MJPEG FPS setting for Timelapse on GH2

    @jfro why you don't use the gh13timelapser before editing/grading ? After several tests it's seems that you can't record files larger than ~2GB (~1H20 with my settings) in mjpeg, after that the recording stop.

    @GH13Timelapser or anyone who has the answer
    I am not sure I understand why I should use 1/2 second shutter. I plan to shoot a timelapse of a parking lot filling up starting at dawn. Won't a long exposure cause extremely long streaks from the headlights of moving cars? Also, what do you recommend for exposure as I will be starting in near darkness and ending with full sun up. Would some type of auto exposure be OK.

    jfro: Use GH13 Timelapser at http://timelapser.net - this is exactly what it's for!

    It outputs footage at 25fps, but just conform the footage to 24fps on import.
  • GH13TimelapserGH13Timelapser
    @Jspatz It's necessary [or at least recommended] if you want to use the frame blending in GH13Timelapser as otherwise you'll get multiple short light streaks in each blended output frame.

    What you would typically do is shoot 2fps with 1/2 second shutter, then throw the footage at GH13Timelapser with settings like Interval 8 | Shutter 4. What this does is make one output frame for every 8 input frames and it will blend together 4 frames to do this. This will give you the same shutter speed to frame rate ratio that is commonly used for film - with the shutter open for half the length of the interval between frames [24fps film is traditionally shot with a 1/48 second shutter]

    If you're sure you're not going to want to use frame blending then you might want to use a shutter speed of 1/4 which will give you the same ratio. Any shutter speed that is significantly shorter will prevent the light streaks that you mentioned, but tends to look like a stream of pictures instead of smooth motion.

    @greenbean, I started a new topic for AVCHD 1080p time lapse photography:

    I have used GH13 timelapser, but haven't figured out how to output a uncompressed file or a 422 file.
    Reason for my question is if I want to do some color work or any editing on the final movie, I'm out another generation which I don't want to do manytimes.
    I'd like to take the g13 timelapser output and then edit it without a compressed generation loss.
  • jfrojfro
    DUH, what an idiot I am. Just looked at my output from the timelapser prog and it is AVI. Why did I think it was compressed before. Sorry for the posts. I should pay more attention.
  • astrabanastraban
    I'm not sure there is any compression : the tool just discard some frames (depending on the chosen interval) and blend the remaining one if you chose to (shutter setting)... What you have is loseless mjpeg frames in .avi container - which doesn't allow same amount of grading than proper raw pics... But @gh13timelapser can explain the exact process if i'm wrong...
  • astrabanastraban
    Well... Problem solved. :-)

    @GH13Timelapser

    Have you experienced the GH1 freeze-frame for a few seconds then continuing?

    Every few minutes it seems to hang for a while, then resumes.

    hello everyone
    really the timelapse feature, but i have a quality problem. i attached a jpeg capture of my clip that i edit with Premiere 5.5, (interpret footage, frame blending, speed up) but i get this from the footage, see the blue in the sky. what can i do to improve this ? many thanksimage

    Hi @GH13Timelapser and otherz! Thanks for brainstorming share!

    I found really practice to shoot with this tweak, but concerning setting i have a question...

    If i have well understand, there are a maximum of near 750 lines 'usable' in mjpeg of gh2.
    So i think 720p is the optimal setting for both HD and VGA (until you haven't the time to transcode in 1080p in post, at the sacrifice of short length timelpase - 2g limit).

    So in the feeling of the quantum patch of Dr Driftwood (top quality but short recording AND usable quality and long recording), i have try to set the recommanded setting for VGA (Quality 160-140-120-100, all table 4) and a doubled setting for HD (320-280-240-200, at 4 too)... All in 720p.

    It's a correct approach for hq mjpeg?

    Edit: with my HD setting i reach near 30 minutes of recording (at near 9Mb/s). Just have do the test.
    Edit2: and one hour with my VGA setting (at near 4Mb/s)...

