etidona Posted March 12, 2014 Share Posted March 12, 2014 We're only arguing here. Personally I don't need a huge 6x6cm sensor. A 17,3x17,3mm would suffice for now (call it Micro 4/4). Maybe in the future a 24x24 (call it APS2) and a 36x36 (fullsquare). nice names uh? :D Quote Link to comment Share on other sites More sharing options...
Michael1 Posted March 12, 2014 Share Posted March 12, 2014 A few pre-production videos are starting to surface. My initial impressions are the GH4 doesn't look as cinematic as the BMPC, and the flesh tone colors look slightly unnatural. Michael Quote Link to comment Share on other sites More sharing options...

Michael That's because the pre-production models are being given to people that have no idea about what they are doing, most likely photographers with no real interest in video. Also, most (if not all) of these videos are being shot with standard colour profiles etc. We need someone like Andrew who would test out the Cinelike profiles the GH4 has, then graded properly with an upload on Vimeo so we can download a clean original file. Only then can me make a call on how good the GH4 really is. Quote Link to comment Share on other sites More sharing options...

Michael I would never base a purchasing decision from footage you have seen online. 90% of the quality is down to the operator and how they have edited it. Try first, then you will know for sure. Whenever that will be. Quote Link to comment Share on other sites More sharing options...
joe1946 Posted March 12, 2014 Share Posted March 12, 2014 i'm not aware of media technology. is this type of card faster than a sanny extreme pro 95mb/s? The Sandisk Extreme Pro 95MB/s card is a class 10 card meaning minimum 10MB/s compared to 30MB/s minimum for the speed class 3 cards. https://www.sdcard.org/consumers/speed/speed_class/ http://www.sandisk.com/products/memory-cards/sd/ Quote Link to comment Share on other sites More sharing options...
ImageMaker Posted March 18, 2014 Share Posted March 18, 2014 yes, its like the GH3 at 1080p. when you switch to 4K however the crop is even higher. i dont have the exact numbers, 2.25 crop i believe? are thre aready comparions between GH3 and GH4 @ 1080p? maybe even stills in comparison to GH3 or EM1? i think that the GH4 is a great camera, with the official price tag it sounds even better, but the handheld shooting style is still very popular and i need my next camera to have IBIS. switching from my 25mm 1.4 to the 14-140mm just for OIS, just isnt acceptable anymore. i would have rather seen a GH4 with sharper 1080p compared to GH3, IBIS and no 4K option, than what the GH4 offers right now. sure 4k is nice to have and Andrew always says that you can always downsample it to 1080p obviously, but that happens at the price of a smaller sensor. sure its only a very small difference to m43, but we have to draw the line somewhere. going from fullframe to apsc to M43 multiaspect to M43 to cropped M43 doesnt cut it anymore for me. when i buy a new generation of a camera i need it to be better or at least the same in ALL aspects. cropping m43 even more is definately a step back that im not willing to take. however i can understand anybody who ll buy this camera in a heartbeat :) You hit the nail on the head.. Everyone is clamoring about the ability to shoot 4k but no one is paying attention to the underlying issue that the GH4 still shoots a poor de-bayered image that(much like pretty much anything else currently available under 12k) lacks detail. Shooting RAW OR 4k is not a feasible solution for MANY projects. I recently shot almost a Terabyte of 1080 footage for over the span of 3 days for a documentary(think about how that would limit or impact what you shoot, how you shoot, how often you would need to backup, etc). I see many positives to what the GH4 can provide(cropping 4k is super useful, pulling stills, etc), but I also see many negatives(including the headaches and limitations of the dslr footprint). I too would rather have seen a dslr format that could shoot a better QUALITY(non-debayered image a'la F3, c300, 1dc) 1080 image with increased bit depth, dynamic range, and the ability to over crank rather then get 4k and an externally powered box that enables sound and hd-sdi. Aside from it appearing to be an awesome camera with some great features, Right now I can't help but see the 4k feature in particular as being more of a "gimmick" for aspiring filmmakers to waste money on rather then becoming a serious tool for the arsenal.

ImageMaker Posted March 18, 2014 Share Posted March 18, 2014 It's not really comparable to the C100, it's much better than that. Not to hijack the thread, but that is an erroneous statement. A better way of putting it would be, the gh4 does a lot of things better then the c100, however it also DOESN'T do a lot of things better than the c100. For instance, Light an interview properly, setup both cameras and the end result will give the nod to the c100. Better yet, set the gh4 to 4k mode for that interview and transcode the full image to 1080(because that is what you will need to match the detail level of the non de-bayered canon) and after changing the memory card about 10 times and going through the headaches of backing up, transferring, transcoding that kind of data, I would still say the C100 would result in a more pleasing final image. Just so folks know, I'm not talking about data rates, dynamic range or actual resolution when I refer to image detail. Unlike what most other cameras are doing, Canon's cinema line does not de-bayer the raw image stream the same way most dslr, gh3, gh4, 5d, fs700, bmcc, bmpc does. The c100 also gets a nod when examining the efficiency overall (built in xlr, neutral density, battery life, s35 sensor) and let's not forget some pretty spiffy low light performance :) For a portable 4k aquisition tool, and cost, huge thumbs up for the GH4! For interviews, documentary work, events, weddings, large volume broll shooting. Big thumbs down. Not that it couldn't work for those demographics, but I see the c100 as an efficient tool that really does make life a lot easier for a lot of filmmakers. 2 different tools meant for different things I guess Zach Ashcraft 1 Quote Link to comment Share on other sites More sharing options...

