Tutorial: GoPro Video with a Lightroom Photographic Workflow

Like many others, I wanted to find the very best workflow for working with video footage from my GoPro Hero 3 Black. I've seen most people try shooting in Protune with RAW white balance and then try some sort of transcoding prior to colour grading and editing. Typical workflows involve transcoding with GoPro Studio (formerly Cineform Studio). I've also seen people experimenting with DSLR tools like 5DtoRGB with varying degrees of success. Before we get started, here's a video I created using this workflow - so you can decide whether it's going to be worth it for you to adopt my workflow - please remember to watch in 1080p high definition & full screen!

Why transcode at all?

The reasons you'd want to transcode before doing anything else? Firstly there's the video format of GoPro footage. Like many cameras it delivers its footage in MP4 format encoded with the H264 codec. That’s a highly compressed delivery format designed for the Internet age. It requires a lot of horsepower to decode it. When you're editing you don't want to be wasting your limited horsepower on decoding video, so most people want to use an editing format such as Apple ProRes 422, or indeed Cineform. I was spending a lot of time transcoding just so I could edit my footage... so much time that I began to wonder whether there might be another way, perhaps one better suited to me as a photographer.

What is Protune?

It's worth saying something at this point about Protune on the GoPro, because although it's been covered in many places by many people, it's still very much misunderstood. Firstly, Protune is NOT raw video. It's still H264 encoded MP4 video. But it's rather less pre-processed by the GoPro before it hits your memory card. Firstly there's no sharpening. Second, there's no contrast or colour correction so it looks flat and dull. Third, the GoPro raises the data rate used in the encoding process. This means one thing - that each frame suffers less loss of data as it's turned into video. That's less loss, not none. It's still not raw, but it's better than nothing, and since each frame is going to be on screen for at most 1/25th of a second (apart from that damned pause button), it's ok that it loses something. What you hope it's not going to lose is too much colour or contrast depth, so there's still plenty of data to process later on.

Colour Grading

The next step is some sort of colour grading process. This is where you try to impose a particular look in your video footage. If you have footage from multiple cameras, this is the stage at which you try to make it all look the same. With GoPro Protune footage it's where you take all that flat-look, high data-rate video and give it some colour & depth. Adobe's SpeedGrade is a great place to do this, allowing a wide range of creative options to videographers. But I'm a photographer, and I'm accustomed to the richness you can get from RAW images by processing them in Adobe Lightroom. So I wanted to incorporate some of that richness into my video workflow too. Lightroom handles video these days, doing a reasonable job of trimming and colour-adjusting footage. But I wanted more. So I elected to ignore Lightroom's video features and approach my video workflow as a photographer.

My Workflow Process

1. Extract the Frames

Fortunately in the Adobe CC suite I found most of what I needed. Firstly I needed to get still frames out of my video. Adobe Media Encoder is the way to do this. Give it a video from the GoPro, then choose a stills output format and go! My short flight video, shot at 60fps, yielded almost 5000 frames. You can output in JPG, but remember it's a lossy format, so your still images won't be without artefacts. It's better to use TIFFs, although they'll be bigger. At least they're as good as your video frames and not reduced quality, which is what you want if you're going to be processing them further which is the whole point of this exercise.

2. Edit the frames

So… you have your frames. Next import them into a Lightroom library. Select one, and start editing it to look how you want it to look. Remember this is stills editing so you get to use everything Lightroom has to offer. Graduated filters are great. So is its noise reduction and sharpening. You could also use Lightroom's lens profiles to correct for the GoPro's fisheye distortion and chromatic aberration. When one frame looks how you want it, try syncing the settings to all the others. If a section of frames don't look how you like them, make adjustments. Just don't try to edit every one of the thousands of frames individually!

3. Export the frames

Once you're done, you'll need to export the frames with their edits in place. Once again you could use JPG, but it's better to go lossless with TIFF. The whole reason we're doing this is for quality, after all.

4. Reassemble the frames into a video

Then you'll need to reassemble the frames into a video clip. The simplest way of doing this is using QuickTime Pro. The Pro edition is an inexpensive upgrade to QuickTime offered by Apple. The feature we're after is the Open Image Sequence option on the File menu. It'll take a while but eventually a video appears on screen which you can save as a movie. Congratulations, you now have a movie clip freed from the MP4 H264 format and suitable for editing, having been colour-graded photographically in Lightroom.

