail in good light

*24p has same noise quality in both good light or low light for constant image texture this keeps same random noise in all light conditions, good for intercut with SH

*a little less stable in 720p and HBR than the default version

*best quality in all modes

seta = workhorse default

setb = workhorse boson

setc = workhorse default lower datarate in SH and H for more stability in 720p and hbr

setd = workhorse boson lower datarate in SH and H for more stability in 720p and hbr

sete = same as seta, but the 24H and 24L are optimized to deliver sharpest image for steady complex detail scenes, it does the automatic adaptation in 24p for low light noise or good light steady complex detail scenes

setf = same as setc, but the 24H and 24L are optimized to deliver sharpest image for steady complex detail scenes, it does the automatic adaptation in 24p for low light noise or good light steady complex detail scenes

all tests performed in NTSC with the Sandisk 32GB SDHC Class 10 U1 45Mbps card.

transcode the original mts files to Apple ProRes 422 full range using the 5DtoRGB free software before editing to avoid the diagonal pattern rain problem. Try the ProRes HQ, normal and LT versions to perceive the best balance between quality/file size.

as of september 05 2014 all versions are modified flowmotion 2.02 with extensive careful tweaking

I uploaded new versions in the workhorse topic, it will be better to keep all discussion in one topic:

http://personal-view.com/talks/discussion/11079/workhorse/p7

apefos

for PAL and NTSC shooters who want to use boson and workhorse: compare previous boson and workhorse versions to perceive stability (versions 09 september and before), there are different gop tables in the versions and some are more stable than others.

apefos

these versions are completely unstable, I abandoned them:

apefos

remember that the 720p pal is higher datarate than 720p ntsc, so maybe in ntsc it can work.

these BN super fast versions below is same datarate in all slots, setj is 100, seth is 104, seti is 112. if they does not work, so the way will be to avoid the super fast versions and keep using the 09 september versions, because the 09/09 versions already have 96Mbps and are reliable, so less than 100 will not improve significantly.

apefos

Try BN setf, it is a little lower datarate in 720p than setg. if it stop, the way will be to avoid the superfast versions and use the 09 september versions only. because the difference from the 09/sept. seta to this superfast setf is small, so tweak it does not make much sense.

JayUKB

BN setg...on 720p stopped within seconds, with a card error message....needed a battery pull/

apefos

@JayUKB

thanks for the 720p SH test. it shows that the 720p SH in seta can be reliable with a fast card. streamparser is showing good results.

I edited the post above about what is BF, BN, WF, WN, please take a look. Would be great you do a try on these high datarate versions on your card, as it is one of the fastest card available today. If it works on your card it will be amazing because they improve image due to more datarate.

Many thanks for your useful reports!

JayUKB

What's BF and BN?

720p (PAL/50) SH test...using the seta in "workhorse_boson_07_september_2014_ntsc_pal.zip", from a few days ago. Using the death/colour chart again, same Sandisk 64GB 280 card. The camera stopped after recording a 4GB file, so no spanning.

apefos

this is experimental, to be safe use the 09 september versions.

Boson - WorkHorse for Super Fast Cards:

This is an attempt to improve the image quality even more increasing the datarate

This can help the 720p SH in Boson to be better for complex details

This can help the 720p SH in WorkHorse to be better for textures and fine random noise

Try these patches in 80Mbps cards and above

Try to record a 4GB file in each mode, feedbacks welcome!

About the datarate increase:

BF and BN setf = one step above seta

BF and BN setg = two steps above seta

WF and WN setd = two steps above setf

WF and WN sete = one step above setf

BF = Boson Flowmotion

BN = Boson Nebula

WF = Workhorse Flowmotion

WN = Workhorse Nebula

This is a complement for the september 09 versions, there is no new settings, just datarate increase, experimental

Boson and WorkHorse Patches for GH2 Hack

Works in NTSC or PAL
Developed with PTool 3.65d
Careful settings for very high image quality with enough stability
For short takes up to 5 - 8 minutes
Excellent textures and fine random noise
Excellent results for images with complex details

Boson:

