Testing out the new Panasonic GH4

There have been three new arrivals at JHWF HQ this morning, three beautiful Panasonic Lumix GH4's!

I've had the opportunity to check out the GH4 at Park Cameras a few months ago, so today was a great opportunity to get proper hands on with the new camera system!

We didn't have time to do a proper test, so I took a few shots to demo the 4K at 100Mbps AND the 1080p 50fps features that are currently exporting in Premiere now.

Out of the box, holding the camera using the viewfinder seems so natural for video, as well as the OLED live screen which produces a clear as day image with overlays.

Using the stock lens 14-140mm F/3.5-5.6 (equivalent to 28-280) the image was sharp, with very minor chromatic aberration at 140mm. I am used to a 'full frame' look, but remembering that the Arri Alexa has a similar sensor size the the GH4, what lacks in the stock lens can be gained using the wide range of primes available for M4/3 mount.

The OIS stabilization was actually incredible. This being hand-held, the shots were very shaky at the long end, but the OIS did a brilliant job of stabilizing the image.

Another fab feature is the variance in recording formats, whether you are shooting on a green screen, or footage that is live streamed, the data rates are manageable and not small enough for heavy compression meaning grading the footage should be a breeze. (In my test video coming very soon I have NOT graded any footage).

Things to make note of: If you are going to purchase a GH4 but currently shoot with Canon EF lenses, do not worry. Lensadaptors have developed a M4/3 to EF adapter, there is also one from Blackmagic to Nikon G mount, and rumors are circulating that Metabones are working on a direct M4/3 to EF lens as we speak!

Well, there will be LOTS and LOTS more to come as I continue to play and test out the GH4 so watch this space!

Meet the Panasonic GH4

We've been waiting a few months for more info on the Panasonic GH4. It briefly appeared at BVE, and only 8 were shown at The Photography Show. Due to Panasonic UK announcing the launch of the GH4 early from the trade show and professional demand, more people are asking the whats and hows of the GH4's video capabilities; in regards to 4K. It is the first consumer DSLR to offer 4K, which is a fantastic leap forward into the future of video production that will inevitably get bigger (Moore's law). We have seen recent demonstrations of Super Hi-Vision (8K) at the London Olympic games from collaboration between NHK and The BBC, but for the first time have we seen 4K possibilities coming home with us. It is now in reach.

Today, John from JHWF, his son Sam and myself headed down to Park Cameras in Burgess Hill for the Panasonic GH4 demo. Eager to try out the camera, and by that I mean actually get your hands on it and play with it, checking out the range of functions and lenses that can be used (something not so easy at trade shows), it was the perfect opportunity to get a glimpse into the reachable future for us as producers. Even more so for John, as he as already invested!

Adam from Panasonic was on hand to answer our many questions, and to demonstrate the innovative features the camera has to offer, which include continuous auto-focus in video mode, as well as how the 4K is achieved from an MFT sensor, and many more..

First of all, the body is tiny. If you compare the body to that of my Canon 5DmkIII it could easily be half the size; which for run and gun videographers, and to keep discreet is a perfect solution. Not only that, but like the Sony A7, you have a large pixel count/density sensor so regardless of the body size the image result will be incredible.

The sensor offers the two 4K resolution standards; cinema 4K at 4096 x 2160 and UHD 4K at 3840 x 2160 up to 30fps at either 200Mbps (All-intra compression) or at 100Mbps (IPB compression), which is much better in terms of .mov image quality in comparison to the 5D mkIII max 90Mbits at All-Intra compression. Essentially this means that your image is being recorded in a better quality format, giving richer colours, wider dynamic range and more latitude for grading in post. The HD video format is top notch, offering up to 200Mbps in MP4 format, much better than nearly all DSLR's on the market today.

Due to the MFT sensor, the focal length of the lenses you mount are doubled for the equivalent. For example a 12-35mm F/2.8 is equivalent to  24-70MM f/2.8 ON A Micro Four Thirds sensor. This means that suddenly the size of the lenses you use get greatly reduced, meaning a smaller kit bag and less back ache at the end of the day.

