@humpman's the unreliable playback after taking 720p50/60 is similar to what @lpowell 75Mbps Peak Bitrate. Maybe this is an indication that you have done it right for 720p50/60 setting. Thanks, bro'! Your patch is sufficient for me to keep GH1 until 4K IBIS capable m43 camera price went down a lot.

I have tried the custom firmware outside ( great sunny day ) with sandisk extreme SDHC card, works great, great quality .

Keep up the good work @humpman !

to use the @humpman setting, put user.ini in the same directory as the ptool.exe

@tinbeo

user.ini has nothing to do with settings, it adds new patches to selection available.

Thanks all for helps. http://www.personal-view.com/talks/discussion/comment/224468#Comment_224468 Not only me confused of user.in. -;) I am on Mac, run P tool with Wine. When I load the firmware with humpman's video instruction, nothing is shown up in user setting. Will have to click on seta to shown user patch

@kanth those settings only for interlace, there is new setting to turn 2997i into 2400i(4800), and also interlace in GH1 it's just programm interlace so you can easely turn it to native in video edit programm. Native mode in GH1 is unstable.

@humpman thank you very much for the patches and video. very helpful!

@kbeezie i don't clearly underastand your problem, but:
Stock GH1 NTSC mode is 24p and it's packed in 60i interlace with 3:2 pulldown video file.
With "2997i to 2400i" 24p will pack in to 48i interlace without 3:2 pulldown file.
Can't see problem here.

@humpman using your user.ini and configuration examples I kind of 'mashed' this together using LPowell's 100mbps Max Lat patch as a base. ( https://pastebin.com/dpzYfp33 )

Changes on top of the Max Lat patch in pTools:

• Turned off native 24p wrapper
• Checked the Maximum ISO limitation removal
• [Motion Jpeg] Checked 720p30 -> 720p24 (drops every 4th frame to create a 24p result)
• [Motion Jpeg] Increase width/height for 720p30 to 1536x864 (from LPowell's 75mbps peak performance patch)
• Increased the H[32m], L[22m] and Overall[120m] bitrate as a suggestion by weimar ( http://www.personal-view.com/talks/discussion/162/gh1-100mbps-max-latitude-settings-v2/p3 ) , though in his example he kept overall at 108 and was using motionjpeg as a 18fps 1728x972 'silent film' kind of configuration keeping the original E#/F# table/quality settings. I also reduced the audio buffer matching his configuration (but kept it at 192kbit instead of 320kbit he had) as I mainly use audio on the GH1 to slate with my external recorder.
• Your settings from user.ini (The 3 Constants, Min QP, P/I Frames, and 2997i-to-2400)

Two Video examples against bunch of texture at ISO 100, 1/50th, and f/5.6 on AVCHD and MotionJpeg

And trying out ISO 1600/3200 with just the user.ini settings alone seems to be very very clean compared to just stock MatLat or 75mbps patch. (would post, but the example I shot is a messy living room lol, will get something tomorrow).

Tomorrow though I'm going to try to do some recording outside (maybe some heavy foliage if it's bright and sunny) though any suggestion of real world scenes to test it would be appreciated. But just learning about the 48i option from you has been quite nice for my workflow

Will do (though I don't shoot PAL, would using 24p/48i achieve the same purpose?)

PS: just did this ~10 min video (ISO 400, f/3.2, 1/50th, with "Smooth" film mode -2 sharpness, -2 contrast, -2 noise reduction, and graded in Davinci Resolve 12.5)

When I get to the campus later today, I'll do a controlled series of clips in the studio dimming the lights and what not.

(I also have an Breakthrough X4 10-stop ND filter to force it outside...)

Not sure if this is useful to you or not in the mean time.

In the studio with the lights off (most of the windows are blocked off) I shot the following at ISO 3200, 1/50th, f/2.0 in FHD did some pans, stopped on some darkened scenes, panned back, etc. Using the "Smooth" film mode, -2 sharp, -2 contrast, -2 noise reduction and I uploaded the MTS file directly to youtube.

the same at ISO 100 with the LED panels turned on and dimmed to 10% to allow for it to give me near the same meter reading at ISO 100 with all other settings the same.

edit

Looking back at humpman's example I re-did a static shot with the table layered with some texture/pattern.

I set the light panels so that I got roughly a half a stop to a stop under exposed on the meter and set the camera to ISO 3200, f/3.2, 1/50th, FHD, Smooth (-2 sharp, -2 contrast, -2 noise reduction) and uploaded the MTS file directly to youtube.

Just had shot short film with last settings from January 24

Hey @humpman and all who worked on and helped with this hack, just wanted to express my gratitude to you! I just picked up a gh1 again, (for 110 € plus the 14-42 mega ois, man what a bargain) on ebay as an addition to my 2 GH2s.

I got super excited over the last months finding and reading the thread and seeing that you got rif of the muddy compression in dark areas which finally got me to search for one again.

This is definitely the goto patch for the GH1 now, thanks so much! It will be my cam for experiments, light run-and-gun in good lighting conditions, experimentin with black and white and high contrast lighting, throwing it in the bag without holding back, b-roll and so on. Great little toy/tool to have, since i love it's picture characteristics.

@AlexGH1 great video though it's offline now, what happened?

All in all thanks to all of you and i hope you had a "geruhsame Weihnacht" as we say here in germany.

Best, MrZz
