APV Now Captures In 4K UHD!

Hello all! Great news comes from APV in the form of the latest revolution in cinematography; capturing and delivering video and media content in 4K (3840x2160p) or Ultra High Definition using the Sony A7S camera and Atomos Shogun recorder.

Seeing the release of both the Sony A7S and Atomos Shogun at industry events, I was so keen to get my hands on this kit. Unlike DSLR's the A7S is mirrorless which means it's body is around 1/3 the size of the Canon 5D mkIII, it has incredible light sensitivity, the features to film in both slow-motion and using the S-Log gamma curve make it an ideal production camera in a tiny body.

I first saw the Shogun outside of an expo at the Shadows and Light workshop, a friend was showing me some footage he shot the evening before on the setup in 4K. He showed me the captured footage, and then applied the LUT in the Shogun to show what the result would be after grading.. I was blown away. Both as a monitor and a recorder, the Shogun excels at capturing HD and 4K video and audio with in-built monitors such as waveform and vectorscope, peaking, zebras, as well as recording in a range of formats at a much higher bit-rate than in camera recording - 220Mbit/s HD and 440Mbit/s 4K (I think) which is perfect for grading and video-focused productions to filmmaking.

I invested into Canon EF equipment a couple of years back as the 5D mkIII was to best option for large sensor filming, so instead of spending out on native Sony E mount lenses I purchased both the Metabones EF-E mount mk IV and the Commlite EF-E mount to use my current lenses.

Also knowing that the batteries for the A7S (FW-50) are much smaller in capacity than the LP-E6 Canon batteries, I ordered another 4 Sony's with the camera and two from Amazon with another charger (EX-Pro). Inevitably, all of the accessories came before the camera did.. So I eagerly charged and labelled up the kit and get it ready for the camera to arrive!

The camera came last week and not having any new toys for a while I was keen to play around and check out the cameras features straight away! Glen came over as the camera arrived, so he became my willing subject. I hooked up the Tamron 24-70 to the Metabones which worked fine and shot some handheld video, as the lenses vibration control was active. I also have an eyecup for the little viewfinder for another point of contact, to reduce the shake if I need to hand-hold for some shots.

As I was waiting for numerous deliveries to arrive (including the Shogun), I was housebound for a while so I made do with the plants in the garden and my cat for things to film. Here's some of the first footage captured -

A mix of footage shot for the first time on the Sony A7S, probably in No Picture Profile. Really love the image with the lenses that I have, very organic with fantastic light sensitivity. It was also impressive hooking up the Atomos Shogun to the 5D mk III for 1080p in ProRes HQ, which gives much more latitude for colour grading and post work because of the much higher bit rate.

The best friend has bought a swanky new Audi, so he took me for a spin! I was still getting used to the photo mode and controls, it was past 8pm with the sun only just set so the ISO was wacked up reasonably high.

Because the cable for connecting the A7S to the Shogun hadn't arrived yet (from Atomos) I went searching around Epsom with no avail for a micro HDMI to HDMI cable. I ordered one off Amazon for evening delivery, which came while I took the photos of Sams new car!

I was overly happy with the recorded images that I captured in the mean time with the Shogun hooked up to the 5D mk III. I decided to record them in ProRes HQ to see how far I could push the footage in colour correction, post and grading. It worked fantastically, so much in fact that I'm deeply considering teaming the 5D mk III with another Atomos recorder for the same reasons as above.

I finally got my hands on a micro HDMI cable to road test the 4K HDMI output from the A7S to the Shogun, and just as I began to film, Alfie the cat decided he wanted to join in! I don't remember the picture profile, but it was shot with a pretty wide aperture on the Tamron 24-70. I also tried out the down-ressing method that I'll be using for 4K filming but delivering in HD, so I edited the 4K sequence twice, one in native 4K resolution and the other in a 1080p sequence with some clips scaled down or cropped. NOTE - please change the resolution to the highest possible for the best results!

4K still from the Shogun recorder, shot in 4K ProRes HQ

Let me know what you think!

NOTE - Change resolution to 2160!!!

A short first test filming in 3820x2160 UHD-4K resolution in ProRes HQ on the Atomos Shogun, with the Sony A7S camera. No correction/sharpening/grading in camera or post. Exported in H.264 with a target bitrate of 100Mbits, hoping it holds! I tried to shoot some orchids, but my cat Alfie saw what was going on and wanted to join in!

4K version on Vimeo, remember Vimeo does not have 4K playback yet so this has been down-ressed by Vimeo. Please watch the Youtube video above for the 4K version.

As a comparison, this is the down-res version of the 'Creatives and their cats' video originally shot in 3840x2160 4K-UHD using the Atomos Shogun and Sony A7S. View the original here - This version has been scaled down in Premiere by 50%, with some re-framing in a 1080p sequence, with 4K footage. No correction, sharpening, grading in camera or post. Originally shot in ProRes HQ. I tried to shoot some orchids, but my cat Alfie saw what was going on and wanted to join in! The cropping and re-framing of 4K footage for 1080p HD delivery is a brilliant feature to have, meaning high quality footage can be future-proofed and still delivered in great HD resolution.

I also shot some Picture Profile tests to compare the colours, DR, contrast and noise, this is to come later!

New Rokinon/Samyang 12mm lens!

Rokinon/Samyang have been pioneering high quality photography and VDSLR lenses for a number of years now, and with the introduction of their Cine lens range they are a must have for intermediate kit choice for a number of reasons:

• Incredible build quality results in top images; compared with Canon L series, this glass holds up nicely.
• Price; cheap enough to get a whole kit for the price of one L series lens.
• Manual control; much better for video, allowing subtle aperture changes and precise control.
• Small size; I've got 3 and they all come out with me. They aren't large lenses to carry or use on camera.

Rokinon announce another cine lens to their line up; the 12mm F/2.8 (digital photo) or T/3.1 in the VDSLR model. An ultra-wide fisheye, perfect for large landscapes, extreme perspectives, fast sports and music vids.

Personally, if I was to purchase this new lens I would go for the 12mm F/2.8 digital photo model for use on crop sensor cameras for an effective ~18mm focal length.

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.