    Correct me if i am wrong, but when you are in VGA and change it to 720p, it's a real 720p or it's upscaled 480p??
  • EtbEtb
    Yep. Ok i got an answer. VGA upscale-stretch over 480p...
  • jeffryalanjeffryalan
    tried to get Timelapser to work on my mac using Wine and Crossover (ptools working fine with those) but it wouldn't work for me.

    Anyone have a suggestion for optimal workflow on Mac?
  • EtbEtb
    @jeffryalan

    Timelapser take a lot of processor ressource so i recommend you to run your win os in a performance way: native bootcamp for huge files to treat, and via a vm soft for shorters..
  • lowriderlowrider
    yes I have the same trouble, Mac- wine , ptools launchs fine but timelapser does not, I tried several ways, comand line, all!
  • JDNJDN
    For anyone wanting to add timelapser to your favourite GH2 patch, here's the simple way. First, load any of the patches here with timelapser. Then load your favourite patch -- so long as the patch doesn't mess with MJPEG settings, the timelapser MJPEG settings will remain intact, you just have to go back and check them to turn them on.

    Apologies if this is old news, just figured it out when trying to move timelapser onto aquamotion so thought I'd share.
  • ChhatrapalChhatrapal

    I am using this for a while now ... i have noticed 30 min limit on my 32Gb 30MB/s sandisk card ... Is it because of 2fps setting or complexity or because original 30 min limit applied on the original Firmware ... How can i do ... say 2 hr time lapse shoot?

  • duartixduartix

    @Chhatrapal It's probably this: http://www.personal-view.com/talks/discussion/comment/36956#Comment_36956

    Hi guys, thanks for all the love you guys put into the GH2. Panny should acknowledge the work that's being done here and for moving so many of their GH2s out into the world. We really can't thank you enough.

    I'm just trying out this time-lapse thing on my camera but unfortunately can't install the timelapser app on my Mac. I'm working in AE for now. Anyone managed to solve this?

  • tidatida

    Please find in below link a similar method of that what @GH13Timelapser has done for MJPEG. Tis method is able to handle AVCHD Timelapses.

    @Vitaliy_Kiselev Just like @stockhausen I'm chomping at the bit for GF1 Xfps. I'd like to humbly add to the request for supporting the GF1. Thank you excellent sir!

  • stockhausenstockhausen

    @Hwulex , hi there,, Yes, after donating towards it I was marginally "miffed" as they say here, that pTool 3.64 didn't implement GF1 2fps,, BUT considering the crazy amount of work Viteliy had gone to It wasn't surprizing PLUS I had the foresight to invest in cheap GF2 body last dec and that does the 2fps beautifully so my Miffedness lasted mere seconds, if yr impatient and have £150-£170 to spare go GF2.. chomping at the bit will only wear yr teeth out :]

  • rickerricker

    Can someone point me to this mpeg timelapser patch, without anything else. Just the mpeg changes, i'm worried if I use the Cbrandi 44mbs + timelapser, it may miff up some other settings i'm unaware of. (i.e how do I know driftwoods patches replace every setting of Cbrandins?)

    So the solo timelapser mpeg settings patch would be very helpful!

  • Dusty42Dusty42

    All, What is the bit rates you are all getting at 2fps in mjpeg mode? I am getting only 6 to 7 Mbps. If I remove the 2fps setting, I will get about 50Mbps. I patched the 720 mjpeg mode to 1080 using the Low Light setting. I double checked my settings and reset the camera after patch. I also reformatted the card.

    Here are the settings that I use (by LPowell):

    720p30 width=1920 720p30 height=1080

    E1 Quality=400 E1 Table=24 E2 Quality=200 E2 Table=36 E3 Quality=175 E3 Table=48 E4 Quality=150 E4 Table=4

    Thanks

    Sorry. I figured this one out as follow:

    1. Total file size/clip's length, this gives me MB/sec.
    2. Convert MB/sec to kbps (1MB = 8,000,000 bits)
    3. Sub the audio bit rate from #2

    I was a little confused that the values of E1 through E4 set the bit rate like in AVCHD. But I think the values for E1 through E4 are different.
