This effect is probably closest to the sort of appearance that you get when looking through a fogged window. Originally called "Ghost blur", it has now been enhanced by the addition of a fogginess adjustment. The resulting effect is capable of generating some extremely ethereal looks.

Iris Bokeh is similar to Bokeh, but on steroids. It provides control of the iris (5 to 8 segments or round), the size, rotation, threshold and pretty much anything else that you're likely to need to adjust.

Masked blurkhaverMaskedBlur.fxStylizeAugust 30 2011December 23 2018

This blur can be switched between standard and big blur modes. The threshold can be adjusted, the mask can be derived from the luminance value or alpha channel of the source video or the mask can be from the luminance or alpha channels of another video track. There is also the option to blur the mask for smooth transitions between blurred and unblurred areas. This is a very powerful effect.

Masked motion blurbaopaoMasked_motion_blur.fxStylizeOctober 4 2015December 23 2018

This is an extremely strong directional blur. The blur angle can be adjusted through a full 360 degrees, and sampling can be adjusted to range from a succession of discrete images to smooth blur. An external mask input is available to control where the mask appears.

It would probably pay not to be too heavy handed when setting up the strength though.

This is a weighted directional blur. The blur angle can be adjusted through a full 360 degrees, and sampling can also be adjusted to reduce the blur to a succession of displaced images. Blur strength is adjustable from zero to roughly a quarter of the frame.

Soft foggy blurjwrlSoftFoggyBlur.fxStylizeJune 6 2017December 23 2018

This image is hidden for guests. Please log in or register to see it.

This blur effect mimics the classic "petroleum jelly on the lens" look. It does this by combining a radial and a spin blur effect. The spin component has an adjustable aspect ratio which can have significant effect on the final look. It uses the same technique as the soft spin blur effect.

Really just a directional blur, this effect is implemented using the same technique as the soft spin blur effect. As a result it gives a very smooth, soft result. The blur length, direction and density are all adjustable.

Soft spin blurjwrlSoftSpinBlur.fxStylizeJune 1 2017December 23 2018

This effect arose out of debugging work done on another user's effect, however this is entirely original work. The blur sample rate is extremely high, giving vastly improved smoothness compared to other blur techniques. This improvement is also partially a side effect of the blur arc technique having been changed. Unlike the earlier effect which applied a clockwise rotation, this effect uses a bidirectional spin. For example, a 30 degree arc will be produced by applying simultaneous 15 degree clockwise and anticlockwise blurs.

It's also possible to fade the effect in and out, and to adjust for any change of video levels that extreme amounts of blur can cause. If you're blurring a black to white edge the result will inevitably be grey. This adjustment attempts to partially compensate for that. That said, in the video below no level compensation at all has been applied.

Soft zoom blurjwrlSoftZoomBlur.fxStylizeJuly 6 2017December 23 2018

This image is hidden for guests. Please log in or register to see it.

This blur effect is similar to the Lightworks radial blur effect, but is very much softer in the result that it can produce. The blur length range is also much greater than that provided by the Lightworks effect. It's possible to move the blur centre to one corner of the frame and still have a smooth result at the diagonally opposite corner. It uses the same technique as the soft spin blur effect above. Play the video below to see the range of adjustment available.

This applies a rotary blur with adjustable aspect ratio and centring.

Strong blurjwrlStrongBlur.fxStylizeJune 30 2016December 23 2018

This image is hidden for guests. Please log in or register to see it.

Originally called "Super blur", this is a spin-off from a radially sampled blur tool developed for several other user effects. It can be used to produce extreme levels of blurring not readily achievable by conventional blur effects. The effect is very smooth in operation, and the blur mix level can be adjusted to give a very convincing mist filter effect for those times when you didn't pack the Promist. There is also a setting that closely mimics the range of the Lightworks blur effect, but is smoother.

However such smoothness comes at some cost. Because each pixel can be sampled up to 240 times if you have a low performance system this effect may choke.

Tilt shift doesn't create the distortion of a tilt-shift operation, but does produce the blur component.

Unsharp maskjwrlUnsharp_mask.fxStylizeJune 6 2017December 2 2018

This image is hidden for guests. Please log in or register to see it.

This effect was originally by soundandvisionunit and based on khaver's Big Blur, and was designed to help sharpen an image. That version has now been withdrawn since it was fundamentally flawed and couldn't be made to function cross-platform. A new version which uses similar design principles has been created, and does operate cross-platform. The parameters used are slightly different - one (blur x 5) has been withdrawn and two new ones (edge gain and edge gamma) added in its place.

Be warned: this is an extreme effect. Unless you really can't get what you need with either of the Lightworks sharpen effects it probably would be better to use one of those.

Border creates a coloured hard border over a cropped image. The border is created inside the image being bordered, meaning that some of the image content will be lost.
