OK, a provocative title for my first post of the year.
It was incomplete and should have said…I use ACES because I don’t trust post guys I don’t know. Just like I don’t trust gaffers, operators, grips, AC’s who I don’t know.
I’ve been experimenting a lot over the last few weeks/months with generating LUT’s that are meant to help the shoot, not to dominate post or impose a “look” onto the final film but to give a level of control and predictability to images onset.
The thing is that “technical LUT’s” do a great job in the hands of people I know and trust but more and more we are having to work with people and workflows that we don’t know and trust and when things go wrong it’s inevitably the fault of the person not in the room.
This is where ACES comes in to play, it gives us a fixed, international , independent reference. Just take the rushes and apply the Image Transform (IDT) and the Output Transform (ODT) and we can see what we shot without any outside help or interference. If with a standard IDT and ODT the image looks OK then the rushes are OK and anything wrong is further down the chain.
That’s it, well for the Cinematographer anyway, there are other advantages for producers but this is a cinematography rant!
Now the problem with this is that we don’t have an ACES onset workflow established, Oh there are all kinds of ways that with DIT’s and shedloads of money we can do anything but I want something very very simple.
What we need are very simple LUT’s to use onset (via LUT boxes or wireless links that will accept LUT’s or via monitors that accept LUT’s) that will show us on a standard 709 onset monitor what the image will look like after going through the ACES post pipeline.
Thanks to Prelight from Filmlight this is now easy to do. I’ve generated LUT’s for Alexa, Canon, Panasonic & Sony cameras that integrate the ACES pipeline and can be used during a shoot in a very simple way. I’ve also generated for Alexa and Canon LUT’s that incorporate the ACES pipeline with a reduction in contrast to 0.85 because that’s how I like to see my rushes!
I’ve generated these LUT’s from both captured footage and live camera input. In the latter case it’s possible to add a “look” to the output as well.
I’m testing these with the NSC at the moment and we’ll be going live with all of this on the 24th of January and after that I may well post some of these LUT’s to the CML website. That is after they have been tested and torn apart by a lot of Cinematographers and DIT’s!!
Wow! just Wow!
I went to see Star Wars the Last Jedi yesterday at the Dolby Cinema in Hilversum and even if the film had been complete crap, it wasn’t, I’d have been blown away anyway.
This is what going to movies should be. A totally black theatre, no extraneous light of any kind, brilliant sound, totally brilliant images from a dual laser projection system.
If more movie theatres were like this attendances would be rocketing up. I normally go to the Imax in Den Haag to get the best possible viewing experience. The Den Haag Imax is a 20 minute tram trip right to the door of the theatre from home and the Vue Dolby Cinema in Hilversum is a tram and 3 trains away taking around an hour and three quarters. It’s worth the journey.
What’s the film like, actually it’s pretty good. You just have to ignore the obviously cute marketing characters and if you can do that then it’s by far the best Star Wars film since the original 3.
It captures the excitement and thrill of the original, how much of that was the overall experience is another matter 🙂
The force is with Dolby!
Even better being the Netherlands, instead of the audience having huge containers of sugary soda and popcorn the guys next to me had beers, bought in the main theatre concession area. I love it!
One of the joys of IBC and shows like it is eavesdropping on conversations by accident.
This year I heard a lot of people whingeing about kit, about how it didn’t give them the look they wanted, about how cameras disappointed them or software didn’t miraculously make their images great. Lighting hadn’t given them the look they wanted or camera movement, track, crane, drone, whatever, hadn’t done what they wanted.
I wanted to scream at them “learn your fucking job!”
It’s so easy to blame kit but the reality is that it’s all, and I mean ALL, pretty bloody good. Oh there are some tools that have issues but they’re not major image killing issues. There’s kit I don’t like the feel of and kit I don’t like the marketing of but thats different. I may not like that kit but I can’t deny that it does its job pretty well.
So why are people having problems getting the images they want?
They aren’t learning their job! They expect it all to just happen without having to put the time in to learn how to do it properly.
