Should I Upload Shutter Stock Footage in Log or Colored
Color grading is how you enhance or change the colour of a video, motion picture, or image. Let's explore color profiles, LUTs and how to colour class.
There are many elements that piece of work together to make a video special but color grading can completely transform the look. Whether subtle or ultra-stylized, how you color grade is optional and depends on your artful. Then, what exactly is colour grading and where should you lot start?
What is Color Grading?
Colour grading is how you heighten or alter the colour of a motion-picture show, video paradigm, or withal image. It's how videographers adjust the colors of their footage to achieve a visual mood or tone.
Color grading was once called color timing, a process done manually while developing bodily motion-picture show. Color adjustments were made past manipulating how long the film was exposed to the dissimilar developing solutions.
While the term colour grading refers to the whole process of adjusting the color from the source file to the final output, the procedure is split into two parts:
- Color correction: The process of adjusting the bones colour and white balance, exposure, and dissimilarity to be consistent from shot to shot.
- Color grading: One time the color has been corrected, the footage tin be colour graded to fine tune the colors and create a specific look.
A common example you've likely seen in films is to add teal to adumbral areas and orange to the midtones.
Camera Colour Profiles
When a camera records a scene, it collects digital data and so translates that data into a viewable format. When information technology does this, information technology includes instructions on how to modify the data in some style to effort and more accurately recreate what you saw.
However, no photographic camera is able to exercise this perfectly, so this is where color profiles come up into play. Colour profiles work similarly to white balancing, simply as well conform elements like saturation and contrast.
Usually color profiles are sufficient for casual situations like taking a quick video of your friend'southward soccer game. However, videographers need far more control over their footage.
Most cameras will offer a flat or log profile. In a log color profile, the camera minimizes the contrast in social club to clasp in the most information possible. This helps to avert blowing out highlights or clipping shadows, also equally flexibility when editing your video after.
If your camera doesn't offering a log profile and you lot plan to color grade your video, utilize either a neutral contour or set up a custom contour with the sharpness and contrast set as low as possible. It can also aid to slightly decrease the saturation setting.

LUTs were once used when sending video from editing to impress. Unlike types of moving picture react to development differently. They ensured the printed film matched the monitors where the colour correction took place. Without a LUT, no affair what colour correction and grading procedure was used, the concluding video colors would exist unpredictable.A LUT is a set of math-based directions used to modify RGB values that changes a video's hue, saturation, and brightness.
While few video creators (with the possible exception of Hollywood filmmakers) volition ever put their videos onto physical film, the LUT process has nonetheless continued. There are two general types of LUTs that digital video editors will use: technical or normalization LUTs and creative LUTs.
Technical or Normalization LUTs
Near videographers are going to utilise a log color profile in order to capture the most possible information. Straight out of photographic camera, this footage is going to be flat and done out.
A normalization LUT converts the log image into another color space. It adds back the contrast and saturation compressed during recording. Information technology might, for instance, convert information technology into a Rec. 709 contour in guild to match the standard for HDTVs.
Photographic camera manufacturers often supply technical LUTs for their proprietary log profiles. At that place are likewise 3rd-party creators developing LUTs they feel are amend.
Creative LUTs
Another common blazon of LUT are creative LUTs. They utilise a set of adjustments to dissimilar color levels in order to create a specific wait or effect. A artistic LUT is similar to a preset that a photographer would apply to a flick in Photoshop or Lightroom.
How to Color Grade
The color grading procedure will vary somewhat from editor to editor, but here is a general workflow you can follow:
-
- Normalize Your Video Clips
- Perform Video Color Correction
- Color Grade Your Footage
- Perform Final Color Adjustment
- Consider Vectorscopes and Skin Tones
Normalize Your Video Clips
The offset step should be to normalize your video clips. Y'all need to gear up the contrast and saturation in social club to take advantage of all of the information recorded. Information technology's possible to practise this process manually, or you can employ a technical LUT to simplify your workflow.
Perform Video Color Correction
Once your clips have been normalized, you need to colour correct the video. Try to get the video clips as "correct" equally possible. If your exposure is bad, contrast is missing, or white residual is off, the actual color grading will be far more than hard.
Color Form Your Footage
In one case your colour correction is completed, yous can then colour grade your footage. Again, this step can be done either manually or with a LUT. Doing it manually volition provide y'all the about control merely could take longer. Using a creative LUT tin save fourth dimension and add consistency, only only if all of your clips are color corrected well.
Perform Last Colour Aligning
Every bit with any automated method, LUTs are likely to not be perfect. For example, they might give everything too much of a certain color tint. Subsequently adding your LUT, go back through, correct whatever bug, and ensure consistency across all of your clips.
Vectorscopes and Skin Tones
1 of the challenges with color grading video is that yous tin can't always completely trust what you lot encounter on your monitor. Bad (or the lack of) monitor calibration and ambient lighting can modify the style y'all run into the video being displayed.
How can you make sure that your color corrections are accurate?
Editing programs that offer video color correction tools, such equally Adobe Premiere Pro, DaVinci Resolve, and Last Cut Pro offering solutions for this problem. Within these programs, in that location are panels chosen scopes that requite a range of information about your video footage. FilmConvert is a helpful color grading software parcel to consider.
When it's time to color right or color course, the vectorscope is extremely helpful. A vectorscope shows what color tones y'all accept and how saturated they are. Because the vectorscope directly reads the digital signal, it'southward not afflicted by anything that might skew your perception. One time you learn to read them, they requite you colour information that you can trust to be accurate.
One of the nigh helpful features of a vectorscope is a line that passes between the yellow and blood-red points. If it was a clock face, the line would go from roughly 11:00 to 5:00. This is called the peel line, considering virtually every person'southward pare tone will autumn on or extremely shut to this line.
When color correcting, ensure that your colors are balanced so that the peel tones friction match upward with the peel line.
For whatsoever videographer who wants to produce loftier quality content, at that place are many elements to pay attention to. Framing, focus, exposure, capturing clear sound, and telling an engaging story are crucial. With all of this in place, color correction and color grading play an of import, final office in taking your video to a professional level.
