    @JPB1138

    It is as Chris having described the merit of GOP3. Although GOP1 is ideal in respect of being various, it is impossible to use the big I frame physically. Since the big I frame naturally has much amount of information, there is a merit to high IQ. On the other hand, in LongGOP, since there are few I frames, there is a demerit about the reproducibility of a motion, and especially the reproducibility of a noise. I think that GOP3 may be one compromise point of the motion, the finer noise pattern and IQ. Of course, GOP6 may be also. However, although MY EYES hardly understand the difference in the motion of GOP1 and GOP3, or a noise, the difference of GOP1 and GOP6 can be checked. Therefore, I have stuck to GOP3. :-)

    vstardust, after switching between NTSC and PAL you need to power cycle the camera, and then reformat your card, or switch to a different card that was formatted previously with the NTSC/PAL setting you want. This is covered in the FAQs (link at the top of this page).

    Combining one person's settings for one mode with another set of settings is tricky, and not always possible due to the fact that different modes share some firmware parameters.

    Hi and sorry for making new post, because I think that answers to these question could be found somewhere from this forum, but I have quite severe arthritis and it really hurts to use my computer right now.

    Bottom line is that I just got my new GH2 and I would like to use 1080p25fps for regular shooting, 720p60fps for slow motion, 1080p24fps for movie styled clips and 2/2,5fps for timelapse.

    I downloaded Cake v2.0 (only one file (GH2 Cake v2.0 - setc.zip)) and got it working. Problem is that when I try to change from PAL to NTSC for 760p60fps I get error "CANNOT RECORD. FILE NUMBER EXCEED LIMIT". I have tried resetting file numbers but it doesn't help. Can I swap between PAL and NTSC easily or do I just have to use 760p50fps instead?

    Another question: I would like to add "2.5fps AVCHD 24h Timebuster/TimeHBusteR 2.0 settings - The day is not over!" to my Cake v2.0. Is that possible? Do I understand right that I have to sacrifice one of the Creative modes for that? HBR or Cinema? Can I just "add" it to my Cake v2.0 on Ptool and they both work without problems?

    I will make a nice donation as soon as I get my camera working stable. Thanks.

    Yes, with GOP3 you can get bigger I frames, which will offer better gradation rendering, etc... The main advantage of GOP 3 (at least for me), over say... GOP 12, is that GOP3 will span with much higher bitrates than GOP 12. LIkewise, GOP 6 also spans with higher bitrates than GOP 12.

  • JPB1138JPB1138

    @bkmcwd or anyone, that uses GOP3! Thanks!

    What are the advantages (if any) to shooting in GOP3 like GOPzilla or natural, GOLGOP3, etc? as compared to GOP1 hacks like driftwoods (quantum, sedna, etc.. Only referring to 1080p24p..

    Mainly looking at quality of motion and detail/resolution. and possibly night time shooting? Ive only ever used driftwoods stuff, but just looking at other settings... to see why people would choose GOP3.

    Is there anything that would make GOP3 BETTER than GOP1 codecs?

  • jackjack

    @stray thanks for that precise rapid response. Makes sense now, and there i was actually looking into the GH2 official burst mode thinking this had been modified lol.

  • StrayStray

    @jack There is no way to activate it, its just a different setting to download and try. Its called burst mode because its likely to only work for very short shots before it stops with a write error.

  • jackjack

    hi guys

    I'm a bit confused as to the GH2 burst mode. I love mysteron v.1 and also want to really test this new burst mode version. Please could anyone briefly explain the burst mode and how i activate it.

    Is it 24p mode or stills mode?

    Sorry if this is basic question.

    This is my first test of the Mysteron v.1

  • RamboRambo

    Brian, shoot it unhacked, it is still good quality.

    @Brian_Siano Try Flow Motion v1.11 or SpanMyBitchUp v2b on the 24L setting.

  • Brian_SianoBrian_Siano

    I have a beginner's question about setting the bitrates in my GH2. I'll be shooting a live event, and it will run to close to two hours. I'll be using the Cake patch, which was recommended in another thread about covering concerts. But, the Cake patch sets the bitrate at 70mbps-- which gives my 32gig card only about an hour's worth of recording time. I'll also be editing this footage with stuff i shoot with my TM700, which shoots at 28 mbps.

    So I'm wondering about lowering the bitrate on the Cake patch to something lower, to gain more recording time, and to make a better match with my camcorder footage. If I take the Cake patch, and simply lower the bitrate to, say, 42 or even 30mbps, will it affect anything else-- like the camera's ability to span files for long takes?

  • gamebgameb

    Why does HBR only have a high bitrate setting? Normally we have a higher and a lower setting. Is that may be changeable?