SH 720p slot: improved for best textures and fine random noise in low light or high iso
H 720p slot: same datarate quality of SH, but improved for complex details and low iso
HBR: can do both things, good textures and fine random noise or complex details
24p: constant good noise and good complex details, sweet spot for cinema

WorkHorse:

A little more stable in 720p than Boson
Both SH and H slots have slightly less noise quality than boson, but are great for details
The SH slot has higher datarate than H slot, H slot is an option for better stability
HBR has same Boson settings but can be more stable also due to share some 720p settings
Same image quality of Boson in 24p

From seta to sete of Boson (5 versions):

The difference is: seta has the highest datarate for 720p and hbr, the 720p and HBR datarate decreases a little in each version, this is for you to find the best stable version for your camera+card+lens combo. Try the seta first and change if needed.

From setf to setj in WorkHorse (5 versions):

The difference is: setf has the highest datarate for 720p and HBR, the 720p and hbr datarate decreases a little in each version, this is for you to find the best stable version for your camera+card+lens combo. Try the setf first and change if needed.

Memory Cards: Developed with the Sandisk 32GB SDHC Class 10 U1 45Mbps card. Very fast cards recomended. Use TOP memory card, it can improve stability for more continuous time recording, and for use image stabilization and i-Dynamic.

Tips: Manual focus legacy lenses allows more stability. Disable image stabilization and i-dynamic when using native electronic lenses for more stability or load a lower datarate version or use a fast memory card.

Matrix Tables: These versions of september 09 2014 have the Boson and WorkHorse with Flowmotion or Nebula Scalling Tables and Deblocking Tables. Fallback Tables tweaked to deliver more constant size in the frames along the frames's flux.

I am tweaking the fallback tables in the nebula versions to make it better. this will make the frames more constant size along the frames's flux.

I did careful tests with Nebula T8 matrix in the death charts and in low light.

Two positive feedback, one negative feedback (the negative feedback makes it a "no go"):

a little more sharp in the death charts.

in low light the noise is nore fine in dark areas, beautiful, makes the very dark areas more filmic.

there are some stuck pixels (bright pixels) sometimes pulsing in the image, more noticeable in dark areas, so this makes the Nebula matrices unfeasible. I noticed this in 24p. There is also a report about this in the topic discussing the Nebula.

It seems the flowmotion matrices are in the sweet spot, extract more from the sensor makes the stuck pixels shows up.

apefos

Nebula-Boson (the Scalling Tables and Deblocking Tables from Nebula T8 are merged with the Boson)

I did no tests yet so I do not know if it will be stable...

apefos

Interesting information in the stramparser is the average size of I frames and B/P frames. when the I frames are high the codec is doing a good job for details, when the B/P frames are high the codec is doing a good job for noise and textures. when both I and P/B frames keeps more constant the image texture will be constant for noise/details, 24p works this way. If the settings I did works OK, the HBR will change the I B frames size for details or noise when needed, this first reports shows it is working for details in the death chart because I frames are high. So it will be interesting to see how it will perform in low light also, how will be the size of I and P/B frames.

apefos

After some rest, I did some tests with the SH and H 720p in sun light foliage. The H mode works great for very detailed scenes in low iso while the SH is better for situations in low light and high iso.

The SH shares more data to the P frames so the noise is better, the H shares more data to the I frames so for complex details it is better. Good thing is that the Boson can do both things without change the firmware, just using SH and H for different situations.

I tested the sete also which has the lower datarate for 720p and the quality is very good for noise in SH also, good surprise. it keeps around 48Mbps while the seta keeps around 70Mbps

I did not get stop recording yet in the seta 70Mbps but I just did short takes until now.

I am curious to see if a fast card will hold long time recording with the seta in SH and H to get the highest quality in 720p without stop recording, but I just have the 45Mbps card...

apefos

@JayUKB keep up the great tests! It is important information about the performance in fast card. Your reports are very useful. thanks.

The spanning and no stop recording are showing that the camera hardware can handle the heavy data even in HBR. this is amazing. the streamparser information shows is very useful to perceive the performance. this results on a death charts are proving a reliable performance for real world shoots.

