M6 Sports Settings [gop 2]

mozes

GOP 3
Ad first, it was never meant to be released.
Many REAL good settings are already done, Driftwood, LPowell, cbrandin, Ralph_B, balazer, bkmcwd.
why then nevertheless released, well i think it have some settings that works different.
But it needs testing, i just have 1 gh2, 1 lens and just one batterie!!!!!!!!!!!
And it takes so much time, its a full-time job really............

M6 Sports (vbr) v1.0d.

Needs PTool v3.65d (280312)
Patch is based on::
Driftwood 'Aquamotion' AQ2 for Slow Motion Work in EX TELE mode -

Audio: thepalalias team pasadena-pulse-audio-v2-beta-2.

Scaling Tables: Driftwood Settings
Sedna AQ1. (Max Detail) ..

Mjpeg settings also from Driftwood.
HD = 1920x1080 and WVGA = 1280x720. (30p).
Tested with:
Olympus M.ZUIKO Digital ED 14-150mm f/4-5.6
And a Sandisk Extreme Video HD 30mb/s. card.
Bitrates: VBR: is between 35 and 100 mb/s. (all modes).
Average is between 50 and 70 mb/s.
MB/s depents on details in the shot.and also for spanning

When testing spanning, these where my average results... (tested on 1080 H and 720 SH setting).
720p pal is spanning. 3.99 gb 10:33min. and then starts next recording.
720p tele pal spans. 3.99 gb 09:13min. and then starts next recording'..(sometimes it doesn't span).
720p ntsc is spanning. 3.99 gb 10:33min. and then starts next recording.
720p tele ntsc is spanning. 3.99 gb 09:11min. and then starts next recording.
HBR pal is spanning. 3.99 gb 10:33min. and then starts next recording.
HBR tele pal doesn't span. 3.99gb and 09:27 min..(sometimes it does span).
HBR ntsc is spanning. 3.99 gb 10:33min. and then starts next recording.(sometimes it doesn't span).
HBR tele ntsc doesn't span. 3.99gb and 09:13 min
24p is spanning. 3.99 gb 12:43min. and then starts next recording
24p tele doesn't span. 3.99gb and 09:11 min. ..(sometimes it does span).
300% is spanning. 3.99 gb 11:28min. and then starts next recording
If it doesn't span, then the record will be saved, no lost footage..
Files can be played back on camera.

ps, last picture (dog) is HBR!!!!

Update M6 Sports (vbr) v1.0e give some tighter image...

@mozes That looks pretty good Mozes. It's also geared to 720-60 which is perfect. I'll try it out tomorrow. I'm interested to see how it handles lower light.

GOP 2
Did some test today with GOP 2 for 720 pal.
Its hard to say if its better then GOP 3..
Only when watching frame by frame there is some improvement.
The daylight was not that good today.

Shots are done in GOP 2 and quantizer was set to 1, YES to one!!!
Why GOP 2?? well, after reading this.

A GOP starts and ends with an I-frame, a conventional JPEG-compressed frame. These are the ‘known quantities’, compressed only from the data of that frame. In between lie two different types of predicted frames, the frames that carry only difference data. These are called P-frames and B-frames. P-frames are predicted from the I-frame at the beginning of the GOP, and B-frames are bidirectional frames created by comparing the data from both the start and end I-frames

I was thinking if B-frames only use info from the first and last I-frame, why not only use i and p frames.
I did want p frames so that 720 was not that hicky what it is if i use only i-frames

Video is done in vibrant -2 -2 0 0
In sony vegas the sgrb to crgb levels plugin added, and even more saturation (overkill i now).
But on my TV it look great.
By the way, ad the end there are some shots witch where done with gop 3 and 6.

Update.
Please use the new settings from next post

Forget the above setting, (i cant delete it!!!!!!!!!!!
Just updated seta m6_sports v1.0f with the deblocking tables from driftwood.

mozes

M6 Sports v.1.0h all gop2

Scaling tables and deblocking are frome @Driftwood Canis Majoris Day pm
Scaling tables for B-Frames are off.

@mozes, this looks good I will have to try it. Slow mo was done wtih twixtor right?

mozes

yes twixtor..... and sometimes i use motion perfect

720p, HBR and 24p on the same timeline.
Finally rendered to 1080 25p
No color correction is done!

M6 sports Version 1.1 have a better p-frame quality.
And follows the i-frame more, the bitrate is some lower, but the quality stays.

soundgh2

Looks like a nice patch :)

Rambo

Mozes, what are the p frames like with motion in v 1.1 compared with Iframes? It looks an interesting patch, I'd like to compare this to Sanity 720p 50.

mozes

Depending on what you are shooting.
But the goal is that it is still smooth, sadly enough 720 with only i-frames on a class 10 card what most off us have, is not reliable .
The record time is between 10 seconds and 4 tot 6 minuts.
I have included a pdf file how to set it to gop 1!! but only for pal, ntsc doesn't record more the 2 seconds ;(

So i thought, why not gop 2 with 1 i and 1 p-frame,
the settings before have a constant i frame with a variable p-frame.
and one with constant p-frame and a variable i-frame
Those settings give a higher bitrate, but a lower quality p frame.
Visual you practically see no differences, but if you watch frame by frame, you will see it.
Now with v1.1 where the p frame follows the quality from the i-frame, the bitrate drops, but the overall quality off the image is better.
That will give better results if you do in post some slow motion with for example twixtor..
In version 1.1 the i-frame keeps the quality stable ad a higher quality.
And the p-frame will then be lower if there is for example a lot off "dark" shadow.
The i frame and p frame will be also lower if its out off focus or with fast spanning.

I only have a Olympus M.ZUIKO Digital ED 14-150mm f/4-5.6 lens.
So i have no idea how it works with other lenses, and how the bitrates responds, on the Olympus 14-150 the bitrate increase when zooming in...

By the way, in ETC mode the bitrate stays practically the same as without it... :)

mozes

Profiles, cinema, nature, vibrant and dynamic.
In Sony Vegas srgb to crgb color plugin added, thats all...

Nayche

@mozes For clarification, do you see this patch as something specially suited for capturing sports? I have to shoot a baseball video soon, and I am testing out various settings and patches as a brand new user of the GH2.

mozes

@subco i use sony vegas pro 10e.
A great free plugin for color grading is colorlab http://aav6cc.blogspot.com/

@Nayche not completely special, only the 720 mode.
Test if possible a lot off iso settings, high iso and shutter settings may not be any problem.

mozes

Oke thx @subco for testing.
What will push the i frames is this.
Encoder setting 1 720p=2 (use standard setting for encoder setting 4
Quantizer for 720 modes=1 (that give a more constant p-frame and a higher variable i-frame.
Also don't use the deblocking tables.....
The Scaling tables, i have no clue, but perhaps the standard GF2 settings give a better result

Howdy, Stranger!
