No freezing with Workhorse-Flowmotion setd, Lexar card 600x (90Mb), Autofocus single, OIS stabilizer.

@TrackZillas @frullaccia @JayUKB

I advanced some tasks today, and in the late afternoon I did measurements, tests and tweaking in the frame buffer and frame limit keeping same datarate for all slots.

I think I found the GH2 G Spot! the camera went into multiple orgasms...

120Mbps datarate in all slots, tests with the 45Mbps card in NTSC and PAL:

30 seconds recording in SH, H, HBR, 24H and 24L without camera freeze, without stop recording. Using the 14-42mm Kit lens, auto focus disabled, OIS disabled, on the SDC4 death chart.

Will need your tests in 80Mbps 95Mbps and 280Mbps cards to be sure about stability (I just have the 45Mbps card).

If this thing can record some minutes in fast cards it will be the Fresh Orange Juice from the GH2!

I will upload this patch when my tests get finished.

@joethepro we are tweaking it for more stability, so the image tests will come later. there are two videos on vimeo showing the lowlight results in previous posts from patch before these new tweaking.

@apefos WOW!!! Nice man.. Will test in the morning before my video shoot. If all pans-out I will be shooting some nice slomo tomorrow. Once again thank you for all your hard work really appreciate it cheers.

I forgot to tell you that I also tested the 80% frame rate. Everything is ok. I will do some new try in the morning.

@frullaccia Many thanks for the reports. It seems I found the final tweaking, I hope. Now I will do the same things in the other datarates. Did you got stability in some minutes recording?

@TrackZillas waiting your results!

Guys, about PAL in NTSC lands, I live in 60Hz country, when I point the camera in PAL to the computer monitor, after press record, the image shows dark and bright strips which scroll up. Shutter 60 does not solve, the frame rate is mandatory... Under the sun there will be no problem because sun is fire, but under artificial light I think it will be no good. I will do my best in 720p60 also as I did in 720p50 in this last patch.

This last patch is 120Mbps, highest possible in all slots. This thing working proves that the others will work also. The challenge now will be to make the 720p60 stable also in higher datarates, the camera will answer what it can do.

@frullaccia Maybe the more noise is due to the datarate is very high and then the codec preserves more the noise instead of flatten it, because higher compression tends to crush the noise.

you need to shoot exactly the same scene, same camera adjusts and same framing, same light to perceive subtle differences.

do you prefer more noise or less?

It's a good crime scene!

I've got a feeling that boson and workhorse will merge into one... not sure yet... things are pointing that there is a sweet spot between them... if this turns into feasible, noise and detail will be balanced together.

If this can be possible to do, I will call it the "G-SPOT" , the "G-H2O-rgasm" !

But as I said, it is just a feeling now... I will pursue it.

Maybe I'm wrong, I don't know how to explain, but there is a little difference between them.

the g-spot (boson+workhorse togheter), details and noise in same slot, seems to be possible for 720p50 in PAL because there is enough datarate to increase both I and P frames without get into the unstable datarate territory.

in NTSC, there is no way. no matter the gop table settings, the datarate does no increase enough to do it. in the highest possible datarate before camera freeze the amount of data to share between I and P frames are in the lower limit for both things together and chances of stability are small. one attempt to do it in ntsc is to put the boson better noise in SH slot and workhorse better detail in H slot, similar thing which boson versions already have.

Many thanks @Driftwood I saw the video, it does significant difference!

I will do a careful look in the SpizzT6 ini file! seems to be different approach than the T7.

much appreciated!

@apefos
Each of my settings are trials - i.e. they are all tested to work well. No single setting can be considered better than the other as each is using different variables and arguments. In the end it boils down to what kind of bitrate you want to use but of course the more applied, the more resources can be assigned to things like QP parameters and knocking out as many artefacts as you can with supreme settings. This is why Cluster X series has always strived for the best quality according to each GOP.

Just remember to test buffers with Elecard. You don't want them to overflow or underflow / or decline rapidly which will suggest problems.

Driftwood 'Space' and a few other settings in the past (like REDshift) strived for performance at lower bitrate settings for people making documentaries etc.

Somewhere Ive covered all the goalposts at some time or other with my settings whether its Intra or Long GOP! But everything can be tweaked and its good to see you tirelessly keeping the GH2 settings tuned to max! Keep up the good work.

@apefos Just tested your latest WorkHorse Nebula Patch all I can say is the quality is amazing those i-Frames are the highest I've seen. Using 80mbs card & manual lens 720p 50fps only got around 18 seconds, couldn't test out with my other 95mbs cards because they were formatted for the BMPCC. Images looks really awesome great work.
