Sony Vegas Pro comes with four Video Scopes and an extensive range of Video Effect plugins to help you Colour Correct and Colour Grade your Video and Still images.

Almost any video or still image that comes out of a camera, will benefit from some level of Colour Correction in Sony Vegas Pro or Sony Movie Studio Platinum. During this tutorial I will be using Vegas Pro 13, however Movie Studio Platinum users can still follow along and learn quite a lot. If you are a Movie Studio user, you will have many of the same Video Effect plugins that Vegas Pro users have, however you will not have access to Video Scopes which are a Pro feature only.

Colour Correction is a very large topic, so the purpose of this article is to give you a clear understanding of the basics and help explain the meaning of common colour correction terms. Once I have explained some definitions and theory, I will then take you through some real world examples of how to use Video Scopes with some of the Colour Correction Video Effect plugins.

Definitions for Colour Correction

The best place to start is to explain the difference between what Colour Correction and Colour Grading actually means.

Colour Correction can mean many things, but basically it is the process of fixing any problems with the exposure and colour of your original video or still image, so that it looks right.

Colour Grading is the process of altering and enhancing the colour of a video or still image, to create a particular look, feel and mood.

Tonal Range

Tonal Range = the range in Brightness Levels from the Darkest to the Lightest - Jet Black to Pure White.

Full Tonal Range extends from RGB values of 0, 0, 0 (Pure Black) to 255, 255, 255 (Pure White).

Understanding Tonal Range is at the heart of colour correction. The easiest place to start is in the world of Black and White. Once you understand Tonal Range expressed as Pure Black to Pure White, it is easy to understand colour in the same way, using the three RGB (Red, Green and Blue) colour channels that make up any colour image.

If the tonal range is quite narrow, the video image will look flat and lack contrast - basically a washed out looking video. Increasing the tonal range gives you whiter whites and deeper blacks, thus increasing the overall contrast of the image. Doing this often has a side effect of slightly increasing the saturation of your colours as well.

Video and DSLR Camera Recording Modes and Picture Styles

Many professional video cameras, DSLR cameras and the latest mirrorless cameras, have special Picture Profiles that allow you to deliberately record to a very flat or neutral Picture Style or Cine Style  - meaning a narrow tonal range. You may hear terms like S-Log being mentioned. This may seem counter intuitive to record your original video to a flat picture style, however it means that once you get your video into Sony Vegas Pro or Movie Studio Platinum, there is much greater scope to fully open up the complete tonal range, because the shadows and highlights have not been "baked into" the video at the extreme ends of the spectrum. So if you are lucky enough to have a really good camera that can shoot in these professional modes, learning how to do Colour Correction and Colour Grading is extremely important.

Broadcast Safe Colours

Quite often you will hear the term "Broadcast Safe Colours" being used. This refers to a limit being placed on the Full Tonal Range. This is very important for any video projects to comply with, if they are destined for playback on a TV Station. The reason for this relates more back to the days of analog TV broadcast through glass tube cathode-ray television sets. Colour values that exceeded the broadcast safe range, would display incorrectly on a TV and/or cause audio artifacts to appear. Modern HD Televisions can handle the full range just like your computer monitor, however the specification still remains in place world wide and does still seem to be needed.

Broadcast Safe Colours live between 16, 16, 16 (Safe Black) to 235, 235, 235 (Safe White).

Shadows, Mid-tones and Highlights

Shadows refers to luminance values for anything that sits in the lower third of the tonal range.

Mid-tones refers to luminance values in the middle third of the tonal range.

Highlights refers to luminance values in the upper third of the tonal range.


Gamma refers to Mid-tones. Changing Gamma will Brighten or Darken Mid-tones.

