Beginners: Basic hacks questions

  • @Zoke I regularly record documentary interviews on Driftwoods AQuamotion patch (100 mbps, and it spans). You should get about 25 minute record time on a 16 gigger. Find it in the patch vault. If you're not a GOP1 addict, you can also find some excellent GOP3 patches. That said, I'm in 24p land, not PAL so not sure if AQuamotion is what you need.
  • @marktottymy your best bet is to play around with settings from the patch vault and built up from there. Refine there settings if you can, but you're not going to reinvent the wheel at this point, so spare yourself the hassle and play around with existing patches.
  • I should have added that bit of info at the very least. I'm using the GH2. ;)
  • What camera are you using?
  • Patch question. I'm starting on a documentary this week and I'm looking for a patch that's a bit middle of the road because I don't want my 16GB cards to run out in the middle of an interview. Which patch do you guys recommend for 15 minute interviews recorded in a PAL country? Thanks in advance to anyone who bothers to take the time to answer this question. :)
  • Anyone who knows the link to the thread which says about "cadence" problem?
    I always read the word in " the official low gop topic" but I don't know what the word means.
    any hint will help me. thanks in advance.
  • Anyone knows every GF1 are hackable?
  • @nomad
    Done the tests, different location, same conditions, moving camera moving person, images look perfect, no disturbing lines. Local card writing problems? Or location (hospital close to bed and electronical medical machines, may strange inductions?) Cheers
  • @Vitaliy_Kiselev

    So how we understand which G2 is hackable and other is unhackable? Because I guess the G2 is not enough to buy without hackable features.
  • @jamesjay

    G2 since some time are unhackable as I know. It is quite long known fact.
  • Hi! I'm about to get a new G2 but I read something about some new G2's are unhackable. Some says its all are hackable. I'm confused. I need some help about this. Thank you!!!
  • @nomad
    thanks, yes, that could be the answer. Will do some testing today and let you know. Definitely it has to do something with "movements or motion", regarding camera or action, in these moments some element is "stressed", thats for sure.

    Q>If you hack the GH2 say with the 172mbps patch, will the camera consistently record at that bit rate no matter the subject matter, or will the camera only use that horse power if it needs it?
    A>The camera will only use the bandwidth that it needs (to provide detail dependent on PTool settings)- up to 172mbps - normally I have found the bit rate to be steadily >100mbps.

    Q>If the camera only uses the horse power if it needs it, how can one explain the overall better picture quality when comparing the 42mbps patch to the 172mbps patch no matter the subject matter?
    A>Because 42mps patch is also the 'max' that it can achieve. (max 42 is lower than max 172)

    Conclusion: AVCHD is a variable codec- this can NOT be changed- the hack forces AVCHD to keep more detail - where it would normally just throw information away. (this is called a Lossy Codec) All codecs that are not 'uncompressed' do this- even raw.

    Anyone have a better answer? (The 172mpbs popular patch is Reacquainted- there is LOTS of stuff going on there not only bitrate- also Intra GOP etc- like anything since 1997: Google is your friend)
  • If you hack the GH2 say with the 172mbps patch, will the camera consistently record at that bit rate no matter the subject matter, or will the camera only use that horse power if it needs it?

    If the camera only uses the horse power if it needs it, how can one explain the overall better picture quality when comparing the 42mbps patch to the 172mbps patch no matter the subject matter?

    Hope this make sense, thanks in advance to anyone with any useful information.
  • If it's just a horizontal tearing of the image, that's normal an a computer. No computer screen can handle 24p, only some HDTVs. Most computer screens have 60 Hz (or more).
  • @rbna Do you know what AQ is for? I know it stands for Auto Quantizer but what does it do?
  • @Macalincag
    Thats what I did when I did "log and transfer" into Final Cut, I reckon? I imported it, converting into ProRes 422 (HQ), cheers
  • @gameb

    Transcode it to Prores HQ or something similar and see if the problem persists. It'll be playable and will look like the original. If the image looks messed up in the transcoded version then you know those "disturbing horizontal lines" were really captured that way...
  • Thanks Macalincag, I have a Macbook Pro 13", 2.3GHz Intel Core i5, 4GB. Can see it playing on MPlayerX and also on Final Cut. I checked it on the camera right now, cannot really see it, but cannot make sure its not there. Its too small.
  • @gameb

    Do you have a good computer? Is playback like that within the camera?
  • thanks nomad, yes, I am shooting progressive. 24H, nostalgic mode. May be horizontal disturbing lines is the wrong description. Its not aliasing. Its like when I do a pan, certain images are like horizontally "broken". Like in old video times with old tapes. Sorry I dont know the precise technical term for it. Same thing happens if there is normal slow motion action in the image. If the camera and the action dont move, everything is fine.
  • Horizontal lines? Are you shure you are shooting progressive?
  • I have set the camera on the 44Mbps settings with AQ on 3 (most on details), but have disturbing horizontal lines on normal camera or action movements. ISO 320, Shutter 50, nostalgic all to -2, SD-Card 16GB lexar prof class 10 20mbps, do I have to change the sd card for a faster one or change the settings for AQ (maybe to 2, some to details)? Anybody has other ideas or experiences with that issue? Thanks for helping.
  • @gameb

    ".ini files" are patches. He's suggesting to just download some which set the parameters for you.
