Section 4: Effects
In this section we look at everything to do with effects. This includes picture in picture effects colour correction and grading, applying masks, slow motion and image stabilization.
The basics of effects
In this section we look at the main features of applying and keyframing effects. We also include information on EDIUS’ downscaling options.
An introduction to effects
The best place to start learning about effects..
Some important user settings
If EDIUS cannot play the effect back you will have to render it to see it properly.
The buffer uses your computer’s RAM to make complicated effects as EDIUS plays.
A particular type of effect that goes on EDIUS’ keyer track.
You can remove lots of effects from many clips at once easily.
Shortcuts to add effects
There are many different and quick ways to add effects.
If you have a setting you like, save it as a preset to use in future projects.
Customising Effects folders
Reorganise the folder list of effects and make your own folders.
Effects presets in EDIUS 7
Grass Valley’s own presets appear in a different place in EDIUS 7 compared to previous versions.
To make an effect change over time you need to keyframe it.
Not all EDIUS’ effects can be keyframed. You can use blend effects to fade them up and down instead.
Very useful in filters like the mask tool, you can combine several effects into one.
If your computer cannot play the timeline you could use proxy mode instead.
Best quality scaling
EDIUS’ Lanczos scaling. Some of the best available.
Different quality settings
EDIUS has several different quality settings.
Downscaling HD to SD
How to use the Lanczos scaling to make a standard definition clip in the best quality.
8 bit or 10 bit effects
Most of EDIUS 7 effects are now 10 bit. What do we mean?
EDIUS can output alpha channels with most effects and this is important when keying and exporting.
Blue mark on filters
Some filters have a Blue mark. What does this mean?
Grading is the correct terminology for the topics in this section. Different ways to enhance, improve or even just rescue an image.
An overview of grading
With EDIUS 8 more grading features have been added and EDIUS has a wide range. Where should you start?
LUTs in the Primary Colour corrector
Adding a LUT is the easiest way to change the look of an image. You can add a LUT to change footage filmed in RAW format into “normal” footage or just to add a look to your video easily.
Adjustments in the Primary colour corrector
You don’t have to use LUTS with the Primary colour corrector - you can do a lot with the filter on its own.
Adding your own custom LUTS
One of the features added in EDIUS 8.22 was the ability to add your own LUTS. Here is how, and also how to adjust the intensity easily.
Hardware settings for the primary colour corrector
The Primary colour can use your graphic card to process the effect meaning you get better performance.
The 3 way colour corrector
One of quickest ways to colour correct your footage in EDIUS which may look daunting but correcting a shot could be as easy as making 3 clicks..
Using a reference picture
To match the colour of two shots you need to see both at once. The reference picture lets you do just that.
Our favourite way to brighten an image, the YUV curves gives you control over which parts of the image you change.
Waveform & Vectorscope
How do you judge if the colour is right? A properly set up monitor is essential but even then the picture can vary depending on what angle you view it and the light in the room. The Waveform display gives you an independent way to evaluate the brightness of image and the vectorscope evaluates the white balance.
YUV Curves & keyframing
Most effects can be keyframed. YUV curves can be keyframed but it does not work like everything else.
Using Blend Modes
Blend modes change the way one image will overlay on another and they can be used to quickly brighten an image.
Secondary colour correction
With secondary colour correction you can choose to change a range of colours or brightness levels rather than the entire image
The chrominance filter also lets you adjust a particular range of colours but as it is based on chromakey produces different results to using secondary colour correction..
The mirror effect lets you flip an image easily - if you “crossed the line” accidentally when filming, for example.
Another useful tool which will highlight areas of the image with a stripy pattern if they are over exposed.
EDIUS’ built-in titler has many useful features and is good for simple titles. For animated titles you may want an extra plug-in.
The basics of QuickTitler
Make a title and design your type face. Quick and simple..
Full quality all the time
In older versions of QuickTitler it would work in a low resolution mode when laying out the title and you would have to preview to see the title in its full quality. In EDIUS 7 you can enable full quality all the time.
If the title is on a title track you can use title mixers to fade or move the title. They are added automatically and easy to change, although there are only a few different styles.
You can draw basic shapes in QuickTitler such as boxes and spheres, and change the properties as you would a piece of text.
There are some useful windows in QuickTitler which are generally turned off. These let you centre a title or see the text in a different way..
Rolling titles and styles
It is easy to make a rolling or crawling title in QuickTitler and you can save text styles for use later..
QuickTitler does not do animation in the way an add-on like VisTitle can, however you can animate titles with EDIUS’ layouter and some imagination.
If you copy a title and change the copy you change both the copy and the original. If you do it the right way you can easily copy a title and make a new version without changing the original.
EDIUS’ has a large range of 2D and 3D transitions apart from the most commonly used dissolve. They can all be thoroughly customised and even used as effects.
The basics of transitions
How to apply a transition, and the effect it has on clips around the edit point.
Start or end of cut?
If you drop the transition in the right place you can decide whether it covers both clips equally, or starts or ends at the cut point.
The default transition
For most people the standard cross dissolve is the best default transition but you can change it to any transition you like and you can customise the length.
“A” & “B” track view
In old edit programs there was an A and a B track and transitions could be dropped between them. It is possible to work like this in EDIUS with one or two exceptions.
EDIUS has a huge range of transitions including some powered by your computer’s graphics card - called GPU transitions. All can be extensively customised.