Video Scopes available in Vegas Pro

Vegas Pro comes with four different video/colour scopes which are designed to help you analyze your video and help you see exactly what is going on. Using these video scopes will make it easier for you to accurately adjust tonal range, brightness and contrast, hue and saturation, luminance values, gamma values, shadows, mid-tones and highlights. Don't freak out if you are already getting scared by some of these exotic terms. I gaurantee that by the end of this article, it will all make sense and you will have full confidence to dive in at the deep end of the colour pool. I am deliberately make it as simple as possible.

How to turn ON Video Scopes in Vegas Pro

Video Scopes are accessed by going to View - Window Layouts - Colour Correction.

Colour Correction should always be one the last tasks you complete when editing a video project. It is definitely not something you would do at the beginning, before you have sliced and diced your media on the timeline. Once you begin adding Colour Correction Video Effects to the timeline, your CPU will have to do a lot more work. Make sure to pick a good place in each video clip that represents the overall colour and brightness levels of the entire video. Now is also a good time to switch the Preview Window into one of the Best Modes, so that you are seeing the colour accurately while applying Colour Correction.


The Vectorscope plots Hue and Saturation.
Hue = what colour it is.
Saturation = intensity of colour.

The center of the scope represents zero saturation and no hue (no colour). The further away the dots are from the center, the more saturated the colours are. The six green target areas represent the three primary colours of red, green and blue and the three secondary colours of cyan, magenta and yellow. The center of each target represents the broadcast safe saturation level for that colour.

In example 1 below, all colours fall into the Broadcast Safe zone. If any dots appeared past the safe zones, the Vestorscope would be able to indicate me which Hue (Colour) needs adjusting.

*Make sure to turn ON Update Scopes While Playing, marked by red arrow below.

Example 1 - using the Vectorscope

This is some video I shot from the Sydney Vivid Light Festival, where powerful projectors shine video images onto the Sydney Opera House. All the colours are washed out in the original shot. You can see on the Vectorscope that all the dots are concentrated around the centre and they are relatively dispersed throughout 360° - indicating that there are many different hues (colours) present, but they are not very saturated.


So I then applied the Colour Correction plugin and boosted the Saturation.


Now you can see all the dots have spread out from the centre, which indicates all the colours are now more saturated. However there are no dots past the green target areas, so I know that the colours are still broadcast safe. In my experience, most video clips look better with at least a little bump in the Saturation.



The Waveform scope shows luminance values, which means it is indicating the brightness levels for your video.
Luminance value = Brightness levels.

Looking at the Waveform monitor from left to right corresponds exactly to looking at the Video Preview window from left to right. The higher the dots are vertically, indicates more luminance (brightness).

Example 2 - using the Waveform scope

In Example 2 I have shown another part of the same video from example 1. I have delibrately removed the Colour Correction I added above, so that we can see what the raw video looks like in the Waveform scope. Notice how squashed the waveform is ? Which is telling us the the video is very dull and lacks luminance.


I then applied just the Brightness and Contrast filter and pumped up the Brightness a little bit and the Contrast a lot.


Now the Waveform looks like it can breathe again and we can see a nice distrubution of luminance all the way from zero up to the 80% level mark. Without adding any Colour Correction, the video already looks 100% better than the original.



The Histogram displays the Brightness and Contrast of your video.
Brightness = Luminance value.
Contrast = the difference between light and dark.

The vertical lines starting from the left at "0" (0=black) represent luminance values and extend all the way to the right at "255" (255=white). The height of each line represents the number of pixels in the image that exhibit a particular luminance value.

Example 3 - using the Histogram

In Example 3 you can see that the image is flat and washed out looking. The Histogram shows that there are no true Blacks in the image and no True Whites, or you could also say that it is lacking Shadows and there are no Highlights. Everything is bunched up in the Mid-tone area.


I then applied the Brightness and Contrast filter.


Increasing the Brightness slider moved the entire Histogram output to the right. Increasing the Contrast slider expanded out the entire Histogram output , so now the image has visisble Shadows, Mid-tones and Highlights - giving the image more definition.