A run and gun kit using the GH4 could include the 12-35mm as mentioned above, and the 14-140mm F/3.5-5.6 is enough to cover your indoor and outdoor shots, and can fit in a small shoulder bag. What more could you ask for?

The dual OLED screens replicate the live sensor beautifully, with such clarity too. Now a live view finder has been implemented into the view finder, you get an incredible 10,000:1 contrast ratio which is extremely high speed, unlike LCD which refresh rate is much slower. No need for a Z-finder anymore! Oh by the way it is touch screen too, and you can focus and take a photo by tapping the area of the screen you would like to focus on!

Another incredible feature was the built in Wi-Fi which can be used to control most of the cameras functions INCLUDING touch sensitive focusing and recording (in 4K) via your Apple of Android device! So, leave your camera set up with the Wi-Fi connected to your device and set up your shot from elsewhere! In the right situation, this feature could be killer, much like the GoPro's wi-fi function for those awkward and obscure shots!

More professional video features include; zebra bars for setting exposure, center marker for image composition, colour bars and 1KHz tone, synchro scan which is useful for suppressing TV and fluorescent light flicker and a Cinelike gamma curves which can be applied. This would come in handy for productions where heavy grading and LUT's can be applied.

There is also the YAGH interface, which was not at the demo, but its functionality is to provide a DC-12V power input to the camera and interface, which allows 4:2:2/10 bit recording with XLR inputs, timecode, VU meters, which turns the camera from a pro-videography/cine camera to a full system camera for broadcasting. Adam showed us some setups on his phone from recent Hollywood productions using the GH3.

As you may know, I purchased my 5D mkIII in December, for videography/cinematography. To me, I don't know if I should feel pissed off that I should have waited for the GH4 to be released so I can future-proof my productions, or whether I should jump in and get another A camera right there and then. But then I thought, I have an incredible camera system right here already, and just because this (yes rather amazing) new resolution has become available, doesn't mean my potential clients will want it. At the moment the current structure and system for broadcasting 4K in the mainstream media of television is non-existent, until the big change happens which means either updating current HD systems to cope with the greater requirements of 4K, or a completely new 4K network is created, the only channel for viewing will be the internet, or cinema. So, if your deliverables are all for YouTube, then go for it, you have a way to get your work out there in its native resolution already. Otherwise, be prepared to down-scale to 1080 HD for normal playback. This may have fantastic results for you, and keeps the incredible clarity, colour richness and the 'wow' factor that 4K is now being renown for.

If you are a current Canon/Nikon or other brand shooter, then the answer to your question is not "You will need to buy new lenses for this camera". A few manufacturers haave designed and produced many workarounds to lens to mount converters; famously Metabones, but also LensAdaptor are worth checking out if you currently shoot with non-MFT lenses. These adapters fit onto the body and lens and effectively allow the lens to be used with a different lens mount.

To conclude, if I had the money I would happily invest in the Panasonic GH4 and not only for the 4K. The high data rates even for 1080p HD are high enough to be broadcasted which opens up what I can deliver for my clients, the kit is smaller so I get less back ache, the Depth From Defocus system allows continuous auto-focus during video, up to 96fps slow motion recording in 1080p HD, Wi-Fi control. I'd be really interested in testing this camera out in a 'Great Camera Shootout' review, so clear up the rest of the questions I have about not only capturing video in 4K, but also to see how the MFT 16Mp sensor holds up against the Canon 5D mk III which with Magic Lantern can record RAW.. We shall see, only the future will tell!

Please bear in mind that I have never captured footage in 4K, or worked with a 4K camera, footage or system. So what knowledge I am basing this on is my university dissertation in implementing 4K programming into the current UK broadcasting industry, copious research into 4K cameras, technology and productions, attending IBC and many other trade shows to understand the up-to-date technology available.

Update from Adam!

It has been a very busy couple of weeks since BVE, which by the way was great this year. I was over the moon to see the new finalized range of Manfrotto LED Spectra light panels which I got to test out a couple of years ago. Seeing products develop over a long period of time is interesting, even more so when your opinion is considered in how the final product should perform. Manfrotto also had their re-designed SIMPLA rig to demo, a much lighter and more ergonomic model I must say which is compatible with 15mm rig accessories like their matte box and electronic remote control.

