I’ve just posted a full review of the Atomos Ninja 2 which I’ve been using with the Canon C100.
Canon have released firmware 188.8.131.52.00 for the Canon EOS C300, and thankfully this time it’s downloadable and installable by the user. Thi release includes the fix of the green fringing on high contrast edges that was also seen in the 184.108.40.206.00 release. Interesting is the mention of EF lenses being controlled more reliably, there’s no details of which lenses are effected.
Here’s Canon’s actual change log…
1. Some of the EF lens products that can be mounted on the camera can be controlled more reliably.
2. Corrections to the Spanish and German language texts in the View Assistance function [View Assist.].
3. Efforts to correct image color fringing when a subject is of high contrast have been made.
I sent my Canon C300 in to have the latest firmware installed by Canon UK, the 220.127.116.11.0 firmware contains a fix for the green fringe issue that I reported when I first got the C300. Interestingly it also changes the way the camera’s colour balance is set up slightly so I’ve had to update my custom picture profiles that are designed specifically to match the C300 with the C100.
I haven’t posted many updates lately so sorry for that. I’ve been working on a project involving a lot of two camera interviews using my Canon C100 and C300. This has been a good test for the profiles I created to match the camera and so far it’s going really well, the images from each camera are really close and I’m finding that with careful setup of exposure the results cut together well with the same grade applied.
The one thing that seems to let the the C100 down slightly is of course it’s internal 4:2:0 codec writing at 24MB/s, this doesn’t hold up as well as the C300‘s 4:2:2 codec at 50 MB/s. Below are some frame grabs showing one of the interviews I’ve shot and you will notice that although the C100 close up looks very similar to the wider C300 shot, closer inspection reveals compression artefacts that become more apparent when the footage is graded.
Both cameras were shooting in log with a minimal grade applied as an adjustment layer in Premiere CS6. I used Premieres RGB curves effect to add a shallow S curve and added some saturation using the fast color corrector tool. I’ll need to spend more time on the grade later in production but for now this gives a rough idea of how it effects the compression artefacts. Both the ungraded and graded screen grabs are shown below.
I’m going to be reviewing the Atomos Ninja-2 external recorder over the next few weeks to see how that improves the images from the C100. Because the camera outputs 4:2:2 over the HDMI port that should in theory produce results much closer to the C300. Watch this space for more on that very soon.
Ive spent some time working on custom picture profiles for the Canon C100 and Canon C300 cameras that allow both cameras to be cut together and match well. I don’t own test charts but I’ve tested these under various conditions and they match well. The following examples were shot using the built in tungsten setting on both cameras, manual white balancing or dialling in Kelvin settings on both cameras can produce non balanced results so I prefer to use the presets for two camera shoots when possible.
This is a neutral custom picture that has similar results to having no custom picture at all with the exception that the sharpness is dialled down to -5 on both cameras and the WB levels are tweaked on the C300 so that both cameras produce a similar colour balance.
I developed this custom picture profile mainly for my Harley-Davidson projects but it’s proved useful for a lot more than just event work. Canon Log definitely gives you more dynamic range and options in post but with fast turn around projects I prefer to shoot with a profile that produces more of a baked in cine look. There’s a CINE1 Gamma applied to give a bit more contrast and I’ve used a normal1 colour matrix so that the colours pop a little rather than a CINE matrix which would result in more muted colours.
The images below are obviously not designed to highlight the look of the custom picture, they are more to show how the C100 and C300 profiles match colours. To see what the custom picture looks like have a look at some of my recent videos.
The custom picture files can be downloaded below. Please note that the firmware update 18.104.22.168.0 that has to be installed by Canon changes the way colour is handled on the C300 so there are different versions of the files.
For C300′s with 1.0.6 and earlier - downloaded here - last updated 6-12-2012
For C300′s with 1.0.7 firmware – download here - last updated 12-2-2013
Please come back and let me know how they work out, good or bad any feedback will help to develop the files further.
This is based on mac, windows should be similar but I don’t have a windows machine so I can’t be sure. Please note that these custom profiles use the first positions on the card, if you have others in those positions that you wish to retain you will need to back them up prior to installing these.
1. With an SD card inserted in the C100 copy one of the standard custom picture profiles from the camera to the SD card using the transfer option with the custom picture menu. This just creates the required folder structure, if you already have custom picture settings on the card then this isn’t required.
2. Eject the card from the camera and mount it on a computer. You will see a main enclosing package called ‘PRIVATE’, right click on that and choose ‘show package contents’.
3. Now you should see a folder named C_PICT, place the C100 picture profiles in that folder and then eject the card.
4. Re-insert the card into the C100, go to the custom picture menu and either select the profiles direct from the SD card or copy them to the camera.