While it has two more systems that has came after it and that are overpriced too. 5k for a system that doesn't even shoot 60fps. No Thanks.

The C100 only records 24Mbps AVCHD internally too! Such a crappy codec for 5K... what a joke. nahua 1 Quote Link to comment Share on other sites More sharing options...

I completely agree with your thoughts except for the overpriced part:) I don't own a c100 nor do I intend too, all I was trying to say was that what the camera does, it does VERY well. That "crappy" codec is 10x better and more manageable then any camera under 12k. A BMC for example. The initial investment is nowhere near 2k or even 3k. Some blog did a minimum cost assessment and it landed you somewhere in the 5-6k range to begin shooting. Keeping in mind, even with that amount, you still wouldn't have all the necessities OR efficiency that a camera like the c100 would provide. My underlying message was, your paying for features. Each of them comes at a cost. As filmmakers we should analyze which features we NEED, and determine what we are able to afford(ND filters, XLR, global shutter, 4k, battery life, low light performance, overcranking, codec options, ergonomics, build quality). Given the type of work I do, I could never invest in a camera that doesn't have the ability to shoot more than 24fps, but that doesn't mean I neglect the value it has for a potentially huge market. A lot of folks overlook the smaller subtleties that some of these cameras provide. If you have MFT lenses the gh4 really is a no brain'er.

Administrators Andrew Reid Posted March 19, 2014 Author Administrators Share Posted March 19, 2014 If you were paying for features then you would have a better spec than the C100 for your $5k. You are paying for the fact the C100 is perfectly suited to commercial work. The people it is for can all afford it and justify the investment. There's no point being upset about that either. We have some nice options now for cheaper. Let's not pretend we are paying $5000 for a built in ND filter though. dafreaking 1 Quote Link to comment Share on other sites More sharing options...
dafreaking Posted March 19, 2014 Share Posted March 19, 2014 HAHA...Andrew, that was awesome. I think, at least in theory that the 4K->1080p of the GH4 will definitely be as good as the 1080p of the C100 (detail wise) I don't agree that the GH4 is better than the C100 in everything. They both have their strengths and weaknesses. Pound for pound though the GH4 wins hands down as far as value of money is concerned. Quote Link to comment Share on other sites More sharing options...

Mozim Posted March 19, 2014 Share Posted March 19, 2014 Just a quick questions about the available frame rates on the GH4 vs the GH3... I bought the GH3 in Europe (PAL) so it gives me the option to record in 24p, 25p or 50p. Since I shoot a lot of slow motion, I set up the project as a 25p project and record in 50p so that I can easily achieve a 2x Slow motion. The GH4 is able to record up to 96 frames per second. Will this be different in PAL regions? 96fps would be a 4x slow motion if it's a 24p project but a 3.86x slow motion if the project is set up in 25p. This won't work. So far all I've read is the GH4 is capable of recording up to 96fps but not 100fps in PAL regions. Let's say I want to record slow motion stuff with the GH4 as my A-cam and the GH3 as my B-Cam. I set the GH4 to 96fps - this transforms well to a 4x Slow Mo in a 24p project but doesn't work with a 25p project. At the same time I set up the GH3 to 50fps - this transforms well to a 2x Slow Mo in a 25p project but doesn't work with a 24p project. Is there any workaround for this issue?

Guest Ebrahim Saadawi Posted March 19, 2014 Share Posted March 19, 2014 Not to hijack the thread, but that is an erroneous statement. Yes it's indeed a ridiculous statement but let's not forget what this website is all about, it's made for the low-budget independent filmmaker. So it's hard to blame Andrew for getting overexcited over something as groundbreaking as the GH4, it deserves overexcitement! Great times ahead Quote Link to comment Share on other sites More sharing options...
animan Posted March 19, 2014 Share Posted March 19, 2014 This won't work. It will work fine! 1 frame of 96fps will still equal 1 frame in your 25fps project giving you a speed thats 3.86x slower than the original.. (if thats what youre trying to do) The clip just needs to be conformed to your sequence framerate.. Mozim 1 Quote Link to comment Share on other sites More sharing options...

Mozim Posted March 19, 2014 Share Posted March 19, 2014 Oh well... should have thought about this! Thanks guys! Another questions regarding the 96fps mode: As far as I know the GH4 will record Audio only up to 60fps but not when overcranking the framerate. What if I use an external microphone and plug it straight into the camera? Still no sound, right? I'm assuming that I need an external microphone + external recorder if I wanted to have sound that fits the footage. Is my assumption correct?

Pascal Garnier Posted March 19, 2014 Share Posted March 19, 2014 The GH4 is available for preorder in the Benelux (Belgium & Netherlands). It's 1499 EUR for body only. etidona 1 Quote Link to comment Share on other sites More sharing options...
etidona Posted March 19, 2014 Share Posted March 19, 2014 http://vimeo.com/m/89515795 Two great news here: 1) the micro hdmi in camera outputs live 4k 10 bit 422, not just 1080p downsampled; 2)low light is improved by at least 1/3 stop over the gh3. 0db is about 800 iso.