My Rig

I get asked a lot what hardware I'm using. So here it is. Afterwards I've laid out some of the rationale behind my choices. • Intel i7 4770K Haswell core CPU • 32Gb RAM (max) • 2 x Samsung 840 Pro 512Gb SSD • Loads of big SATA3 HDDs • Asus Sabertooth Z87 motherboard • NVidia GTX 770 GPU Hardware can make a big difference to your workflow, including whether or not a particular path is even viable at all. However I've seen people make silly uninformed hardware decisions that they've regretted. You shouldn't just blindly buy stuff hoping it'll make a big difference. The secret with hardware is, as with many things, science. Target your upgrades to your bottlenecks. That means using simple tools like task manager & resource monitors to work out where delays are occurring, thus identifying those bottlenecks. Then make an informed decision to purchase items which will alleviate specific bottlenecks. The slowest component by far is your spinning hard disk (HDD). Lots of people go on and on about defragmenting. But honestly, it's not going to make a lot of difference. You want stuff that's many times faster, not just tinkering around with milliseconds. So for the best speed, do all your work on an SSD, and archive onto cheap traditional electro-mechanical spinning hard disk drives (HDDs). Even the slowest SSD is 100s of times faster than the fastest HDD. SSDs are still several times more expensive than HDDs, but I recently purchased a Crucial 500Gb SSD for just £133 from eBuyer, making it a very affordable upgrade. Next in line is RAM. You can't really make RAM a whole lot faster, but you can often make it bigger. With RAM, size is everything. When you fill it up with running programs and their working data, your computer will start paging to disk. If that's an HDD then you're paging something very fast to something a hundred thousand times slower. So make it an SSD instead. But better still, fill all your memory slots to their maximum capacity so paging becomes less of a likelihood. But don't let all that memory go to waste. On a PC, use a 64 bit version of Windows with 64-bit versions of your tools. That way the PC will make use of all that RAM you've given it. Otherwise, your old 32-bit version of Windows will merely address the first 4Gb of RAM. If anyone has any other useful performance tips, please comment!

Commercial Photography at LaFarge Tarmac Concrete Plant, Shoreham Harbour

Commercial/public relations/press photography Lloyd Weedon of LaFarge Tarmac ShorehamAs a commercial photographer, I get asked to take photos of some very interesting things in some very interesting places. Commercial photography is like that, a very mixed bag. Some jobs are more interesting than others. This one was a press photography job which brought me to somewhere I've seen from afar for most of my life, but never up close. However that was about to change. LaFarge Tarmac's internal staff magazine was looking for some photos for a feature on a site supervisor at its site at Shoreham Harbour. The site supplies aggregates & ready mix concrete, and has a complex of huge conveyors. I've seen them before, and indeed photographed them before as a sculptural piece of industrial architecture in an industrial landscape shot. This was somewhat different: the noise, mud & dripping water along with the constant movement make the machines come alive at close quarters. They were to be as much the star of the show as the site supervisor Lloyd, who tried to look as natural as possible whilst being photographed doing various safety inspections and maintenance tasks. The photo I've featured here was of Lloyd standing next to a moving conveyor, taken whilst I was standing on a slim gantry suspended high above the site. And to think I was once scared of heights... though luckily travel photography helped me get over it years ago. If you have a requirement for commercial photography of any kind, be it corporate portraiture, press, food or public relations photography, please give me a call.

A Ditchling Church Wedding for Lou & Andy in photos

Lou and Andy had a heartwarming, intimate wedding in the beautiful St Margaret's Church in the historic East Sussex village of Ditchling. I really love photographing this sort of wedding, and in the same way Lou and Andy warmed to me the instant they met me, I felt the same about them. They were getting married around a month before I married my wife, so we even exchanged a few wedding ideas. Afterwards, Louise said "I really cannot speak highly enough of Jon and his photography. We weren’t going to have an official photographer at all for our wedding since neither of us are particularly comfortable in front of the camera. However, when I stumbled across Jon’s website and read about his more ‘natural’ approach to wedding photography, we thankfully reconsidered. Within moments of first meeting Jon we were not only bowled over by his stunning photos, but also warmed by what a thoroughly nice bloke he is! Jon understood exactly how we wanted the day captured and completely empathised with our reluctance to pose for a full-on photo shoot. On the day Jon was an absolute pleasure to have around. The guests all loved him and he managed to beautifully capture the essence of the day without us even noticing the shots being taken. Needless to say, I would highly recommend Jon to anyone wishing to have their special day captured on camera. Especially those who, like me, are usually filled with dread when asked to strike a pose for the camera!" and her friend Bonnie said "Totally didn't even notice there was a photographer! Like a photo-taking ninja!!" If you'd like a thoroughly nice photo-taking ninja to come and photograph your wedding, please read more about my wedding photography services and get in touch.

Business Portrait Photography for JFDI

My old friends and colleagues over at JFDI needed some new photos for their LinkedIn profiles, and a new project called The SharePoint Doctors - so of course they came to me. Business portrait photography is a bit of a psychological business... it's one thing to get someone relaxed enough to take a good photo of them, but with business portrait photography it's all about conveying a positive message about the person to whoever sees the photo. Communicating what you need someone to see in just a still photo is a difficult and onerous task, and not to be taken lightly. But judging by the number of my photos I see chosen on LinkedIn as my clients' profile photos, most people seem to like what I've done for them. It's different again photographing people you know... but a real laugh... there was barely a dry eye in the house due to the almost constant messing about. But the result was some very relaxed portrait photos of a couple of chaps who are great at what they do for work, but really don't like having their photo taken - which of course is one of my specialities! If you're not keen on having your photo taken, give me a call and I'll do the same for you.

Baby Bertie’s Woodland Photo Shoot

It's lovely doing photography of babies - their parents love it, and if the baby is a cheerful, ebullient soul like Bertie here then the photos are bound to come out great because he was just soooooooo amenable! He toddled off around the woods, fell down repeatedly in the late Autumn leaves, totally undeterred... and we followed him around in the mist, constantly aware of the woodland magic of falling leaves and incredible Autumnal colours. His mum dressed him in lots of different outfits and we took lots of photos... and here are just a few of the results. Baby portrait photography is available in my Brighton studio or on location anywhere in Sussex and beyond. If you'd like your baby's personality captured in beautiful photos, please get in touch.
