@Butt FYI - I just tried those settings you posted (sete.zip), minus the PAL/NTSC switch and 30 min limit hacks (I have an NTSC GH2). When shooting my standard test (speaker grille - always pushes codec to max bitrate), 720p AVCHD (SH) would lock up the camera immediately with a card not fast enough error. Resulting files were 0 bytes. I had gotten the card too slow error before with 720p, but never had it locked up the camera and had always written at least a few seconds of video.

Chris ..

Good point .. the Transcend Class 10 20Mbit .. was new and not formatted.
FYI: I am testing with 3 cards, the 20Mb Transcend and 30Mb and 45Mb Sandisks.

I like the broken frames at the beginning .. I started as 16mm editor :)

Anecdotal bitrates and SD cards.

Aplogies if not scientific enough. I have tried a variety of Kae and Butt settings at both 43Mbits and 65Mbits. All for me are useable .. couple of artefacts at the beginning of each clip, some wierdness in rear LCD panel.

The only other thing I consistently observe is that the first time I attempt to record with a Transcend, I get card error, 2nd and consequent attempts work. Sandisk 45Mb works perfectly for me.

Example:
load 42 and35Mbit stable settings.
Set camera on Tripod at contrasty speckled carpet half bright sun half shadow.
Attempt to record at 42 .. card fails
Attempt to record again .. records fine
Switch to 35Mbits FH/FL ... attempt to record ... card fails
Attempt to record .. records fine.

This goes on ad infinitum .. everytime I change recording quality menu, first attempt always fails .. 2nd is fine.
Apologies for lack of scientific method
I tried it two days in a row.

I get the same symptoms with the MJPEG settings by Lpowell.

This is not a complaint, an observation that may point to something the camera does.
I can only speculate that the camera might write something to disk with every format change that just overloads the speed of camera/card

@Butt what is the GOP and mbps at 24h on the above patch?

Hello,

i have a little question about the settings (i´m a noob...) . I have pulled the bitrate for 720p50 from 16 to 22 000000 and i think the colors are better. But i dont understand the GOP settings ? which GOP Settings are the best for me ? And now i need a good compromise that offers me mixture of datarate and image quality.

( I use the 720p50 mode of the GH2 becouse of the good image quality AND the good motion qulity, the 24p Modus is to stutter, if anyhone has some googd advices, your always welcome )

regards Natalie

need help. I tried many kinds of attached patch from here. No problems with the camera. But the Bitrate of the most AVCHD(24H&FSH) files I imported to Final Cut Pro X with no optimized and the original MTS files are around 10mbps~18mbps among them. Only few of them will be around 40mbps~50mbps when i use the 60mbps GOP3 patch, and none of them will over 30mbps if i use the suggested setting with nothing else touched. 24L&FS are around 8mbps suggested setting......

My card is Sandisk Extreme 32g HD bought yesterday works great with the 100Mbps 1080p30 patch. When I don't know how to fix AVCHD bitrate Problem, I revert the camera to the Original settings. The AVCHD files bitrate are still 10~18mbps in 24H mode!! I tried my Transcend 32g class10, the result is the same. So I don't think it's the problem from card.

it is really unhappy to see the bitrate is 11.xxmbps :(

Please Help!

Same here, no problem with Kae's last setting (60mbps Gop 3 in 24p) using Transcend 16go class 10. Footage of crowd and moving subject (subway and Paris by night) looks awsome, even at 1250 iso (!)
Play perfectly on mpc AND VLC on my platform through (i7 Sandy B., GTX470, 16Go Ram).

Greetz fly to Vitally and all testers (scuse my french !)

With my Transcend 16Go class 10, 60mbps GOP 3 is perfect. Much better than 42mbps. Actually, the bitrate is about 52mbps in 1080 24p. But, I can't read it with VLC.

"@towi - use ini files, zip them and attach to message."

done

@Butt
Problems are mostly related to some software that can behave unpredictable looking at strange parameters in your clip :-)
I am working on a fix (it is not hack bug, we need to change original code to make it work as intended).

@Butt

I mean any bitrate number 24H or any other mode.
All things that are over this limit could result in internal overflow and strange behaviour (sometimes) as result.

@Vitaliy_Kiselev
>Good advisement.
If you want really stable stuff, keep bitrate settings below 32Mbit.<<br />
you mean bitrate 24H and bitrate FSH/SH settings below 32MBit?
