GH1 firmware research volunteers required

One more notice.

...
Good news.

I now have G2 firmware from undisclosed source. All seems pretty promising.

Really stunning stuff here, thank you for what you've done for us! I love GH13

But GH1 only support FAT32, not exFAT, this limits single file size to no more than 4GB, which typically means video clip no longer than 30 minutes, thus make the removal of 30min limit somewhat lame. What a pity.

Is it possible to port G2' support for SDXC(exFAT) into GH13?

No emotions here, ok?

Your text is very uncorrect here. 30min is not related to 4GB limit.
As well as support of SDXC and exFAT do not mean support of files with more than 4Gb file size.
Any porting is, of course, impossible.

GH1
Bitrate Adjustment Simplified renamed to Bitrate Adjustment FHD/SH Simplified.
Bitrate Adjustment H Added.
Bitrate Adjustment L Added (both by jobless request).

GF1
Compare version ported.
Bitrate Adjustment FHD/SH Simplified patch (non-simplified version removed)
Bitrate Adjustment H Added.
Bitrate Adjustment L Added (both by jobless request).

Last two bitrate adjustment patches require usage of first one.

From now on, first "d" will be available and only after testing it'll move to stable state available on first page.

I currently use B) setting (stable in both FHD and SH), so I set H to 22 and L to 16. They are working as I expected. I got around 21mbps footage from H and 15mbps footage from L. Thank you, Vitaliy and a nice request, jobless.

OK, just tried it. I'm not sure how useful it is just to say: "It works" but, It works. ;)

I set:

1. Version Compare Patch (never used Version Change - ever)
2. 3rd party Battery (though I only have just the one Panny battery anyway )
3. Interface Language:: Anglish. ;)
4. Native 24p/25p
5. MJPEG 4:2:2
6. Bitrate Adjustment FHD/SH Simplified: 40,000,000
7. Bitrate Adjustment H Added: 38,000,000
8. Bitrate Adjustment L Added: 36,000,000
9. Overall Bitrate: 44,000,000
10. Limiting Bitrate: 48,000,000

And then took a crazy ~1.2min. video in low room lighting with a 2.8/45mm Tessar Zeiss in each of of the following modes:

More info later if you want. For now I must sleep.

But everything just worked! (I guess... the bitrates are low tho aren't they? shurg)

[GrgurMG]

But GH1 only support FAT32, not exFAT, this limits single file size to no more than 4GB, which typically means video clip no longer than 30 minutes, thus make the removal of 30min limit somewhat lame. What a pity.

AVCHD file spans on the GH1. Lot more convenient then having to wait a couple seconds to hit record again.


BTW..

Note to testers

I need to know TV modes (FullHD TV connected via HDMI to camera) while playing photos with various aspect ratios and videos at 50fps, 60fps, 50/60i containers, 24/25p native.
Please check your HDMI Mode menu setting before testing (must be AUTO).

Vitaliy, did you get ALL the data you needed from that? Finally got my Mini-HDMI cable today. I also have a HDMI capture card for non-HDCP video.. if stills or clips would be in any way useful to any testing.

[John Caballero]

John, it is clearly not place to discuss your understanding of my words.
PM me if you want to ask such questions next time.

As for my answer.
I don't know how you could interpret it as suggestion to make 12 GOP length.
Again - 24p patch changes GOP from 15 to 12. So, in 60i (without patch) GOP length is bigger. If you have problems in 24p you must input bigger GOP values in corresponding patch.

Sorry and thanks. I'll go away to another section now. Keep up the good work.

[fotosir]

Sorry I didn't notice that this thread is only for pure firmware development discussion.

And here is the test result of mine (3.36), checked:
version change (2)
version compare patch
3rd-party battery
interface language (english)
30min limit removal
native 24p/25p
video bitrate adjustment simplified (22M)
overall bitrate adjustment (24M)
limiting bitrate adjustment (26M)
audio encoding bps (384000)

Everything went OK during firmware upgrade, but after the upgrade, you can record video in AVCHD FHD or SH, but playback doesn't work, it said "motion image can not be recognized" or something like that, and you can't delete those video clips either. But the video clips work well on my computer.

Sensor m4 Adjustment 3 Test

I have redone my Sensor m4 Adjustment 3 test with the setting at "5".

I could not repeat the white balancing issue I experienced, so that was likely due to a testing error. So no noticable changes as of yet to report with the Adjustment 3 setting.

[GrgurMG]

Sensor m4 Adjustment 4 Test

MJPEG Quality Patched -> 384, 330, 300, 276
MJPEF Tables Patched -> 24, 24, 24, 24

Each adjustment tested in 4 conditions:

1) On-Camera Light On - ISO 320
2) Light On - ISO 1600
3) Light Off - ISO 1600
4) Light Off - ISO 100
-------------------------------------------------------------------------------------------------

Sensor m4 Adjustment 4 Tested with below settings

Set 1) 419
Set 2) 1676
Set 3) 838 (unpatched)

Results:

http://www.jerseyforged.com/sampleclips/m4_adjust4.zip

The setting 419 shows a static picture darkening on the bottom half of screen. Not noticable on chart in below example since it's so bright....



The 1676 setting showed no detectable difference from unpatched. Video showed no additional irregularies discernable from this test on any patch. Picture darkening was consistent throughout video in first test.

--- Update ---

Testing a Adjustment 4 setting of 209 caused the darkening to occur higher in the screen... 3 quarters up to be exactly.. so the effect is linear like the results in m3 Adjustment 1.

Testing a Adjsutment 4 setting of 0 shows the darkening (or lack of lightening) on the whole image. There's a yellowing as well, but that may be due to the darkening bringing out the color temperature of my background lighting.

Your text is very uncorrect here. 30min is not related to 4GB limit.
As well as support of SDXC and exFAT do not mean support of files with more than 4Gb file size.
Any porting is, of course, impossible.

I mean with 4GB single file size limit, with typical 17Mbps video bitrate, one single file can only contains about 30min's video clip.

With exFAT, at least you get rid of the hard limit of 4GB single file size, with FAT32 you won't be able to get a single file larger than 4GB.
