    Panasonic GH5 & V-log

    Hi,

    I appreciate that this is not the right forum for the following questions, though good forum recommendations would be welcome. 

    Ok, so I am thinking of purchasing the Pansonic GH5, as it is now time to get to grips with my camera phobias, and this machine has had rave reviews.  But so far all the tutorials on youtube reference Premier Pro as somehow the complemetary suite (my phrasing).  Does it work well in MC?  Does it shoot in DNxHR?  What about the Ninja Inferno screen/recorder (10-bit colour)?  And can anyone give pointers as to what v-Log is all about, and any other recommended comparables relating to flat/vibrant colour footage?

    Thank you,

    DC

    Follow my MC Diary to see updates for GH5.

    It's a wonderfull camera. Maybe the best I had so far.

    Except from the 72Mbit HEVC which is still not supported anything other plays good.

    P.S. I would use HLG profile from now on as V-Log needs much work (unless you are not on a tide shedule).

    If you can buy GH5s it's better on low llight. However the 20mpxl of the GH5 gives a lot better stills.

    If I would buy today I would probably buy the GH5 again over the GH5s.

    Hi,

    I appreciate that this is not the right forum for the following questions, though good forum recommendations would be welcome. 

    This is THE forum for everything with helpful people.

    Ok, so I am thinking of purchasing the Pansonic GH5, as it is now time to get to grips with my camera phobias, and this machine has had rave reviews. 

    And it did well. Remember that this is a serious machine even if it's relatively cheap.

    But so far all the tutorials on youtube reference Premier Pro as somehow the complemetary suite (my phrasing). 

    Because Premiere is easier to edit on but not trusted for serious work FROM ME.

    Does it work well in MC? 

    It does. Except the HEVC codec... yet.

    Does it shoot in DNxHR? 

    No, it's shoots mp4 and mov (which is mp4) and lower bitrate AVCHD.

    What about the Ninja Inferno screen/recorder (10-bit colour)? 

    I don't need it as this little machine can shoot INTERNALLY 10bit 4:2:2 in HD, UHD and C4K.

    And can anyone give pointers as to what v-Log is all about,

    It's a flat profile (but noisy as the lower ISO is 400) for (as they say) more f/stops of Dynamic Range.

    and any other recommended comparables relating to flat/vibrant colour footage?

    HLG isn't flat but it is very nice.

    Thank you,

    You are welcome.

    This is how VLog-L looks before and after.

    Just to get an idea.

    This is a C4K documentary shot on GH5 and edited on MC.

    Re: Panasonic GH5 & V-log

    George - many, many thanks.

    Couple of quickies (I am new, so please bear with me):

    1) What is the HEVC codec?
    2) Please explain more about "I don't need it as this little machine can shoot INTERNALLY 10bit 4:2:2 in HD, UHD and C4K".
    3) If I buy v-log for the GH5, do the appropriate luts come with it that run through Avid?
    4) Keeping this simple for me, are you recommending v-log or not? If not, what else? (My first job many years ago I trained as a photographic colour grader for portraiture, so whuile I cannot name my 'style', I do have a certain consistent look that I like, which in the main is natural-esque while a touch more vibrant, slighly preferring magenta hues over red, and avoiding the obvious warmth of yellows as they often tend towards greens, yet overall I do still aimfor a warm look.)

    1) What is the HEVC codec?

    H265 (newer than H264) with the same quality but less quantity.

    Media Composer can't read it yet. GH5 has a new Resolution with HEVC at 72 Mbits as I told you but it is 4:2:0 at 10 bit.

    2) Please explain more about "I don't need it as this little machine can shoot INTERNALLY 10bit 4:2:2 in HD, UHD and C4K".

    What do you need the Ninja recorder for?

    3) If I buy v-log for the GH5, do the appropriate luts come with it that run through Avid?

    The term LUT is a new fashion used by anyone. Media Composer supports 3D LUTs.

    You can download the official Panasonic LUT which personally I do not like.

    You can find thousand of those and all you will do is to forget what you knew.

    If you were a colorist you know better than anyone colors.

    As you will see at the simple tutorial I made you don't even need a LUT for VlogL.

    At a next one I will show how to use a LUT.

    4) Keeping this simple for me, are you recommending v-log or not? If not, what else? (My first job many years ago I trained as a photographic colour grader for portraiture, so whuile I cannot name my 'style', I do have a certain consistent look that I like, which in the main is natural-esque while a touch more vibrant, slighly preferring magenta hues over red, and avoiding the obvious warmth of yellows as they often tend towards greens, yet overall I do still aimfor a warm look.)

    In any case is very good to have VlogL to your Arsenal.

    VlogL needs MUCH attention from shooting to editing but as a colorist you will have no problem.

    I am pretty sure sooner or later you will create your own color style.

    To correct something I said earlier: even HLG (as VlogL) has 400 ISO as the lower setting.

    Re: Panasonic GH5 & V-log

    Hi George,

    Again, thank you.

    1) I take MC will catch up on this codec soon?

    - Can you elaborate more on 2) and 3) ?

    4) I still haven't fully a grasp on the idea of LUTs (Haven't needed to try and learn just yet).  One that interests me is the notion of "false colour"; is this some kind of exposure aid ?

    Re: Panasonic GH5 & V-log

    LUTs normally fall into 2 categories.

    The first and simplest is a Look applied to alter the characteristics of the shot. That could be in the luminance or the handling of colour. Normally this type is applied and thats it you now have modified content.

    The more common usage is to modify the content from the camera before its recorded to optimise the luminance dynamic range beyond the capabilities of the recording medium.

    Theres now magic involved in this so what happens is less important parts of the exposure are squeezed into a smaller bit range allowing the more important areas to be unaffected or even expanded and or the upper exposure limits to now be retained and hence the dynamic range is extended.

    However to shoot using a LUT that does this you often have to overexpose the shot slightly (or you risk not using the upper bit range at all)

    And of course the content seen without the LUT applied in the edit looks wrong. Often washed out and low contrast. Applying the LUT (or actually the reverse LUT) undoes those changes. 

    So often the offline editors will work with the LUT applied to make the images look sensible (but highlights maybe over exposed) The Colorist may well work with the content directly to decide how to manage that additional exposure range.

    More often than not LUTs are used without an understanding of what they offer and how to use that to improve the content.

    To add to what Pat said:

    There is also a LUT like, viewing aid in the camera, so you could see how it supposed to look like at the final edit.
