100Mbps Max Latitude Native 24/25p Patch
- Thread starter Lpowell
- Start date
I'm not really looking for ready-made firmware binaries, I would like to see the settings.
Couple of questions, I'm using one of the earliest EU releases of the GH1 body, mostly with the Pancake and Standard 14-140 lense by Panasonic;
- If I only record in PAL 25 fps FHD mode, does this patch still deliver reliable results when I also up the Audio bitrate to 256 kbit/s? (I know it won't be playable in the GH1, but I don't need that..)
- Is the Native 25p I'd get from this patch actually native 25 fps directly from the sensor, or is it still that 2 frames in one pack thing, semi-interlaced 25p that's actually 50 fps?
Speaking of that; What do these settings do exactly;
720p59,94fps->29,97fps=Checked
720p50,00fps->25,00fps=Checked
Could they cause instability, and if so, why?
- How much strain causes the use of the Video buffer=84.000.000 and why would anyone ever choose a lower value? Is it only battery-life suffering, or is it more than that?
- What exactly is the purpose of the Audio buffer, other than waiting to write to SD?
- Which settings in this patch should be left alone if I still like to shoot PAL 25p FHD and have it as stable as possible?
Thanks for the hard work.

I don't recommend making any changes to the internal patch settings in the 100Mbps Max Latitude Patch, as it will most likely reduce its reliability. Many patch settings interact in subtle ways that are very time-consuming to test, and the GH1's AVCHD encoder is not as robust as the GH2. It was very difficult to stabilize GH1 to work reliably at 100Mbps and I'm convinced that's close to its maximum sustainable performance level.
PAL FHD mode is always scanned at 25fps on the GH1. In the unhacked camera, PAL FHD produces interlaced 1080i50 MTS files that contain a 25psF video stream. In hacked Native 25p mode, the GH1's FHD mode produces non-interlaced 1080p25 files that contain a 25p video stream.
To my knowledge, there are no "strain" or battery life effects from hacking the GH1. Once a patch is correctly installed, the main issue is reliability.
Sorry, but that is the closed source method of working with patches, this way there will never be progress. I'm asking here because this (your) patch is not reliable at all in my GH1. I'm not at all interested in how the GH2 works, and I didn't ask for any comparisons either. Why do people keep ruining these threads with advertisements for different cameras?
Also, you picked values for a reason, and I'd like to know why you picked these:
Video buffer=50.000.000
Audio buffer=8.500.000
instead of for example
Video buffer=84.000.000
Audio buffer=11.500.000
which, as far as I understand their function, simply makes for more reliable interaction with the SD-card, but costs more power (buffering -using memory or storage- generally consumes enormous amounts of energy, I know this from designing extremely economic servers).
To be honest, your first post could use some more explaining per setting, because to me it looks like a marketing sheet rather than proof of concept or scientific test-results.
Boy for a person seeking information about work which has been shared free of charge which all of the community appreciates, you sure go about it the wrong way. I have no idea about your questions, but if I knew I would not respond. You need to rethink your approach in seeking answers to your questions.
Tried that road before, nobody answered. I reckon if that's the way it is, I don't care if the truth gets out about the 'secret ingredients' that are in some of these patches. I've been testing a lot myself (it's not THAT hard to do, by the way, only thing it takes is time), and after reading up on some settings it's clear to me that they can't influence others in any way. Some are said to be 'reliable' yet aren't, etc.

Do you demand to know everything about anything you get or buy?
Do you demand to know everything about anything you get or buy?
If you were to buy a car or whatever product, would you harass the factory with your questions demanding why certain parts are on it and specifically at those positions etc.?
I think, if you seriously read about those patches, all necessary information is there.
It takes no time to just grab a patch and use it.
If it is not what you want or does not do what you want, you are allowed to modify it yourself.
I would rather not do that to essential parts of my car, but I am smart enough not to drive a car at all.

What a miss for an analogy. First of all, this isn't like buying a car. It's a bunch of reverse engineered firmware patches that are all up for grabs to anyone with a GH1 and a hex-editor. Those ready-made patches are nothing but a collection of presets anyone with a text-editor can change, in fact, you even NEED the ptool to generate the firmware, so you can ALTER the settings you want altered.
And by the way, yes, I *would* harass the factory if the car had an incomplete manual without explanations.
The secret ingredients are testing methodology and engineering intuition. These are skills I developed over a 30-year career in audio and video technology and at present, I'm not recruiting for online apprentices. Your comments indicate that your own testing has not yet revealed some of the subtler behaviors and failure syndromes of the GH1. As I don't feel compelled to respond to harassment, you may have to rely on your own resources.
LPowell, I´m just shooting with the patch 100Mbps Max Latitud in my GH1 because I think will be the ideal to shoot with GH2 I´m waiting and panasonic 171 combo.
720p is 25p, do you think that unchecking the 720p 25p to get 720 50p will be at risk of get faills in some shoots? I really think that you patch is like that for a good reason, but just I was curious about it, just if want to get slow mo. I know I can put on another patch and solve this. Thanks!

Sorry, switching 720p mode to 50p in the Max Latitude Patch will most likely fail. I'd recommend installing the GH1 75Mbps GH1 Peak Reliability Patch since it's designed to support 720p50/60 mode.
Sorry? No way man! Thanks a lot for your amazing patches! Of course I got ready to jump in my GH1 the 75Mbps Peak Relibility for this situations! I was just curious but I could imagine your answer because you didn´t tell anything about it in you release for a good reason. Enjoying 100Mbps max latitud a lot!!

So I just picked up a GH1 (very) cheap and had bascily forgot everything about hacking.... but dude. Does this camera still rock!
One question though... when it crashes due to bitrate/cardspeed, I lost the file turning the camera off. If I remeber it right one just has to wait for a minute or so until the file is written before turning off? Cus I remember this happening when I used to hack my old GH1 and I didn't loose any files.
edit: Hmmm nope... file is lost upon a crash... trying with some other patches

With the higher GH1 bitrates, when you first hit record you can put your hand over the lens for a few seconds as this seems to prevent a crash. I suppose this would work with a lens cap also.
YMMV.

you can use a soft filter, diffusion filter or something else as well to break apart the fine detail to prevent crashes, works great. lpowell I believe suggested one in this thread or another and I found one that worked as well can't remember it but if you search around you should find the tests. If not just PM me and I'll look it up for you. I used the hand technique and it does not always work and can be frustrating when reviewing your clips through thumbnails... I've deleted a few thinking they were just junk video.
It's variable bitrate, film some trees with leaves and see what your results are. Use Stream Parser or Media Info.
