MJPEG FPS setting for Timelapse on GH2

    @kanintesova I haven't used wine in a loooong time so I don't know how much help I can be, but...

    GH13Timelapser is a batch file. If you ran the GH13Timelapser installer under wine and it worked, it should have installed GH13Timelapser to the wine path c:\Program Files\GH13Timelapser. You want to launch it like this:

    c:\Program Files\GH13Timelapser\GH13Timelapser.cmd c:\video\sourcefile.MOV

    Here's some tips I found for launching a batch file under Wine: http://www.linuxforums.org/forum/red-hat-fedora-linux/112720-how-run-bat-files-wine.html

    From the info on that page [and presuming your implementation of wine uses the same paths] it looks like you would need to make the folder ~/.wine/drive_c/video and move your video files there.

    @johnnym My basic understanding is that this would require such a major code rewrite to a vast number routines inside the camera that it would be nigh on impossible without help from Panasonic. Even just changing the exposure variables of the bracketing system was deemed too complicated a change to make given the virtual spaghetti of assembly code that exists in the firmware.

    One day a there'll be a forward looking manufacturer with an open camera system and a camera app store so people like Vitaliy can really show us what camera systems are capable of.

    For the time being though, I suspect the only ones who could afford to do this have a high-end market to protect and a monopoly on the high-end sensor technology. It might take an Apple or a Google to muscle in and make this happen.

    One day!

    I tested 3840x2160 in the MPEG settings. I think it is just stretching. I also test 160 quality vs 400 quality. I included a 100% crop of the 3840x2160 400 quality setting. 20 1.7 pancake - @1.7, ISO 640 (forgot to take off my .9 ND)

    Sorry for the crappy still life - had to do this under the bosses nose ;)

    Oh, and the 3840x2160 locked up the camera after recording, kinda scary.

    @Vitaliy - can AVCHD have a FPS setting of 2fps? Would be nice with some of the high-end patches for nice clean images.
  • DazzaDazza
    Strange my camera works fine at 2fps but not at 1fps, oh well. Is there any way to stop the recording of audio to further minimize filesize?
  • GH13TimelapserGH13Timelapser
    @Halvalla - It would be so much better if we could get clean 1 or 2fps footage in an AVCHD package - it is undeniably sharper than MJPEG and with an external power source and spanned files you could probably record for days if not weeks on a 32GB card. That said, the slowest shutter you can use in FHD mode is 1/30sec. 1/2 second only works in 720p mode when using AVCHD - so this problem would need to be overcome also. Sadly, I suspect it will remain in the too hard basket.

    @Dazza Correct, 1fps doesn't work. Neither does 5fps and some other settings. I would have based GH13Timelapser on 1fps footage if it worked. No way to stop audio recording currently.
  • izashizash
    GH13Timelapser, could you please post simple instructions on how to set the 2fps patch?
    Thanks.
  • jfrojfro
    Any suggestions on whether it would be wise to put the the 2fps patch on top of any of the 1 or 3 GOP settings?

    @izash - Scroll down to "How do I set this up?" here: http://timelapser.net/about/

    GH1: The fps is under "Patches for end users"
    GH2: The fps setting us under "Patches for testers"

    GH1 and GH2: The quality settings are under "Patches for end users"

    Using the presets people are posting here is probably easier.
    ,
    @jfro - Yes using this in conjunction with the custom AVCHD settings is fine
  • lolololo
    @Hallvalla lol, from your test i can see less macroblocking in the 1920*1080, specially noticeable in the black lens
    a pity though

    btw @GH13Timelapser thank you! for sharing your effort :)
  • izashizash
    @GH13Timelapser - Thank you!
  • stoneystoney
    beauty of @gh13timelaper's method is the smooth motion blur from timelapse. you can't get it from taking photos.

