GH1 firmware research volunteers required

Guys, please read my notes to testers in last release post.
I need to know how two new patches work to move forward in AVCHD compression and MJPEG compression.

I hope that I'll make good site soon, so we could have special page and forum thread for testers.

As for 24p artifacts, and 25p better quality, it is not encoder problems, I think it is related to sensor scanning. 25p video can have better quality due to this.

I can not promize anything, as site requires very big amount of time, and so it'll be postponed until I'll find this time.
As for testers, in fact if you want to become tester just read my notes.
I don't want many testers, few smart and useful ones are enough.

One more note to testers

We don't need Bitrate Adjustment and Video Buffer tests.
Please read last notes about test we are interested at.
 
ptool observations

ptool observations

Note, just did the fw mod and even though I havent gone for the progressive native output but I have adjusted the bitrates I can no longer view the output in-camera! is this correct?

I see absolutely no reason that it would improve. It's not normally encoding 60 frames it's recording in a 60i stream with pulldown cadence. It's the exact same number of fields per second.

But there are several good reasons why native 24p would cause the quality to substantially improve... man, I gotta make time to dig into this...

Just put a little bit on the piggie, when is the G1 going to be purchased and how much do we need for the GF1?

It is up to Car3o to make is happen.
We could have purchased G1 long time ago, but seller was on vacation, now he is back, but I no longer see his listing.

720p/50 GOP =16

Looks very stable, audio bit rate 320k, all OK, but now cant view any videos in camera.
 
rolling shutter suggestion

rolling shutter suggestion

Hello everyone,

first of all I´d like to say GREAT JOB to tester13 and to you testing testers! Even the removal of 30 minute limiting alone is a huge improvement on the usability of this camera.

I have an idea I´d like to share concerning the rolling shutter issue "jello".
As it is only a limitation for vertical lines in fast pans or fast horizontal movement I recently thought, how cool would it be, if you could flip the camera 90° and get the firmware to flip the readout of the chip by 90° too. That way one could pan with that flipped camera as fast as you´d like just how one can tilt up and down right now.

I don´t know if that´s anywhere near possible but I wanted to share the idea with you.

Regards!
 
It means that!

It means that!

Now I have ticked the new 720p/50 and higher bit rates but didnt opt for 25p, I now cant view the videos on the camera lcd via review button. Audio is 48k320bps,

Videos look good;-) no mud that I can see in 720p but 1080p is still mud, will try progressive option later for 1080p. If modifying bit rates means I cant view the video anyway I may as well implement 1080p as well.

Not sure you're understanding rolling shutter entirely; you can't freely tilt up and down on a rolling shutter camera without consequences. The image gets stretchy or squishy if you tilt up and down. It leans side-to-side, but gets stretchy/squishy on tilt up/down. So if you read out the sensor sideways, you'd have the opposite effect: you'd get squishy/stretchy footage on pans, and leaning footage on tilts.
 
Tameside, I think what Tester13 means is what exactly happens when the camera fails to play the vid - does it freeze, does it just ignore the files, that sort of thing. Every bit helps.

Thanks for taking the time to help with the testing. Could you post some reference videos with the original firmware and the changed settings? It would be nice to find a place to post experimental videos along with the settings of the patched firmware... youtube, vimeo ... just a thought.
 
Tester13, quick question?

Tester13, quick question?

When I open the ptool for next mod, do I open the original 1.32 from Pana or my new 1.33 and what do I put in version increment 1 again or 2 etc?

Thanks

Give yourself some time to try and read before posting.
Question about increment is answered in hint.
And tool won't allow you to open wrong firmware.
 
Always work with the original files. Keep incrementing the number to get a higher version for the camera to accept it.

You last post was not clear. You say "I now cant view...".
Which is it - can (yes) or cannot (no)?
Thanks for testing and good luck.
 
talked t g1 seller this morn, he has them relisted,going to purchase today. secondly, talked to solomon, waiting for his reply. all is well in the purchasing world.

and for the record those who are using the 24/25p patch

damn, didn´t realize that. but of course it makes sense, I just never encountered it so far as I obviously don´t tilt up and down often enough :)

Would you say that there is more tolerance to the viewers eye with the stretchy/squishy footage than with the leaning? I yes, it would be still a bit of an improvement to be able to flip the cam.

Perfect, thanks very much for your efforts!

:) We'll try to prevent this in the future.
I am thinking to prevent 1080p viewing if this patch is used.
 
Important thing

We really need Panasonic Cross-Assembler and C Compiler (evaluation versions are ok).
I found only DebugFactory Builder at http://www.object.co.jp/panamc/panamc_eng/download/am3stk-soft.html
But it is just IDE, it can not compile anything.
Each AM3 based Panasonic controller board have CD with serial number, I just need this serial number.

If we could make patches to be activated by simple file on SD card, it could speed up whole process very much.
We do not know all necessary functions good enough yet (I know how to open file to read, read part of this file, and may be close it, but not all parameters and not all details).