Transitions as effects
You can drag a transition out to cover an entire clip and then by customising the transition use it as an effect rather than a simple change between scenes.
EDIUS’ layouter is a filter which can be used for picture in picture, image pan and resize effects as well as the way to work out what happens when your video does not match the timeline.
The basics of the layouter
The layouter is on every clip and you use it for any resizing effect you need.
More about keyframes
In the basics of effects we explained the simplest aspects of keyframing. Now we look further into the subject.
The way a clip moves through keyframes is called keyframe interpolation. You can even customise it completely.
Many other options of the layouter including borders and useful alignment tools.
You can crop the clips in layouter as well, and animate the cropping.
The layouter does 2D and 3D movement. Just start the 3D option and twirl the clips around in 3D space.
You can save regular EDIUS effects presets for the layouter but it has its own preset section as well. You can also set the default action for all clips.
Aspect ratio in the layouter
Dealing with clips with different aspect ratios to the timeline you are editing.
Edge & drop shadow
New options that arrived with EDIUS 7 - you can feather the edge and add a drop show in the layouter.
The importance of layer order
The layouter is normally the first effect on any clip but it can be moved up and down in a stack of effects. It is important that you get the effects in the right order.
The mask filter
The mask filter can be used for a huge number of things. You can use it to “cut out” an area of an image or to focus a particular filter on just a single part of the video, or as a “witness protection” effect..
You can also use this effect to automatically track objects across the screen.
The basics of the mask filter
How to apply the mask filter, make unmasked areas transparent and set a filter inside the mask.
Rotoscoping is the procedure for “cutting out” part of an image an overlaying it on a different image. You have to draw the shape and then animate that shape as it moves across the screen.
A commonly requested effect, you can use the mask filter to blur or mosaic a persons face and add keyframes to make the mask follow them as they move.
Using a mask for image correction
Select and area of an image and apply an image correction effect to just that area. You can even combine several image effects into one.
Animate a shape
You can add a mask to a solid background and cut out a shape - in this case a curved arrow - which then moves over time by keyframing the mask
Added in EDIUS 8.2, you can get EDIUS to track a shape inside a mask across the screen. In this first chapter we examine the basics of tracking.
Tracking and sharpening a face
In this example we track a face and use this to selectively add sharpening to the face, rescuing an otherwise slightly out of focus shot.
Tracking a car number plate
In this tracking example we track a car number plate as it moves across screen and blur it.
Tracking a difficult shot
In this example we are tracking a man wheeling a buggy across the screen, however, the tracker finds it very hard to track his shape as he moves in and out of shadow, so instead we track something easier and then adjust the results so it tracks what we want.
EDIUS has a specific part of the clip where you add “keyer” effects, These are any type of effect that will adjust the transparency of the clip - from the obvious chromakey and lumakey to the track matte and blend modes.
Chromakey - set the key
Chromakey will take a specific colour and make it transparent. Blue or green are the most commonly used but it can be any colour. EDIUS has great tools for Chromakey and a lot of possible refinement. This this first section we talk about choosing the key colour and refining it.
Chromakey - cancel colour and keyframing
Cancel colour is referred to as spill suppression in most keying programs. The Chromakey effect can also be keyframed but this keyframing works in a different way to other effects..
Keying on the brightness value of an image. Remove all the really bright white areas for example and replace them with a different image..
These will be familiar to users of paint programs - they are different way of combining the image with one below it..
Take a clip and cut a hole in it based on a clip on a different track..
Moving and blurring the matte
You can animate the matte easily. In this example cut some words out of an image using a title as a track matte which then moves across the screen.
Speed and image stabilization
How to slow clips down and to achieve a ramp with the speed, as well as using EDIUS’ excellent image stabilizing filter.
How to change the speed
Adding a speed change to clip - either slow motion or fast..
Optical flow, frame blending and nearest neighbour
EDIUS has three ways of doing slow motion: Nearest neighbour, frame blending and optical flow. The latter generally gives the best results but not always as this section explains.
Optical Flow Options
You can set a default speed interpolation but it is not the best idea to choose optical flow even though the latter generally gives the best results.
If you want to stop the motion dead the simplest thing is a freeze frame - EDIUS has a great and simple option for this.
If you want to start the clip at one speed, then make it go faster, the slow down, maybe go backwards, then EDIUS’ time remapping is the thing you need.
The image stabilizer
Take wobbly footage and turn it into a steadycam shot with EDIUS’ easy to use image stabilizer.
Rolling shutter correction
Some single chip cameras can suffer from “wobbly vision” on fast panning shots where vertical lines before diagonal, caused by the movement of the camera and the single chip. You can use the EDIUS image stabiliser to cure this.
The OFX Plug-in Bridge
How to slow clips down and to achieve a ramp with the speed, as well as using EDIUS’ excellent image stabilizing filter.
The basics of the OFX plug-in bridge
The OFX bridge is an add-on which is not installed by default and lets you add in OFX plug-ins from other manufacturers. On its own it adds no new effects, you have to buy the OFX plug-ins as well.
NewBlue Titler Pro 2 trial
The OFX bridge is made by NewBlue for Grass Valley. It is free. With it NewBlue install a trail version of their titling program, NewBlue Titler Pro 2. Although this is a trial version it is a trial that lasts for a year, so you can get quite a lot of use out of it.