It takes time to learn to make great motion picture images, it takes time to learn about lighting, it takes time to learn about lenses, it takes time to learn about post, it takes time to learn the language of images
There is no Google translate for image making. You have to do it the hard way.
10,000 hours to become competent, not good or great, just competent.
Learn the job and stop complaining about kit, it’s you not the kit that produces the bad images.
This is just a plain out and out rant.
I’m finding more and more that I have to wait until night to be able to even try and watch some series. They are shot so dark that unless the ambient light is lower that it would be in a grading suite the whole thing turns into a radio show.
I think that there are a couple of issues at play here, first people, and that’s DP’s as well as directors, not understanding that an image doesn’t actually have to be dark to convey a feeling of darkness. In fact judicious use of bright area makes other parts look darker.
The other issue is highlights that are too bright, or areas of a shot that are too bright and that not only make dark areas look darker but also draw your attention away from the main interest of the scene.
I think, and I’m stressing that this is a personal opinion, that there is a huge amount of outright incompetence out there at the moment. People who really don’t understand how to use images to tell a story. People who should not be in charge of a camera.
Yes I do have a home with white walls and light grey floors and white seating and lots of windows but even at night with curtains drawn the image is too dark to see WTF is happening on screen.
Once we get HDR I’m going to have to paint the walls black change the floor and the furnishings, black the windows out totally and wear a burka to make sure that no light kicks back off my white face!
Guys, use a domestic set to check your grading and turn the f’ing lights up when you do, go out and watch it on a TV not a monitor in reception.
Ah, that feels better!
Oh and finally, I do have all the kit to set my screens up properly but I find more and more that I can’t use the “correct” setting on my home TV, I have to use a mode like Vivid! to see anything.
Get a grip!
I can’t stay quiet anymore, I have to scream!
I’m a member of a number of colour grading groups on the net and they vary from the great, LGG, to the unbelievably bad.
I made a comment a long long time ago that the way to tell who was a dailies colorist was to look for the white stick and the dog.
It seems that now everyone is a colorist and most of the so-called colorists are either color blind, partially sighted or completely blind.
I see examples posted online asking for comments, I have refrained so far.
My only comment would be “go and find an optician!”
Guys, you need to start with a good image. If after loading your work into your software of choice ( usually Resolve) set the workflow to ACES and use the relevant IDT & ODT. If after this your work doesn’t look pretty good you have fucked up the shoot! go and start again.
Great grading has to start with material the colourist can work with, yes a really good colourist can rescue crap work but there are limits.
If you give them good work to start with…
Please notice I am saying that you should give your work to a good colorist, not that you should do it yourself.
If, for whatever reason, you end up doing it yourself then shoot it right and don’t do a lot in grading.
It seems that everyone using grading systems for the first time finds the 11 setting before anything else!
I am so fed up with seeing oversaturated images with crap skin tones and weird contrast. Learn to do it right first. Don’t use the “I am an artist” excuse to cover up bad work.
Digital Cinema Cameras Full resolution EXR files
These are links to ZIP folders of one EXR frame per exposure +/- 4 stops
The EXR’s were generated by the manufacturers own software, with the exception of the Varicam which was done in Resolve as they don’t have their own software.
They are VERY large files. Most are in ACEScc space, if not it’s because the manufacturers didn’t specify anything other than ACES so the may be linear or log.
ARRI Alexa SXT
Blackmagic Ursa Mini-Pro
Canon C300-2 & Odyssey
Canon C700 4.5K
RED Helium 7K
Varicam LT & Odyssey
I’d recommend that you view these on your smartphone, it’s only 10.5GB in all and each file is at least 50MB but hey! your smartphone will easily cope with that!
If you do that you’ll see that there is absolutely no reason to get one of these cameras, your DSLR is way better and your iPhone better still.
Actually, I’m thinking of doing a similar test with some DSLR’s, I’d rather eat my own leg but I feel I have to do it just to prove a point.
On the other hand, maybe I’m wrong, maybe a $2K camera is really as good as a $60K one. If you believe that I’ve got this bridge you may want to buy…
Oh and just in case… load these files into Resolve with it set to ACEScc and 4K DCI, then set the input to ACEScc and the output to 709, don’t crop the image, move around it using the positioning controls in color.