  • mattherematthere

    @jrd The sandisk 30mbs cards are pretty fast, you should have no problems running just about all settings available, I have the Extreme one myself 30mb/s (not the Ultra) and I've not had any issues.

    There are 64gb 95mbs cards that you will find, being spoken about here, these allow spanning (continuous recording) on some settings, but with the 30mbs card you will be able to use all settings just not span on the very high bit rate ones, hope this helps :)

  • jrdjrd

    Has anyone tried Sandisk Ultra (Class 10, not 6!) 30mb/s cards? If so, please specify what settings you were using and the results. Thanks.

  • mozesmozes

    @jaapb nee je kan gewoon renderen naar 25p.. gewoon een clipje van een seconde of 30 gebruiken om wat export settings te proberen...

  • arvidtparvidtp

    @trialboj to update to plain vanilla firmware 1.1, just put the .bin file on the root of you SD card, put it in camera (use fully charged battery NOT ac adapter), start up and press play within a second or two of starting up, then follow update menu. To apply a hack, you'll need ptool and that firmware file and some good settings file(s) from this community, or do your own simple hack by increasing bitrates)

  • trialbojtrialboj

    I want to update my gh2 firmware, i have downloaded the new firmware GH2__V11.bin, where can i copy it?

  • JaapsbJaapsb

    Sorry Mozes, our posts crossed..

    Ok, I am going to try With that codec tommorrow..

    Trying all settings at the moment, strange thing is, you can import 50p in Magix, but can not export as 720 50p, only 1080 50 p.

    And one other question, I almost don't dare to ask: but when exporting 50p clip, as a 25p, I have to double the speed of the movie first?? To get no slow motion..??

  • mozesmozes

    try exposureroom

  • JaapsbJaapsb

    Ok, so I assume I have to try 25 fps as being 1/2 of 50p.

    I already used my weekly hd upload on vimeo, so have to use Youtube, and reading they only take 30 fps... .??..

  • mozesmozes

    @jaapB i agree with @mpgxsvcd abouth the rendering settings
    Pal is exact 50 fps, youtube/vimeo re-compress it exactly to 25 fps, i have no problems there ( i also use pal).
    Just checked the magix page and i read this.
    Ondersteunde exportformaten Video: AVI, DV-AVI, MJPEG, MPEG-1, MPEG-2, MPEG-4, QuickTime™, WMV(HD)

    The best option you got is (ad least thats what i am thinking) is to use QuickTime™
    Download the DNxHD codec here http://avid.custkb.com/avid/app/selfservice/search.jsp?DocId=423319
    You get big files and a some flatter colors, you have to play with it to find the correct setting, but the quality is realy amazing.
    Just take a short clip 30 seconds is enough.
    Take a clip with a lot off color and movement in it, let the codec in magix work.
    And render that clip with different settings in DNxHD, and compare them..
    youtube/vimeo and exposureroom don't have problems with DNxHD, after upload you get a mail with the message you did use i very high unnecessary bitrate, they give you tips on howto setup for online video, just ignore it.

  • mpgxsvcdmpgxsvcd

    @Jaapsb

    I think PAL is exactly 50 FPS(Someone please correct me if that is not accurate). I don’t work in PAL formats often.

    Just slow the video down by .5x. Your editing software should give you the option to slow it down. If not then you could also use something like twixtor or virtual dub to do it and interpolate frames.

    Just doing the normal slow down should work though.

  • JaapsbJaapsb

    And btw, do I need to slow down the clips in post editting, or only give desired fpv when exporting?

  • JaapsbJaapsb

    @mpgxsvcd

    Ok, thanks, I shoot in 720 50p not 60P , PAL I also tried to export in 50p to vimeo, but was looking the same.

    I am using Magix video deluxe 17 for editing.

    I will have a look, if I can Render it higher, but at which frame rate exactly, because I shoot in 50p??

    Thanks, really great I am learning a lot, the frames per second thing is not the easiest thing to understand.

  • mpgxsvcdmpgxsvcd

    @Jaapsb

    Good first attempt. Everything you need is still in the original data you captured. It just appears that your editing was not up to par. I assume you shot 720p @ 60 FPS. Youtube can only display @ 30 FPS for 720p video.

    You need to slow the video down to ½ of its original speed. That will preserve the 60 FPS you originally recorded but conform it to a frame rate youtube can handle.

    Also you way over compressed the video. Even youtube video should not look that compressed. You have completely and utterly wasted any benefit that the hack gives you. Try rendering the video to very high quality H.264 in the 24-40 mb/sec range.

    I can’t wait to see what it looks like once you slow it down and get the compression figured out. It looked cool it just had too many artifacts and it was a little choppy. Make sure you render to 29.97 FPS for NTSC video and not 30.00 FPS.