    GH1 - BLACKPOWELL
    hi
    I have the blackpowell patch on my gh1 now, only 1 card; 16GB class 10 card, how do i install the gh13 timelapse?
    do I have to erase the blackpowell patch in order to load the gh13 timelapse on my card and boot from there?
    just drag and drop the timelapse on my card drive?
    Thanxs

    @lowrider

    "do I have to erase the blackpowell patch in order to load the gh13 timelapse on my card"

    No. I believe the patch you are talking about modifies AVCHD and MJPEG settings. To record footage for GH13Timelapser you just need to modify the MJPEG settings on your camera to record at 2fps, so you can record normal footage with AVCHD and timelapse with MJPEG

    Open PTool and load whatever presets you like. Modify the MJPEG frame rate to 2 - you can use whatever quality settings you like, but I suggest those listed here [scroll down to "How do I set this up"]:

    How long can I take a continious timelapse video? I would like to make a timelaps of 3-4 hours but I don't want to click on record every 10 minutes because the file size reached its biggest possible size... Is there any solution on the video mode timelaps? Or do I need to use the regular methode for timelapse?
  • GH13TimelapserGH13Timelapser
    You won't need to press record every 10 minutes. At 1080p, quality 160 I get close to an hour usually.

    If you leave the resolution at 720p, then at quality 160 you might get a few hours - depending on the complexity of the scene.
  • LucLuc
    Thanks for that information.
  • White_WidowWhite_Widow
    @GH13Timelapser My first post here - love the spirit of this threat.

    I couldn't get your program to start using crossover on my mac, so I tried using premiere cs 5.5 instead. I set interpret footage to 25 fps. Looks pretty cool, but I am not there yet - not enough motion blur. I followed the instructions on your page and increased the MJPEG size to 1920x1080. The resulting file is still 1280x720. Not a big deal but I thought I mention it. Probably some mistake on my side...

    On the GH-2 in Motion JPG and I can't set the shutter to anything below 30. If I switch to AVCHD 720 I can set it as low as 25 but then I record at 50 fps.

    How can I get the beautiful motion blur and frame blending that your video displays? Any help is welcome.

    Thanks!
  • HallvallaHallvalla
    @White_Widow

    Do you have After Effects? Interpret footage to comp settings (in my case, 23.976) and then turn on frame blending.

    Just found this for Premiere:

    When frame blending is turned off, Premiere Pro duplicates frames to create the necessary interpolated frames. When frame blending is turned on, Premiere Pro averages the frames to create the necessary interpolated frames.

    Frame blending is off by default.

    Choose Clip > Video Options > Frame Blend.
  • GH13TimelapserGH13Timelapser
    Doesn't matter what frame blending you do in post, if you're shooting 2fps footage with a shutter of 1/30 you'll never get smooth motion on moving subjects.

    @White_Widow Make sure you're in manual focus mode - you can't select a shutter longer than 1/30 second otherwise.

    Not sure why 1080p isn't working for you - can anyone with a GH2 confirm that it works for them?
  • HallvallaHallvalla
    @GH13Timelapser

    What shutter speed do you recommend for timelapse at 2fps?
  • GH13TimelapserGH13Timelapser
    @Hallvalla Always 1/2 second shutter if you're planning to use frame blending so that the shutter is open for the full length of each frame recorded. Otherwise you'll get several ghost images of moving objects on each blended frame instead of one long streak.

    This makes a variable ND filter very, very useful. I suggest the Light Workshop's Fader ND - good quality and won't break the bank - apparently the mk.II out now is even better.

    Philip Bloom talks about it and more expensive filters in the comments here: http://philipbloom.net/2009/07/22/loving-the-fader-nd-and-singh-ray-vari-nd-life-savers/

    I shoot practically everything with 1/2 second shutter - just spin the variable ND filter around to obtain the right exposure hit record.
  • HallvallaHallvalla
    @GH13Timelapser

    Thanks, that makes sense. I don't have the FaderND, but I do have a .9 and a .6 that I stack if necessary on my panny 20 1.7.
  • tidatida
    @GH13Timelapser and @Luc could an intervalometer help to extent timelapse if it comes close to the 2GB limit. Maybe just stop it every 45 minutes and start operation immediately again.