RGB Parade

The RGB Parade shows the Luminance (brightness) of individual RGB Components (colour).
RGB = Red, Green and Blue

This is my favourite Video Scope because you can quickly see the brightness levels for each of the three main colour components. If you could stretch out each individual colour band to match the same width of your Preview Window, you would clearly see the corelation between the scope and the image. When you watch the video tutorial at the top of this article, you will see exactly what I mean.

Example 4 - using the RGB Parade

In Example 4 you can see a very strong band of activity in the lower Mid-tone area. There are no pure blacks at the bottom and a large area of no highlights at the top of the spectrum. The tiny bit of activity you can see around the 192 line, represents the luminance of the white boat on the left.


I added Colour Curves to the image and created an "S-Curve".


The short bottom handle slightly pushed the image closer to true blacks. The longer top handle I created at the top, gave me the ability to stretch out all the compressed data that was sitting in the lower mid-tone region and also at the same time increase the overall luminance of the whole video. Colour Curves is definitely my favourite Colour Correction tool.

Using Colour Curves, you can also set it to just one Colour Channel if needed and change just that channel - either Red, Green or Blue. This can then be repeated for all three RGB Channels, so that each has it's own curve.


How to quickly make your project Broadcast Safe

There is a quick way to make sure your Output is Broadcast Safe, by applying the Broadcast Safe filter to the Video Output FX button above the Preview Window. Go to the Video Fx tab and drag Broadcast Colours - Extremely Conservative preset onto the output link. This will clamp everything down so that it does not go past the 16-235 range.

In the video tutorial I explain this in much more detail, so please watch if you want to learn more.



Best Colour Correction Video Fx

I have only touched on some of the Video Fx plugins you can use in Sony Vegas Pro and Movie Studio Platinum, for Colour Correcting and enhancing your video images. As I said at the beginning of this tutorial, Colour Correction is a huge topic full of many varied opinions. I am not a professional colourist, so what I am teaching you is the best of what I know right now. In the video tutorial I go over the core basics taught in this article and expand on a few areas I did go into detail with here.

The best Colour Correction Video Fx available to use are the following:

  • Brightness and Contrast
  • Levels
  • Colour Corrector
  • Secondary Colour Corrector
  • Colour Curves
  • Broadcast (Safe) Colours

I will definitely be making more advanced tutorials on this topic in the near future.

All the best with your projects and if you have any tricky questions, please use the new Movie Studio Zen Forum.

    Hello Derek, you were kind enough to help me a few years ago when I was just starting out with Vegas. I have been using the colour corrector but there remains in the lower right hand quadrant of each clip a bar which I think shows that portion with the original settings. I would like to eliminate this area in the finished clip but I can't work out how to do it. This is my retirement project and I am self taught and non technical so any advice in simple terms would be much appreciated.
    Thank You,
    John Jones

      Which exact version of Vegas are you using ?
      Which Colour Correction tool are you talking about ?
      If you are using the latest versions of Vegas and talking about the new controls that pop up under the Timeline, you need to select a video on the timeline first!

    Excellent video. I'm colorblind so learning how to use these color correctors through graphs instead of relying on my flawed vision really helps me understand what I need to do to make my videos better. Thanks for all your hard work!

      I never thought of that scenario before - very interesting indeed
      From my experience, it is also rare to find 2 people agree that they are seeing the exact shade of colour.
      When I see dark blue, others see purple and vice versa.
      Getting your monitor to be correctly calibrated, also helps - most monitors out of the box, are never set to more neutral settings required for Video Editing, however the Colour Scopes don't lie and I would be lost without them.

    Hi Derek.
    Enjoyed reading your article very much. Wondering if you know of a vectorscope plugin for magix Vegas Pro 15 that has a skin-tone line? Thanks!

      Hi Marc
      No I don't know about that.
      A lot of Vegas Pro experienced users and now using the free version of DaVinci Resolve t colour correct their projects.
      There maybe a third party plugin I don't know about. I would recommend you ask this question on the official Vegas Pro forums. If anyone knows that answer to your question, it will be there.