This will let you look at the full beauty, or horror, of each file.
Yes, they all pretty much capture it all, well, a couple of horrors at the top end but you’ll find those for yourself. Now, look at the lower exposures and ask yourself how much noise and colour shift you can live with. You now have the USABLE dynamic range. Strangely enough it’s not always what it appears to be or what manufacturers say it is.
Well, I’ve uploaded QT files of all the cameras in HD and all the ones shot RAW in UHD as well.
They can be downloaded in their full unaltered by Vimeo form as well.
So how are people viewing them?
So far 606 total idiots have viewed them on their smartphones!
Unsurprisingly the Ursa Mini-Pro and the Canon C200 are the most popular however they also have the highest number of not completed viewings.
People viewing the evaluations via CML watch the videos to the end and tend to watch them at higher resolutions and download the original files far more than people going in directly to Vimeo or via other sites.
Why start viewing a camera evaluation if you’re going to give up after the first few exposures? one camera I can understand, you didn’t realise what was involved but the same person doing this on camera after camera? what kind of person does this, certainly not anyone who knows anything about cinematography. Anyway, WTF are you doing viewing them on a smartphone?
I will still go ahead and upload some EXR’s for the people who understand what their doing, precious few though it is!
I must be in an alternative universe, I just can’t believe what I see and hear.
11 years ago I shot a movie digitally, it was shot in HD in true RGB and uncompressed. Each of the 3 sensors had 1920 * 4320 photo-sites that created 3 * 1920 * 1080 images. It was 10 bit log and 4:4:4 generating 447.45 GB per hour.
Now Netflix are specifying that they will only accept “4K” cameras but they’re not 4K, they’re 2K * 2K in green and 2K * 1K in R&B they’re barely 3K and that gives you with Redcode 5:1 a grand total of 189.10GB per hour. It’s not a problem of Redcode, it’s just it was easy for me to get those figures, all the cameras they accept produce similar data rates.
Now I accept that technology moves on and compression get better but 4 times the resolution and less than half the data! no chance.
The issue is that people making decisions don’t understand what they’re deciding and are swayed by marketing.
The lunatics are truly running the asylum.
This is now the 4th day I’ll be wasting bouncing from support desk to support desk.
It’s never “their problem” it’s always the other guys.
I am in the ludicrous situation of having to go to a public Internet facility to be able to log on to our list server.
My ISP Ziggo says it’s not their problem, it’s a problem with the sites SSL, so why does it only effect me and why only the lists, which are not SSL, and not the main site which is SSL?
Dudobi who run the listserver say it’s all fine.
NetworkSolutions who are the main system provider say it’s all fine.
So if everything if so fine why have our pages listed on Google dropped from 2,500 or more to 94?
Why can’t I get connected to the listserver from home?
Sometimes I just want to pop round and give them a smack, difficult when they’re in the US, UK and Netherlands.
I’ve just received notification from NLPost that they have a parcel for me from Ziggo, I expect it’s the new Modem that I don’t need but id their standard response, change the modem.
Short term it’ll cost a fortune to install fast commercial fibre and install servers here but long-term it may be the only way to keep my sanity!
Why is it in a time of great depression that most of the scripts I get for films made in and about Britain are so profoundly depressing?
I realise that they are an accurate slice of these people’s lives, they reflect current life in the North and Midlands of England.
But the audiences live those lives! they don’t need to see them coming back at them from a big screen.
In the 30’s during the great depression the most successful films were ones that took people out of their depressing and hard real lives and gave them some hope.
Maybe not even hope, maybe just a few hours escape.
Busby Berkeley, the Gold Diggers series and Foot-light Parade, just sheer indulgence and fun.
Producers, Directors, look around, the successful films in the UK are happy ones, Billy Elliott, The Full Monty, 4 Weddings, Bridget Jones.
Are they art? who gives a damn!
They entertain people and make money.
Please send me a happy script…
