Firstly, I'm pretty stoked about the huge improvement in image quality, not in the least because it was free. To put things in perspective this firmware has allowed 5D users to do things that only very expensive cameras do, such as the Canon 1D-C, Red Epic, Arri Alexa - that is, shoot/record in RAW. Black Magic continue to challenge the big brands with their competitively priced camera range, but they utilize a much smaller sensor than that of the 5D. The ML firmware has certainly super-charged these little units meaning the 5D (mk3) once again punches well above it's weight.
Check a single frame of raw footage and a 100% crop of that same image...
Clarity and Sharpness remain since by-passing the compression of the standard H.264 codec.
NZ is famous for the harshness of our sun and filming in the middle of the day it's hard to avoid extreme contrasts in light. Frequently skies blow out or shadows lose all detail. The image below was also taken from the RAW footage. I exposed for the highlights thus crushing the blacks. When 'developing' the raw file I was pleasantly surprised to find plenty detail retrievable in the shadows.
Workflow. Here comes the negative of working in RAW. The Raw files are many times larger than consumer codecs such as H.264 so you need bigger cards, greater storage and faster chips to deal with them. Larger file sizes takes us back to the days of offline/online editing when the computers weren't fast enough to handle the full resolution images. I'm sure raw movie files won't be an issue for pc's of the future but for now at least the process must be broken down into a number of steps. For this test I did the following:
1. Renamed files using Actions app.
2. converted RAW files to DNG's using RAW2CDNG app.
3. Imported files into Davinci Resolve.
4. Exported files as MXF files and an AAF to Avid MC.
5. Edited movie in Avid.
6. Exported AAF from Avid to Resolve.
7. Graded footage. in Resolve
8. Exported AAF to Avid.
9. Exported final movie.
I am still ironing out the wrinkles in my workflow. i.e. problems round-tripping AAF's to and from Avid and Resolve. The annoying teething problems will disappear once a solid workflow is established.
Davinci Resolve. Resolve is quite different in its layout to other programs I've worked with so it took me a while to get my head around it. Upgrading from version 9 to 10 also set me back a bit. BTW You have to upgrade to version 10 to be able to work in the BMFilm color space. I have only scratched the surface with this software and look forward to learning all the quick keys etc to get some good flow going.
Magic Lantern Firmware. To be honest I haven't fully investigated the functionality of this firmware except for the RAW aspect but overall it has been very stable without freezing once. I like how the firmware sits on the SD card and isn't permanently installed on the camera. The RAW module needs to be activated each time the camera restarts so set your automatic shut down to 5 or 8 minutes. I forgot to activate the RAW a few times and just shot H.264 and had no idea until afterwards. Playback of recorded RAW files is limited to the last file recorded. There was no message to say the card was full it just keep trying to record again but would stop and say skipped frame at...
Transcend 64GB 1000x. These cards are awesome. I had no problems at all and they performed as they should. Being in NZ Komputerbay was not an option so these were the next best thing and probably better.
Lenses. I used two main lenses for this test - canon 50mm f1.4, canon 135mm f2.0 L. Your lens choices are going to influence the look of your movie no matter what camera of what format you shoot in. The last lens I bought was the Canon 24-105mm f4 L which was sufficient when I was shooting H.624. The heavily compressed images were not inspiring me to invest in better glass. Now that I can see real clarity and greater detail I am once again seriously contemplating that perfect prime lens.
ND Filters. One thing I disregarded completely for this test was the shutter speed. Although I have ND filters I wanted to keep the test as simple as possible. As a result the shutter speed often rose towards the upper limit of 4000 meaning movement looked less filmic and more hip hop music video. For any serious work I would probably go for a matte box and some quality ND's.