    Nice job Derek! I've been a broadcast video engineer for over 40 years and you've done a great job keeping the explanation simple that everyone can understand.
    I'm considering purchasing Sony Vegas Pro and have been playing around with a trial version. Regarding the waveform monitor, is there a way to increase the intensity of the display?
    Also, can you change the sweep from horizontal to vertical?
    Is there a plugin that can adjust sawtooth and Parab, both horizontal and vertical? I have some old film footage that could use Parab and saw help.
    Look forward to your response.

      Hi Doug - thanks for your comment.
      I'm not a big expert on Colour Correction, but know enough to get by.
      There is no way to increase the intensity of the Video Scopes - they are quite "old fashioned" looking in my opinion.
      If you open the Project Properties box, there are different settings for Motion Blur and Deinterlace Method.
      You may be aware that Vegas Pro is no longer a Sony product and the new owners are Magix.
      Because Vegas was left in limbo by Sony for a long time, development was halted, which has put Vegas Pro behind the pack in certain departments. The Colour Correction tools in Vegas Pro are in desperate need of an overhaul and I believe that Magix will be looking into improving these types of things.
      [i]Is there a plugin that can adjust sawtooth and Parab, both horizontal and vertical? [/i]
      I am really not sure about this one at all.
      To find someone with more in-depth knowledge than myself, I suggest you do one or two things.
      1. Post your message here on the official Vegas Pro Forums. There is a large community of pro Vegas editors on this forum and some of them will have direct experience with what you are asking.
      2. Another very good Vegas Pro Forum is on the Creative Cow Forums here:
      3. A couple of forum members on the Movie Studio Zen Forum (my forum), actually transfer film to video for a living. If you post a message here, one of them will hopefully see it and contact you.
      Many Vegas Pro editors use the free version of DaVinci Resolve to do their Colour Correction.
      BorixFX also makes very high quality plugins for Vegas (Open FX).

        Thanks Derek, I'll look into these forums.
        For some reason I can't get Resolve to work, keeps crashing. Says I don't have Cuda video card, could that be the reason?

          DaVinci Resolve really is a pro-level program and thus requires decent hardware to support the program.
          Resolve requires an above average Nvidia graphics card or AMD Radeon card.
          When I say above average, i'm talking about graphics cards that cost $200+ at a bare minimum.
          If you use Vegas software a lot, AMD Radeon graphics cards work far better with Vegas and will also work with Resolve or if you can get your hands on a 2nd hand Nvidia GTX500 series or older. Nvidia 500 series work extremely well with Vegas, however from 600 series onwards they don't work the same, due to an architecture change.
          Recently my graphics card blew up (old card) and I purchased a 2nd hand Nvidia GTX570 from eBay and it goes like a rocket with Vegas and Resolve.

      There is no target for the RGB parade, because it all depends on the colour present in scene.
      However, Broadcast Safe colours should fall between 235 and 16. If any of your RGB parade is way over or under 235/16, try to bring the levels down slightly.

    The same Video Fx plugins are available in MS13 but with the absence of any decent histogram tool or any of the analysis tools above shown in this article, you are correcting visually, not ideal. NMS13 should at include a histogram tool at least.

    Great article. Thank you! Very well explained and helped make sense of everything. Thank you for taking the time to go through it. One minor note: I believe in your explanation of the Histogram, 0 is actually black and 255 is actually white. (I didn't know much about the other scopes, but I do know histograms from my work in photography.) Thank you again for such a great article!

      Hi Jason
      Thank you for your message and indicating the error in article, which I have now fixed.
      I suffer from dyslexia and get left/right, black/white mixed up all the time. In my brain when I think the word white, I end up writing the word black, and vice versa. If I am a passenger in a car and someone asks whether to take a left or right, I can't trust the words that come out of my mouth, but instead use my hands which don't get mixed up.