I am curious to see about the 720p because it is the most difficult mode for the camera and card to handle. I just own the 45Mbps card so these tests with a fast card are very important information.

apefos

@JayUKB great to see you got spanning, this shows how important is a fast card!

the playback in camera is not expected to work for all recorded files, until now I got no problem in computer, all files I recorded can playback in the PC.

I will get some rest now, after intensive work.

Many thanks!

apefos

@frullaccia thanks! hope it will be useful for you

@JayUKB thanks for the tests and measurements! the 24p 24H and 24L are expected to record more stable. The most interesting tests will be in the 720p SH and in the HBR because these modes are the best improvements in the Boson and are the modes more fragile to stability. this is the reason I created 5 versions lowering the datarate a little bit so people can find the best datarate for the memory card in these modes. As you own a super fast card it will be useful information to test the seta "A+ version" in SH and HBR with your card. Many thanks!

some tips: manuall focus lenses allows more stability. native lenses with electronic contacts can stop recording when using the i-Dynamic or the image stabilization in the SH and in HBR.

JayUKB

OK, now tried 24p 24L setting - all other testing as above (e.g. seta, death/colour chart, SD card, etc) Card reformatted (in cam) before test. I stopped recording at 14 mins before the camera stopped. Two spanned files produced, second one being about 3.8Gb.

Tried camera playback, didn't work Tried the camera off-camera on trick, still no luck Tried 'record a small clip' trick, got "Cannot Record, File Number limit exceeded"!! After formatting the card, I took the camera outside and tried recording a few short clips (about 30s-1min each) to see if I'd get the same 'file number' error; it didn't reappear and in cam playback worked (without any tricks!).

JayUKB

I'm doing some testing of Boson (seta), which I guess you'd call your A+ version, just using the Stray color chart with the stock 14-42 lens. All tested using 'Standard' -2,-2,0,-2; idynamic, etc. all off. The SD card used is the SanDisk 64Gb Extreme Pro 280MB/s. I'm in PAL land, and as I note that your most recent settings state both PAL and NTSC hopefully it'll work.

Started with (again, seta) 24p and 24H setting. Formatted the card, in camera, after loading the hack/patch. Shot just over 12 mins before I manually stopped, creating two spanned 4Gb files and another one of about 800mb; longer than your "short takes up to 5 - 8 minutes", but being a death chart test maybe not 'real life' usage.

StreamParser info of the 2nd MTS file - the middle one of the spanned file.

Tried camera playback, didn't work. So, tried the camera off-camera on trick, still no luck. However, I forgot to try the 'record a small clip' trick, before reformatting and testing 24L!

Is the above of any use/help??

workhorse boson, versions, 07 september 2014, works in NTSC or PAL

highest possible careful settings for very high image quality with enough stability for short takes up to 5 - 8 minutes.

improved to deliver the best textures and fine random noise in all modes

boson:

*SH slot improved for best textures and fine random noise (this is what makes the boson very special)

*H slot has slightly less quality than SH but it is more stable

*HBR is improved for great textures and fine random noise (very special)

*24p is improved for best textures and fine random noise (just best cinema)

workhorse:

*slightly less quality in 720p SH slot, almost unoticeable, but it is more stable than the boson in 720p

*HBR has same boson settings but can be more stable also due to share some 720p settings

*same image quality of boson in 24p

from seta to sete = boson (5 versions)

the difference is: seta has the highest datarate for 720p and hbr, the 720p and hbr datarate decreases a little in each version, this is for you to find the best stable version for your camera+card+lens combo. try the seta first and change if needed.

from setf to setj = workhorse (5 versions)

the difference is: setf has the highest datarate for 720p and hbr, the 720p and hbr datarate decreases a little in each version, this is for you to find the best stable version for your camera+card+lens combo. try the setf first and change if needed.

tips: manual focus legacy lenses allows more stability. disable image stabilization and i-dynamic when using native electronic lenses for more stability or load a lower datarate version.

Tested with the Sandisk 32GB SDHC Class 10 U1 45Mbps card. Very fast cards recomended. Use TOP memory cards.

as of september 07 2014 all versions are modified flowmotion 2.02 with extensive careful tweaking