As well as that, Manfrotto have also joined forces with Schneider Kreuznach optics (page in German), who have a new range of cinema lenses, specifically designed with ease of use in mind. All of the lenses from 24mm to 135mm have the same filter size, length and focus rotation to make filming with a range of the lenses effortless, simply change the lens and your peripherals stay in position. The optics of the lenses blew me away. Even in the well lit Excel, the background bokeh was stunning, soft yet so crisp. I cannot wait to get my hands on them. I think the combination of the new Manfrotto 055 tripod, the SIMPLA rig and Schneider glass will be a killer cine kit, delivering incredible visuals, making your shoot run smoothly, and at a low cost. Give it a year and this will be the go to package for production rentals, and part of every kit bag.

In other news, I've been working with EEBC on a couple of projects; a short video on recycling and another about a Wellbeing centre for those suffering with dementia and their carers. Both projects have messages that are close to me, so I've been working hard to blow my clients expectations out of the water. For the recycling video, I'm combining video with animation to show why recycling food and material waste is ever more important today; generating renewable electricity and resources. The Wellbeing centre video will be live action video, featuring the range of activities available to those in the community as well as the vast benefits to carers and visitors to the centre.

So, busy busy at the moment. I'm also meeting some designers from the fashion label ACF (Art Comes First) next week about another video featuring the design process here in London. Very exciting, I've been patiently waiting for an art-collaboration project to come along, it's what I started the business for!

I've had no #videoquestions for a while, so remember to keep them coming to @Plowman91!

Remember, inspiration is everywhere so take your camera with you!

EDIT!!!! Just remembered to include this, I spoke to an un-named informant about the new Samyang/Rokinon VDSLR cine lenses and whether any new models are going to be released. Our brief chat resulted in confirming rumours of a 50mm and 135mm cine lenses coming very soon! I think it's exactly what the lens range needs, and I will certainly be investing in the 135mm if it is at T/2.2, or pushing it at T/1.8 would be a dream come true. So hear my thoughts Samyang/Rokinon!

Panasonic announces the GH4 - 4K DSLM movies!

Check out the specs of the new model here - http://www.panasonic.com/uk/consumer/cameras-camcorders/lumix-g-compact-system-cameras-dslm/dmc-gh4heb.html Photo from Panasonic website.

Looks very impressive, but as usual a highly compressed Youtube product demo doesn't do it justice.. For all those interested in having the extra resolution to work with, as well as a newly developed MOS sensor then this camera may be your first port of call instead of the previously available Canon 1D-C.

It will be interesting to see how the industry responds to this new release,  as many more productions working in a higher res to downscale later.

What interests me about it, is not only being able to capture footage in 4K/2K, but also 1080p HD slow motion at 50 and 60fps. My main drawback at the moment is using the 5D mark III setting of 720p for 50fps, which is fixed at that resolution. The higher bit-rate is very appealing too, despite recording in MOV file formats 100Mbps is a great advantage over the highly compressed Canon DSLR movie output files.

Lots of points to consider, and no mention of a price yet.. Hopefully Panasonic will be at BVE so I can get my hands on this bad boy!

Trials of editing audio

For those that who have ever been at a gig and lunged their phone or camera in the air to try and capture some of the performance will know that the only sound recorded by the terrible on board mic will be CCCCCCCCRRRRRRRRRRRRRRRGGGGGHHHHHHHHHHHHHHHHHHHHHHHHHHHHH, or just distorted noise. Luckily, I record with external microphones when I film performances, usually because there isn't another option. Bands these days can't afford to hire a PA system with a multi channel mixer w/EQ, especially for one off performances, so it is common to see, so always be prepared!

There will always, however be background noise and hissing that will need to be removed from the recorded audio, I'm using Adobe Audition at the moment to eradicate that from the John Sinclair performance, as its functions for calculating and removing frequencies from audio tracks is phenomenal.

In the multi-camera edit suite!
