Hi there fellows!

I was messing arround with GOP settings in my GH13 PAL version, so is 25p in FHD.
I see that default value there in PTool 3.36 is "13" and in SH at 50p is "26", right the double.
Iīve proven SH 50p GOP with value "13" instead of itīs default value (26) with sucses! and there are not spikes at all in the recorded video signal, but when trying to change FHD value wich is "13" comes the question:

Anyone knows a nice and stable value for FHD to achieve a lower GOP group than the default value in a PAL GH13 version?

Thanks in advance!!
Asier.

BTW: I,ve been using "c" quality setting on PTool 3.36 in AVCHD mode with 24/25p activated....

Default for 24p is 15, I changed it to 12 with success. Choose an interval of the FPS and you should be ok. The footage I got when i changed it to 12 was astounding, especially with all the high detail and movement.

24p patch changes GOP from 15 to 12 If you are getting astounding footage you don't need to apply the GOP patch :)

Hi Joe!

Thanks for your fast and detailed answer fellow! much apreciatted!.
Iīve tried yet two values for FHD on a PAL GH13, as follows:

FHD ---- from 13 to 8 ---- This value made The codec compress de image ALOT so was crap! ;-). "C" values on AVCHD.

FHD ---- from 13 to 6 ---- This value looks like works preety well with "C" values on AVCHD.

I liked to know otherīs experiences on this matter!.

Thanks again for your entry Joe!

Didn't know that. I put the Native 24p patch in, and then manually changed it to 12 in the other section. does the same thing. It all looks great though, and you know what that's all that matters.

Joe, can you please download StreamEye http://www.elecard.com/download/ (30 day trial) and post the screenshot. It should look something like this http://www.dvxuser.com/V6/showpost.php?p=2020646&postcount=524

Oh, yeah. Class 4 won't be able to handle it. I would suggest either:

a.) seeing how far you can safely push it (I'm happy with my footage and couldn't make the camera freeze up, so I'm done with patches)
b.) going out and spending money on a nice Class 10 memory card. I bought the 32 GB Panasonic Gold, and I love it.

Yep, will do as soon as I can. I'm going to the beach on Sunday, so I'll shoot some nice footage and put up some stills. I just don't know when I'll have the time because I will be really busy with work. If someone tells me what files (as in what files off the memory card) to put up a file Sunday night. Just be aware it would be a short clip and not everything I shoot.

I am using 24p patch as well. I chose 8 because its 1/3 the frame rate. Where your scenes highly detailed? I have had no problems with pulsing or mud even with detailed scenes.

Thanks. The MTS files are located in \PRIVATE\AVCHD\BDMV\STREAM folder on the card.

Hey Nubins!
The detail in my scene was not very high detailed nor low detailed...
