DSLR cameras like the Canon 5D Mark II are changing the way people look at HD acquisition, but be careful, the camera doesn't do everything. Many people, both professionals and amateurs, buy a 5D to get the "film look". How do I get the "film look" is the lingering question. The 5D is a good basis but it doesn't do it itself! You need a story and many technical stuff, 24 frames per second shooting, good composition, shallow depth of field, professional lighting, camera equipment, prime lenses... The list is bigger but my point today is that one thing is often missing : Color Grading!
The image is not as beautiful coming out of the camera but you will have something far more beautiful at the end of the color grading workflow. I edited my last short films Russian Sandglass and Barely Legal Stories in FCPX and I love the way you can make adjustments to the colors. You have an independent control of the shadows, midtones and highlights during all the process (color balancing, brightness / contrast and saturation adjustments).
Let's go further! What is the best workflow? What is the most efficient way to work with color correction in NLE softwares like FCPX? You know what... here is the perfect resource for you! You probably know the Color Grading Central web site. If not... It's not too late, this is by far the best free tutorial I've ever seen on this subject. It takes only 30 minutes to watch all the videos. If you don't have the time, just watch the 2 following videos. It will make you want to see the complete color grading training.
I use the same workflow all the time : setting focus exposure > setting dynamic range > color balancing > shot-to-shot matching > looks building. Technicolor CineStyle helps to get the best dynamic range. You have more latitude when you set the proper exposure correction between 0 and 100 on the waveform scope of each specific shot.
Editing in FCPX is really a good experience but I had many problems to get the best result as possible (clear shots) only with FCPX and Compressor (which is just unusable for me at this time). I have always an Avidemux step in my workflow. Avidemux is an open source project with many cool editing features. For instance, I like to apply my last gama correction in Avidemux with a filter called "Mplayer eq2" and my favorite companion is a filter called "Mplayer Hqdn3d" to remove the noise at the end of the process (very useful with the CineStyle).
I hope it could help make things look better than they really are. Don't hesitate to give your opinion and to share your workflow. What do you do to create the best possible image in post?
